chore(lint): check Svelte components with svelte-policy

[chhoumann]

Summary

QuickAdd's Svelte policy checker and oxlint plugin now come from the shared svelte-policy package, instead of the copy in tooling/ that #2224 added. PodNotes uses the same package, so each rule now has one implementation to fix. The rules QuickAdd enforces are unchanged, and every message is byte-identical to master's.

The package also closes gaps in the old checker. QuickAdd's current code triggers none of them:

• svelte-ignore comments. These were reported wrongly or skipped:
  • dashed, comma-separated or next-line codes;
  • comments in legacy components;
  • empty comments, which now count as unused;
  • script // svelte-ignore comments, which are now checked;
  • codes, which are now matched per compile mode the way Svelte matches them.
• Object literals in mixed attribute values. Objects inside attribute values that mix text and mustaches are reported again, as svelte/no-object-in-text-mustaches did.
• Each blocks without an item no longer need a key.
• no-not-function-handler is back, covering handlers in JavaScript and no-script components too.
• Backtick member names such as window[`setTimeout`] no longer bypass the timer and DOM rules.

The package is svelte-policy 0.1.0 on npm, installed as "svelte-policy": "^0.1.0".

Changes

• svelte-policy.json holds QuickAdd's config: the ten Obsidian selectors and their messages, runes-only and no-svelte-store on, and the logger message for no-console.

• lint:svelte runs svelte-policy. .oxlintrc.syntax.json loads svelte-policy/oxlint under the quickadd name and maps each rule one to one, keeping its globs and severities:

  Before	After
  quickadd/svelte-internal on **/*.ts	quickadd/no-svelte-internal
  quickadd/svelte-runes on **/*.svelte.ts	quickadd/no-svelte-store and quickadd/runes-only
  quickadd/svelte-debug (warn)	quickadd/no-inspect (warn)
  quickadd/restricted-syntax	unchanged

• Rule ids that change. Three component diagnostics that reported restricted-syntax now have their own ids: no-svelte-store (svelte/store imports), no-svelte-internal (svelte/internal imports) and runes-only (named createEventDispatcher imports). In .svelte.ts files, runes-only also reports $: statements. No file has one.

• Deleted tooling/svelte-policy.mjs and tooling/oxlint-plugin.mjs, including the svelteImportGuards leftover, and removed the esquery dev dependency.

• tests/tooling/sveltePolicy.test.ts keeps the tests of QuickAdd's own wiring:

  • oxlint against .oxlintrc.syntax.json, now with a dispatcher fixture and a severity check on no-inspect;
  • the type-aware test;
  • message equality between oxlint and the checker;
  • checks of svelte-policy.json.

  The fixture corpus moved to the package, where every build(deps): adopt native tooling and replace ESLint #2224 fixture is kept verbatim.

• tooling/README.md points to the package and updates the rule-audit rows.

• Out of scope: the check script, tests/tooling/svelteCheck.test.ts and all svelte-check wiring are unchanged.

Testing / validation

All on Node 22.23.2 and pnpm 10.32.1, on the merge with origin/master ca6ea85 (#2226, #2227, #2228):

• pnpm install --frozen-lockfile succeeds with node_modules deleted first. pnpm-lock.yaml differs from master only by the svelte-policy@0.1.0 registry entry and its importer line, with the same integrity as the published tarball, plus the removed direct esquery entry.

• pnpm run lint:svelte reports Svelte policies: 0 errors, 0 warnings.

• pnpm run test: 501 files passed and 6 skipped, with 6,880 tests passed and 28 skipped.

• pnpm run build-with-lint passes. Its parallel lint ran lint:native, lint:svelte (0 errors, 0 warnings), lint:tsconfig and check (58 files, 0 errors, 0 warnings).

• main.js and styles.css are byte-identical to master's build at ca6ea85. main.js sha256 is d83aa6eeaa77bbcfe0e3574f3ab1e67c57469506074c43f5e67087bf64ae6127.

• Comparison at d57eb15: master's checker and the package, run side by side with QuickAdd's config, agreed on all 202 sources (every fixture in master's test file plus all 57 components). Line, column, message and severity matched, and the rule matched after the three renames.

• Planted violations print master's messages on this branch:

  • a svelte/internal import in a .ts file;
  • a createEventDispatcher import in a .svelte.ts file;
  • console.log and document.createElement("div") in a template.

  After the two oxlint code renames, the output diffs empty against master.

• No Obsidian runtime check, because the bundle is unchanged.

Checklist

• PR title follows Conventional Commits. It becomes the squash-merge commit and drives the released version.
• Linked any related issue(s): none. This follows build(deps): adopt native tooling and replace ESLint #2224 and build: run svelte-check on TypeScript 6 and guard svelte/internal in .ts files #2225.
• Noted release/migration impact. None: dev tooling only, and chore does not release.

Summary by CodeRabbit

• Developer Tools

  • Updated Svelte checks to flag store usage, non-rune syntax, debug inspection, and console calls.
  • Added checks for DOM creation patterns, inline styles, regex lookbehind, and other compatibility-sensitive code.
  • The Svelte policy checker now also applies rune restrictions to shared .svelte.ts modules.

• Documentation

  • Updated tooling guidance to explain the Svelte policy checks and how they complement Oxlint.

📝 Walkthrough

Walkthrough

The project now uses the svelte-policy package for Oxlint rules and Svelte component checks. The changes add policy configuration, replace local tooling, and update tests and documentation.

Changes

Svelte policy package

Layer / File(s)	Summary
Policy rules and Oxlint wiring .oxlintrc.syntax.json, svelte-policy.json, package.json, tooling/oxlint-plugin.mjs	Adds Svelte and restricted-syntax rules, loads the svelte-policy Oxlint plugin, and removes the local Oxlint plugin.
Checker migration and verification package.json, tooling/svelte-policy.mjs, tests/tooling/sveltePolicy.test.ts, tooling/README.md	Runs the package checker directly and imports its checkSvelte API in tests. The tests and documentation describe the updated rules and checking responsibilities. The local checker implementation is removed.

Merge Risk: 🔵 Low · up to 81c0f

The change swaps local Svelte lint tooling for a shared package without changing the shipped bundle. The one remaining concern is that the dependency range is loose; pin it exactly if the project wants strict control over its lint tooling.

_{I’m a rabbit with rules to review,
A fresh policy package to use.
The stores and old syntax
Meet checks in the mix,
While my tests hop through each avenue.}

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Pin the lint tool to 0.1.0.

^0.1.0 also permits later 0.1.x releases. A lockfile refresh could therefore install new checker and Oxlint plugin code without an explicit version change. Pin this dependency exactly and update the lockfile. The package provides both executable tooling interfaces. (docs.npmjs.com)

Based on learnings, security-sensitive dev tooling such as linters should use exact version pins rather than ^ or ~.
