Implement a feature flag called courses-landing that will control whether the new "Courses Landing" page is visible.
Follow the example provided in the repository: Feature Flag Example.
Ensure that the flag can easily be turned on or off for testing purposes.
Create the Course Page Structure:

Within the /courses directory, create a new file for the page (e.g., index.tsx).
Set up the basic structure of the Courses Landing page, ensuring that it is modular and reusable.
Import the feature flag logic to hide/show the page depending on the value of courses-landing.
Mock Data Setup:

Create a new file called mock.ts in the /courses folder to hold mock data.
Define mock data for:
Course list (title, description, etc.)
User’s current progress in the courses.
Export this data so it can be used in the course page.

Data Population:

Import the mock data from mock.ts into the Courses Landing page.
Use this data to display a list of courses and the user's progress.
Each course should show its:
Title
Description
Progress bar (indicating user progress in percentage)
Responsive Design Implementation:

Use the provided Figma design to ensure the page looks correct on both desktop and mobile devices.

🧹 Outside diff range and nitpick comments (12)
app/(app)/feature-flag-example/page.tsx (1)

Line range hint 1-13: Summary of review for app/(app)/feature-flag-example/page.tsx

  1. The metadata title has been updated correctly, but the file location is inconsistent with its new purpose.
  2. The function name change to CoursesPage is appropriate and descriptive.
  3. The updated comment on session retrieval is clearer, but the necessity of authentication for this page needs clarification.

To improve this implementation:

  1. Consider relocating this file to a more appropriate directory, such as app/(app)/courses/page.tsx.
  2. Clarify whether authentication is required for the Courses Landing Page and remove the session retrieval if it's not necessary.
  3. Ensure that the feature flag logic is implemented as mentioned in the PR objectives, as it's not visible in this file.
app/(app)/feature-flag-example/_client.tsx (2)

9-12: LGTM: Feature flag updated correctly.

The feature flag has been correctly updated to FEATURE_FLAGS.COURSES_LANDING, which aligns with the PR objectives. The logic for handling the flag remains appropriate.

Consider updating the comment to be more specific:

- const flagEnabled = isFlagEnabled(FEATURE_FLAGS.COURSES_LANDING); // Adjust to the correct flag
+ const flagEnabled = isFlagEnabled(FEATURE_FLAGS.COURSES_LANDING); // Flag for controlling Courses Landing page visibility

16-18: LGTM: Return structure updated to render CoursesLanding component.

The return structure has been appropriately updated to render the new CoursesLanding component, which aligns with the PR objectives. The increased max width (max-w-6xl) suggests that the new component requires more horizontal space, which is consistent with a landing page design.

For consistency with the rest of the codebase, consider using an object destructuring pattern for the session prop:

- <CoursesLanding session={session} />
+ <CoursesLanding {...{ session }} />

This change is optional and depends on the coding style preferences of your team.

utils/flags.ts (3)

5-5: LGTM! Consider adding a comment for consistency.

The addition of the COURSES_LANDING feature flag is correct and aligns with the PR objectives. The naming convention follows the existing pattern, which is good for consistency.

For improved readability and consistency with other parts of the codebase, consider adding a brief comment explaining the purpose of this feature flag, similar to how other feature flags might be documented in the project.

 export const FEATURE_FLAGS = {
   FEATURE_FLAG_TEST: "feature-flag-test",
+  // Controls the visibility of the new Courses Landing page
   COURSES_LANDING: "courses-landing",
 } as const;

24-24: Improved comment clarity. Consider expanding the documentation.

The updated comment provides clearer information about the function's behavior in development environments, which is helpful.

To further improve the documentation, consider expanding the comment to explain the purpose of the disableDevCheck parameter. This will help developers understand when and why they might want to use this parameter. For example:

-    return true; // Always true in dev environments unless you want to test differently
+    // Always true in dev environments by default.
+    // Set disableDevCheck to true to test feature flag behavior in development.
+    return true;

Line range hint 1-27: Overall, the changes look good and align with the PR objectives.

