Utils for ESLint Plugins

Utilities for working with TypeScript + ESLint together.

Note

This package has inherited its version number from the @typescript-eslint project. Meaning that even though this package is 2.x.y, you shouldn't expect 100% stability between minor version bumps. i.e. treat it as a 0.x.y package.

Feel free to use it now, and let us know what utilities you need or send us PRs with utilities you build on top of it.

Once it is stable, it will be renamed to @typescript-eslint/util for a 4.0.0 release.

Other packages similar to @typescript-eslint/experimental-utils

eslint-plugin-import

This package provides a set of ESLint rules that help validate proper imports. It is similar to @typescript-eslint/experimental-utils in that it extends ESLint's capabilities, but it focuses specifically on import/export syntax rather than providing a general set of TypeScript utilities.

eslint-utils

Similar to @typescript-eslint/experimental-utils, eslint-utils provides utility functions for working with ESLint and ASTs. However, it is not specifically tailored to TypeScript and does not provide type information utilities.

tsutils

Tsutils is a utility library that provides functions for working with TypeScript's AST and type checker. While it offers some similar functionality to @typescript-eslint/experimental-utils, it is not designed specifically for creating ESLint rules and does not integrate with ESLint out of the box.
