Installation

``bash
pnpm add --save-dev @apitree.cz/vitest-config vitest
`

If you want to collect code coverage, you also need to install v8 provider:

`bash
pnpm add --save-dev @vitest/coverage-v8
`

$3

Install the package in the root only, use it in multiple workspaces (see Vitest Projects).

Usage

Use one of the following configurations in your vitest.config.ts.

$3

`typescript
export { base as default } from '@apitree.cz/vitest-config';
`

$3

`typescript
export { react as default } from '@apitree.cz/vitest-config';
`

> ⚠️ You will also need to install jsdom for React configuration to work.

$3

`typescript
export { nestjs as default } from '@apitree.cz/vitest-config';
`

$3

You can customize the configuration with mergeConfig function:

`typescript
import { base } from '@apitree.cz/vitest-config';
import { defineConfig, mergeConfig } from 'vitest/config';

export default mergeConfig(
base,
defineConfig({
// project specific config
}),
);
`

> See Options documentation for config reference.

$3

You can also use the configurations as a base for multiple Vitest Projects in a monorepo setup.

Start by defining root vitest.config.ts:

`typescript
import { defineConfig, mergeConfig } from 'vitest/config';

export default defineConfig({
test: {
root: import.meta.dirname,
projects: ['apps/', 'packages/'],
},
});
`

Then, in each project, create vitest.config.js defining specific preset (e.g. apps/react-app/vitest.config.js for an app that requires React preset):

`javascript
import { react } from '@apitree.cz/vitest-config';
import { defineProject } from 'vitest/config';

export default defineProject(react);
`

Assuming the app is named @apitree.cz/react-app, you can run Vitest for this project only:

`bash


From monorepo root

pnpm vitest --project @apitree.cz/react-app --run

From apps/react-app

pnpm vitest --run