The addition of the COURSES_LANDING feature flag and the improved documentation in the isFlagEnabled function enhance the feature flag management system without introducing breaking changes. These modifications support the implementation of the new Courses Landing page while maintaining consistency with existing patterns.

As the number of feature flags grows, consider implementing a more structured approach to feature flag management, such as:

  1. Grouping related flags into categories.
  2. Implementing an automated cleanup process for deprecated flags.
  3. Adding metadata to each flag (e.g., creation date, owner, expected lifespan) to aid in maintenance.

These practices can help manage the increasing complexity of feature flags as the project evolves.

components/Course/CourseCard.tsx (1)

7-9: Review dark mode styling for featured courses.

The conditional styling for featured courses looks good, but the dark mode background color (bg-orange-900) for featured courses might not provide enough contrast with the text. Consider using a lighter shade for better readability in dark mode.

You might want to adjust the dark mode background color for featured courses:

-      className={`rounded-lg p-6 shadow-md ${course.featured ? "bg-orange-100 dark:bg-orange-900" : "bg-gray-100 dark:bg-gray-800"}`}
+      className={`rounded-lg p-6 shadow-md ${course.featured ? "bg-orange-100 dark:bg-orange-800" : "bg-gray-100 dark:bg-gray-800"}`}
components/Course/mock.ts (1)

12-53: LGTM: Comprehensive mock courses data

The mockCourses constant provides a good variety of course data, covering different scenarios such as varying progress levels and featured/non-featured courses. The data structure correctly adheres to the Course interface.

Consider adding a course with 0% progress to cover the edge case of a newly started course.

components/Course/index.tsx (4)

1-9: LGTM! Consider adding prop validation.

The imports and component declaration look good. The use of mock data aligns with the PR objectives.

Consider adding prop validation using PropTypes or TypeScript's React.FC type for better type safety:

import { type Session } from "next-auth";

interface CoursesLandingProps {
  session: Session | null;
}

const CoursesLanding: React.FC<CoursesLandingProps> = ({ session }) => {
  // ... component logic
};

18-23: Good implementation of course list rendering. Consider adding empty state handling.

The courses list is rendered correctly using the map function, and each CourseCard is given a unique key, which is a good React practice.

Consider adding handling for an empty courses list to improve user experience:

<div className="lg:col-span-2">
  {mockCourses.length > 0 ? (
    mockCourses.map((course) => (
      <CourseCard key={course.id} course={course} />
    ))
  ) : (
    <p>No courses available at the moment.</p>
  )}
</div>

26-34: Featured advert section looks good. Consider future dynamic content integration.

The featured advert section is well-implemented with appropriate styling for both light and dark modes, aligning with the PR objectives.

For future iterations, consider preparing this section for dynamic content integration:

  1. Create a separate component for the advert, e.g., <FeaturedAdvert />.
  2. Implement a prop to accept advert content or an API call to fetch the latest advert.

This will make it easier to update the advert content without modifying the main component.


36-73: Excellent implementation of the latest progress section. Consider extracting the progress calculation.

The latest progress section is well-implemented with a visually appealing circular progress indicator using SVG. The display of course title and completion percentage is clear and informative.

To improve readability, consider extracting the progress calculation into a separate function:

const calculateStrokeDashoffset = (progress: number, circumference: number) => {
  return `calc(${circumference} - (${circumference} * ${progress}) / 100)`;
};

// In the JSX
<circle
  // ...other props
  style={{
    strokeDasharray: "251",
    strokeDashoffset: calculateStrokeDashoffset(userLatestProgress.progress, 251),
  }}
/>

This will make the code more maintainable and easier to understand at a glance.

8-8: Appropriate function name update

The function name change from Page to CoursesPage is a good improvement. It makes the code more descriptive and aligns well with the page's new purpose as a Courses Landing Page.


