feat(examples-plugins): add knip to example plugin #570

BioPhoton · 2024-03-15T21:15:12Z

This PR is just here to showcase knip implementation and screenshots.

This PR includes:

examples-plugins/src
- logic to wrap the knip CLI
- unit and integration tests
- docs
utils
- helper to setup categories capital and singular

This PR does not include:

e2e tests because it is an example

See the portal here: https://staging.code-pushup.dev/portal/code-pushup/cli-utils/commit/985ac7155f1f8cb8ad1b482a984740ad3d2d5e75/dashboard

Changes for a followup PR:

issues table - duplicated exports should list last reference instead of first
issues table - unused dependencies should link to line where package sit's
issues table - unlisted dependencies, unused development dependencies could list only one referencing file (otherwise we see multiple times the same issue title with a difference source but installing it ones fixes the issues)
issues table - issue messages could include the full audit title e.g. "Unused export docsUrlSchema" instead of "Export docsUrlSchema"

Example Audit Interpretation

Legend:

✅ - valid result
❌ - false positive
❓ - open question
⏳ - evaluation pending

Unused files (1)

✅ packages/plugin-lighthouse/src/index.ts
Can be fixed by using it in e.g. e2e tests

Unused dependencies (1)

✅ cli-table3 package.json
Can be fixed by uninstalling cli-table3
Run npm remove cli-table3 to remove dependency

Unused devDependencies (8)

✅ tsx package.json
This package is not used anywhere in the code either directly on in "scripts" or configuration files.
You can fix it by running npm remove tsx
Same goes for the follwing dependencies
✅ @trivago/prettier-plugin-sort-imports package.json
⏳ eslint-plugin-jsx-a11y package.json
❓ eslint-plugin-react package.json
should have been picked up by the nx helper WDYT @beaussan
the following packages are (most probably) a cascade of this issue
❓ eslint-plugin-react-hooks package.json
❓ jsonc package.json
❌ commitlint-plugin-tense package.json
false as it is used in commitlint.config.js

/** @type {import('@commitlint/types').UserConfig} */
const configuration = {
  extends: ['@commitlint/config-conventional'],
  plugins: ['commitlint-plugin-tense'],
// ...
}

❌ conventional-changelog-angular package.json
false as a peer dependency of commit. (cascade of commitlint-plugin-tense)
Run npm ls conventional-changelog-angular to list check dependent packages.

├─┬ @commitlint/cli@17.8.1
│ └─┬ @commitlint/lint@17.8.1
│   └─┬ @commitlint/parse@17.8.1
│     └── conventional-changelog-angular@6.0.0
└─┬ commitlint-plugin-tense@1.0.2
  └─┬ @commitlint/lint@19.1.0
    └─┬ @commitlint/parse@19.0.3
      └── conventional-changelog-angular@7.0.0

Unlisted dependencies (38)

✅ jsonc-eslint-parser .eslintrc.json
This is a peer dependency of @nx/eslint-plugin, but and not directly installed.
If you uninstall @nx/eslint-plugin you don't have jsonc-eslint-parser anymore available.
Run npm ls jsonc-eslint-parser to list the root package:

@code-pushup/cli-source@0.29.0 /Users/michael_hladky/WebstormProjects/quality-metrics-cli
└─┬ @nx/eslint-plugin@17.3.2
  └── jsonc-eslint-parser@2.4.0

To fix it run npm i jsonc-eslint-parser --save-dev
same is valid for all following issues of jsonc-eslint-parser

✅ jsonc-eslint-parser e2e/cli-e2e/.eslintrc.json
✅ jsonc-eslint-parser packages/cli/.eslintrc.json
✅ jsonc-eslint-parser packages/core/.eslintrc.json
✅ jsonc-eslint-parser packages/models/.eslintrc.json
✅ jsonc-eslint-parser packages/nx-plugin/.eslintrc.json

