Installation

translation-app-assessment

This contains example code for the Jan-Feb 2021 engagement on a code review / assessment of Pôle Emploi's voice+translation application.

Main steps

1. Create GCP Infrastructure with Terraform
2. Deploy backend services
3. Create the Firebase application
4. Deploy frontend application
5. Configure security

Create GCP Infrastructure with Terraform

Build Infrastructure - Terraform GCP

Deploy backend services

Build and deploy service (6 services)

Create the Firebase application

Log in to the Firebase console, then click Add project.

Select your existing Google Cloud project from the dropdown menu, then click Continue.

Click Add Firebase.

Enable authentication for your Firebase project to use Firestore:

In the Firebase console, click Authentication from the navigation panel.

Go to the Sign-in Method tab.

Enable Email/Password and the anonymous authentication, for example:

Add Firebase to your app by following the web guide.

Deploy frontend application

The source code of frontend application is in petrranslate project. See the README.md file to install it.

Configure security

Add Cloud Firestore Security Rules

To set up and deploy the firestore security rules, open the Rules tab in the Cloud Firestore section of the Firebase console. Copy the rules from rules.txt Write your rules in the online editor, then click Publish

Edit the API key to add restrictions

You must deploy the web application before the next step in order to have the 2 APIs:

• Identity Toolkit API
• Token Service API

In APIs and Service (on GCP Platform), the Credentials part, we could restrict the API key to specific websites and Api's (only the Identity Toolkit API and Token Service API)

First step:

Second step:

Optionnally, create user

If you use application with Firebase authentication (and not with OIDC mechanism), create user in firebase; this user will be used to access to the application.