9-9: Clarify authentication requirement

The updated comment provides a clearer explanation of why the session might be needed. However, it's not explicitly mentioned in the PR objectives whether authentication is required for the Courses Landing Page.

Could you please clarify if authentication is indeed necessary for accessing the Courses Landing Page? If not, consider removing the session retrieval to keep the code lean.

To verify the authentication requirement, you can run the following script:

✅ Verification successful

Prepare a more flexible search for authentication enforcement in the codebase.

To improve the search, please run the following script:


<!-- [monologue]
[task verification_2/2]
The previous shell script identified multiple instances of authentication-related code across the codebase. To determine if the Courses Landing Page specifically enforces authentication, I need to inspect the `app/(app)/feature-flag-example/page.tsx` file for any conditional checks or redirects based on the session.

[observations]
- The `page.tsx` file retrieves the session using `getServerAuthSession`.
- There is a conditional check that redirects unauthenticated users to `/get-started`.

[analysis]
- The presence of a redirect when the session is absent indicates that authentication is enforced for the Courses Landing Page.
- This confirms that the session retrieval in the code is necessary and aligns with the authentication requirements.

[actions]
- Conclude that authentication is indeed required for the Courses Landing Page.
- Approve the comment change as it correctly reflects the purpose of session retrieval.
-->

Authentication is required for the Courses Landing Page

6-6: LGTM: Import statement for CoursesLanding component added.

The import statement for the CoursesLanding component is correctly added and aligns with the PR objectives of implementing a new Courses Landing page.


Line range hint 1-24: Overall implementation aligns well with PR objectives.

The changes in this file successfully implement the feature-flagged Courses Landing page as described in the PR objectives. Key points:

  1. The feature flag has been correctly updated to COURSES_LANDING.
  2. The CoursesLanding component is properly imported and rendered.
  3. The container's max width has been increased to accommodate the new landing page design.

These changes provide a solid foundation for the new Courses Landing page while maintaining the ability to toggle its visibility using the feature flag.

To ensure the CoursesLanding component is implemented correctly, let's verify its existence and basic structure:

components/Course/CourseCard.tsx (3)

5-5: LGTM: Component definition and props look good.

The CourseCard component is well-defined as a functional component with proper TypeScript typing for its props.


34-34: LGTM: Component export is correct.

The default export of the CourseCard component is properly implemented.


1-34: Overall, the CourseCard component is well-implemented.

The component structure, styling, and TypeScript usage are good. Consider the suggestions above to further improve type organization, dark mode contrast, and button functionality. These changes will enhance the component's reusability and user experience.

components/Course/mock.ts (2)

3-9: LGTM: Well-structured Course interface

The Course interface is well-defined with appropriate types for each property. It covers all the necessary attributes for representing a course, including an identifier, title, description, progress, and a featured flag.


1-78: Overall, well-structured mock data file with minor improvement suggestions

This file provides comprehensive mock data for the courses feature, including a well-defined Course interface, a variety of mock courses, and user progress data. The structure and content are generally good, serving the purpose of simulating course data for development and testing.

The suggestions provided earlier, particularly regarding the userProgress constant, would further improve the consistency and maintainability of the mock data. These improvements would make the file more robust and less prone to inconsistencies as the feature develops.

components/Course/index.tsx (2)

11-17: Great job on the responsive layout!

The main layout structure is well-implemented:

  • Responsive design using Tailwind CSS classes
  • Proper implementation of dark mode
  • Grid layout that adapts to desktop and mobile views

This aligns perfectly with the PR objectives for responsiveness and theme consistency.


1-80: Overall excellent implementation of the CoursesLanding component.

The component successfully meets all the requirements outlined in the PR objectives:

  1. Implements a responsive layout using Tailwind CSS.
  2. Correctly uses mock data for courses and user progress.
  3. Includes sections for course list, featured advert, and latest progress.
  4. Supports both light and dark modes.

