Firebase in a chrome extension

based on stackoverflow Add Cloud firestore library to chrome extension, content_scripts​
in chrome extension manifest file manifest.json add firebase-app.js (https://www.gstatic.com/firebasejs/7.5.0/firebase-app.js) and firebase-firestore.js(https://www.gstatic.com/firebasejs/7.5.0/firebase-firestore.js) as follows
1
...
2
  "content_scripts": [
3
    {
4
      "matches": [
5
        "https://www.wsj.com/*"
6
      ],
7
      "js": [
8
        "firebasejs/7.5.0/firebase-app.js",
9
        "firebasejs/7.5.0/firebase-firestore.js",
10
    ...
Copied!
As well as 
1
  ...
2
  "content_security_policy":"script-src 'self' https://www.gstatic.com/ https://*.firebaseio.com https://www.googleapis.com; object-src 'self'"
3
}
Copied!
then in your extension code you can just initialise firebase as usual eg
1
const firebaseConfig = {
2
    apiKey: "XXX",
3
    authDomain: "XXX",
4
    databaseURL: "XXX",
5
    projectId: "XXX",
6
    storageBucket: "XXX",
7
    messagingSenderId: "XXX",
8
    appId: "XXX",
9
    measurementId: "XXX"
10
  };
11
​
12
firebase.initializeApp(firebaseConfig);
13
const db = firebase.firestore();
14
​
15
// do something with firebase/firestore
Copied!
