This plugin provides seamless bundling of Pino logger and its transports for Rollup and Vite projects. It handles the special requirements of Pino's worker threads and file transports, making them work properly in bundled applications.
npm install -D rollup-plugin-pino-bundle
import { rollup } from 'rollup'; import pinoBundle from 'rollup-plugin-pino-bundle'; const bundle = await rollup({ input: 'src/main.js', plugins: [ pinoBundle({ transports: ['pino-pretty'], // optional transports to include pinoDir: 'custom-pino', // optional custom directory }), ], });
import { defineConfig } from 'vite'; import pinoBundle from 'rollup-plugin-pino-bundle'; export default defineConfig({ plugins: [ pinoBundle({ transports: ['pino-pretty'], // optional transports to include transportsDir: 'custom-transports', // optional custom transports directory }), ], });
Type: string[]
Default: []
An array of pino transport module names to bundle with your application.
Example:
pinoBundle({ transports: ['pino-pretty', 'pino-loki'], });
Type: string
Default: 'pino'
Set custom directory for pino files. This is the root directory where all pino-related files will be placed.
Example:
pinoBundle({ pinoDir: 'custom-pino', });
Type: string
Default: ${pinoDir}/transports
Set custom directory for all transports. By default, it will be a subdirectory of the pinoDir.
Example:
pinoBundle({ transportsDir: 'my-transports', // will be relative to output directory });
The plugin creates the following directory structure in your output folder:
/pino
/pino.js # Main pino bundle
/transports
/pino-file.js # File transport worker
/pino-worker.js # Worker implementation
/thread-stream-worker.js # Thread stream worker
/[transport-name].js # Any additional transports you specify
The plugin implements caching to improve build performance
The package includes TypeScript type definitions out of the box.
Problem: Transports not working in production build
Solution: Make sure to include all required transports in the transports option