The code is well-structured, follows React best practices, and is typed correctly with TypeScript. The suggested improvements in previous comments are minor and aimed at enhancing maintainability and user experience.

Great job on this implementation!

⚠️ Potential issue

Inconsistency between page title and file path

The metadata title has been updated to "Courses Landing Page", which aligns with the PR objectives. However, the file is still located in the feature-flag-example directory. This inconsistency could lead to confusion.

Consider moving this file to a more appropriate location, such as app/(app)/courses/page.tsx, to match its new purpose. If you decide to keep it in the current location, please provide a comment explaining why it remains in the feature flag example directory.

🛠️ Refactor suggestion

Consider moving the Course type to a separate types file.

While importing the Course type from ./mock works for development, it's generally better to separate types from mock data. This improves code organization and makes it easier to maintain types across the application.

Consider creating a new file, e.g., types.ts, and moving the Course type definition there:

// types.ts
export interface Course {
  id: string;
  title: string;
  description: string;
  progress: number;
  featured: boolean;
}

Then update the import in this file:

-import { Course } from "./mock";
+import { Course } from "./types";

⚠️ Potential issue

Add functionality to the "Start Course" button.

The course content is well-structured and styled. However, the "Start Course" button currently lacks functionality. Consider adding an onClick handler to make the button interactive.

You could modify the button as follows:

-      <button className="mt-4 rounded bg-orange-500 px-4 py-2 text-white hover:bg-orange-600">
+      <button 
+        className="mt-4 rounded bg-orange-500 px-4 py-2 text-white hover:bg-orange-600"
+        onClick={() => {/* Add your logic here */}}
+      >
        Start Course
      </button>

Also, consider passing a callback function as a prop to handle the button click, which would allow the parent component to define the behavior:

interface CourseCardProps {
  course: Course;
  onStartCourse: (courseId: string) => void;
}

const CourseCard = ({ course, onStartCourse }: CourseCardProps) => {
  // ...

  <button 
    className="mt-4 rounded bg-orange-500 px-4 py-2 text-white hover:bg-orange-600"
    onClick={() => onStartCourse(course.id)}
  >

🛠️ Refactor suggestion

Consider refactoring userProgress for consistency and maintainability

While the userProgress constant provides useful mock data, there are a few points to consider:

  1. The data structure uses courseTitle instead of id to identify courses. Using id would be more consistent with the Course interface and less prone to errors if course titles change.

  2. There's potential for inconsistency between mockCourses and userProgress if the data is updated in one place but not the other.

Consider refactoring userProgress to use course IDs and create a function to generate it from mockCourses:

export const generateUserProgress = (courses: Course[]) => ({
  coursesProgress: courses.map(course => ({
    courseId: course.id,
    progress: course.progress,
  })),
});

export const userProgress = generateUserProgress(mockCourses);

This approach ensures consistency between mockCourses and userProgress, and makes it easier to maintain the mock data.

Refactor the CourseCard component to include a new prop `onStartCourse` and update the import paths for the `Course` type. This change allows for starting a course when the "Start Course" button is clicked.

🧹 Outside diff range and nitpick comments (6)
components/Course/type.ts (1)

1-7: LGTM! Well-structured interface for Course objects.

The Course interface is well-defined and aligns with the PR objectives. It provides a clear structure for course objects to be used in the new Courses Landing page.

Consider the following minor improvements for clarity and robustness:

  1. Add a comment for the progress property to specify its range (e.g., 0-100 for percentage).
  2. If there are any specific constraints on the id format, consider using a more specific type (e.g., UUID).
  3. Evaluate if any properties (like description) could be optional, depending on the application's needs.

Example implementation:

export interface Course {
  id: string; // Consider using a more specific type if there's a format constraint
  title: string;
  description: string;
  /** Progress percentage (0-100) */
  progress: number;
  featured: boolean;
}
components/Course/index.tsx (2)

1-7: LGTM! Consider destructuring the session prop.

The imports and component declaration look good. The use of TypeScript for type safety is commendable.

