Request new plugins here

[webpro]

Please add one comment per plugin (please link to website/repo/docs), which others can then upvote using reactions like 👍 (not more comments).

The idea is that you can request/upvote plugins here. Contributors/me can implement them.

Please make sure the plugin isn't already available/listed on https://knip.dev/reference/plugins

Ladle (#268)

[webpro]

Vike (#275)

[birtles]

React cosmos

Includes:

• Fixtures (docs, e.g.)
• Decorators (docs, e.g.)
• Plugins (docs, e.g.)

/cc @ovidiuch

[Faithfinder]

NestJS, maybe?

It's very class based, so it would be focused on classMembers rules.

It would need to detect usage of class members by decorators, basically - e.g, something decorated with @ResolveField is used.

[webpro]

WebdriverIO (#464)

[justingrant]

Not sure if this is a plugin or core, but support for .mdx files. (used by Storybook and other docs generators)

[webpro]

@justingrant Please file a separate issue for this (as it's not a plugin).

[netner-d]

Serverless framework (1 183 585 downloads a week). It uses serverless.yml files for config and includes :

• Plugins (docs/eg)
• Serverless function definitions, so entries (docs/eg, under functions.*.handler field)

[webpro]

Please don't dump words here. It'll be a lot more convincing if you'd be more precise and provide one or two links to the library and/or configuration pages to avoid any ambiguity.

Yeah, absolutely sorry about that, I thought it was the method to collect people opinion as I saw similar comments above... I'm rectifying

tsd (#535)

[DaniFoldi]

wrangler
ideas: find wrangler.toml/json and set main as entrypoint, and exclude from unused dependencies

[webpro]

Just saying, for anyone interested, it's now more fun and easier than ever to write a plugin: https://knip.dev/guides/writing-a-plugin

[guy-borderless]

is deno compat a plugin? If so, what would it take? Deno uses the web standard import_map.json

[sifferhans]

Would it be possible to create a Nuxt plugin? Nuxt heavily uses auto-imports, so I imagine it could be harder to trace down what is being used.

[auvred]

Docusaurus - https://docusaurus.io/

[webpro]

Ionic (#604)

[bbeesley]

I was gonna request xo, but I've just opened a PR for it instead since I was interested in how they work.
#621

[webpro]

Plugins added recently:

• Wrangler - thanks @DaniFoldi!
• xo - thanks @bbeesley!
• improved Ionic/Capacitor - thanks @ptmkenny!

[emmanuelchucks]

Expo (expo.dev)

[tmm]

size-limit (and related packages @size-limit/*)

[webpro]

For everyone interested in support for Expo, please see #126. Looking for feedback!

lockfile linting

lint lockfiles for improved security and trust policies

https://github.com/lirantal/lockfile-lint
https://github.com/lirantal/lockfile-lint/blob/main/packages/lockfile-lint/README.md

[birtles]

Can be tested with npm i -D https://pkg.pr.new/knip@2de3924 (or any package manager). Would be very useful if you could try it out to increase coverage and improve the plugins.

Works great for me. Thank you!

[silverwind]

Makefile:

lint:
	npx eslint

Should mark eslint as used. I would say this should be core functionality, e.g not a plugin.

[BMFreed]

@webpro I know this was already requested, but are there plans to add a Nuxt plugin?

[webpro]

Re. Nuxt plugin: Usually "auto-imports" might be hard to track indeed during static or even dynamic analysis.

In general not doing much of new features myself at the moment. Sponsored might be an option (DM me). Open to pull requests!

preconstruct allows multiple entrypoints to be defined in a package's package.json file. Standalone entrypoints currently have to be manually defined using entry.

[webpro]

VitePress (Site Config)

[webpro]

Karma (Configuration File)

[webpro]

Added a few plugins in v5.28.0:

• Nest
• Nuxt
• Preconstruct
• Vike

NOTE: the Nuxt plugin has no support for auto-import magic, except for defineNuxtConfig (to prevent insta-throw/offs). Should probably add a warning on the plugin page.

[flip-it]

package.json:

{
  …
  "dependencies": {
    …
    "@company/browserslist-config": "2.0.0",
  },
  "browserslist": [
    "extends @company/browserslist-config"
  ],
  …
}

should not throw Unused dependencies for @company/browserslist-config

[Faithfinder]

Panda CSS (I think just the config file?)
PostCSS, should be included with Vite plugin

[RafalFilipek]

tsx.

Currently

// ./bin/index.ts

#!/usr/bin/env tsx

const x: string = 'Hello knip';

is not detected.

// ./package.json

{
  "bin": {
    "app": "./bin/index.ts"
  },

  "dependencies": {
    "tsx": "4.7.1",
  },

}

[webpro]

Does #!/usr/bin/env tsx point to the tsx dependency executable (in the project's node_modules)? Please file a separate bug report if you think Knip should handle this better as this is rather core area (not so much plugin-specific).

Flow

Getting some false positives for type exports. unimported used to have an option to remove flow types and I wonder if that's needed or I need to add any additional configuration to detect unused flow types?

Thanks!

[bigpopakap]

Prisma ORM

Maybe this specific issue isn't in scope for a Prisma plugin, but my prisma/seed.ts file is getting flagged but is used in a package.json script:

"prisma": {
    "seed": "ts-node --compiler-options {\"module\":\"CommonJS\"} prisma/seed.ts"
  },

[mattfysh]

Pulumi

You might scan for **/Pulumi.yaml and create a new entry per pulumi stack program.

[webpro]

Friendly reminder to everyone that it's cool to implement plugins and submit pull requests ❤️

React Router v7 — getting false positives after upgrading from Remix

I created temperary solution for react router 7 before a plugin is created:

import type { RouteConfigEntry } from "@react-router/dev/routes";
import { KnipConfig } from "knip";
import path from "path";
import { fileURLToPath } from "url";

const __filename = fileURLToPath(import.meta.url); // get the resolved path to the file
const __dirname = path.dirname(__filename); // get the name of the directory
const appDir = __dirname + "/app";
globalThis.__reactRouterAppDirectory = appDir;
const routes = await import("./app/routes");

const routeConfig = await routes.default;

const mapRoute = (route: RouteConfigEntry): string[] => {
   return [`app/${route.file}`, ...(route.children ? route.children.flatMap(mapRoute) : [])];
};
const routeEntryFiles = routeConfig.flatMap(mapRoute);
export default {
   entry: [
      ...routeEntryFiles,
      "public/sw.js",
      "server.mjs",
      "app/root.tsx",
      "app/entry.client.tsx",
      "app/entry.server.tsx",
      "react-router.config.ts",
   ],
} satisfies KnipConfig;

[s7dhansh]

MeteorJS.
It imports files as absolute import by default. eg. /src/main instead of src/main. Hence the result from knip is completely inaccurate. May be there is a config option to do that, but as of now I have not been able to find it.

Thanks.

[superfaz]

SASS/SCSS.
It can import dependencies via @use or @import.

Thanks.
