• TypeScript Support: Built-in TypeScript path mapping with vite-tsconfig-paths
• React Testing: Web preset includes React plugin for component testing
• Coverage Reporting: Comprehensive coverage configuration with multiple reporters
• Performance Optimized: Fork-based test execution with configurable pool options

• Flexible Configuration: Easy to extend and customize for specific project needs

Get Started

Installation

Add the package to your project:

# In your package.json
{
  "devDependencies": {
    "@coze-arch/vitest-config": "workspace:*"
  }
}

Then run:

rush update

Basic Usage

Create a vitest.config.ts file in your project root:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'web', // or 'node' or 'default'
});

API Reference

defineConfig(config, otherConfig?)

The main configuration function that creates a Vitest configuration based on your requirements.

Parameters

config (VitestConfig):

• dirname (string, required): The project root directory (__dirname)
• preset (string, required): Configuration preset - 'default' | 'node' | 'web'
• All other Vitest configuration options

otherConfig (OtherConfig, optional):

• fixSemi (boolean): Enable Semi Design component compatibility fixes

Examples

Default Configuration:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'default',
});

Node.js Application:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'node',
  test: {
    include: ['src/**/*.test.ts'],
    exclude: ['src/**/*.browser.test.ts'],
  },
});

React/Web Application:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'web',
  test: {
    include: ['src/**/*.{test,spec}.{ts,tsx}'],
    setupFiles: ['./src/test-setup.ts'],
  },
});

With Semi Design Components:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'web',
}, {
  fixSemi: true,
});

Custom Coverage Configuration:

import { defineConfig } from '@coze-arch/vitest-config';

export default defineConfig({
  dirname: __dirname,
  preset: 'web',
  test: {
    coverage: {
      all: true,
      threshold: {
        global: {
          branches: 80,
          functions: 80,
          lines: 80,
          statements: 80,
        },
      },
    },
  },
});