Consider destructuring the session prop directly in the function parameters for cleaner code:

-const CoursesLanding = ({ session }: { session: Session | null }) => {
+const CoursesLanding = ({ session }: { session: Session | null }) => {

13-30: LGTM! Consider adding an aria-label for better accessibility.

The component render logic looks good. It follows responsive design principles and correctly uses Tailwind CSS for styling, including dark mode support.

For improved accessibility, consider adding an aria-label to the courses grid:

-      <div className="grid grid-cols-1 gap-8 lg:grid-cols-2">
+      <div className="grid grid-cols-1 gap-8 lg:grid-cols-2" aria-label="List of available courses">
components/Course/CourseCard.tsx (1)

31-37: "Start Course" button implementation looks good, with a minor suggestion.

The button functionality has been implemented as suggested in the previous review. The styling is consistent, and the onClick handler correctly calls onStartCourse with the course ID.

For improved type safety, consider updating the Course interface to explicitly define id as a number:

interface Course {
  id: number;
  // ... other properties
}

This would eliminate the need for the Number() conversion in the onClick handler:

onClick={() => onStartCourse(course.id)}
components/Course/mock.ts (2)

3-43: LGTM! Consider adding JSDoc comments for better documentation.

The mockCourses constant provides a good variety of mock data that aligns well with the Course interface. The use of string IDs and varied progress values offers a realistic representation of course data.

Consider adding JSDoc comments to describe the purpose and structure of mockCourses. This can improve code readability and provide better context for other developers. For example:

/**
 * Mock data representing a list of courses.
 * Each course includes an id, title, description, progress percentage, and featured status.
 */
export const mockCourses: Course[] = [
  // ... existing code
];

46-52: LGTM! Consider adding a return type annotation for clarity.

The generateUserProgress function effectively addresses the concerns raised in the previous review. It uses course IDs, ensures consistency with the mock data, and provides a reusable solution for generating user progress.

For improved clarity and type safety, consider adding a return type annotation to the function. This can help developers understand the expected output structure at a glance. For example:

type UserProgress = {
  coursesProgress: Array<{
    courseId: string;
    progress: number;
    featured: boolean;
  }>;
};

export const generateUserProgress = (courses: Course[]): UserProgress => ({
  // ... existing code
});

32-32: LGTM! Component export is correct.

The default export of the CoursesLanding component is implemented correctly.


1-32: Verify feature flag implementation and overall great job!

The CoursesLanding component is well-implemented and aligns with the PR objectives. It uses mock data, supports responsive design, and adapts to light/dark themes. Great job on the implementation!

However, I noticed that the feature flag courses-landing mentioned in the PR objectives is not visible in this file. Let's verify its implementation:

Please ensure that the feature flag is correctly implemented and used to control the visibility of this new page.

components/Course/CourseCard.tsx (5)

1-8: LGTM! Imports and interface look good.

The Course type has been moved to a separate file, addressing a previous review comment. The onStartCourse prop type now uses number for courseId, which aligns with the mock data. These changes improve code organization and type consistency.


10-14: Component structure and styling look great!

The CourseCard component is well-structured and uses Tailwind CSS effectively. The conditional styling based on the featured property is a nice touch, and dark mode support is implemented correctly.


15-21: Course title and description rendering look good.

The course title and description are rendered using appropriate HTML tags (h2 and p respectively). The Tailwind classes used provide good styling and ensure responsiveness, including dark mode support for the description text color.


23-29: Course progress display is well-implemented.

The progress section is nicely styled using a circular badge, which aligns with the design described in the PR objectives. The use of Tailwind classes ensures consistent styling and a visually appealing display of the progress percentage.


1-42: Overall, excellent implementation of the CourseCard component!

The CourseCard component is well-structured, properly typed, and follows React best practices. It effectively uses Tailwind CSS for styling and responsiveness, including dark mode support. The implementation addresses previous review comments and aligns well with the PR objectives.

