Setup GCP Cloud Storage

To use Google Cloud Storage, change the FILE_STORAGE_PROVIDER variable fo the backend/.env file to use gcp.


Go to and create an account.Create a new project for the development environment.Go to Storage > Browser and create a new Bucket.Save the bucket name on the FILE_STORAGE_BUCKET variable. The value must be your bucket-name.

In the example of this image, it will be


The service key

Now our app needs a service key to be able to access the bucket.Create a service account key that has permission to manage Google Cloud Storage buckets. Follow this:

After you download the JSON file, you will see that it looks like this:


"type": "service_account",

"project_id": "...",

"private_key_id": "...",

"private_key": "...",

"client_email": "...",

"client_id": "...",

"auth_uri": "...",

"token_uri": "...",

"auth_provider_x509_cert_url": "...",

"client_x509_cert_url": "..."


Now we must place this entire file into a single environment variable.If you use VSCode, you can use the join lines command.Now place this line on


GOOGLE_CLOUD_PLATFORM_CREDENTIALS = { "type": "service_account", "project_id": "...", "private_key_id": "...", "private_key": "...", "client_email": "...", "client_id": "...", "auth_uri": "...", "token_uri": "...", "auth_provider_x509_cert_url": "...", "client_x509_cert_url": "..." }


Install the in to your account by calling gcloud auth login .

Create a gcp-cors.json file on the same folder that you are at the command line


"maxAgeSeconds": 3600,

"method": ["GET", "HEAD", "POST", "PUT"],

"origin": ["*"],

"responseHeader": ["Content-Type", "Access-Control-Allow-Origin"]


Run this script. Make sure you replace the your-bucket-name by the bucket you created!

gsutil cors set gcp-cors.json gs://your-bucket-name

Done! You are now ready to use the Google Cloud File storage on your project.




I love finding patterns and concluding insights out of it. After working as Employee, a Consultant, a Freelancer I figured out mostly we start our project or a module or microservice either by copying an existing code or base repositories from GitHub lets say. And then spend a lot of time on customising it, analysing pitfalls, making it work so that I can start wrinting business logic for the work. So, I started POC-ing FAB Builder so that I get a trailered project targetted to my requirements and on which I can start wrinting business logic within few mins. This makes my life easy and my clients get a better quality products which are easy to modify and easy to maintain.
