Express.js

Welcome.

What's Express?

Express provides a minimal interface to build our applications. It provides us the tools that are required to build our app. It is flexible as there are numerous modules available on npm, which can be directly plugged into Express.

Why we are using Express?

Unlike its competitors like Rails and Django, which have an opinionated way of building applications, Express has no "best way" to do something. It is very flexible and pluggable.

Pug

Pug (earlier known as Jade) is a terse language for writing HTML templates. It −

• Produces HTML
• Supports dynamic code
• Supports reusability (DRY)

It is one of the most popular template language used with Express.

What is api testing? 

API testing is a type of software testing that involves testing application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security.

Json 02

Welcome.

JSON syntax is derived from JavaScript object notation syntax:

• Data is in name/value pairs
• Data is separated by commas
• Curly braces hold objects
• Square brackets hold arrays

Both JSON and XML can be used to receive data from a web server.

JSON is Like XML Because

• Both JSON and XML are "self describing" (human readable)
• Both JSON and XML are hierarchical (values within values)
• Both JSON and XML can be parsed and used by lots of programming languages
• Both JSON and XML can be fetched with an XMLHttpRequest

---

JSON is Unlike XML Because

• JSON doesn't use end tag
• JSON is shorter
• JSON is quicker to read and write
• JSON can use arrays

Using XML

• Fetch an XML document
• Use the XML DOM to loop through the document
• Extract values and store in variables

Using JSON

• Fetch a JSON string
• JSON.Parse the JSON string
