AWS Amplify - How to handle name of resources in different environments - aws-amplify

I used Amplify CLI to add storage and functions. When I deploy these changes, the names have a suffix of the environment name. For example, the dynamo tables are named "table1-dev", "table2-dev" and lambda functions are named "function1-dev" and "function2-dev". This is making code hard to maintain.
Is there a way to fix this or handle this scenario. This is a typical 3-tier architecture, so I need API Gateway, Lambda and DynamoDB components.

firebase documentation terminology

What do we mean by secondary Firebase App? for instance, it is mentioned here in this documentation - https://firebase.flutter.dev/docs/auth/usage
Use multiple projects in your application
Sometimes you need to access
different projects using the same APIs - for example, accessing
multiple database instances. In most cases there is a central Firebase
application object that manages the configuration for all the Firebase
APIs. This object is initialized as part of your normal setup.
However, when you want to access multiple projects from a single
application, you’ll need a distinct Firebase application object to
reference each one individually. It’s up to you to initialize these
other instances.
In both cases, you need to first create a Firebase options object to
hold the configuration data for the Firebase application

Expose firebase functions config to create-react-app?

I'm using two firebase projects: one for development and staging, and another for production. The Firebase CLI allows me to switch projects with firebase use _____.
For the client I'm using create-react-app and implicitly configuring firebase by using the From Hosting URLs.
The trouble comes with configuring each project's connection to third party services. For most services I have separate accounts, so need different keys (and secrets on the server), for development and production.
For firebase functions, I can use functions config vars for each project. Pretty easy.
But what's the best way to do this on the client?
create-react-app has great support for various .env files, but can I link a .env file to a firebase project rather than using their prioritization?
Or is there a way to expose the firebase functions config vars to create-react-app's start, build, and test processes as environment variables? (preferably without building all variables into the public js :-P)
What's the best way to do this?
The best way to do this seems to be to use GCP secret manager :
Secret Manager stores API keys, passwords, certificates, and other
sensitive data. It provides convenience while improving security
https://cloud.google.com/secret-manager/docs/quickstart
Beware, it's a standalone service by GCP, therefore Google charges you to store your API keys. The pricing calculation example they detail, so i'm guessing it's a typical use case, gives a monthly cost of $15.15.
That's not cheap to store dumb API keys.
The other way is to use cloud functions as you did.
The benefits of using GCP SM are that the service can be combined with audit logs, that it has a version management feature, and that you can set permission levels.

Cloud Functions: Store Simple Shared Value Across Instances without Database/VPC?

Writing a firebase/google cloud function, and need to store an environment value for use across multiple function calls. That value expires and needs to be re-fetched on occasion and updated in production.
I'm looking for a lightweight option for that. Seems all the advice I can find is that you need to spin up a VPC and create a dedicated Redis instance... or you need to create a cloud database and store it there... I just need to save a simple string, and it seems like an awful lot of infrastructure to do that.
One would think environment variables would work, but you can only set on the command line and they are only refreshed on deploy...
To store environment data, you can use the firebase
functions:config:set command.
To get environment data, you can use the functions.config() function.
See https://firebase.google.com/docs/functions/config-env.
So, is there a way to update/set a value in my code? I cannot rely on the command line to update it as it expires, like a cron to update and redeploy.
In Google Apps Script, for example, I'd just use the 'cache' helper service and store the value for a few hours. Any equivalent cache available to cloud functions without resorting to storing on GCS or in a database (it's a single, simple token string...)? Thanks.
Cloud Functions does not offer any form of shared environment variables between functions. You will need to look to an external source such as Cloud Secrets Manager, Cloud Storage or one of the databases. I use both Cloud Storage and Datastore for this feature. I am now looking into Cloud Secrets Manager as my software usually has secrets as well.

How to reference Firebase Functions config variables from a Firebase-hosted application?

I am transitioning a Heroku-hosted ReactJS/NodeJS application to be hosted on Firebase. Because Firebase only handles static pages I need to reconfigure how my private environmental-specific variables for Development, Staging, Production environments are configured. For example before I defined these sorts of variables:
CLIENT_ID=secret_here
DOMAIN=secret_here
REDIRECT_URI=secret_here
upon the Heroku environment I was deploying to and now I must set them into firebase functions environments from the Firebase CLI for Dev, Staging and Production.
Firebase has documentation on adding environmental configurations to Firebase Functions such that I can add key/value pairs to be accessed at runtime from within a firebase function:
firebase functions:config:set mySecret.key="CLIENT_ID" mySecret.id="secret_here"
however I am unclear how added configuration variables can be accessed from Firebase-hosted static applications (rather than functions).
Is it as simple as simply referencing the firebase functions library from my application and retrieving the defined key from within my application (like so)?
const functions = require('firebase-functions');
...
functions.config().auth0.CLIENT_ID
The variables you define through the link you provided are only available via Cloud Functions. They're not made available directly to the static content served by Firebase Hosting.
If you want, you can make an HTTP function that does nothing but return the JSON from your env vars, and call that from your web content. Bear in mind that you're exposing your secret keys to the world.
The best practice way to handle what I am trying to do is to refactor all of the application logic requiring environment configuration into firebase functions. I can then invoke said functions to reference environment config and execute the code consuming them. This is the answer/solution I needed and didn't have the context to realize earlier. thanks for edging me towards that realization.

Is it good to expose my firebase data structure in client code?

If I create a web app with the serverless client-firebase model, it seems almost 100% my data structure, comprises of nodes, subnodes, duplicate nodes and key:values, is exposed by those DB ref URLs, CRUD and atomic update functions from client js code .
I am not saying that I am not gonna put DB rules, but to only question that exposing so much info which client does not need at all, is it beneficial to hackers only?
I am thinking of create a REST API in the middle and hide firebase queries, but this somehow against the serverless idea. is Cloud Functions for Firebase a cue here?
P.S. I have read related questions below, but they are not the same.
