Debug your rules

A fantastic tool called eslint-flat-config-viewer can show all your applied rules, display links to the documentation, and group rules by the provider. I recommend using it to dig deeper into your project's rules.

Goal

The purpose of this package is to develop confidently without pressure from tools and too strict rules, but at the same time, try to make sure that tools help you not to shoot in your foot.

Some key points behind this package include:

• developer should not be blocked by the tool and should be able to use language features,
• no or minimum warnings, without compromises, just errors that don't mess up output,
• minimum formatting rules or none, this should be handled by formatter without blocking your flow,
• no configuration, plug the rules and start working; otherwise, override in your config,
• batteries included by default: typescript, prettier, react, nextjs, tailwind, vitest, playwright, storybook
• rules should not force you to use a specific programming style but help you catch bugs

Rules

• Recommended rules from @eslint/js,
• strict-type-checked and stylistic-type-checked rules from @typescript-eslint/eslint-plugin
• Additional stylistic rules from @typescript-eslint/eslint-plugin
• Recommended rules from eslint-plugin-sonarjs
• Carefully hand-picked rules from eslint-plugin-unicorn
• Recommended rules from eslint-plugin-jsx-a11y and eslint-plugin-react-hooks
• Carefully hand-picked rules from eslint-plugin-react
• Single rule for lodash imports
• Recommended and core-web-vitals configs from @next/eslint-plugin-next
• Recommended rules from eslint-plugin-playwright
• Recommended rules from eslint-plugin-vitest
• Recommended rules from eslint-config-prettier that turn off rules which overlap with @typescript-eslint and prettier

Inspirations and alternatives

• Sheriff -- Great set of rules, but with some style restrictions
• Antfu config -- Another great set of rules
• XO -- Flat version of popular set xo, still in beta, includes some restrictive rules that I don't always agree with
