Chrome/Firefox WebExtension for enabling AWS resource access via Sigv4

AWS Agent

Allows your browser to access resources that require AWS Sigv4 signatures.

Inspired by carsales/aws-request-signer.

Compiling

Preferably, you should use npm >= 5.7.1 so you can use npm ci. This ensures you have the exact same files (and is much faster). Otherwise, install with npm i.

npm ci
npm run package

Main differences from carsales/aws-request-signer:

• They basically rolled their own signature process vs I rely on mhart's excellent libraries. In Firefox (and presumably elsewhere) I use mhart/aws4fetch to handle all heavy lifting. This has the perk of using the browser's WebCrypto API, which should be insanely faster. In Chrome I use mhart/aws4 because Chrome still has zero async support for webRequest.onBeforeSendHeaders.
• This extension triggers on all AWS services instead of filtering for one.
• Instance Profile credentials aren't supported as I have no use for them but could be added fairly trivially.
• Chrome/Firefox/Opera support.
