React homework template

This project was created with Create React App. To get acquainted and configure additional features refer to documentation.

Creating a repository by template

Use this GoIT repository as a template for creating a repository of your project. To use it just tap the «Use this template» button and choose «Create a new repository» option, as you can see on the image below.

Creating repo from a template step 1

The page for creating a new repository will open on the next step. Fill out the Name field and make sure the repository is public, then click «Create repository from template» button.

Creating repo from a template step 2

You now have a personal project repository, having a repository-template file and folder structure. After that, you can work with it as you would with any other private repository: clone it on your computer, write code, commit, and send it to GitHub.

Preparing for coding

  1. Make sure you have an LTS version of Node.js installed on your computer. Download and install if needed.
  2. Install the project's base dependencies with the npm install command.
  3. Start development mode by running the npm start command.
  4. Go to http://localhost:3000 in your browser. This page will automatically reload after saving changes to the project files.

Deploy

The production version of the project will automatically be linted, built, and deployed to GitHub Pages, in the gh-pages branch, every time the main branch is updated. For example, after a direct push or an accepted pull request. To do this, you need to edit the homepage field in the package.json file, replacing your_username and your_repo_name with your own, and submit the changes to GitHub.

"homepage": "https://your_username.github.io/your_repo_name/"

Next, you need to go to the settings of the GitHub repository (Settings > Pages) and set the distribution of the production version of files from the /root folder of the gh-pages branch, if this was not done automatically.

GitHub Pages settings

Deployment status

The deployment status of the latest commit is displayed with an icon next to its ID.

  • Yellow color - the project is being built and deployed.
  • Green color - deployment completed successfully.
  • Red color - an error occurred during linting, build or deployment.

More detailed information about the status can be viewed by clicking on the icon, and in the drop-down window, follow the link Details.

Deployment status

Live page

After some time, usually a couple of minutes, the live page can be viewed at the address specified in the edited homepage property. For example, here is a link to a live version for this repository https://goitacademy.github.io/react-homework-template.

If a blank page opens, make sure there are no errors in the Console tab related to incorrect paths to the CSS and JS files of the project (404). You most likely have the wrong value for the homepage property in the package.json file.

Routing

If your application uses the react-router-dom library for routing, you must additionally configure the <BrowserRouter> component by passing the exact name of your repository in the basename prop. Slashes at the beginning and end of the line are required.

<BrowserRouter basename="/your_repo_name/">
  <App />
</BrowserRouter>

How it works

How it works

  1. After each push to the main branch of the GitHub repository, a special script (GitHub Action) is launched from the .github/workflows/deploy.yml file.
  2. All repository files are copied to the server, where the project is initialized and linted and built before deployment.
  3. If all steps are successful, the built production version of the project files is sent to the gh-pages branch. Otherwise, the script execution log will indicate what the problem is.
