Mock AWS S3 SDK

This is a very simple interface that mocks the AWS SDK for Node.js. The implementation is incomplete but most basic features are supported.

Available:

  • createBucket
  • deleteBucket
  • listObjects
  • listObjectsV2
  • deleteObjects
  • deleteObject
  • getObject
  • headObject
  • putObject
  • copyObject
  • getObjectTagging
  • putObjectTagging
  • upload
  • getSignedUrl

It uses a directory to mock a bucket and its content.

If you'd like to see some more features or you have some suggestions, feel free to use the issues or submit a pull request.

Example

Instantiate

var AWSMock = require('mock-aws-s3');
AWSMock.config.basePath = '/tmp/buckets/' // Can configure a basePath for your local buckets
var s3 = AWSMock.S3({
	params: { Bucket: 'example' }
});

PutObject/ListObjects

s3.putObject({Key: 'sea/animal.json', Body: '{"is dog":false,"name":"otter","stringified object?":true}'}, function(err, data) {
	s3.listObjects({Prefix: 'sea'}, function (err, data) {
		console.log(data);
	});
});

CreateBucket

var params = { Bucket: 'example' };
s3.createBucket(params, function(err) {
    if(err) {
        console.error(err);
    }
});

DeleteBucket

var params = { Bucket: 'example' };
s3.deleteBucket(params, function(err) {