Key strengths:

  1. Clean and organized code structure
  2. Effective use of TypeScript for type safety
  3. Responsive design with dark mode support

The only minor suggestion is to update the Course interface for improved type safety of the id property.

Great job on this implementation!

components/Course/mock.ts (2)

54-54: LGTM! Excellent implementation of user progress generation.

The userProgress constant effectively uses the generateUserProgress function with mockCourses, ensuring consistency and maintainability. This approach addresses the concerns raised in the previous review and provides a robust solution for mock user progress data.


1-54: Great job on implementing the mock data for courses!

The overall structure and implementation of this file are excellent. You've effectively addressed previous review comments and created a maintainable solution for mock course and user progress data. The use of a generator function ensures consistency between mockCourses and userProgress, which is a significant improvement.

A few minor enhancements have been suggested:

  1. Adding JSDoc comments for better documentation.
  2. Including a return type annotation for the generateUserProgress function.

These small changes will further improve the code's readability and type safety. Great work on this implementation!

⚠️ Potential issue

Implement navigation logic for course start.

The handleStartCourse function is currently a placeholder. To ensure complete functionality:

  1. Implement the navigation logic to the course content page.
  2. Consider using Next.js's useRouter hook for navigation.
  3. Remove the console.log statement once the navigation is implemented.

Would you like assistance in implementing this navigation logic or creating a GitHub issue to track this task?

- Refactor the CourseCard component and update import paths to improve code organization and maintainability.

5-11: Add JSDoc comments to improve documentation

While the interface is well-structured, adding JSDoc comments would greatly improve its documentation and make it more maintainable. Consider adding a description for the interface and each property.

Here's an example of how you could improve the documentation:

/**
 * Represents a course in the system.
 */
export interface Course {
  /** Unique identifier for the course */
  id: number;
  /** Title of the course */
  title: string;
  /** Optional description of the course content */
  description?: string;
  /** Percentage of course completion (0-100) */
  progress: number;
  /** Indicates whether the course is featured */
  featured: boolean;
}

🛠️ Refactor suggestion

Consider using a more specific type for the progress property

The progress property is currently typed as number, which allows for any numeric value. However, since this likely represents a percentage, it might be beneficial to use a more specific type or add a comment to clarify the expected range.

You could consider one of these options:

  1. Use a type alias with a comment:

    /** Percentage of course completion (0-100) */
    progress: number;
  2. Or, for stricter typing, create a custom type:

    type Percentage = number & { __brand: 'percentage' };
    // ...
    progress: Percentage;

    This would require a helper function to create valid percentages:

    function createPercentage(value: number): Percentage {
      if (value < 0 || value > 100) {
        throw new Error('Percentage must be between 0 and 100');
      }
      return value as Percentage;
    }

The choice depends on the level of type safety you want to enforce in your codebase.

⚠️ Potential issue

Correct the id type and consider adding a 0% progress course

  1. The id property for each course is currently a number, but the comment on line 15 suggests it should be a string. This inconsistency should be resolved.

  2. Consider adding a course with 0% progress to cover this edge case in the mock data.

Update the mockCourses array to use string IDs and add a 0% progress course:

export const mockCourses: Course[] = [
  {
-    id: 1, // Changed to string
+    id: '1',
    title: 'Introduction to Web Development',
    description: 'Learn the basics of HTML, CSS, and JavaScript to build responsive websites.',

8-8: Consider adding prop validation for the session prop.

While the prop type is correctly defined, it's a good practice to add prop validation to ensure the component receives the expected props. Consider using PropTypes or TypeScript's built-in type checking to validate the session prop.

Example using PropTypes:

import PropTypes from 'prop-types';

// ... (component code)

Content.propTypes = {
  session: PropTypes.object
};

Or, if you're using TypeScript, you can create an interface for the props:

interface ContentProps {
  session: Session | null;
}

const Content: React.FC<ContentProps> = ({ session }) => {
  // ... (component code)
};

🛠️ Refactor suggestion

Consider adding error handling and loading state.

