oxlint-rules-gacha

An unofficial fan site for learning the 870 oxlint rules, one draw at a time.

https://oxlint-gacha.newt239.dev

Each draw takes you to that rule's page, and the URL is the thing you share. Drawn rules pile up in a collection you can take home as an .oxlintrc.json snippet. Rule descriptions and code samples are shown verbatim from the oxc project (MIT).

Setup

npm ci
npm run rules:build   # fetch rule data from oxc.rs
npm run dev

Node.js 22.12.0 or later. Use npm; other package managers are not supported.

See .env.example for the environment variables. NEXT_PUBLIC_* values are inlined at build time, so set them on the host before the build runs. Analytics stays off unless NEXT_PUBLIC_GA_ID is set, never sends hits from localhost, and stores nothing in cookies until the visitor accepts the consent banner. See /privacy for what is collected. Without NEXT_PUBLIC_GA_ID there is nothing to consent to, so the banner and the consent controls on /privacy are not rendered — set the variable in .env.local to work on them.
