Teeny-tiny library for signing requests to Amazon Web Services using the signature v4 signing algorithm.
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. ยฏ\_(ใ)_/ยฏ
import sign from "aws-sig";
const config = {
accessKeyId : "AKIDEXAMPLE",
secretAccessKey : "wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY",
// sessionTokens are optional, but correctly supported
sessionToken : "..."
};
const request = {
// These can be part of the config object or the request object
region : "us-east-1",
service : "service",
method : "GET",
url : "https://my.aws.url.that.i.need.to.hit/look/it-has/a-path-in-it-as-well",
// Headers are optional
headers : {
// Single header value
"X-Amz-Date" : "20150830T123600Z",
// Multiple headers
"X-Multiple" : [ "one", "two", "three" ]
}
// Body is optional, should be a string
body : "..."
};
const signed = sign(request, config);Supports query params, date overrides via X-Amz-Date or Date 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. ๐
