This is New Relic's official Next.js framework instrumentation for use with the New Relic Node.js agent.
This module is a dependency of the agent and is installed by default when you install the 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.
Typically, most users use the version auto-installed by the agent. You can see agent install instructions here.
In some cases, installing a specific version is ideal. For example, new features or major changes might be released via a major version update to this module, prior to inclusion in the main New Relic Node.js agent.
npm install @newrelic/next
NODE_OPTIONS='-r @newrelic/next' next startIf 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.
require('@newrelic/next')
/* ... the rest of your program ... */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.jsFor more information, please see the agent installation guide.
Our API and developer documentation for writing instrumentation will be of help. We particularly recommend the tutorials and various "shim" API documentation.
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, below is a method of adding the New Relic Browser agent to get more information on client-side actions.
import Head from 'next/head'
import Layout, { siteTitle } from '../../components/layout'
import utilStyles from '../../styles/utils.module.css'
import Link from 'next/link'
export async function getServerSideProps() {
// You must require agent and put it within this function
// otherwise it will try to get bundled by webpack and cause errors.
const newrelic = require('newrelic')
const browserTimingHeader = newrelic.getBrowserTimingHeader()
return {
props: {
browserTimingHeader
}
}
}
export default function Home({ browserTimingHeader }) {
return (
<Layout home>
<Head>
<title>{siteTitle}</title>
</Head>
<div dangerouslySetInnerHTML={{ __html: browserTimingHeader }} />
<section className={utilStyles.headingMd}>
<p>It me</p>
<p>
This page uses server-side rendering and uses the newrelic API to inject
timing headers.
</p>
<div>
<Link href="/">
<a>← Back to home</a>
</Link>
</div>
</section>
</Layout>
)
}For static compiled pages, you can use the copy-paste method for enabling the New Relic Browser agent.
For more information, please see the agent compatibility and requirements.
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
