Comparison & Migration

First of all, Knip owes a lot to the projects on this page. Each and every one of them has been inspirational in their own way. The scope of Knip is larger than all of them combined, which is a vision you might not align with. 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, I’m up for the challenge!

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 I’d argue they’re not as advanced. It also supports compilers (parsers) for non-standard files.

The following commands are similar:

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 stuff (such as devDependencies and test files), then this might work well for you.

The following commands are similar:

unimported
knip --production --dependencies --include files

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 project is in maintenance mode, while it recommends Knip.

The following commands are similar:

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

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

ts-unused-exports

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

The following commands are similar:

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

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