Introduction

This nodejs module will move S3 files to another S3 location.

Description

The AWS S3 sdk doesn't come out with a built-in move files operation. This module will handle that for you using the available built-in operations, such copyObject (and deleteObjects if "createCopy" set to false).

This module can move single S3 file, or can move all the files in the specified S3 sourcePath parameter.

/*
 * This nodejs module will move files to another S3 location. It has also an option to just copy the files.
 * @param {options} - parameters, as follows
    {
        sourceBucket: 's3-source-bucket-name',
        sourcePath: 's3-source-prefix-path',
        sourceFiles: ['source-file1.txt', 'source-file2.txt'],
        targetBucket: 's3-target-bucket-name',
        targetPath: 's3-target-prefix-path',
        targetFiles: ['source-file1-moved.txt', 'source-file2-moved.txt'],
        createCopy: false
    }
 * @return {object} - a JSON object containing the details of the files that has been moved or copied.
    {
        s3Bucket: 's3-target-bucket-name',
        s3Objects: [
            '/s3-target-prefix-path/source-file1.txt', 
            '/s3-target-prefix-path/source-file2.txt'
        ]
    }
 */

Usage

1. Move ALL files in the specified S3 sourcePath into the same S3 bucket.

   const s3mv = require('lambda-s3-mv');
   
   const result = await s3mv.move({
       sourceBucket: 's3-source-bucket-name',
       sourcePath: 's3-source-prefix-path',
       targetPath: 's3-target-prefix-path'
   });
   console.log(result);

2. Move ALL files in the specified S3 sourcePath into different S3 bucket.

   const s3mv = require('lambda-s3-mv');
   
   const result = await s3mv.move({
       sourceBucket: 's3-source-bucket-name',
       sourcePath: 's3-source-prefix-path',
       targetBucket: 's3-target-bucket-name',
       targetPath: 's3-target-prefix-path'
   });
   console.log(result);

3. Move specified list of files in the specified S3 sourcePath into the same S3 bucket.

   const s3mv = require('lambda-s3-mv');
   
   const result = await s3mv.move({
       sourceBucket: 's3-source-bucket-name',
       sourcePath: 's3-source-prefix-path',
       sourceFiles: ['source-file1.txt', 'source-file2.txt'],
       targetPath: 's3-target-prefix-path'
   });
   console.log(result);

4. Move specified list of files in the specified S3 sourcePath into the same S3 bucket, and rename files after moved.

   const s3mv = require('lambda-s3-mv');
   
   const result = await s3mv.move({
       sourceBucket: 's3-source-bucket-name',
       sourcePath: 's3-source-prefix-path',
       sourceFiles: ['source-file1.txt', 'source-file2.txt'],
       targetPath: 's3-target-prefix-path',
       targetFiles: ['source-file1-moved.txt', 'source-file2-moved.txt']
   });
   console.log(result);

5. Copy ALL files in the specified S3 sourcePath into the same S3 bucket. "createCopy" set to true.

   const s3mv = require('lambda-s3-mv');
   
   const result = await s3mv.move({
       sourceBucket: 's3-source-bucket-name',
       sourcePath: 's3-source-prefix-path',
       sourceFiles: ['source-file1.txt', 'source-file2.txt'],
       targetPath: 's3-target-prefix-path',
       createCopy: true
   });
   console.log(result);

Important

Please make sure the lambda has read and write access to specifed source S3 Bucket.
