How to reproduce these conditions

I have multiple environments: integration, testing, staging, production. AngularFirePerformanceModule doesn't seem to work in anything except for integration. The only difference between these environments is the environment variables, and the only one that I can think of that makes materially differences is the enableProdMode from production: true.

Failing test unit, Stackblitz demonstrating the problem

Steps to set up and reproduce

see above. 1 project, 2 env variables

Sample data and security rules
export const environment = {
production: false
}

vs

export const environment = {
production: true
}

Debug output

** Errors in the JavaScript console **
no console log errors

** Output from firebase.database().enableLogging(true); **
not db related

** Screenshots **
can't show screenshots of working performance for other reasons

Expected behavior

performance logged

Actual behavior

doesn't even show that the sdk is setup. contacted google support and they say they haven't gotten anything from this project (in production)

Perhaps the same as #2505, see my comment on that thread for a possible work around.

[vamsiambati]

Using the below code in app.component is registering all the logs in production mode
constructor(private perfSvc:AngularFirePerformance) { this.perfSvc.dataCollectionEnabled.then(dcp=>{ console.log('dcp enabled',dcp) }) }

@jonbcampos-alto I think I'm having the same issue as you. My performance monitoring was logging just fine in the Firebase dashboard up until a couple months ago. Now nothing is being sent over. Do we have to include PerformanceMonitoringService as a provider now since v6?

[jonbcampos-alto]

based on the thread it looks like the tree shaking is overly aggressive and stopping this functionality from working. until there is a fix I think the only option is to turn prod: false. which I don't recommend.

Here my solution:

1. in your app.module.ts import INSTRUMENTATION_ENABLED

import { AngularFirePerformanceModule, PerformanceMonitoringService, INSTRUMENTATION_ENABLED } from '@angular/fire/performance';

2. and set INSTRUMENTATION_ENABLED to true

providers: [ . . . PerformanceMonitoringService, {provide: INSTRUMENTATION_ENABLED, useValue: true}, . . . ],

[jonbcampos-alto]

tested @madHorse54 's solution. no effect.

[Splaktar]

It's possible that this was broken due to lint fixes similar to how 23e2f1e caused #2505.

The related lint fixes for Performance are in ae0ef48. I'm going to take a look and do some debugging there.

[jamesdaniels]

Yeah, looks like this is the case ae0ef48#diff-473350a8df09472fdfe71659bcae05daR36 the logic with the "default" was broken in that commit. If it's null, which is what an @Optional defaults to, it will disable metrics. I'm testing, will cut an RC with a fix for this and the analytics shortly.

[Splaktar]

Yeah, I saw that too but I ran into some issues trying to get the full cycle of build lib, yarn in sample project, ng serve in sample project, etc to see the changes. I haven't found any contributor docs that explain how to best do this development cycle for this project. It seems like I need to rm -rf sample/node_modules/;yarn after every time that I run yarn build to build the library.

[Splaktar]

Posted PR #2595 to solve this after I was finally able to verify the fix locally.

[Splaktar]

Here my solution:

1. in your app.module.ts import INSTRUMENTATION_ENABLED

import { AngularFirePerformanceModule, PerformanceMonitoringService, INSTRUMENTATION_ENABLED } from '@angular/fire/performance';

1. and set INSTRUMENTATION_ENABLED to true

providers: [ . . . PerformanceMonitoringService, {provide: INSTRUMENTATION_ENABLED, useValue: true}, . . . ],

In the meantime, I tried this workaround, but it didn't work for me. I also tried applying the fix in my node_modules/@angular/fire/ directory directly, but that also did not work for me. I guess that I'll wait for the next canary or release 😄

[jamesdaniels]

Will be fixed in 6.0.3 which should be up on NPM shortly.

[Splaktar]

While I verified that the changes in PR #2595 alone fixed this, I didn't test PR #2597 locally. Now that 6.0.3 is released and I've tested it on a few sites, I can confirm that this is not fixed. I am still not getting Firebase Performance logs sent to the server from any of the apps.

It looks like maybe this was actually needed?

[HerbertBodner]

Sorry to confirm that it is NOT fixed. I built a completely new angular app from scratch with v6.0.3 and performance data is only logged when I deploy with:
ng build; firebase use my-project; firebase deploy --only hosting

but not with:
ng build --prod; firebase use my-project; firebase deploy --only hosting

-----------Update-----------
It turns out that custom metrics work fine.

[kyleabens]

Any update on this or workarounds for the time being with v6.0.3?

[HerbertBodner]

I think that tree shaking is the issue.
My workaround: use a custom trace somewhere at startup (eg logon), then also the non-custom/built-in traces seem to work fine!

Thank you for this information. @jamesdaniels I was able to confirm that this is the case. Just adding a simple start/stop trace in your AppComponent seems to avoid having the PerformanceModule tree shaken and then performance logging seems to start working (I need to wait 24 hours to verify that all of the built-in data appears).

[jamesdaniels]

Odd... AngularFirePerformanceModule makes a dummy call to AngularFirePerformance, which should keep it from tree-shaking out & trip the lazy load. Maybe that's getting shaken out since I'm not doing anything with it or the implementation of the promise in AngularFirePerformance requires it to be awaited.

[Splaktar]

@jamesdaniels initially I tried in an app to just do this.angularFirePerformance.trace('app-component-trace') and that got tree shaken.

Then I tried

    this.angularFirePerformance.trace('app-component-trace').then((trace: Trace) => {});

And that seemed to be tree shaken too.

I finally settled on the following to make it start working:

  trace: Trace | null = null;

  constructor(private angularFirePerformance: AngularFirePerformance) {
    this.angularFirePerformance.trace('app-component-trace').then((trace: Trace) => {
      trace.start();
      this.trace = trace;
    });
  }

  ngOnInit(): void {
    if (this.trace) {
      this.trace.stop();
    }
  }

I didn't use await since it complained that the constructor wasn't an async function.
