New Relic Next.js instrumentation

npm status badge Next.js Instrumentation CI codecov

This is New Relic's official Next.js framework instrumentation for use with the New Relic Node.js agent.

This module provides instrumentation for server-side rendering via getServerSideProps, middleware, and New Relic transaction naming for both page and server requests. It does not provide any instrumentation for actions occurring during build or in client-side code. If you want telemetry data on actions occurring on the client (browser), you can inject the browser agent.

Here are documents for more in-depth explanations about transaction naming, segments/spans, and injecting the browser agent.

Note: The minimum supported Next.js version is 12.0.9. If you are using Next.js middleware the minimum supported version is 12.2.0.


Currently this package is not bundled with the agent, and must be installed as a standalone. However, the package depends on the agent so you will get all the capabilities of the agent when loading this package.

npm install @newrelic/next
NODE_OPTIONS='-r @newrelic/next' next start

If you cannot control how your program is run, you can load the @newrelic/next module before any other module in your program. However, we strongly suggest you avoid this method at all costs. We found bundling when running next build causes problems and also will make your bundle unnecessarily large.


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

Load instrumentation

Since Next.js uses webpack to bundle, auto-instrumentation of 3rd party libraries will not work without a shim. The Next.js instrumentation will load as the Next.js project externalizes next.js files. However, other libraries that are being used will not be externalized and thus not instrumented. Follow these steps to ensure your calls to libraries are properly instrumented.

Add the following to next.config.js

const nrExternals = require('@newrelic/next/load-externals')
const nextConfig = {
  webpack: nrExternals 

module.exports = nextConfig;

Custom Next.js servers

If you are using next as a custom server, you're probably not running your application with the next CLI. In that scenario we recommend running the Next.js instrumentation as follows.

node -r @newrelic/next your-program.js

For more information, please see the agent installation guide.

Getting Started

Our API and developer documentation for writing instrumentation will be of help. We particularly recommend the tutorials and various "shim" API documentation.

Client-side Instrumentation

Next.js is a full stack React Framework. This module augments the Node.js New Relic agent, thus any client-side actions will not be instrumented. However, there is an example for injecting New Relic Browser agent to get more information on client-side actions.

For more information, please see the agent compatibility and requirements.

Error Handling

For capturing both the client and server side errors it is best to use pages/_error.js pattern recommended by Next.js documentation on Advanced Error Page Customization. This example can be used to send either client, server or both types of errors to New Relic. The example assumes that both the New Relic Browser and Node.js agents are integrated. The getInitialProps function's if statement checks whether an error was thrown on the server side (typeof window === "undefined") and if it was the case, it requires New Relic Node.js agent and sends an err with noticeError method. Otherwise it assumes the error was thrown on the front-end side, and uses the browser agent to send the error to New Relic by using window.newrelic.noticeError(err).


The module includes a suite of unit and functional tests which should be used to verify that your changes don't break existing functionality.

All tests are stored in tests/ and are written using Tap with the extension .test.js (unit), or .tap.js (versioned).

To run the full suite, run: npm test.

Individual test scripts include:

npm run unit
npm run versioned
