`knip` is the best code maintenance tool I've used in my 20 years of development, just an absolute work of art

knip is great.

A great example of stuff just working. It detects your environment so well and its defaults are almost too good because I didn’t realise it was doing everything automatically.

Then was like “this is how tooling should be, this has taken me an hour not a day and it’s faster and more accurate and more future proof”

Five stars ⭐️⭐️⭐️⭐️⭐️

Crazy useful tool. Thought it would be a nightmare to setup in my Next.js+Workers repo but it has crazy good automatic detection for code dependencies. In short, Knip creates a graph of code use and highlights dead code for you to snip (knip).

Lars is singlehandedly building the best tool to keep your code clean and your dependencies minimal. And he's so engaging and helpful. Can't imagine going back to not using knip 👏

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. undefined

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! 👏 undefined

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.

Just tried this on https://github.com/getsentry/sentry/ - got some super useful results! Nice work.

I've manage to delete 6k LOC in the last 30 minutes 🫣

Great job here @webprolific 👍🏽

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

Recommend 💯

Here's how Josh used it to remove code bloat in Centered:

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. 👀

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

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. ✂️