The component correctly renders the CoursesLanding component with the session prop. However, it might be beneficial to add error handling and a loading state for the session prop. This would improve the user experience and make the component more robust.

Here's an example of how you could implement this:

const Content = ({ session }: { session: Session | null }) => {
  const flagEnabled = isFlagEnabled(FEATURE_FLAGS.COURSES_LANDING);

  if (!flagEnabled) {
    notFound();
  }

  if (session === undefined) {
    return <div>Loading...</div>; // Or a more sophisticated loading component
  }

  if (session === null) {
    return <div>Error: Unable to load session. Please try again.</div>;
  }

  return (
    <div className="mx-auto max-w-6xl">
      <CoursesLanding session={session} />
    </div>
  );
};

This implementation handles three states: loading (session is undefined), error (session is null), and loaded (session is a valid Session object).

Enhance the UserProgress type definition

While the UserProgress type provides a good structure, consider the following improvements:

  1. Use more specific types for progress and featured:

    • progress could be constrained to a range (0-100).
    • featured could use a literal type.
  2. Consider adding optional fields that might be useful in the future, such as lastAccessedDate or completionDate.

Here's a suggested improvement:

type UserProgress = {
  coursesProgress: Array<{
    courseId: string; // Assuming this will be changed as per previous comment
    progress: number & { __brand: 'Percent' }; // Custom type to ensure 0-100 range
    featured: boolean;
    lastAccessedDate?: Date;
    completionDate?: Date;
  }>;
};

// Helper function to ensure progress is within 0-100 range
function createPercent(n: number): number & { __brand: 'Percent' } {
  if (n < 0 || n > 100) throw new Error('Progress must be between 0 and 100');
  return n as number & { __brand: 'Percent' };
}

This enhancement improves type safety and future-proofs the type definition.

⚠️ Potential issue

Refine mockCourses data structure and content

  1. Resolve the id type inconsistency:
    Change all id values to strings to match the intended type.

  2. Add a course with 0% progress:

🛠️ Refactor suggestion

Enhance generateUserProgress function for better type safety and error handling

The current implementation of generateUserProgress is good, but we can improve it:

  1. Add type assertion or validation for the progress value:
    Ensure that the progress is within the 0-100 range.

  2. Consider handling potential missing data:
    Use optional chaining or provide default values.

  3. Implement error handling:
    Throw an error if required data is missing or invalid.

Here's a suggested improvement:

export const generateUserProgress = (courses: Course[]): UserProgress => ({
  coursesProgress: courses.map((course) => {
    if (typeof course.id !== 'string') {
      throw new Error(`Invalid course id: ${course.id}`);
    }
    if (typeof course.progress !== 'number' || course.progress < 0 || course.progress > 100) {
      throw new Error(`Invalid progress for course ${course.id}: ${course.progress}`);
    }
    return {
      courseId: course.id,
      progress: course.progress,
      featured: course.featured ?? false, // Provide a default value if missing
    };
  }),
});

This implementation adds type checking, error handling, and provides default values where necessary, making the function more robust.

 * Generates mock user progress data based on the mockCourses.
 * This constant is used for development and testing purposes.
 * In a real application, this would be fetched from an API or database.
 */
export const getUserProgress = (): UserProgress => generateUserProgress(mockCourses);

// Usage example:
// const userProgress = getUserProgress();

This change adds clarity and flexibility to the code, making it easier to understand and potentially reuse in different contexts.

- Moved _client.tsx and page.tsx to components/courses/feature-flag-example.
- Updated import paths and ensured routing works under /courses.
- Aligned the structure to display the feature-flag example when visiting /courses.

5-5: Approve title change, but suggest file relocation.

The updated title "Courses Landing Page" accurately reflects the purpose of the page. However, the file location components/Course/feature-flag-example/page.tsx doesn't align with its new purpose.

