It’s really time-consuming running iterations and tinkering with APIs over and over. We have to continually tweak stuff to make things aligned with our expectations. We are aware that in the first iteration of code design, things are never perfect.

1.1.1 Be accurate about your APIs the first time Let’s look into some of the features of Swagger. This saves us quite some code refactorization time at later stages. Helps us keep track of things that should ideally be implemented when designing APIs from the bare bones. It standardizes the whole process of writing APIs. We try to get an idea of the standards being complied to. We have to go through a bunch of articles online and docs of API implemented by existing scalable systems like Twitter, Facebook, etc. Typically, when writing an API from scratch. I would just base my design on that and would be carefree.

How helpful it would have been had there been a global specification for writing APIs. Am I handling the errors correctly or am I missing something? Are all the safety and data quarantine checks in place? What else… What about the design? Seems Ok to me. When writing APIs from scratch, the thoughts that pop up in our minds as a developer are: Am I doing it right? I mean I have included the versioning system in the API. How does Swagger fit in here? 1.1 How does Swagger help in implementing APIs? Businesses can’t afford any loopholes or glitches in the functionality of the APIs after all the entire communication depends on them. The whole design of microservices architecture is laid on APIs. In today’s software realm, there are hardly any systems running online that do not expose an API. It simplifies the process of writing APIs starkly, specifying the standards and providing the tools required to write robust, secure, performant and scalable APIs. Swagger is a set of open-source tools for writing REST-based APIs. So, without any further ado! Let’s get started. This write-up will answer all your queries on it like what is Swagger? Why do we need it when writing REST-based APIs? What is OpenAPI? How are Swagger and OpenAPI related? What are the differences between them, If any? Is there any specification or any global standard for writing REST APIs and so on? This article is a comprehensive write-up on Swagger which is a suite of tools for building REST APIs.
