🧡 Testimonials
Quinn Slack@sqs
warning: do not use a tool like https://knip.dev + code search to delete a ton of unused code. It works too well.
I just did this in https://github.com/sourcegraph/cody/pull/2705, and my boss said if I end the week with net negative lines of code committed, I'm in deep trouble.
Greg Bergé@gregberge_
Ran http://knip.dev in @argos_ci, and boom 💥! Dead code detected instantly. With a good config, it can run on CI to keep projects clean. Installing this tool should be a no-brainer, like Prettier or ESLint.
Kudos, @webprolific! 👏

Problem:
🚫 Your project has unused files.
🚫 It has unused npm dependencies.
🚫 It has unused TypeScript exports.
But you haven't noticed, because these things are hard to spot.
Solution: knip
I just used knip to find and resolve dozens of issues.

Gajus@kuizinas
Big fans of Knip at @Contra. Such an extremely well developed and maintained project
Abhijeet Prasad@imabhiprasad
Just tried this on https://github.com/getsentry/sentry/ - got some super useful results! Nice work.
Fernando@fernandoeeu_dev
I've manage to delete 6k LOC in the last 30 minutes 🫣
Great job here @webprolific 👍🏽
Dominik 🔮@TkDodo
knip is an amazing tool. Shoutout to @webprolific for building it 🙌.
Not cleaning up correctly has a real maintenance cost. I've deleted lots of dead code - functions that were only used in tests and components that were only used in stories - all thanks to knip 🚀.

🛠️ Knip
👉🏻 Knip finds unused files, dependencies and exports in your JavaScript and TypeScript projects.
👉🏻 Less code and dependencies lead to improved performance, less maintenance and easier refactorings.

Knip is wonderful at finding out unused code/dependencies in a legacy JavaScript/TypeScript application

Here's how Josh used it to remove code bloat in Centered:
Smashing Magazine 🇺🇦 🏳️🌈@smashingmag
Unused files, exports, and dependencies often clutter projects, as it’s difficult knowing when one thing relies on another and scary to remove something you’re not sure is in use. 👀
↬ Meet Knip, which scours projects for these unused artifacts: https://www.smashingmagazine.com/2023/08/knip-automated-tool-find-unused-files-exports-dependencies/
Dan Vanderkam@danvdk
Recommendation update: use knip to find dead code, types and dependencies in your @typescript ✂️https://effectivetypescript.com/2023/07/29/knip/

Streamlining React projects with Knip:
Recently, I employed Knip for a project, and it worked wonders!
It efficiently resolved issues with removing
✅ Unused files,
✅ Unused npm dependencies,
✅ Unneeded TypeScript exports.
A real time-saver for maintaining a clean and efficient codebase. 🛠️ #ReactDevelopment

Waldek Mastykarz@waldekm
Found a bunch of unused code, -dependencies, and unnecessary exports. Had just one false positive but overall pretty good. 10/10 would recommend.
If you’ve got a JavaScript package/project use Knip and remove unnecessary code. ✂️
