# @gitlab/eslint-plugin

> This package contains eslint rules developed for GitLab and shared eslint config to be used in all
> javascript projects across GitLab.

It encapsulates our coding standards and is based primarily upon
[`eslint-config-airbnb-base`](https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb-base)
and [`eslint-plugin-vue`](https://github.com/vuejs/eslint-plugin-vue) with the expectation that code
formatting is handled separately by [prettier](https://prettier.io).

Generally we should use upstream rules that are defined in `eslint` or `eslint-plugin-vue`. If one
of these packages lacks a rule, we can create it here in order to enforce it, and try to get it
upstream later.

## Eslint 9 migration

The TS portion of this plugin has been migrated to eslint v9 and can be used as `const gitlabPlugin = require('@gitlab/eslint-plugin/eslint9');`. You still add the `@gitlab/eslint-plugin` as a dependency.
