2.4.1

Patch Changes

#9092 6edd600 Thanks @ematipico! - Fixed #9052. This PR reverts changes introduced by https://github.com/biomejs/biome/pull/8519, which caused unwanted changes on how paths are resolved.
#9091 3bf674d Thanks @ematipico! - Fixed #9090, where SCSS files were incorrectly processed by Biome. This was a regressions caused by the latest developments for supporting SCSS out of the box.
#9100 66931a8 Thanks @siketyan! - Fixed #9081: The noUnknownPseudoElement rule no longer reports false positives for any known pseudo elements in CSS modules. This was a regression introduced in v2.4.0.
#9102 d01b903 Thanks @ematipico! - Fixed #9095, where Biome didn’t print anything in stdin mode. This was a regression caused by a recent, internal refactor.

2.4.2

Patch Changes

#9103 fc9850c Thanks @dyc3! - Fixed #9098: useImportType no longer incorrectly flags imports used in Svelte control flow blocks ({#if}, {#each}, {#await}, {#key}) as type-only imports.
#9106 f4b7296 Thanks @dyc3! - Updated rule source metadata for rules from html-eslint.

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noConditionalExpect. This rule disallows conditional expect() calls inside tests, which can lead to tests that silently pass when assertions never run.

1
// Invalid - conditional expect may not run
2
test("conditional", async ({ page }) => {
3
  if (someCondition) {
4
    await expect(page).toHaveTitle("Title");
5
  }
6
});
7

8
// Valid - unconditional expect
9
test("unconditional", async ({ page }) => {
10
  await expect(page).toHaveTitle("Title");
11
});

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightElementHandle. Prefers locators to element handles.
```
1
const el = await page.$(".btn");
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightEval. Disallows page.$eval() and page.$$eval() methods.
```
1
await page.$eval(".btn", (el) => el.textContent);
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightForceOption. Disallows the force option on user interactions.
```
1
await locator.click({ force: true });
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightMissingAwait. Enforces awaiting async Playwright APIs.
```
1
const el = page.locator(".btn");
2
el.click(); // Missing await
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightNetworkidle. Disallows deprecated networkidle wait option.
```
1
await page.goto(url, { waitUntil: "networkidle" });
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightPagePause. Disallows page.pause() debugging calls in committed code.
```
1
await page.pause();
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightUselessAwait. Disallows unnecessary await on synchronous Playwright methods.
```
1
// Incorrect - locator() is synchronous
2
const loc = await page.locator(".btn");
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightWaitForNavigation. Prefers modern navigation APIs over deprecated waitForNavigation().
```
1
await page.waitForNavigation();
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightWaitForSelector. Prefers locators over deprecated waitForSelector().
```
1
await page.waitForSelector(".btn");
```
#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule noPlaywrightWaitForTimeout. Disallows hard-coded timeouts with waitForTimeout().
```
1
await page.waitForTimeout(5000);
```
#8960 4a5ff40 Thanks @abossenbroek! - Enhanced noSkippedTests to detect Playwright patterns (.fixme, test.describe, test.step, bracket notation, bare calls). Consolidated noPlaywrightSkippedTest into this rule.
#9101 0c0fb6f Thanks @siketyan! - Fixed #9080: The noUnusedVariables rule no longer reports a top-level Props interface or type alias as unused in Astro files.

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule useExpect. This rule ensures that test functions contain at least one expect() assertion.

1
// Invalid - test without assertion
2
test("no assertion", async ({ page }) => {
3
  await page.goto("/");
4
});
5

6
// Valid - test with assertion
7
test("has assertion", async ({ page }) => {
8
  await expect(page).toHaveTitle("Title");
9
});

#8960 4a5ff40 Thanks @abossenbroek! - Added the nursery rule usePlaywrightValidDescribeCallback. Validates that describe callback signatures are not async.
```

test.describe("suite", async () => {});
```

2.4.3 Latest

Patch Changes

#9120 aa40fc2 Thanks @ematipico! - Fixed #9109, where the GitHub reporter wasn’t correctly enabled when biome ci runs on GitHub Actions.
#9128 8ca3f7f Thanks @dyc3! - Fixed #9107: The HTML parser can now correctly parse Astro directives (client/set/class/is/server), which fixes the formatting for Astro directives.
#9124 f5b0e8d Thanks @ematipico! - Fixed #8882 and #9108: The Astro frontmatter lexer now correctly identifies the closing --- fence when the frontmatter contains multi-line block comments with quote characters, strings that mix quote types (e.g. "it's"), or escaped quote characters (e.g. "\").
#9142 3ca066b Thanks @THernandez03! - Fixed #9141: The noUnknownAttribute rule no longer reports closedby as an unknown attribute on <dialog> elements.
#9126 792013e Thanks @ematipico! - Added missing Mocha globals to the Test domain: context, run, setup, specify, suite, suiteSetup, suiteTeardown, teardown, xcontext, xdescribe, xit, and xspecify. These are injected by Mocha’s BDD and TDD interfaces and were previously flagged as undeclared variables in projects using Mocha.
#8855 6918c9e Thanks @ruidosujeira! - Fixed #8840. Now the Biome CSS parser correctly parses not + scroll-state inside @container queries.
#9111 4fb55cf Thanks @Jayllyz! - Slightly improved performance of noIrregularWhitespace by adding early return optimization and simplifying character detection logic.
#8975 086a0c5 Thanks @FrankFMY! - Fixed #8478: useDestructuring no longer suggests destructuring when the variable has a type annotation, like const foo: string = object.foo.
