Readings: Express REST API
In this Read: 03, I will talk about those topics:
- Review, Research, and Discussion.
- Vocabulary Terms.
- Preparation.
Review, Research, and Discussion
- Name 3 real world use cases where you’d want to change the request with custom middleware
- Translator.
- Accumulating-Duplicating Data.
- API Security.

- True or false: The route handler is middleware?
- In Express, there is no hard and fast distinction between the two. Someone would generally call something middleware that examines a bunch of different requests and usually prepares the request for further processing. Someone would generally call something a route handler that is targeted at a specific URL (or type of URL) and whose main purpose is to send a response back to the client for that URL.

- At what point in the request lifecycle can you “inject” middleware?
- any point of the request life cycle.

- What can cause express to error with “Request headers sent twice, cannot start a second response”
- Soap;SOAP provides the following advantages when compared to REST:
- ٍSending response twice. So, you are getting the error second time because the the response is already send.

Vocabulary Terms
- Middleware
- Middleware is software that bridges gaps between other applications, tools, and databases in order to provide unified services to users.

- Request Object
- The request object allows you to submit a POST or GET request to an URL. Essentially it provides a way to make REST API requests to another URL. An example scenario is if you need to submit form information to a 3rd party as well as save it within the CMS.

- Response Object
- It is the object which communicates between the server and the output which is sent to the client.

- Test Driven Development
- Test Driven Development (TDD) is software development approach in which test cases are developed to specify and validate what the code will do. In simple terms, test cases for each functionality are created and tested first and if the test fails then the new code is written in order to pass the test and making code simple and bug-free.

- Behavioral Testing
- Behavioural Testing is a testing of the external behaviour of the program, also known as black box testing. It is usually a functional testing.

Preparation
- Classes
- Classes are a template for creating objects. They encapsulate data with code to work on that data. Classes in JS are built on prototypes but also have some syntax and semantics that are not shared with ES5 class-like semantics. Classes are in fact “special functions”, and just as you can define function expressions and function declarations, the class syntax has two components: class expressions and class declarations.

- Routing
- Routing refers to how an application’s endpoints (URIs) respond to client requests. For an introduction to routing, see Basic routing.
You define routing using methods of the Express app object that correspond to HTTP methods; for example, app.get() to handle GET requests and app.post to handle POST requests. For a full list, see app.METHOD. You can also use app.all() to handle all HTTP methods and app.use() to specify middleware as the callback function (See Using middleware for details).For further information clicks =>[here]https://expressjs.com/en/guide/routing.html)
