New Relic's Node.js agent Server Smoke Tests Node Agent CI

npm status badge

This package instruments your application for performance monitoring with New Relic.

In order to take full advantage of this package, make sure you have a New Relic account before starting. Available features, such as slow transaction traces, will vary based on account level.

As with any instrumentation tool, please test before using in production.


To use New Relic's Node.js agent entails these three steps, which are described in detail below:

  1. To install the agent for performance monitoring, use your favorite npm-based package manager and install the newrelic package into your application:

    $ npm install newrelic

  2. Then, copy the stock configuration file to your program's base folder:

    $ cp ./node_modules/newrelic/newrelic.js ./<your destination>

  3. Now, add your New Relic license key and application/service name to that file:

    /* File: newrelic.js */
    'use strict'
     * New Relic agent configuration.
     * See lib/config/default.js in the agent distribution for a more complete
     * description of configuration variables and their potential values.
    exports.config = {
      app_name: ['Your application or service name'],
      license_key: 'your new relic license key',
      /* ... rest of configuration .. */
  1. Finally, run your program with the newrelic module loaded first by using node's -r/--require flag.
 $ node -r newrelic your-program.js

If you cannot control how your program is run, you can load the newrelic module before any other module in your program.

    const newrelic = require('newrelic')

    /* ... the rest of your program ... */

Getting Started

For more information on getting started, check the Node.js docs.

External Modules

There are several modules that can be installed and configured to accompany the Node.js agent:

  • @newrelic/apollo-server-plugin: New Relic's official Apollo Server plugin for use with the Node.js agent.
  • @newrelic/winston-enricher: Provides distributed trace and span information output as JSON-formatted log messages in Winston. This is most commonly used with the New Relic Logs product.
  • @newrelic/pino-enricher: Provides distributed trace and span information output as JSON-formatted log messages in Pino. This is most commonly used with the New Relic Logs product.
  • @newrelic/mysql(Experimental): Standalone instrumentation for mysql2 and mysql2/promise as well as the same instrumentation for mysql within the Node.js agent.
  • @newrelic/next: Provides instrumentation for the Next.js npm package.

There are several modules included within the Node.js agent to add more instrumentation for 3rd party modules:


Using the API

The newrelic module returns an object with the Node.js agent's API methods attached.

    const newrelic = require('newrelic')

    /* ... */
    newrelic.addCustomAttribute('some-attribute', 'some-value')

You can read more about using the API over on the New Relic documentation site.


These are the steps to work on core agent features, with more detail below:

  • Fork the agent
  • Install its dependencies
  • Run tests using npm
  1. Fork and clone this GitHub repository:

    $ git clone $ cd node-newrelic

  2. Install the project's dependences:

    $ npm install

Then you're all set to start programming.

To run the test suite

  1. Install Docker
  2. Start the Docker services: $ npm run services
  3. Run all the tests using $ npm run test

Available test suites include:

$ npm run unit
$ npm run integration
