perf(lint/js): optimize some rule queries and unit test call shared logic by dyc3 · Pull Request #11441 · biomejs/biome

dyc3 · 2026-08-21T02:00:15Z

Summary

I had my clanker do a quick performance pass when I was trying a new tool. I had it do some targeted benchmarks:

Benchmark	Final	Change
`useNamedCaptureGroup`	14.623 ms	−16.1%
`noMisplacedAssertion`	14.730 ms	−23.6%
`contains_a_test_pattern`	275.19 ns	−30.0%
`contains_it_call`	539.32 ns	−19.0%

So we'll see if they appear in codspeed.

Walkthrough

The changes narrow syntax queries for UseNamedCaptureGroup and NoMisplacedAssertion. They pass typed syntax nodes to rule logic and remove redundant traversal. Test-pattern detection replaces HashSet with SmallVec and pairwise duplicate checks. A regression test covers repeated modifiers in a longer test chain. A patch changeset documents performance improvements across eight lint rules.

Merge Risk: 🔵 Low · up to 19501

The PR optimizes JavaScript lint-rule queries and shared test-call analysis, but the current changesets still need follow-up because one omits a directly affected rule and the user-facing changesets lack required issue links. This is a bounded merge-readiness risk rather than evidence of runtime breakage.

🚥 Pre-merge checks | ✅ 4

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly summarises the main performance changes to JavaScript lint queries and shared unit-test call logic.
Description check	✅ Passed	The description directly relates to the changeset and includes benchmark results plus the test plan.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.

Sweet! I think one changeset for all rules is enough

- Optimize callee pattern collection with SmallVec - Restrict lint queries to relevant call and regex nodes - Correct misplaced assertion handling for nested test calls

