How to debug service layer, custom handlers – Cloud Application Programming Model

Github repository:

To be published soon…

Introduction:

In this session, we will look at how to debug the service layer by accessing the _req object
Also, we will look at how we can add more complex custom handlers

Synopsis:

The generic handlers serve most CRUD operations out-of-the-box
But to add custom logic, we have to provide our own custom handlers
Also, while developing complex custom handlers, we need a way to be able to debug and set breakpoints to access the values of variables at different lines

Steps:

In this example, we will explore the contents of the _req object in our custom handler
To understand the _req object, we will take an example where the end user needs to provide the password in a custom header in order to access a protected resource
We will set debug points in our code to look into the structure of the _req object and how we can access the custom header information
Then we will also add more custom code to compare the encrypted password with the password supplied by the user before returning the protected resource

Conclusion:

This video should give you a clear idea on how to implement complex custom handlers in Cloud Application Programming Model
Also, the _req object is quite important when it comes to middleware functions. You should now be comfortable with accessing, modifying the _req object to suit your needs
