# Introduction and Overview

This tiny library is being developed to generate AWS signature version 4 and pre-signed url. This library is designed to be 'universal', i.e., it works both on most browsers and on Node.js just by importing from npm/source code.

# Installation

At your project directory, do either one of the following.

- From npm/yarn:

  ```shell

  $ npm install --save js-aws-sigv4 // npm

  $ yarn add js-aws-sigv4 // yarn

  ```

- From GitHub:

  ```shell

  $ git clone https://github.com/junkurihara/js-aws-signature-v4.git

  ```

Then you should import the package as follows.

```javascript

import jsAwsSigV4 from 'js-aws-sigv4'; // for npm

```

# Usage

## Get signature itself

```javascript

const signingKey = await jsAwsSigv4.getSigningKey(

  credential.secretAccessKey,

  dateIsoString(new Date()),

  region_name,

  's3'

);

const signature = await jsAwsSigv4.getSignature(

  signingKey,

  'stringToSign'

);

```

## Get pre-signed URL

```javascript

const uriPath = '/public/test.txt';

const headers = {'Content-Type' : 'application/json', 'X-Amz-Meta-Foo': 'barbaz', 'X-Amz-Meta-Foobar': 'bazbaz'};

const signedUrlGet = await jsAwsSigv4.getSignedUrl(

  {

    accessKeyId: credential.accessKeyId,

    secretAccessKey: credential.secretAccessKey,

    sessionToken: credential.sessionToken, // optional

    regionName: region_name

  },

  {

    method: 'GET',

    hostName: host_name,

    serviceName: 's3',

    uriPath,

    headers // optional

  },

);

```
