This is the authentication service for the whole twitter clone app. It is made with Golang with Firebase Auth as the authentication SaaS.
For now, it just syncs the user data from Firebase Auth to the postgres database.
Authentication and authorization are essential for any microservices architecture. They ensure that only authorized users can access the services, and that they can only access the resources that they are allowed to access.
Implementing your own authentication flow can be complex and time-consuming. This is especially true if you need to support a variety of authentication methods, such as username and password, OAuth, and social login.
Hence, I decided to use Firebase Auth as the authentication SaaS for this project.
Some other alternatives that I might consider in the future are AWS Cognito and Supabase Auth.
Here you will understand how to run and setup the development environment for the auth service in your local machine.
Prerequisites
1. Protobuf
First, you need to generate the protobuf files using buf protobuf cli tool. You can do this by running the following command:
cd proto
buf generate --debug --verboseThis command will generate the protobuf files in the gen/{lang=go}/{service} directory.
Next, There is an init.sql file, so next is to execute the queries in the file to create the tables.
2. Local Docker
Head to github.com/twitter-remake/compose for the docker-compose file and instructions.
3. Configuration
Create the .env file by copying the .env.example file and fill in the values.
Next is to create the firebase-credentials.json file which you can get from the firebase console Settings > Service Accounts > Generate new private key.
4. Run the service
go run main.goIf you have any questions or feedback, feel free to contact me via email
And if you like this project, consider buying me a coffee :)
