# @convex-dev/eslint-plugin ESLint plugin for Convex to prevent common issues and enforce best practices for files in the `convex/` directory. # Setup See [docs.convex.dev/eslint](https://docs.convex.dev/eslint). # Contributing notes Currently there is no `@convex-dev/eslint-config` package, but we could add one for ESLint 8 users to make configuration slightly easier: they could use ```js module.exports = { extends: ["@convex-dev"] }; ``` and some TypeScript parser configuration could occur here. Adding a eslint-config package only matters for ESLint 8, in ESLint 9 there's no need for a separate package. There are currently no rules that require TypeScript but these will be used in the future.