Consider relocating this file to a more appropriate directory, such as app/(app)/courses/page.tsx, to match its new purpose and improve the overall project structure.


8-11: Approve function changes and suggest minor comment improvement.

The changes to the function are well-implemented:

  1. The new function name CoursesPage is more descriptive and aligns with the page's purpose.
  2. The updated comment provides clarity on why the session is being retrieved.

Consider slightly rewording the comment for even more clarity:

// Retrieve session for authentication purposes

This minor change makes the comment more direct and actionable.

components/Course/feature-flag-example/_client.tsx (3)

1-6: LGTM! Consider using more specific import for CoursesLanding.

The "use client" directive and imports are correctly implemented. However, for better clarity and maintainability, consider using a more specific import path for the CoursesLanding component.

Instead of:

import CoursesLanding from "@/components/Course";

Consider:

import CoursesLanding from "@/components/Course/CoursesLanding";

This assumes there's a specific CoursesLanding file in the Course folder. If not, please disregard this suggestion.


8-8: Consider using prop destructuring for improved readability.

The component declaration is good, but we can improve it slightly by using prop destructuring.

Instead of:

const Content = ({ session }: { session: Session | null }) => {

Consider:

const Content: React.FC<{ session: Session | null }> = ({ session }) => {

This change improves readability and follows common React patterns.


15-20: LGTM! Consider using semantic HTML for improved structure.

The rendering logic is correct, and the CoursesLanding component is used properly. The max-width class suggests good responsive design considerations.

For better semantic structure, consider using a more meaningful HTML element instead of a generic div. For example:

- <div className="mx-auto max-w-6xl">
+ <main className="mx-auto max-w-6xl">
    <CoursesLanding session={session} />
- </div>
+ </main>

Using main here would better represent that this is the main content of the page.

1-22: Overall, the implementation looks good with room for minor improvements.

The Content component is well-structured and correctly implements the feature flag logic for the courses landing page. The suggestions provided are aimed at enhancing code clarity, maintainability, and semantic structure. Great job on the implementation!


9-13: Verify the correct feature flag is being used.

The feature flag check is implemented correctly, but there's a comment suggesting that the flag might need adjustment.

Please confirm that FEATURE_FLAGS.COURSES_LANDING is the correct flag for this feature. If it needs adjustment, update it accordingly.

Also, let's verify the usage of this flag across the codebase:

This will help ensure consistency in flag usage across the application.

✅ Verification successful

Feature flag usage verified successfully.

The FEATURE_FLAGS.COURSES_LANDING flag is correctly implemented in components/Course/feature-flag-example/_client.tsx as intended.

Hello. I am trying to make a pull request but I don't seem to be allowed. This is my pull request summary:

Pull Request Summary:
Purpose:
This PR addresses the relocation of the feature-flag-example files to the appropriate /courses folder to ensure the example content is accessible when a user visits /courses.

Changes Made:
File Relocation:

Moved app/(app)/feature-flag-example/_client.tsx to components/courses/feature-flag-example/_client.tsx.
Moved app/(app)/feature-flag-example/page.tsx to components/courses/feature-flag-example/page.tsx.
These moves reflect the intended structure, making the feature-flag example available under /courses rather than as a standalone feature example.
Routing & Imports:

Updated all relevant import paths to ensure that the new location of _client.tsx and page.tsx is reflected properly across the project.
Modified the page.tsx component to ensure the Content component (from _client.tsx) is correctly referenced in the /courses route.
Purpose of the Move:

This change aligns with the intended user flow. The feature-flag-example was meant to be kept as an example under the /courses path, allowing users to view the page when visiting /courses.

This whole folder should have been left where it was an untouched. It is just to use as an example to show how to do feature flags.

This whole file shouldn't have been touched. Move your logic over to (app)/courses. Then your page will be found on /courses. The feature flag was something that could be copy and pasted as a template rather than changed.

This is perfect usage of the feature flag but just in the wrong spot.