As in HTML, a `<` that cannot open a tag is text and needs no escaping. - [#11438](biomejs/biome#11438) [`3133ffa`](biomejs/biome@3133ffa) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed [#8294](biomejs/biome#8294): an Astro expression holding only a comment is no longer reported as a parse error, which also stopped the whole file from being formatted. ```astro <div>{/* a note */}</div> <div class={/* a note */}>x</div> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed [#9165](biomejs/biome#9165): an empty Astro expression such as `<div>{}</div>` no longer fails to parse. Astro renders `{}` as nothing. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed Astro expressions containing a comment failing to parse. ```astro <div>{/* block comment */ x}</div> <div>{/* only a comment */}</div> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Added support for Astro's fragment shorthand. ```astro <> <p>a</p> </> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed an Astro frontmatter block being cut short by a closing tag inside a string or comment. ```astro --- const a = "</script>"; // </script> in a comment --- ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `---` being read as an Astro frontmatter fence when markup precedes it. Astro only recognizes frontmatter at the very start of a file, so a file opening with a comment now has no frontmatter, and its `---` lines are content. ```astro  --- this is text, not frontmatter --- ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed an Astro frontmatter block ending early on a line that merely starts with a dash. ```astro --- --count; --- ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed the children of an Astro element carrying `is:raw` being parsed as markup instead of raw text. This now also covers `<script>` and `<style>`, whose contents Astro emits verbatim rather than processing, so they are no longer linted as JavaScript or CSS. ```astro <article is:raw><% awesome %></article> <script is:raw>{{ mustache }}</script> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed Astro rejecting attribute names that start with a colon, such as `:href`. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed the Astro parser failing to recover from a malformed closing tag such as `<div></{<//`, so that a later mistake is reported where it happens rather than cascading. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{` inside an Astro `<math>` element opening an expression. MathML is foreign content where Astro parses no expressions, so LaTeX such as `R^{2x}` now survives as text. `<svg>` is unaffected. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{{` at the start of an Astro expression being read as an interpolation. Astro has no `{{ }}` syntax, so `{{ a: 1 }}` and `<Comp a={{ b: 1 }} />` are object literals. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed expressions inside an Astro `<pre>` or `<textarea>` being read as raw text. Astro parses both as ordinary elements, so their markup and interpolations are now parsed, and a variable used only inside one is no longer reported as unused. ```astro <pre>{value}</pre> <textarea><div>{value}</div></textarea> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Added support for template literal attribute values in Astro, such as ``<div class=`a ${b} c`>``. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed Astro rejecting HTML5 unquoted attribute values that contain `` ` ``, `=`, `'` or `"`, such as `<a href=a=b>` and `<a href=a'b>`. - [#11393](biomejs/biome#11393) [`dec5a8f`](biomejs/biome@dec5a8f) Thanks [@1678092075](https://github.com/1678092075)! - Fixed [#11207](biomejs/biome#11207): [`useStrictMode`](https://biomejs.dev/linter/rules/use-strict-mode/) no longer reports Vue event handlers such as `@click="count++"`. - [#11431](biomejs/biome#11431) [`c065f99`](biomejs/biome@c065f99) Thanks [@levrik](https://github.com/levrik)! - Fixed [#11429](biomejs/biome#11429): Variables and imports used by Vue same-name bindings such as `:disabled` or `v-bind:disabled` are no longer reported as unused. - [#11409](biomejs/biome#11409) [`405dedb`](biomejs/biome@405dedb) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a memory leak in the LSP server where memory usage kept growing over long editor sessions. - [#11422](biomejs/biome#11422) [`a51eff7`](biomejs/biome@a51eff7) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#11416](biomejs/biome#11416): Biome no longer crashes when parsing incomplete `{let}` or `{const}` declarations in Svelte files. - [#11378](biomejs/biome#11378) [`34b715c`](biomejs/biome@34b715c) Thanks [@Netail](https://github.com/Netail)! - Added extra rule sources from `@eslint/css`. `biome migrate eslint` detects rules in your eslint configurations more reliably. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{#`, `{/`, `{:` and `{@` being read as Svelte block openings in every HTML-like file. They are now Svelte-only, so in HTML, Vue and Angular files a sequence such as `{#if x}` is ordinary text instead of a parse error. - [#11443](biomejs/biome#11443) [`8d45229`](biomejs/biome@8d45229) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#11390](biomejs/biome#11390): [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) no longer performs unnecessary type inference on call arguments when checking methods of non-generic class instances created with `new`. - [#11425](biomejs/biome#11425) [`9c2667b`](biomejs/biome@9c2667b) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#6426](biomejs/biome#6426): GritQL plugins now match and rewrite metavariables embedded in quoted strings. - [#11441](biomejs/biome#11441) [`00317c3`](biomejs/biome@00317c3) Thanks [@dyc3](https://github.com/dyc3)! - Improved performance of [`useNamedCaptureGroup`](https://biomejs.dev/linter/rules/use-named-capture-group/), [`noMisplacedAssertion`](https://biomejs.dev/linter/rules/no-misplaced-assertion/), [`noSkippedTests`](https://biomejs.dev/linter/rules/no-skipped-tests/), [`noExportsInTest`](https://biomejs.dev/linter/rules/no-exports-in-test/), [`noDuplicateTestHooks`](https://biomejs.dev/linter/rules/no-duplicate-test-hooks/), [`noIdenticalTestTitle`](https://biomejs.dev/linter/rules/no-identical-test-title/), [`useTestHooksInOrder`](https://biomejs.dev/linter/rules/use-test-hooks-in-order/), and [`useTestHooksOnTop`](https://biomejs.dev/linter/rules/use-test-hooks-on-top/). </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.

