Teeny-tiny library for signing requests to Amazon Web Services using thesignature v4 signing algorithm. Supports signing requests viaAuthorization header or query params.
No serious, it's really small!
I wanted something small. Really, really small. Couldn't find a small AWS v4 signing library that worked in a browser using rollup for bundling so... here we are. ¯\_(ツ)_/¯

Supports query params, date overrides viaX-Amz-Date orDate headers, multiple header values, and probably some other features.
Tested against API Gateway so far. Your results may vary for other services, S3 seems especially fraught with peril. 💀
