Trying to upload zip file to azure storage via node js - node.js

Question

Trying to upload file to azure storage blob using nodejs but facing promise issue. below is my code facing issue while uploading zip file to azure blob storage need to convert this code to callback function or .then function
var re = /\.zip/;
fs.readdir("/tmp/", function(err, files) {
if (err) {
console.log( "Could not list the directory.", err)
process.exit( 1 )
}
console.log("files",files)
var matches = files.filter( function(text) { return re.test(text) } )
console.log("These are the files you have", matches)
var numFiles = matches.length
console.log(numFiles);
if ( numFiles ) {
// Read in the file, convert it to base64, store to S3
for(let i = 0; i < numFiles; i++ ) {
uploadFileToBlob(matches[i])
.then((result: any) => {
console.log('result');
console.log(result);
})
.catch((error: any) => {
console.log(error);
});
}
}
})
const uploadFileToBlob = async (file: any) => {
const { AbortController } = require("#azure/abort-controller");
const { AnonymousCredential, BlobServiceClient, newPipeline } = require("#azure/storage-blob");
const account = 'string';
const accountSas = "sastoken";
const localFilePath = file;
const pipeline = newPipeline(new AnonymousCredential(), {
// httpClient: MyHTTPClient, // A customized HTTP client implementing IHttpClient interface
retryOptions: { maxTries: 4 }, // Retry options
userAgentOptions: { userAgentPrefix: "AdvancedSample V1.0.0" }, // Customized telemetry string
keepAliveOptions: {
// Keep alive is enabled by default, disable keep alive by setting false
enable: false
}
});
const blobServiceClient = new BlobServiceClient(
`https://${account}.blob.core.windows.net${accountSas}`,
pipeline
);
const containerName = 'quickstart';
const containerClient = blobServiceClient.getContainerClient(containerName);
const blobName = file;
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
console.log("blockBlobClient",blockBlobClient);
try {
const result =await blockBlobClient.uploadFile(localFilePath, {
blockSize: 4 * 1024 * 1024, // 4MB block size
concurrency: 20, // 20 concurrency
onProgress: (ev: any) => console.log(ev)
});
console.log("uploadFile succeeds");
return result;
} catch (err) {
console.log(
`uploadFile failed, requestId - ${err.details.requestId}, statusCode - ${err.statusCode}, errorCode - ${err.details.errorCode}`
);
throw err;
}
}
getting output
Promise { <pending> }
I tried to write code in callback function or .then function but getting same error and same code is working in local machine

Please change the following lines of code:
await blockBlobClient.uploadFile(localFilePath, {
blockSize: 4 * 1024 * 1024, // 4MB block size
concurrency: 20, // 20 concurrency
onProgress: (ev) => console.log(ev)
});
console.log("uploadFile succeeds");
to
const result = await blockBlobClient.uploadFile(localFilePath, {
blockSize: 4 * 1024 * 1024, // 4MB block size
concurrency: 20, // 20 concurrency
onProgress: (ev) => console.log(ev)
});
console.log("uploadFile succeeds");
return result;
And then call your uploadFileToBlob method like:
uploadFileToBlob('filename.zip')
.then((result) => {
console.log('result');
console.log(result);
})
.catch((error) => {
console.log(error);
});
UPDATE
Here's the complete code I used. I was able to upload the file successfully:
const uploadFileToBlob = async (file) => {
const { AbortController } = require("#azure/abort-controller");
const { AnonymousCredential, BlobServiceClient, newPipeline } = require("#azure/storage-blob");
const account = 'account-name';
const accountSas = '?sv=2020-04-08&ss=b&srt=sco&se=2021-03-08T18%3A30%3A00Z&sp=rwdxftlacup&sig=pT1d1NJQdu3bcnPA37voTCyQ6jKnmNVYgo1wyiYspDc%3D';
const localFilePath = file;
const pipeline = newPipeline(new AnonymousCredential(), {
// httpClient: MyHTTPClient, // A customized HTTP client implementing IHttpClient interface
retryOptions: { maxTries: 4 }, // Retry options
userAgentOptions: { userAgentPrefix: "AdvancedSample V1.0.0" }, // Customized telemetry string
keepAliveOptions: {
// Keep alive is enabled by default, disable keep alive by setting false
enable: false
}
});
const blobServiceClient = new BlobServiceClient(
`https://${account}.blob.core.windows.net${accountSas}`,
pipeline
);
const containerName = 'container-name';
const containerClient = blobServiceClient.getContainerClient(containerName);
const blobName = file;
const blockBlobClient = containerClient.getBlockBlobClient(blobName);
console.log("blockBlobClient",blockBlobClient);
try {
const result = await blockBlobClient.uploadFile(localFilePath, {
blockSize: 4 * 1024 * 1024, // 4MB block size
concurrency: 20, // 20 concurrency
onProgress: (ev) => console.log(ev)
});
console.log("uploadFile succeeds");
return result;
} catch (err) {
console.log(
`uploadFile failed, requestId - ${err.details.requestId}, statusCode - ${err.statusCode}, errorCode - ${err.details.errorCode}`
);
throw err;
}
}
uploadFileToBlob('filename.zip')
.then((result) => {
console.log('result');
console.log(result);
})
.catch((error) => {
console.log(error);
});
