Does the AngularFire service use REST under the hood?
If so is there no limits in the hacker plan, because the Firebase page on pricing says:
REST API requests don't count towards your connection limits
?
回答1:
The AngularFire library uses Firebase's regular JavaScript/Web SDK under the hood. Each client keeps a connection open to Firebase servers, so will count towards the connection limits.
You can easily verify this yourself by creating a minimal AngularFire client and opening it in a few different browsers. After 15-20 minutes you can see the connections showing up in the Analytics tab of your Firebase dashboard.
