REST API Design, Development & Management (Udemy.com)

PS: 

• This COURSE does NOT focus on Coding of REST API - Focus is on Designing  using proven patterns.

• Please do NOT enroll if your objective/Goal is just to learn "Coding" part of the REST API.

How was this course created?

Author (Raj) has worked with many large organizations for building their Digital Strategy in which API was a central theme. Over the years author recognized certain patterns and practices that led to successful API initiatives. Intrigued by his findings author did thorough research of 100's other successful API providers (examples: Facebook, Expedia, Capital One ...) and that resulted in a collection of Best practices and Design patterns that are covered in this course.

This course covers all the important aspects related to design, development and management of API. The best practices, design patterns, challenges, suggestions & options discussed in this course are either:

• Created by analyzing how the popular API providers such as Facebook, Twitter, Capital One etc are building and managing their API

• Taken from personal experiences of the author

Course is divided into 6 Parts:

1. Setting the stage - Discusses a case study (ACME travels) used through the course + provides information on tools used

2. Evolution of  REST API - Lectures in this section will cover the foundational concepts + Why REST/JSON has become a defacto standard

3. Designing the REST API (Covered in multiple sections)

This is where students will learn the:

• Best Practices

• Implementation patterns

To demonstrate the implementation aspects, a set of NodeJS based API is also implemented for a fictitious enterprise ACME Travels.

4. Securing the REST API

When an API is exposed by an enterprise to the public internet, it poses a risk to the enterprise as hackers may use the vulnerabilities in the API to launch attacks against the enterprise. There are multiple types of such Functional attacks that the API provider must consider. You will learn about the common attacks and the best practices for protecting the API.

5. Swagger 2.0 / Open API Initiative specifications

This section will begin with the description of Collaborative specifications development process & benefits of adopting contract first approach. At the end of this section student will be able to write Swagger/OAI specifications for their own API. As part of the lectures, a complete specification will be created for ACME Vacations. 

6. API Management

API management  is the process of publishing, documenting and overseeing application programming interfaces (APIs) in a secure, scalable environment. Lectures in this section cover the details of the following activities that an API provider carry out within the scope of API management.

APIgee, IBM API Connect & Mulesoft platforms will be used for demonstrating the various API management aspects discussed in the lectures. Students are encouraged to try out these platforms on their own to get a good feel of what API management platforms bring to table. The three platforms offer a free trial version that can be used for testing.

WHY REST API?

Today Enterprises are using REST APIs for not just building mobile applications but also for:

• Creating new channels for partnership

• Building new revenue streams & business models

• Promoting their brands

Just creating the API does not guarantee that the enterprise will be able to achieve the desired goals from API perspective. Adoption of API by developers depend on multiple aspects such as its utility, ease of use, performance, scalability, security. The API provider must apply best practices throughout the life cycle of an API.

Who should take this course?

This course is suited for any technologist interested in learning REST API from end to end perspective not just from the coding perspective. Though this course uses NodeJS for demonstrating the design best practices, it does not require students to have any prior experience wth NodeJS. 

To take this course the student is expected to know any one (or more) programming language; have understanding of web application architecture; to be familiar with the concept of services ; understands the data formats such as JSON or XML

Please note that this course will NOT teach how to code REST API in NodeJS.
