React Native AWS3

React Native Upload AWS S3 is a module for uploading files to S3. The base module is benjreinhart's React Native AWS3(https://github.com/benjreinhart/react-native-aws3). The reason I made it new based on his module is that his module has not been uploaded for a long time and causes an SSL error.

npm install --save react-native-aws3

Note on S3 user permissions

The user associated with the accessKey and secretKey you use must have the appropriate permissions assigned to them. My user's IAM policy looks like:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1458840156000",
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:GetObjectAcl",
                "s3:GetObjectVersion",
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:PutObjectVersionAcl"
            ],
            "Resource": [
                "arn:aws:s3:::my-bucket/uploads/*"
            ]
        }
    ]
}

Example

import { RNS3 } from 'react-native-aws3';

const file = {
  // `uri` can also be a file system path (i.e. file://)
  uri: "assets-library://asset/asset.PNG?id=655DBE66-8008-459C-9358-914E1FB532DD&ext=PNG",
  name: "image.png",
  type: "image/png"
}

const options = {
  keyPrefix: "uploads/",
  bucket: "your-bucket",
  region: "us-east-1",
  accessKey: "your-access-key",
  secretKey: "your-secret-key",
  successActionStatus: 201,
  method:"PUT/POST" // default is POST
}

RNS3.put(file, options).then(response => {
  if (response.status !== 201)
    throw new Error("Failed to upload image to S3");
  console.log(response.body);
  /**
   * {
   *   postResponse: {
   *     bucket: "your-bucket",
   *     etag : "9f620878e06d28774406017480a59fd4",
   *     key: "uploads/image.png",
   *     location: "https://your-bucket.s3.amazonaws.com/uploads%2Fimage.png"
   *   }
   * }
   */
});

Usage

put(file, options)

Upload a file to S3.

Arguments:

• file

• uri required - File system URI, can be assets library path or file:// path
• name required - The name of the file, will be stored as such in S3
• type required - The mime type, also used for Content-Type parameter in the S3 post policy

• options

• acl - The Access Control List of this object. Defaults to public-read
• keyPrefix - Prefix, or path to the file on S3, i.e. uploads/ (note the trailing slash)
• bucket required - Your S3 bucket
• region required - The region of your S3 bucket
• accessKey required - Your S3 AWSAccessKeyId
• secretKey required - Your S3 AWSSecretKey
• successActionStatus - HTTP response status if successful, defaults to 201
• awsUrl - AWS S3 url. Defaults to s3.amazonaws.com
• timeDelta - Devices time offset from world clock in milliseconds, defaults to 0

Returns an object that wraps an XMLHttpRequest instance and behaves like a promise, with the following additional methods:

• progress - accepts a callback which will be called with an event representing the progress of the upload. Event object is of shape
  • loaded - amount uploaded
  • total - total amount to upload
  • percent - number between 0 and 1 representing the percent completed
• abort - aborts the xhr instance

Examples:

RNS3.put(file, options)
  .progress((e) => console.log(e.loaded / e.total)); // or console.log(e.percent)

RNS3.put(file, option)
  .abort();

TODO

• Support DeleteObject and (authenticated) GetObject operations.
