## What it is
eslint-loader is a webpack loader that runs ESLint on JavaScript files during the webpack build process, reporting lint errors and warnings as part of bundling. It is deprecated in favor of eslint-webpack-plugin.

## Use cases
- lint javascript files during webpack builds
- fail webpack builds on eslint errors
- cache eslint results to speed up builds
- run eslint before transpiling with babel-loader
- enforce code style in a webpack pipeline

## When to choose
- maintaining a legacy webpack 3/4 project already using eslint-loader
- you cannot migrate to eslint-webpack-plugin yet

## When to avoid
- starting a new project - use eslint-webpack-plugin instead
- using webpack 5 or later
- you want actively maintained linting integration
