eslint-config-conventions
ESLint shareable config to enforce strict conventions and good code quality.
📜 About
eslint-config-conventions is a ESLint configuration to enforce strict conventions and good code quality, it is highly inspired from eslint-config-standard-with-typescript but it is stricter and with no formatting rules, only code-quality rules. It supports both JavaScript and TypeScript.
This configuration is mostly for catching bugs and code-quality so it is recommended to use it with Prettier for a consistent code style, it works with any .prettierrc.json
configuration.
More information about formatting rules vs code-quality rules can be found on Prettier vs. Linters.