Astro only recognizes frontmatter at the very start of a file, so a file opening with a comment now has no frontmatter, and its `---` lines are content. ```astro  --- this is text, not frontmatter --- ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed an Astro frontmatter block ending early on a line that merely starts with a dash. ```astro --- --count; --- ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed the children of an Astro element carrying `is:raw` being parsed as markup instead of raw text. This now also covers `<script>` and `<style>`, whose contents Astro emits verbatim rather than processing, so they are no longer linted as JavaScript or CSS. ```astro <article is:raw><% awesome %></article> <script is:raw>{{ mustache }}</script> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed Astro rejecting attribute names that start with a colon, such as `:href`. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed the Astro parser failing to recover from a malformed closing tag such as `<div></{<//`, so that a later mistake is reported where it happens rather than cascading. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{` inside an Astro `<math>` element opening an expression. MathML is foreign content where Astro parses no expressions, so LaTeX such as `R^{2x}` now survives as text. `<svg>` is unaffected. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{{` at the start of an Astro expression being read as an interpolation. Astro has no `{{ }}` syntax, so `{{ a: 1 }}` and `<Comp a={{ b: 1 }} />` are object literals. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed expressions inside an Astro `<pre>` or `<textarea>` being read as raw text. Astro parses both as ordinary elements, so their markup and interpolations are now parsed, and a variable used only inside one is no longer reported as unused. ```astro <pre>{value}</pre> <textarea><div>{value}</div></textarea> ``` - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Added support for template literal attribute values in Astro, such as ``<div class=`a ${b} c`>``. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed Astro rejecting HTML5 unquoted attribute values that contain `` ` ``, `=`, `'` or `"`, such as `<a href=a=b>` and `<a href=a'b>`. - [#11393](biomejs/biome#11393) [`dec5a8f`](biomejs/biome@dec5a8f) Thanks [@1678092075](https://github.com/1678092075)! - Fixed [#11207](biomejs/biome#11207): [`useStrictMode`](https://biomejs.dev/linter/rules/use-strict-mode/) no longer reports Vue event handlers such as `@click="count++"`. - [#11431](biomejs/biome#11431) [`c065f99`](biomejs/biome@c065f99) Thanks [@levrik](https://github.com/levrik)! - Fixed [#11429](biomejs/biome#11429): Variables and imports used by Vue same-name bindings such as `:disabled` or `v-bind:disabled` are no longer reported as unused. - [#11409](biomejs/biome#11409) [`405dedb`](biomejs/biome@405dedb) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a memory leak in the LSP server where memory usage kept growing over long editor sessions. - [#11422](biomejs/biome#11422) [`a51eff7`](biomejs/biome@a51eff7) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#11416](biomejs/biome#11416): Biome no longer crashes when parsing incomplete `{let}` or `{const}` declarations in Svelte files. - [#11378](biomejs/biome#11378) [`34b715c`](biomejs/biome@34b715c) Thanks [@Netail](https://github.com/Netail)! - Added extra rule sources from `@eslint/css`. `biome migrate eslint` detects rules in your eslint configurations more reliably. - [#11403](biomejs/biome#11403) [`8f7786f`](biomejs/biome@8f7786f) Thanks [@Princesseuh](https://github.com/Princesseuh)! - Fixed `{#`, `{/`, `{:` and `{@` being read as Svelte block openings in every HTML-like file. They are now Svelte-only, so in HTML, Vue and Angular files a sequence such as `{#if x}` is ordinary text instead of a parse error. - [#11443](biomejs/biome#11443) [`8d45229`](biomejs/biome@8d45229) Thanks [@ematipico](https://github.com/ematipico)! - Fixed [#11390](biomejs/biome#11390): [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) no longer performs unnecessary type inference on call arguments when checking methods of non-generic class instances created with `new`. - [#11425](biomejs/biome#11425) [`9c2667b`](biomejs/biome@9c2667b) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#6426](biomejs/biome#6426): GritQL plugins now match and rewrite metavariables embedded in quoted strings. - [#11441](biomejs/biome#11441) [`00317c3`](biomejs/biome@00317c3) Thanks [@dyc3](https://github.com/dyc3)! - Improved performance of [`useNamedCaptureGroup`](https://biomejs.dev/linter/rules/use-named-capture-group/), [`noMisplacedAssertion`](https://biomejs.dev/linter/rules/no-misplaced-assertion/), [`noSkippedTests`](https://biomejs.dev/linter/rules/no-skipped-tests/), [`noExportsInTest`](https://biomejs.dev/linter/rules/no-exports-in-test/), [`noDuplicateTestHooks`](https://biomejs.dev/linter/rules/no-duplicate-test-hooks/), [`noIdenticalTestTitle`](https://biomejs.dev/linter/rules/no-identical-test-title/), [`useTestHooksInOrder`](https://biomejs.dev/linter/rules/use-test-hooks-in-order/), and [`useTestHooksOnTop`](https://biomejs.dev/linter/rules/use-test-hooks-on-top/). </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
