Question

What are some effective methods for integrating APM into a NuxtJS project?

How do you properly set up and activate an Elastic APM agent in a Nuxt.js project?

I followed the instructions from this documentation for a custom Node.js app. The main point emphasized was:

It's crucial to start the agent before loading any other modules in your Node.js application - including http and router.

Even though I added the code snippet below in nuxt.config.js, the APM agent isn't starting or functioning. No errors are appearing in the app logs either.

var apm = require('elastic-apm-node').start({
  serviceName: 'nuxt-app',
  serverUrl: 'http://ELK_APM_SERVER:8200'
})

Is there an alternative method to achieve this?

Answer №1

Our team successfully implemented a solution by utilizing a custom Nuxt module that specifically requires the Node modules for instrumentation after initializing the APM module.

modules/elastic-apm.js:

    const apm = require('elastic-apm-node');
    const defu = require('defu');
    
    module.exports = function() {
      this.nuxt.hook('ready', async(nuxt) => {
        const runtimeConfig = defu(nuxt.options.privateRuntimeConfig, nuxt.options.publicRuntimeConfig);
        const config = (runtimeConfig.elastic && runtimeConfig.elastic.apm) || {};
    
        if (!config.serverUrl) {
          return;
        }
    
        if (!apm.isStarted())  {
          await apm.start(config);
    
          // We then explicitly include the necessary modules that need APM instrumentation,
          // as they would not be instrumented otherwise.
          //
          // Docs: https://www.elastic.co/guide/en/apm/agent/nodejs/master/custom-stack.html
          // Modules: https://github.com/elastic/apm-agent-nodejs/tree/master/lib/instrumentation/modules
          require('http');
          require('http2');
          require('https');
        }
      });
    }

nuxt.config.js:

    module.exports = {
      // Ensure it's in modules and not buildModules
      modules: ['~/modules/elastic-apm'],
      
      publicRuntimeConfig: {
        elastic: {
          apm: {
            serverUrl: process.env.ELASTIC_APM_SERVER_URL,
            serviceName: 'my-nuxt-app',
            usePathAsTransactionName: true // prevent "GET unknown route" transactions
          }
        }
      }
    };

The information provided is outdated and inaccurate as of February 17, 2022

To correct this issue, follow these steps:

1.) Begin by creating a file named nodeApm.js in the root directory with the following code:

const nodeApm = require('elastic-apm-node')

if (!nodeApm.isStarted()) { 
    nodeApm.start()
}

2.) Utilize environment variables to store your configuration. For instance:

ELASTIC_APM_SERVICE_NAME=NUXT_PRODUCTION
ELASTIC_APM_SECRET_TOKEN=yoursecrettokenhere

3.) Update your package.json file accordingly

"scripts": {
    // If you want APM running during development for testing purposes, include it here as well
    "dev": "node -r ./nodeApm.js node_modules/nuxt/bin/nuxt",
    ...
    "start": "node -r ./nodeApm.js node_modules/nuxt/bin/nuxt start",
...

! Note that around 2022, the node_modules bin folder no longer includes the "." in the directory name

! Additionally, many answers tend to omit the required 'start' parameter at the end

"start": "node -r ./nodeApm.js node_modules/nuxt/bin/nuxt start",

After reviewing the situation, it appears that there is no definitive approach to handling this issue using the standard nuxt command line tool. The main issue seems to stem from the fact that the Node's HTTP frameworks are initialized before the nuxt.config.js file can be accessed, preventing any APM agent (such as the elastic agent) from effectively hooking into the modules.

The Nuxt team has provided some suggestions on how to address this problem:

Manually run nuxt with the -r flag

     {
       "scripts": {
         "start": "node -r elastic-apm-node node_modules/nuxt/.bin/nuxt"
       }
     }

Bypass nuxt and incorporate NuxtJS programmatically as a middleware in your chosen framework

     const { loadNuxt } = require('nuxt')
     const nuxtPromise = loadNuxt('start')
     app.use((req, res) => { nuxtPromise.then(nuxt => nuxt.render(req, res)) })

After consulting Alan Storm's solution (Nuxt team), I successfully implemented it with a slight tweak:

To start, I created a new file named nodeApm.js and added the following code snippet:

const nodeApm = require('elastic-apm-node')

if (!nodeApm.isStarted()) { ... // configuration magic }

Then, in the script sections, I included:

"start": "node -r ./nodeApm.js node_modules/nuxt/.bin/nuxt"
