Microservices

Syndicate content 6 

In my previous posting about the new support in QEWD for JSON Web Token (JWT) support, I mentioned that it was a key step in enabling Micro-Service support in QEWD.  In this post I'll give some background to how they work and the thinking behind them.

If you haven't heard about Micro-Services and/or want to learn more, there's lots of information available if you do a Google Search.  Here's a good starting point:

If you read my previous post that introduced QEWD Micro-Services, you're hopefully eager to learn how to use them.  So in this post I'll explain what you need to know in order to get started.

If you look in the QEWD repository, you'll find the folder:

In my earlier post on JSON Web Tokens (JWTs) and QEWD I used this example application to explain how to use JWTs.  This example application also demonstrates how to set up a simple Micro-Service, in this case a service that handles user authentication.  So let me now delve into that aspect of the example application.

If you're wanting to use QEWD Micro-Services, you must also use JWTs - these provide the means by which the user's authentication and session can be cross-communicated and handled by multiple, discrete QEWD servers.  So, take a look at the startup file
