Upgrades Vitest from 4.1.4 to 5.0.0 across the monorepo, fixes the handful of things v5 turned into hard errors, and drops the `vi.clearAllMocks()` boilerplate that v5's `clearMocks` default makes redundant. **Changed:** - `vitest`, `@vitest/ui`, `@vitest/coverage-v8` 4.1.4 → 5.0.0 (catalog) - `vi.mock` calls that lived inside `beforeAll`/`beforeEach`/test bodies moved to module scope (v5 throws on nested calls). Affects the Studio and docs setup files and four Studio tests. - `detectBrowser` test restores `navigator` via `vi.unstubAllGlobals()` instead of assigning `global.navigator`, which now reaches jsdom's getter-only property. - `RowEditor.utils.test.ts` restores its `JSON.stringify` spy. It used to leak a throwing mock for the rest of the file, which v5's coverage provider now trips over. A later test in the same file had been asserting the leak's side effect (valid JSON reported as invalid) and now asserts the correct behavior. - `@testing-library/jest-dom` 6.6 → 7.0.1. Its vitest type augmentation resolves through a peer now, so it lands on each package's own `vitest` instead of whichever copy pnpm hoisted. Fixes `toBeInTheDocument` type errors in dev-tools after the reshuffle. - `@testing-library/react` 16.0.0 → 16.3.3 for the React 19 peer range. - `vite: catalog:` added to dev-tools, www, and common. Without it they resolved a newer vite than the catalog pin, which forked a second vitest instance in the lockfile. There's now one. - ai-commands custom matcher types use v5's `Matchers<R, T>` form. - 110 test files: `vi.clearAllMocks()` removed from `beforeEach`/`afterEach` hooks, along with hooks that only did that and the imports they left unused. Calls that also reset/restore mocks are untouched. Second commit, mechanical. **Added:** - `.vitest/` to the root gitignore (v5 writes JSON/JUnit/HTML reporter output there) **Removed:** - `vite-tsconfig-paths` catalog entry and deps. Vitest 5 resolves tsconfig paths itself. Release-age note: this sat in draft with a temporary `minimumReleaseAgeExclude` entry for `vitest` and `@vitest/*` while 5.0.0 was inside the workspace's 3-day `minimumReleaseAge` window. That window has closed, so the exclusion is gone and nothing bypasses the release-age gate. **Perf** (local, medians of 3 runs, same machine): | Suite | v4.1.4 | v5.0.0 | |---|---|---| | studio | 144.1s | 141.7s (-2%) | | studio `--coverage` | 156.9s | 146.4s (-7%) | | ui-patterns | 6.27s | 5.07s (-19%) | | ui `--coverage` | 3.35s | 2.14s (-36%) | | www | 0.89s | 0.47s (-47%) | Studio is dominated by jsdom environment setup per file, which v5 doesn't change. `vitest doctor` recommends keeping the current pool config: the vm pools and `isolate: false` all break tests. ## To test - `pnpm install --frozen-lockfile` succeeds with no `minimumReleaseAgeExclude` entry for vitest. - CI: Studio unit tests, ui, ui-patterns, www, docs, and typecheck/lint should all be green. The lint ratchet was checked locally: warning counts on touched Studio files are identical to master. - `pnpm test:studio` locally passes with coverage (588 files, 6240 tests). - Open a Studio test that uses `toBeInTheDocument` in your editor and confirm no type errors on jest-dom matchers, in Studio and in `packages/dev-tools`. - Known pre-existing failures unrelated to this PR: one dev-tools test (`getEventCountBadge` capped pill) fails on master too. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit ## Tests - Improved test coverage for JSON validation and mobile navigation behavior. - Updated test setup, cleanup, environment configuration, and matcher support across application and shared package suites. - Removed obsolete coverage for alternate MCP transport selection. ## Chores - Streamlined TypeScript path resolution and Vitest reporter output handling. - Updated testing libraries and Vitest tooling across documentation, Studio, website, and shared packages. - Added Vitest reporter output to ignored files. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Alaister Young <10985857+alaister@users.noreply.github.com> Co-authored-by: Ivan Vasilov <vasilov.ivan@gmail.com>
Writing components
Where to create your components
- For components that declare the general structure and layout of a page:
/components/layouts/xxx
- For components that are tightly coupled to a specific interface:
/components/interfaces/xxx
- For components that are meant to be reusable across multiple pages:
/components/ui/xxx
- Note: We're gradually moving files out of the
to-be-cleanedfolder into the respective folders as we refactor
Component structure
- If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an
index.tsxas an entry point - Otherwise it can just be a file on its own
- For example:
-
components/ui - SampleComponentA - SampleComponentA.tsx - SampleComponentA.constants.ts - SampleComponentA.utils.ts - SampleComponentA.types.ts - index.ts - SampleComponentB.tsx
-
Template for building components
// Declare the prop types of your component
interface ComponentAProps {
sampleProp: string
}
// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
return <div>ComponentA: {sampleProp}</div>
}
