fix(create): align Biome formatter with starter files by tannerlinsley · Pull Request #577 · TanStack/cli

tannerlinsley · 2026-11-08T16:30:32Z

Fresh Biome starters now use two spaces, single quotes, and semicolons only where needed. The generated config also passes its own formatter.

Verified Biome 2.4.5 format and lint in fresh standard and blank React and Solid apps outside the repo. The create package build and type compilation passed.

Fixes #576.

Summary by CodeRabbit

New Features
- Generated React and Solid starter projects now use consistent Biome formatting defaults: two-space indentation, single quotes, and optional semicolons omitted.

Walkthrough

Generated React and Solid starter Biome configurations now use two-space indentation, single quotes, and optional semicolons. The React template also updates its schema URL and removes an empty bundler conditional. A patch changeset records the update.

Changes: Starter Biome Defaults

Layer / File(s)	Summary
Align generated starter formatting defaults `.changeset/biome-starter-format.md`, `packages/create/src/frameworks/react/toolchains/biome/assets/biome.json.ejs`, `packages/create/src/frameworks/solid/toolchains/biome/assets/biome.json.ejs`	The React and Solid Biome templates use two-space indentation, single quotes, and optional semicolons. The React template also changes its schema URL and removes an empty bundler conditional. The changeset records a patch release for `@tanstack/create`.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix · Severity of issue fixed: Low

Merge Risk: Low · up to 8ecac

Fresh apps generated through the edge path can fail the Biome format check on a couple of starter files. The failures are formatting-only and easy to fix by updating those templates, so the change is mergeable with that follow-up.

Full details: Title check

Explanation

The title "fix(create): align Biome formatter with starter files" matches the main change. The raw summary and objectives show the Biome configs for the React and Solid starters now use two-space indentation, single quotes, and no unnecessary semicolons, so the generated config matches the starter files. The title names the package, the Biome formatter, and the goal. It is short and specific, and it does not use vague terms.

Full details: Linked Issues check

Explanation

Issue #576 requires the generated biome.json to match the starter file style: two-space indentation, single quotes, and no unnecessary semicolons. At the reviewed head, both packages/create/src/frameworks/react/toolchains/biome/assets/biome.json.ejs and packages/create/src/frameworks/solid/toolchains/biome/assets/biome.json.ejs set formatter.indentStyle to "space" with indentWidth 2, javascript.formatter.quoteStyle to "single", and javascript.formatter.semicolons to "asNeeded". The previous values (tab indentation, double quotes, required semicolons) are gone from both files. The change matches the expected behavior in #576. The issue is a coding requirement and the change is a template configuration change. No automated test was added, and none is required by the issue. The PR also states that Biome 2.4.5 format and lint were checked manually in generated apps. That manual check was not re-run during this review, and it does not change the result. Windows is named as the platform, but the issue does not state a platform-specific coding requirement. Searches of the repository were truncated, so other unrelated Biome templates were not fully enumerated. The visible frameworks listing showed no other biome.json.ejs file in the reviewed paths.

Full details: Out of Scope Changes check

Explanation

The whole-PR changes (merge base efb68bd to head 8ecac79) touch two Biome template files and one changeset. The two templates change formatter and JavaScript formatter settings to the values required by #576. The Biome schema URL is pinned to the 2.4.5 schema on biomejs.dev, which matches the Biome version named in the PR description. The summary also reports removal of an empty bundler template conditional in the React template. This cleanup is in the same file and does not alter the generated behavior. The changeset documents the patch release for @tanstack/create, which is the release note for the template change. No change was found that lacks a connection to #576.

Align the TanStack Query router template with these defaults.

For edge-generated React apps with Query and without routerOnly, src/router.tsx retains the double-quoted import and optional semicolons. biome check can report these as formatting errors. The CLI generator formats them before writing.

Align the Solid root route template with these defaults.

For a non-router-only app generated through the edge API, both root route branches retain a double-quoted stylesheet import and an unnecessary semicolon. Biome includes this file, so biome check reports a formatting error. Update both branches to match the Biome defaults.