✅ jsonc-eslint-parser packages/plugin-js-packages/.eslintrc.json
✅ jsonc-eslint-parser packages/plugin-lighthouse/.eslintrc.json
✅ jsonc-eslint-parser packages/utils/.eslintrc.json
✅ jsonc-eslint-parser testing/test-setup/.eslintrc.json
✅ jsonc-eslint-parser testing/test-utils/.eslintrc.json
✅ minimatch tools/eslint-to-code-pushup.mjs
This is used in tools/eslint-to-code-pushup.mjs, but and not listed in package.json. The code works because other packages like @nx/devkit have minimatch as peer dependency. If you would remove all related packages like @nx/devkit, tools/eslint-to-code-pushup.mjswould stop working.
Run npm ls minimatch to list the root package:

├─┬ @nx/devkit@17.3.2
│ └─┬ ejs@3.1.9
│   └─┬ jake@10.8.7
│     ├─┬ filelist@1.0.4
│     │ └── minimatch@5.1.6
│     └── minimatch@3.1.2

To fix it run npm i minimatch --save-dev
same is valid for issues of tslib

✅ tslib tsconfig.base.json
✅ @example/custom-plugin testing/test-utils/src/lib/fixtures/configs/code-pushup.needs-tsconfig.config.ts
This is used as dummy reference in a test like this.

  // the point is to test runtime import which relies on alias defined in tsconfig.json "paths"
// non-type import from '@example/custom-plugin' wouldn't work without --tsconfig
import customPlugin from '@example/custom-plugin';

const config = {
  plugins: [customPlugin],
};

export default config;

It can be fixed by adding the package name to the knip.config.ts

 export default { 
// ...
  ignoreDependencies: [
      // 👇 fixed by add package name to ignoreDependencies here
      '@example/custom-plugin'
    ],
}

✅ @commitlint/types commitlint.config.js
Is used in like this: const { RuleConfigSeverity } = require('@commitlint/types');.
To fix it run npm i @commitlint/types --save-dev
❓ basic e2e/cli-e2e/vite.config.e2e.ts
This shows no dependents when running npm ls basic
This could be fixed by installing basic manually over npm i basic -D but seems odd as there are no deps listed.
Same goes for all other issues related to basic

The Unused development dependencies audit is full of false positives, I'm afraid 😞 It doesn't seem to detect usage other than import/require in code. Other than the false positives already mentioned, the following are also not valid:

✅ tsx package.json
This package is not used anywhere in the code either directly on in "scripts" or configuration files.
You can fix it by running npm remove tsx
Same goes for the follwing dependencies
✅ @trivago/prettier-plugin-sort-imports package.json

@trivago/prettier-plugin-sort-imports is used, Prettier picks it up automatically, importOrder and importOrderSortSpecifiers options configured in .prettierrc
- could also be made explicit by adding plugins: ['@trivago/prettier-plugin-sort-imports']
tsx is used by the perf Nx target in packages/utils/project.json

True! found out prettier was excluded in the config

tsx is used by the perf Nx target in packages/utils/project.json

True. figured out perf folder is configured wrong

beaussan · 2024-04-07T11:31:59Z

❓ eslint-plugin-react package.json
should have been picked up by the nx helper WDYT @beaussan
the following packages are (most probably) a cascade of this issue
❓ eslint-plugin-react-hooks package.json

This was the case since we excluded the example projects, I changed that in the base config and this is now properly reported

❌ commitlint-plugin-tense package.json
false as it is used in commitlint.config.js

This is something missing on the knip side, it will only look at the extends but not the plugins array. I will make a follow up on their side to update it. In the meantime, added to the ignore array

❓ basic e2e/cli-e2e/vite.config.e2e.ts
This shows no dependents when running npm ls basic
This could be fixed by installing basic manually over npm i basic -D but seems odd as there are no deps listed.
Same goes for all other issues related to basic

This is a false positive, it shouldn't require a npm lib since it's a built in of vitest. I will make a pr to add it to the built in reporters on the knip side so this shouldn't occur anymore. In the meantime, I added it to the ignore dependencies array

tsx is used by the perf Nx target in packages/utils/project.json

This should have been picked up by knip, since it will look at the project json configs to detect the scripts and thrid party requirements, I will follow up with an issue on their side
