Azure-docs: Azure storage createBlockBlobFromLocalFile returns "Uncaught (in promise) TypeError: fs.stat is not a function"

[knoerregaard]

const path = require('path');
const storage = require('azure-storage');

const blobService = storage.createBlobService('Left out on purpose');
const containerName = 'test-container13';
const sourceFilePath = path.resolve('./attentto-logo.png');
const blobName = path.basename(sourceFilePath, path.extname(sourceFilePath));


exports.createContainer = function () {
  return new Promise((resolve, reject) => {
    blobService.createContainerIfNotExists(containerName, { publicAccessLevel: 'blob' }, err => {
      if (err) {
        reject(err);
      } else {
        resolve({ message: `Container '${containerName}' created` });
      }
    });
  });
};
exports.uploadImage = () => {
  return new Promise((resolve, reject) => {
    blobService.createBlockBlobFromLocalFile(containerName, blobName, sourceFilePath, err => {
      if (err) {
        reject(err);
      } else {
        resolve({ message: `Upload of '${blobName}' complete` });
      }
    });
  });
};

When calling the uploadImage function the code returns this error "Uncaught (in promise) TypeError: fs.stat is not a function"

I call it like this:

          fun.uploadImage().then((data)=>{
            console.log(data)
          });

Hi and thanks for your reply. I followed these instructions here: https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-nodejs

[knoerregaard]

Hi again, My goal is actually to upload from browser - so I think that I am using the wrong API. Is it possible to use createBlockBlobFromBrowserFile instead? The application is a Meteor application.

[TravisCragg-MSFT]

@knoerregaard Here are the available functions inside blobService. There is no default way to upload a file from a URL. There are 2 ways to upload a file using this class, upload from a local file, or upload from a stream. You will most likely need to download the file locally first, or create a read stream from the URL.

If you would like this feature to be added, please submit your feedback Here.

We will now proceed to close this thread. If there are further questions regarding this matter, please tag me in your reply. We will gladly continue the discussion and we will reopen the issue.

@TravisCragg-MSFT Your link is dead. I am trying to use createBlockBlobFromLocalFile and I'm hitting this same error message. Do you have a simple example on how to do this from a react app?

@Adam-Smith-MSFT can you help?
