Sebastian Poxhofer 16ef1715e9 refactor(linters): add rules for @sindresorhus/is helpers (#45229)
* feat(lint): add renovate/prefer-is-helpers and renovate/prefer-is-object rules

Flag ad-hoc type checks that have @sindresorhus/is equivalents:
- .filter(Boolean) -> .filter(isTruthy)
- typeof x === 'string' -> isString(x)
- x === null || x === undefined -> isNullOrUndefined(x) (and negation)

The typeof x === 'object' shape lives in a separate suggestion-only rule
(renovate/prefer-is-object, kept at warn) because isObject()/isPlainObject()
are not drop-in equivalents: null, arrays and functions behave differently.

* refactor: fix renovate/prefer-is-helpers violations

Replace ad-hoc type checks with @sindresorhus/is helpers across lib/:
- 13x .filter(Boolean) -> .filter(isTruthy)
- 36x typeof x ==/!== 'string' -> isString(x) / !isString(x)
- 6x x === null || x === undefined -> isNullOrUndefined(x) (and negation)

Promote renovate/prefer-is-helpers to error now that the codebase is clean.
renovate/prefer-is-object stays at warn: its 15 remaining sites guard
parsed YAML/JSON or unknown values where isObject()/isPlainObject() are
not provably equivalent (null/array/function semantics).

* refactor: enforce renovate/prefer-is-object at error level

Resolve the 15 remaining warnings and raise the rule from warn to error:

- Migrate 10 sites to isObject() where the guarded value provably cannot
  be a function (parsed YAML/JSON, typed exec command arguments, or
  test-controlled fixtures): helm-values, woodpecker, bun, pre-commit
  managers, exec utils, file package cache, and the github http spec.
  In the bun manager this also fixes a latent crash where a null
  `workspaces` value would throw on the `in` operator.
- Keep 5 sites as reasoned oxlint-disable comments where excluding
  functions is load-bearing: the byte-exact fingerprint canonicalizer
  (2), the circularity walker, the zod result guard, and the generic
  hasKey helper.

Datasources

Datasources are used in Renovate primarily to fetch released versions of packages.

Follow the class-based programming style

New datasources must follow the class-based programming style. Use the java-version datasource as a reference.

Add the datasource to the API in api.ts so that the new datasource is usable. If you find Unused HTTP mocks errors in the Vitest tests and your mocked URLs are correct, make sure the datasource is correctly registered.

getReleases

The minimum exported interface for a datasource is a function called getReleases that takes a lookup config as input.

The config has:

  • packageName: the package's full name including scope if present (e.g. @foo/bar)
  • registryUrls: an array of registry URLs to try

getReleases should return an object having:

  • releases: an array of strings of matched versions. This is the only mandatory field
  • deprecationMessage: a string description of the package's deprecation notice, if applicable
  • sourceUrl: a HTTP URL pointing to the source code (for example on GitHub)
  • homepage: a HTTP URL for the package's homepage. Ideally should be empty if the homepage and sourceUrl are the same
  • changelogUrl: a URL pointing to the package's changelog (could be a Markdown file, for example). If not present then Renovate will search the sourceUrl for a changelog file
  • tags: an object mapping tag → version, for example tags: { latest: '3.0.0' }. This is only used by the followTags function

getDigest

Datasources that support digests (like Docker digests and Git commit hashes) can export a getDigest function.

The getDigest function has two inputs:

  • config: the Renovate config for the package being updated, has the same fields as getReleases
  • newValue: the version or value to retrieve the digest for

The getDigest function returns a string output representing the digest value. If no digest is found, the getDigest function should return null.
