eslint-import-resolver-webpack

What is eslint-import-resolver-webpack?

The eslint-import-resolver-webpack package is an ESLint plugin that allows you to use Webpack's module resolution in your ESLint configuration. This is particularly useful for projects that use Webpack aliases or custom module resolution paths, ensuring that ESLint can correctly resolve and lint your imports.

What are eslint-import-resolver-webpack's main functionalities?

Webpack Configuration Integration

This feature allows you to specify a Webpack configuration file in your ESLint settings. ESLint will use this configuration to resolve modules, ensuring that your import statements are correctly validated.

{"settings":{"import/resolver":{"webpack":{"config":"webpack.config.js"}}}}

Custom Webpack Configuration

You can also provide a custom Webpack configuration directly within the ESLint settings. This is useful if you have a simple configuration or want to override specific settings for ESLint.

{"settings":{"import/resolver":{"webpack":{"config":{"resolve":{"alias":{"@components":"./src/components"}}}}}}}

Multiple Webpack Configurations

This feature allows you to specify multiple Webpack configuration files. ESLint will try to resolve modules using each configuration in the order they are provided.

{"settings":{"import/resolver":{"webpack":{"config":["webpack.config.dev.js","webpack.config.prod.js"]}}}}

Other packages similar to eslint-import-resolver-webpack

eslint-import-resolver-alias

The eslint-import-resolver-alias package allows you to define custom path aliases for module resolution in ESLint. Unlike eslint-import-resolver-webpack, it does not rely on a Webpack configuration file but instead uses a simpler alias configuration directly in the ESLint settings.

eslint-import-resolver-node

The eslint-import-resolver-node package is a simple resolver for Node.js-style module resolution. It does not support Webpack-specific features like aliases or custom module resolution paths, making it less flexible than eslint-import-resolver-webpack for projects that use Webpack.

eslint-import-resolver-typescript

The eslint-import-resolver-typescript package is designed for projects using TypeScript. It allows ESLint to resolve modules based on the TypeScript configuration file (tsconfig.json). This package is more suitable for TypeScript projects compared to eslint-import-resolver-webpack, which is more general-purpose.

README

eslint-import-resolver-webpack

Webpack-literate module resolution plugin for eslint-plugin-import.

Published separately to allow pegging to a specific version in case of breaking changes.

To use with eslint-plugin-import, run:

npm i eslint-import-resolver-webpack -g

or if you manage ESLint as a dev dependency:

# inside your project's working tree
npm install eslint-import-resolver-webpack --save-dev

Will look for webpack.config.js as a sibling of the first ancestral package.json, or a config parameter may be provided with another filename/path either relative to the package.json, or a complete, absolute path.

If multiple webpack configurations are found the first configuration containing a resolve section will be used. Optionally, the config-index (zero-based) setting can be used to select a specific configuration.

---
settings:
  import/resolver: webpack  # take all defaults

or with explicit config file name:

---
settings:
  import/resolver:
    webpack:
      config: 'webpack.dev.config.js'

or with explicit config file name:

---
settings:
  import/resolver:
    webpack:
      config: 'webpack.multiple.config.js'
      config-index: 1   # take the config at index 1

or with explicit config object:

---
settings:
  import/resolver:
    webpack:
      config:
        resolve:
          extensions:
            - .js
            - .jsx

If your config relies on environment variables, they can be specified using the env parameter. If your config is a function, it will be invoked with the value assigned to env:

---
settings:
  import/resolver:
    webpack:
      config: 'webpack.config.js'
      env:
        NODE_ENV: 'local'
        production: true
