The ESLint plugin integrates ESLint with Nx. It allows you to run ESLint through Nx with caching enabled. It also includes code generators to help you set up ESLint in your workspace.
Setting Up @nx/eslint
Installation
Keep Nx Package Versions In SyncMake sure to install the @nx/eslint version that matches the version of nx in your repository. If the version numbers get out of sync, you can encounter some difficult to debug errors. You can fix Nx version mismatches with this recipe.
In any Nx workspace, you can install @nx/eslint by running the following command:
❯
nx add @nx/eslint
This will install the correct version of @nx/eslint.
How @nx/eslint Infers Tasks
The @nx/eslint plugin will create a task for any project that has an ESLint configuration file present. Any of the following files will be recognized as an ESLint configuration file:
.eslintrc.eslintrc.js.eslintrc.cjs.eslintrc.yaml.eslintrc.yml.eslintrc.jsoneslint.config.js
Because ESLint applies configuration files to all subdirectories, the @nx/eslint plugin will also infer tasks for projects in subdirectories. So, if there is an ESLint configuration file in the root of the repository, every project will have an inferred ESLint task.
View Inferred Tasks
To view inferred tasks for a project, open the project details view in Nx Console or run nx show project my-project --web in the command line.
@nx/eslint Configuration
The @nx/eslint/plugin is configured in the plugins array in nx.json.
