GCS Pre-Signed URL Upload Example

This repository contains two JavaScript scripts for uploading files to Google Cloud Storage.

Script 1: generate-urls.js

This script generates a signed URL for uploading a file to Google Cloud Storage using the @google-cloud/storage library. The signed URL is valid for 30 minutes and can be used to upload a image/png file.

Script 2: upload.js

This script uses the fetch and fs libraries to upload a file to a given signed URL. The file is read into memory and uploaded using an HTTP PUT request. The content type header is set to "image/png".

Requirements

• Node.js
• A Google Cloud Platform project with billing enabled
• A Google Cloud Storage bucket
• A service account key file in JSON format (see https://cloud.google.com/iam/docs/creating-managing-service-account-keys)
• The @google-cloud/storage library (see https://www.npmjs.com/package/@google-cloud/storage)

Usage

1. Copy the .env.example file to .env and replace the placeholder values with the actual values relevant to your setup.
2. Run npm install to install the required libraries
3. Run npm run generate-urls to generate a signed URL
4. Copy the signed URL from the console output and add it to the .env file
5. Run npm run upload to upload a file to the signed URL
