@backstage/eslint-plugin

A collection of ESLint rules useful to Backstage projects.

Usage

This ESLint plugin is part of the default lint configuration provided by the Backstage CLI, so you generally do not need to install it manually.

If you do wish to install this plugin manually, start by adding it as a development dependency to your project:

yarn add --dev @backstage/eslint-plugin

Then add it to your ESLint configuration:

extends: [
  'plugin:@backstage/recommended',
],

Alternatively, if you want to install in individual rules manually:

plugins: [
  '@backstage',
],
rules: {
  '@backstage/no-forbidden-package-imports': 'error',
}

The following rules are provided by this plugin:
