The problem is when I run my app, it works fine. But when I refresh it, most of the time I get below msg.

The selector "my-app" did not match any elements

But the strange thing is that many times when I refresh my app it works also.

So ultimately I have a strange behavior of my app and unable to figure this out. Sometimes it works sometimes doesn't...

Any suggestion, can't come up with code???

Note : I don't have complex structure or components yet but simple implementation.

This happened to me because I was importing my code in the head tag, so it was potentially running and attempting to bootstrap before the DOM was ready.

You can either move the script to the bottom of the body tag, or put the bootstrap code within an event listener:

document.addEventListener("DOMContentLoaded", function(event) {
  bootstrap(AppComponent);
});

or:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Example app</title>
  </head>
  <body>
    <my-app></my-app>
  </body>
  <script src="main.js" charset="utf-8"></script>
</html>

Things to do:

  1. Go to app.module.ts (to main modules, in most cases this is a name)
  2. Check if you have part "boostrap:" - if no add:

    bootstrap: [AppComponent] // where AppComponent is your main component

  3. Check if it works now, if not - go to AppComponent and check your selector. It should be same as tags in body in index.html

so index.html should contain something like this:

<body>
  <app-root>Loading...</app-root>
</body>

where instead of <app-root> you should use selector from main AppComponent

  1. If you are using your angular app in external website then you should consider using defer in headers for angular files

I got same issue when I use Angular Universal. But it is because I am using BrowserModule in main.node.ts, the solution is

  imports: [
    UniversalModule,
    BrowserModule   // <- delete this will solve the issue
  ],

  • post the full error message or either portion of code or my-app component.
  • In IE11 - Potentially unhandled rejection [2] The selector "micropuppy-app" did not match any elements and In FF- 'EXCEPTION: The selector "my-app" did not match any elements BaseException@cdnjs.cloudflare.com/ajax/libs/angular.js/2.0.0-beta.7/… ..... ... ... .. and continue'
  • I've seen this couple of times - it's an IE issue, specifically how it loads scripts if I remember correctly. I'm afraid I don't know the fix for it, was long time ago, but hopefully it can point you in the right direction.
  • Sasxa, I m facing this problem in FF also. I don't know whats the problem. N feel helpless...
  • There is no main.js script inclusion in the plunker demos in the typescript documentation. Athough I do have the error.
  • I didn't get this error until I tried to bundle my compiled typescript files.
  • I faced the same issue while using webpack for module bundling.... and once i placed the script after .. body tag.. it's working...
  • You can also attach it to the window.onload event: window.onload = function(){ platformBrowserDynamic().bootstrapModule(AppModule); }
  • OMG I was banging my head on the wall for so long trying to figure this out and it was so simple. Thank you!
  • There appears to a be problem with the angular-cli creating an app-root reference in index.html file, while the Tour of Heroes tutorial entrypoint ts file refers instead to my-app. IMO the two should use the same naming convention since the Angular team have been recommending angular-cli as the best way to create a project.
  • Somewhat similar, just in case anybody facing this issue with webpack-dev-server (WDS) - I had built my app when selector was <app-root> and launched the app using WDS. Then I changed selector to <my-app> in my component and index.html. That is when I started getting above error. Problem was, index.html under 'dist' folder was not updated. I stopped WDS, built my app again and then launched app. Everything started working just fine!
  • <body> tag fixed it
  • Thank You! It Solved my problem.
  • This isn't true for the latest versions of Angular. These days BrowserModule replaces UniversalModule but an appId is passed as a parameter so that client and server can exchange. See here: github.com/angular/universal/blob/…
  • This answer works for majority of cases for this error. This really should be the answer.
