awsSignV4Apigee.js is a Pure JavaScript implementation of AWS Signature Version 4 signing process for use with Amazon Web Services (AWS) APIs.

This is a custom implementation which uses Googles's SHA256 libraries to specifically work with Apigee Edge/Apigee X or inside a vanilla JavaScript Environment.

Just load all the files in the src folder into your project and use the awsSignV4Apigee function to sign your requests.

const signData = { request: { method: 'POST', params: "", body: encodedMessageBody }, config: { host: sqsHost, uri: sqsURI, accessKey: sqsAccessKey, secretKey: sqsSecretKey, region: sqsRegion, service: "sqs" } }; var signedHeaders = awsSignV4Apigee.createSignature(signData); console.log(signedHeaders); /* { authorization : "AWS4-HMAC-SHA256 Credential=AKIA6DAAAAWLWABC3ADC/20240305/us-east-1/sqs/aws4_request, SignedHeaders=host;x-amz-date, Signature=109301af24018edfd27e8bb182asdfdsdfdss9b98e8ac9af63c62399295fdc3d" host : "sqs.us-east-1.amazonaws.com" xAmzDate : "20240305T051902Z" } */ 

Import the proxy into your Apigee Edge or Apigee X environment and add JS resources from src directory and test.

Note: The implementation uses the var keyword for defining variables. If you are using this in a modern environment, you can replace var with let or const as per your requirement. I have used var for compatibility with Apigee environment.
