How to get file link from google cloud storage using Node.js ?
To get the signed public link of a file from the Firebase storage, we need a reference to the file in Google Cloud storage. As we just have a path to that file in storage we would first need to create a reference to that object and then get a signed link to that file.
Steps to generate a public link to a file in storage using the file path:
- Get the reference to the storage using a bucket() and file() methods on the storage object from @google-cloud/storage.
- Generate a signed public link for that file using the getSignedUrl method on the reference object created in the first step.
Module Installation: Install the module using the following command:
npm install @google-cloud/storage
The method getSignedUrl() tasks a config object as input and returns a Promise that resolves with the download URL or rejects if the fetch failed, including if the object did not exist.
Example: Filename: index.js
Run the index.js file using the following command:
File in database exists Url is : https://storage.googleapis.com/geeksforgeeks/gfg.png?X-Goog-Algorithm=[token]
