eyes-sourcemap-webpack v1.0.3

📋 Introduction

eyes-sourcemap-webpack is a powerful webpack plugin that automatically uploads source maps at build time, enabling efficient debugging and error tracking. It executes after the build process, before the final output of the dist folder.

⚠️ Important Notes

Source maps must be enabled in your webpack build, or the plugin won't function. You need to provide a server-side API to receive uploaded source maps. This plugin is specifically designed for webpack projects.

🚀 Installation

Install the plugin via npm:

npm install eyes-sourcemap-webpack --save-dev

⚙️ Configuration

Below is an example of how to configure the plugin in your vue.config.js:

// vue.config.js
const EyesSourceMap = require('eyes-sourcemap-webpack');

module.exports = defineConfig({
  productionSourceMap: true,
  configureWebpack: {
    plugins: [
      new EyesSourceMap({
        dsn: 'http://your-upload-url', // Required: API base URL for uploads
        token: 'your-project-token',   // Required: Unique project identifier
        uploadScript: ['vue-cli-service build --mode staging'], // Optional: Commands triggering upload
        productionSourceMap: true,     // Optional: Retain source maps (default: false)
        concurrency: 6,                 // Optional: Max upload concurrency (default: 5)
        api: '/api/upload/sourcemap',   // Optional: API endpoint for uploads (default: /api/upload/sourcemap)
        logger: true                   // Optional: Enable logging (default: true)
      })
    ]
  }
})

example with nestJS server:

@Post('sourcemap')
@UseInterceptors(FileInterceptor('file'))
async uploadSourceMap(
  @UploadedFile() file: Express.Multer.File, 
  @Body('apiKey') apiKey: string
) {
  if (!file || !apiKey) {
    throw new CustomHttpException('upload fail', ERROR_CODES.INVALID_PARAMETER);
  }
  return this.uploadService.handleUploadedFile(file, apiKey);
}

async handleUploadedFile(file: Express.Multer.File, apiKey: string) {
  try {
    const filePath = path.join(this.uploadPath, apiKey);

    if (!fs.existsSync(filePath)) {
      fs.mkdirSync(filePath, { recursive: true });
    }

    const fileUrl = path.join(filePath, file.originalname)
    fs.writeFileSync(fileUrl, file.buffer);

    return { message: 'upload success', filename: file.filename };
  } catch (error) {
    throw new CustomHttpException('upload fail', ERROR_CODES.INVALID_PARAMETER);
  }
}
