We all have a pretty good idea about APIs and their role in integrating applications and revolutionizing the way we view connectivity. API-led connectivity and integration have made global businesses possible and has made products and services accessible on a scale that was once inconceivable.
But there’s a lot more to APIs than a general overview. One of the things that make APIs so fast and agile and convenient for developers are API fragments. Reusable APIs and API fragments are basically vital for saving time and resources in any sort of tech-based organization.
Intrigued? Let’s take a quick peek at API fragments and why they are necessary.
What Are API Fragments?
To understand API fragments, we first need to grasp the idea of an API specification. This is because an API fragment is a part of an API specification. An API specification is a design of how your API should look structurally. In other words, it is the skeleton of your API.
The API spec mentions what an API does and the sort of call and response you can expect from it. It is a major component of your API’s development since it helps you identify design flaws and errors before you write a line of code.
A great way to efficiently create APIs is to reuse portions or fragments of APIs into specifications. An API fragment is a RAML document which has a version and an identifier. However, the fragment itself isn’t a complete RAML specification. These fragments can be data types, traits, resource categories, and many others.
Both reusable APIs and API fragments are a great way to handle understaffed IT firms, especially if there are lots of unfinished projects and resources that are stretched thin. Developers won’t have to create entirely new projects from the beginning and can recycle and reuse APIs and their fragments to speed things up greatly.
The ability to reuse functionality of an API for various applications, instead of building a new one whenever a new application needs to be integrated or when a new functionality introduced can save your time and your organization’s resources by a long shot. They are also very useful when building an infrastructure that has been designed to change and get upgrades down the road.
When creating an API, you might realize that certain bits or fragments of an API specification are likely to be reused in the future. If you make a catalog of these fragments, you then have many fragments for potential reuse. This, in turn, will accelerate the speed of building your API.
Why Are They Necessary?
Having an arsenal of reusable APIs will remove the need to spend lots of time creating customized point-to-point integration. On the same note, having API fragments you can reuse will help you design and build APIs effortlessly and, in less time, than before. Also, as you design your API, you too can save the fragments so that your fellow developers can use them as well when needed.
Building an API specification out of reusable API fragments is also helpful because it creates a trend of consistency. The consistency of definitions decreases the amount of effort when implementing APIs. For instance, when a certain function is defined the same way across all APIs, you won’t have to change that function when it is reused in several other services. Once this efficiency is extended across all fragments and specifications, you remove the bulk of transformation work needed. Eventually, this will drastically reduce the time and effort needed to deliver projects.
For example, when creating an API for retail services, there will be several fragments in your specs. They can range from a Customer Name fragment, Customer Address fragment, Purchase History fragment to a Transaction ID fragment. All these fragments are used very often in retail and service-related APIs, as well as in other industries as well. As a result, they can be easily reused and repurposed when creating a new API for a different use.
In a Nutshell
API fragments are reusable components that you can create and publish to be utilized in various APIs in your business organization. Also, you can even have fragments within your API specification to increase the flexibility of your API specification.
These fragments, together with reusable APIs can save you lots of time and energy when building an API. Instead of creating every element of the spec from scratch, the fragments let you reuse parts of specifications, which gets the job done a lot faster. This in turn can help decide on your API ecosystem strategy in clearer terms and manage the API you created more easily as well.
