s3-bucket-toolkit

CircleCI

S3 Bucket APIs calls made easy

  • Provide Promisified AWS API methods
  • Use recommended listObjectsV2
  • Paginate or list all items from the bucket
  • Upload multiple files
  • Delete all Versions and Markers from a particular file

Install

$ npm i s3-bucket-toolkit --save

Configure

const AWSBucket = require('s3-bucket-toolkit');
 
const bucket = new AWSBucket({
  accessKeyId: 'your-access-key-here',
  secretAccessKey: 'your-secret-here',
  region: 'us-east-1',
  bucketACL: 'public-read',
  bucketName: 'my-bucket',
  pagingDelay: 500, // (optional) set a global delay in between s3 api calls, default: 500ms
});
 

Usage

Get Upload URL

Get upload URL

bucket.getUploadUrl({
  ContentType: 'application/javascript',
  Key: 'your-dir/test.js'
}).then(function(res){
  /* Signed URL => res.signedUrl */
}).catch(function(err){
  /* err */
});
 
/*
Result:
{
  signedUrl: 'https://your-bucket.s3.amazonaws.com/your-dir/test.js?AWSAccessKeyId=...'
}
*/

Upload File

bucket.uploadFile({
  filePath: './test/upload-test.txt',
  Key: 'upload-test.txt'
}).then(function(res){
  /* res.url => S3 upload url */
}).catch(function(err){
  /* err */
});
 
/*
 Result:
{ response: { ETag: '"abc.."' },
  url: 'https://my-bucket.s3.amazonaws.com/upload-test.txt' }
*/

Copy File

copyFile(Object, Boolean) function can copy files between buckets or in the same bucket. Pass a second parameter as true when copying files inside the same bucket (will automatically append the bucket prefix). Otherwise pass the entire bucket URL.

bucket.copyFile({
  CopySource: 'upload-test.txt',
  Key: 'upload-test-copied.txt'
}, true).then(function(res){
  /* res.url => S3 copy url */
}).catch(function(err){
  /* err */
});
 
/*
 Result:
{ response: { ETag: '"abc..."', CopySourceVersionId: 'def...', CopyObjectResult: { ... } },
  url: 'https://your-bucket-name.s3.amazonaws.com/upload-test-copied.txt' } }
*/

Copy File Multipart

copyFileMultipart(Object, Boolean, fileSize) function can copy files greater than 5mb between buckets or in the same bucket. Pass a second parameter as true when copying files inside the same bucket (will automatically append the bucket prefix). Otherwise pass the entire bucket URL.

bucket.copyFileMultipart({
  CopySource: 'upload-test.txt',
  Key: 'upload-test-copied.txt',
}, true, 50000000).then(function(res){
  /* res.url => S3 copy url */
}).catch(function(err){
  /* err */
});
 
/*
 Result:
{ response: { ETag: '"abc..."', CopySourceVersionId: 'def...', CopyObjectResult: { ... } },
  url: 'https://your-bucket-name.s3.amazonaws.com/upload-test-copied.txt' } }
*/

    Key: 'upload-test-1.txt'
  }, {
    filePath: './test/upload-test-2.txt',
    Key: 'upload-test-2.txt'
  }]
}).then(function(res){
  /* res => Array of file upload status responses */
}).catch(function(err){
  /* err */
});
 
/*
 Result:
[ { response:
   { ETag: '"abc..."',
     VersionId: '123..' },
  url: 'https://your-bucket.s3.amazonaws.com/upload-test-1.txt' },
{ response:
   { ETag: '"def.."',
     VersionId: '456...' },
  url: 'https://your-bucket.s3.amazonaws.com/upload-test-2.txt' } ]
