New Relic Webpack Plugin

This project is an experimental plugin that allows New Relic's NodeJS Agent to work with webpack compiled server side javascript. This plugin does not automatically instrument any frontend javascript frameworks -- please see New Relic's browser agent documentation for more information on monitoring frontend javascript frameworks.

Installation

We distribute this plugin via NPM. To add it to your project, just run

$ npm install @newrelic/webpack-plugin

Getting Started

One installed, to get started add an externals and plugins section to your webpack configuration that looks something like this

/*...*/

const nodeExternals = require('@newrelic/webpack-plugin/lib/externals')
const NewrelicWebpackPlugin = require('@newrelic/webpack-plugin/lib/NewrelicWebpackPlugin')

module.exports = {
  /* ... */
  externals: [nodeExternals()],
  plugins: [
    new NewrelicWebpackPlugin()
  ]
  /* ... */
}

How This Works

In order to use Newrelic's NodeJS agent with webpack, you'll need to

1. Ensure the modules New Relic instruments are listed as webpack externals.
2. Add require('newrelic') to the top of your generated sources.

This package allows you to do both. The nodeExternals function

const nodeExternals = require('newrelic-webpack-plugin/lib/externals')

/* ... */

module.exports = {
  /* ... */
  externals: [nodeExternals()],
  /* ... */
}

is borrowed from webpack-node-externals, which is the de-facto standard way to use webpack with NodeJS server side projects. If a module the agent instruments is not listed as a webpack external, the agent will not function properly.

The NewrelicWebpackPlugin

const NewrelicWebpackPlugin = require('newrelic-webpack-plugin/lib/NewrelicWebpackPlugin')

module.exports = {
  /* ... */
  plugins: [
    new NewrelicWebpackPlugin()
  ]
  /* ... */
}

ensures that a require('newrelic') statment is added to the top of any .js asset file generated by webpack.

Testing

You can run tests for this repository via npm

$ npm run test
