Please edit your question and include the code you have written so far and the issues you're running into. From your question it looks like someone has given you a coding exercise and you are looking for a readymade solution to that. — Gaurav Mantri, Oct 22 '21 at 09:32

I have tested in my environment

You can use the below javascript function to download files from Azure blob storage :

    async function main() {
        var fs = require('fs');
        const { BlobServiceClient, StorageSharedKeyCredential } = require("@azure/storage-blob");
        const account = "storage account name";
        const accountKey = "storage account key"
        const sharedKeyCredential = new StorageSharedKeyCredential(account, accountKey);
        const blobServiceClient = new BlobServiceClient(
        `https://${account}.blob.core.windows.net`,
        sharedKeyCredential);
        const containerClient = blobServiceClient.getContainerClient("container name");
        const blobClient = containerClient.getBlobClient("blob file name to be downloaded");
        const response = await blobClient.downloadToFile("blob file name to be downloaded");
    main();

When the user clicks download button on the UI, the pdf file stored in Azure blob storage needs to be downloaded. Is this your requirement? – RamaraoAdapa Oct 25 '21 at 07:19
Yes. This is the requirement – Anjali Oct 25 '21 at 07:58
But there will be azure connection required, right? Also Azure REST API call to get the blobs? – Anjali Oct 25 '21 at 08:33
