Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

This upgrade from ESLint v8 to v10 is a major transition with significant breaking changes, requiring a complete overhaul of your configuration.

Key Breaking Changes:

• Mandatory Configuration Migration: The legacy configuration system using .eslintrc.* files is completely removed in v10.0.0. You must migrate your entire configuration to the new "flat config" format (eslint.config.js), which was introduced as the default in v9. This is a substantial change requiring a full rewrite of your ESLint setup.

• Node.js Version Requirement: Support for older Node.js versions has been dropped. ESLint v10.0.0 requires Node.js v20.19.0 or newer. The upgrade to v9 had already required Node.js v18.18.0+.

• Removed Rules and Formatters: The require-jsdoc and valid-jsdoc rules were removed in v9. Additionally, several formatters (including checkstyle, junit, compact) were removed, with only stylish, html, json, and json-with-meta remaining.

• Configuration Discovery Change: v10 introduces a new configuration file lookup algorithm that searches for eslint.config.js starting from the directory of each linted file, which primarily affects monorepo setups.

Sources:

• ESLint v10 Migration Guide
• ESLint v9 Migration Guide

Recommendation: This is a high-effort upgrade that cannot be completed without significant manual intervention. Developers must rewrite the project's ESLint configuration from the legacy .eslintrc format to the new eslint.config.js flat config format before this upgrade can be merged.
