Best practice for storing server endpoint configurations for static web application

We are hosting our Angular based static web application on AWS S3. This web application tries to access AWS Lambda based backend via APIGateway or directly access using AWS Javascript SDK.

What is the best practice to accomplish this?, storing endpoints in Dynamodb table and accessing […]

Deploy Java backend and angularjs frontend to elastic beanstalk

Website not updating content and files deployed on AWS

I have an angularjs website Hosted at AWS Elastic Beanstalk. Earlier website had a HTML smart table grid. which we later replaced it with simple table with ng-repeat. For pagination dirpagination.js is used. https://github.com/michaelbromley/angularUtils/tree/master/src/directives/pagination Everything works fine locally. But when deployed on AWS environment content doesn’t get updated . sometimes Network tab (browser) shows dirpagination cannot be found, while sometimes it loads. Any help would be grateful.
