AWS4 React Native

NOTE: This package is a stabe fork of aws4 and aws4-react-native modified to work with React Native apps. With the most important change - fix Buffer dependencies. The core Node JS module querystring has been replaced by querystring-browser, and crypto has been replaced by a standalone javascript file crypto.js generated using browserify.

What follows is the a slighly modified README from aws4.

Example

1import aws4 from 'react-native-aws4';
2
3// given an options object you could pass to http.request
4const opts = {
5  host: 'sqs.us-east-1.amazonaws.com',
6  path: '/?Action=ListQueues'
7};
8
9// alternatively (as aws4 can infer the host):
10opts = {
11  service: 'sqs', 
12  region: 'us-east-1', 
13  path: '/?Action=ListQueues'
14}
15
16// alternatively (as us-east-1 is default):
17opts = {
18  service: 'sqs', 
19  path: '/?Action=ListQueues'
20}
21
22aws4.sign(opts) // assumes AWS credentials are available in process.env
23
24console.log(opts)
25/*
26{
27  host: 'sqs.us-east-1.amazonaws.com',
28  path: '/?Action=ListQueues',
29  headers: {
30    Host: 'sqs.us-east-1.amazonaws.com',
31    'X-Amz-Date': '20121226T061030Z',
32    Authorization: 'AWS4-HMAC-SHA256 Credential=ABCDEF/20121226/us-east-1/sqs/aws4_request, ...'
33  }
34}
35*/
36
37// we can now use this to query AWS using the standard React Native API
38const url = "https://" + signedOptions.host + signedOptions.path;
39fetch(url, signedOptions)
40  .then(body => body.json())
41  .then(json => console.log(json));
42// The above code is equivalent to the following Node JS request:
43// http.request(opts, function(res) { res.pipe(process.stdout) }).end()
