(Firebase) auth guide app

Simulating .env file in nodejs with env.js

This goes inside the env.js file, and imported into base.js:

const env = {
    APIKEY: "apikey-here",
    AUTHDOMAIN: "authdomain-here",
    PROJECTID: "projectid-here"
};

export default env;

Firestore database rules

Adding a reference here in the readme instead of always having to go to firebase to get this. Copy and paste this and modify as needed in subsequent projects:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    //match /{document=**} {
      //allow read, write: if
          //request.time < timestamp.date(2021, 11, 30);
    //}
    
    //match logged in user doc in users collection: allow the user to create if logged in, allow the user to read only his/her own data
    match /users/{userId} {
    	allow create: if request.auth.uid != null;
      	allow read: if request.auth.uid == userId;
    }
    
    //match docs in the guides collection, and allow access if user exists
    match /guides/{guideId} {
    	allow read, write: if request.auth.uid != null;
    }
  }
}

Rules for guides change so that only admins can write to guides in tutorial 21 - Firestore rules for claims. Change guide rules to:

//match docs in the guides collection, and allow access if user exists
match /guides/{guideId} {
  	allow read: if request.auth.uid != null;
	allow write: if request.auth.token.admin == true;
}

In the end, I changed the rules for guides so that everyone (user or not) can read the collapsible lists:

//match docs in the guides collection. Allow read access to anyone, but write access to admin only
match /guides/{guideId} {
  	allow read;
	allow write: if request.auth.token.admin == true;
}

Custom claims and cloud functions

Commands from Tutorial #17 - Intro to custom claims to be able to use firebase cloud functions:

Install firebase tools if you haven't:

npm i -g firebase-tools

Login to firebase accout if you haven't:

firebase login

Install firebase cloud functions (folder and files) in your project:

firebase init functions

Using cloud functions

Info below is for tutorial #18 - cloud function/adding claims.

Cloud functions is no longer available on firebase free (spark) plan. You need to upgrade to blazer plan to be able to deploy to cloud function.

Add the addAdminRole function and content to the functions/index.js file. Next, deploy code in the functions folder to firebase:

firebase deploy --only functions

Note: After successful deploy, click on 'functions' tab on firebase to see the addAdminRole is present there.

Acessing and calling cloud functions in your app with Firebase Modular Web SDK v. 9.0

Resources: firebase doc and this stackoverflow answer.

Note: don't forget to always deploy your functions to firebase when ever you make a change to the firebase functions inside the functions folder.
