You get that token from firebase.com when you sign up with them.

Otherwise, you use the MIT Firebase default server just for testing and learning.

It can be used for the API key for your firebase project, which you find on the Project Settings page in the Firebase console. However, in practice, I have found that it is not needed for functional operation.

Thanks, but how can i get that token from firebase.com, or .. Does the token work to authorize a read or write call on the database from my app?

As I previously said, the APIkey, if used in the Token box, seems to have no effect on your ability to connect to your Firebase project. However, your secure rules must be read:true and write:true to be able to read and write.

If you intend to use Firebase Authentication and use secure rules, then you can either use the web component or there are extensions available for accessing your firebase project in these conditions.

If you check DEFAULT in the Firebase component designer settings, then a token will appear. This token will create a reasonably private area for your data via the MIT Firebase realtime database code. You can't / should not try to change this.

If we use authentication and secure rule to write and read data then the inbuilt firebase component doesn't work and so the data changed event. So is it possible to have data changed event using web component?

7

Data changed is not available as a part of the REST API. You can do something if you use a webviewer and some suitable html/JavaScript with your Firebase config .

There is a DataChanged example in this guide

i used an extension for firebase auth for login, so do i need everytime to give email and password for data changed event as webstring ?

As it is setup in the guide, yes, you would need to provide the email and password each call. You could add more html e.g. a button, just to make the dataChanged call and return fresh data from the same projectBucket. Imagibne how it might work if it was a proper web app being used in a browser.

Remember that signins only last an hour before they need to be refreshed.
