Knip

Comparison & Migration

First of all, Knip owes a lot to the projects on this page that exist longer and they’ve all been inspirational in their own way. For best results, Knip has a vision embracing comprehensiveness which is larger in scope than any of the alternatives. So if any of those tools has the right scope for your requirements, then by all means, use what suits you best.

All tools have in common that they have less features and don’t support the concept of monorepos/workspaces. Feel free to send in projects that Knip does not handle better, Knip loves to be challenged!

Migration

A migration consists of deleting the dependency and its configuration file and getting started with Knip. You should end up with less configuration.

Comparison

depcheck

Depcheck is a tool for analyzing the dependencies in a project to see: how each dependency is used, which dependencies are useless, and which dependencies are missing from package.json.

The project has plugins (specials), yet not as many as Knip has and they’re not as advanced. It also supports compilers (parsers) for non-standard files.

The following commands are similar:

Terminal window
depcheck
knip --dependencies

unimported

Find and fix dangling files and unused dependencies in your JavaScript projects.

unimported is fast and works well. It works in what Knip calls “production mode” exclusively. If you’re fine with a little bit of configuration and don’t want or need to deal with non-production items (such as devDependencies and test files), then this might work well for you.

The following commands are similar:

Terminal window
unimported
knip --production --dependencies --files

Project status: The project is archived and recommends Knip.

ts-prune

Find unused exports in a typescript project. 🛀

ts-prune aims to find potentially unused exports in your TypeScript project with zero configuration.

The following commands are similar:

Terminal window
ts-prune
knip --include exports,types,nsExports,nsTypes

Use knip --exports to also include class and enum members.

Project status: The project is archived and recommends Knip.

ts-unused-exports

ts-unused-exports finds unused exported symbols in your Typescript project

The following commands are similar:

Terminal window
ts-unused-exports
knip --include exports,types,nsExports,nsTypes

Use knip --exports to also include class and enum members.

tsr

Remove unused code from your TypeScript Project

tsr (previously ts-remove-unused) removes unused exports, and works based on a single tsconfig.json file (includes and excludes) and requires no configuration. It removes the export keyword or the whole export declaration.
