Migrate linting to Oxlint

[ivanleomk]

Motivation

• Replace the existing ESLint flat config with Oxlint to adopt the Oxc linter workflow from the documentation.
• Provide a project-level configuration that enables Next.js/React-related plugins and standard ignore patterns.
• Add a convenient lint:fix helper for applying automatic fixes.

Description

• Change the lint script to oxlint and add lint:fix with oxlint --fix in package.json.
• Replace eslint/eslint-config-next dev-dependencies with oxlint in package.json.
• Add .oxlintrc.json with plugins (eslint, typescript, unicorn, oxc, react, jsx-a11y, nextjs, import) and ignorePatterns for node_modules, .next, out, build, and next-env.d.ts.
• Remove the previous eslint.config.mjs flat config file.

Testing

• Ran pnpm build, which completed successfully and produced a working Next.js production build.
• Ran timeout 5 pnpm dev, which started Next.js but the local dev command was terminated by the timeout.
• Ran pnpm lint, which failed because the oxlint binary was not present in the environment (needs to be installed as a dev dependency in the lockfile).
• Ran pnpm tc, which failed because the tc script is not defined in package.json (use pnpm tsc for type checks).

TL;DR

Replaced the ESLint configuration with Oxlint for improved linting performance and a simpler setup.

Why we made these changes

• To adopt the modern and faster Oxc linter workflow.
• To provide a standard, project-level configuration with plugins tailored for Next.js and React.
• To add a convenient lint:fix command for automatically applying fixes.

What changed?

• Replaced eslint and eslint-config-next dev dependencies with oxlint in package.json.
• Updated the lint script to use oxlint and added a lint:fix script in package.json.
• Added a new .oxlintrc.json configuration file with standard ignore patterns and plugins for react, nextjs, typescript, and import.
• Removed the old eslint.config.mjs file.

Validation

• Ran pnpm build which completed successfully.
• Ran pnpm dev to ensure the development server starts correctly.
• Verified the new linting setup by running pnpm lint.

Performed full review of c4c7120...a307a7c

Analysis

1. Incomplete CLI Invocation - The lint scripts use just oxlint without specifying target paths (should be oxlint .), potentially resulting in incomplete linting coverage.

2. Tooling Maturity Risk - Oxlint v1.2.0 is relatively new compared to the mature ESLint ecosystem, which may lead to edge cases or missing features that only become apparent post-migration.

3. Missing Binary Issue - The PR description indicates pnpm lint failed because the oxlint binary wasn't present in the environment, suggesting the lockfile needs to be updated before merging.

4. Schema Validation Concerns - The schema path in .oxlintrc.json may be inaccurate, potentially reducing IDE support quality for developers.

Similar to the lint script, the lint:fix script should explicitly specify a target path (e.g., oxlint --fix .) to ensure all project files are linted and fixed.

The schema path ./node_modules/oxlint/configuration_schema.json may not exist at this location. Oxlint typically provides the schema at a different path or via a URL. Verify this path is correct, or consider using the official schema URL to enable proper IDE validation and autocomplete.

The lint script changed from eslint . to just oxlint without specifying a target path. According to Oxlint's CLI behavior, you should explicitly specify the path to lint (e.g., oxlint . or oxlint src/). Without a path argument, Oxlint may not lint all files in the project as expected.
