How to use the AWS SDK for JavaScript with B2

B2 can easily be configured for use with the AWS SDK for JavaScript thanks to the S3 Compatible API. Below is an example of a sample.js that has been configured to set credentials, create a bucket, and upload a file.

// Load the SDK and UUID
var AWS = require('aws-sdk');
var uuid = require('node-uuid');

// Create an S3 client
var credentials = new AWS.SharedIniFileCredentials({profile: 'b2'});
AWS.config.credentials = credentials;
var ep = new AWS.Endpoint('s3.us-west-002.backblazeb2.com');
var s3 = new AWS.S3({endpoint: ep});

// Create a bucket and upload something into it
var bucketName = 'node-sdk-sample-' + uuid.v4();
var keyName = 'hello_world.txt';

s3.createBucket({Bucket: bucketName}, function() {
var params = {Bucket: bucketName, Key: keyName, Body: 'Hello World!'};
s3.putObject(params, function(err, data) {
if (err)
console.log(err)
else
console.log("Successfully uploaded data to " + bucketName + "/" + keyName);
});
});

Content of the config.json

b2@vm:~/aws-nodejs-sample$ more config.json
{"accessKeyId": your_b2_keyid, "secretAccessKey": your_appKey, "region": "us-west-002" }

You can also have the credentials added to the ~/.aws/credentials as a separate profile

 [b2]
aws_access_key_id = your_b2_keyId
aws_secret_access_key = your_b2_appKey

In this case, you won’t need the following 2 lines in the script above 

var credentials = new AWS.SharedIniFileCredentials({profile: 'b2'});
AWS.config.credentials = credentials;

Then run the same script as follows.

  b2@vm:~/aws-nodejs-sample$ AWS_PROFILE=b2 node sample.js
Successfully uploaded data to node-sdk-sample-38cb5413-29c2-46f5-ab2d-4ac4d553f929/hello_world.txt
