Build API-driven modern applications!
APIs are similar to the user interfaces, with the only difference is that a user is a machine or software.
We all have heard the term called API first design or just API’s. Actually, the term API first design became popular after the industry started mentioning the term cloud-native application. Over a period of time from the development of a monolithic application, programmers started breaking down these applications into microservices.
All the interactions with these microservices from Web, Android, or iOS devices need to happen through APIs. Therefore, design for these APIs plays a major role in providing data to these interfaces. This means microservices have only one medium to communicate that is nothing but APIs.
Thus API first design principle comes here into the picture. We need to consider designing our API first in mind before even writing the implementation for our microservices/backend services.
Remember: APIs are business drivers, so develop it at the beginning of the development of a system.
In the API-first design approach, an API is considered as a First-class citizen. Summarizing the above statements will give us the below three key points, which can be taken as a principle of API first approach.
- API is the first user interface of our application.
- API comes first and then the application.
- API is described (and maybe even self-descriptive)
There are plenty of companies using API first approaches, such as Twillio, NETFLIX, Stripe, Algolia, SendGrid, Etsy, Adobe, Amazon, and many more.
Amazon was among the first company which instructed its employees to use this approach. This approach’s importance could be understood with an incidence when Jeff Bezos(CEO of Amazon) issued a mandate called(sometime back around 2002), with a warning anyone who doesn’t follow this process will be fired.
Benefits of API-first approach
The following are some of them.
- Reusable/composable enterprise
- Allows parallel development
- Reduces overall cost over the lifetime of the project.
- Reduces risk of failures
- Faster growth
- Freedom from constraints
Now let’s explore one of the powerful languages of the web, which helps us implement the above-discussed approach.
Also, it does not require to be compiled, unlike C, C++, and Java.
Is it limited to the client-side?
An example of such a framework is NodeJs.

is optimized for building semantically correct RESTful web services ready for production use at scale. When it says semantically correct, it means staying true to the spec, which was one of the Restify project team’s foremost goals.
It optimizes for introspection and performance and is used in most of the largest Node.js deployments. One of the coolest features of Restify is that it automatically creates DTrace probes for you whenever you add a new route/handler. There are actually three separate clients shipped in Restify:
- JsonClient: sends and expects application/json
- StringClient: sends the URL-encoded request and expects text/plain
- HttpClient: thin wrapper over node’s HTTP/HTTPS libraries
The detailed development guide could be found.
Restify is used by some of the industry’s most respected companies like Netflix, Joyent, Pinterest to power some of the largest deployments.
is a project of the .
Due to its robustness, many popular frameworks(such as Feathers, Kraken, Sails, Kites, NestJs, etc.) are based on Express. It is a minimal and flexible node.js based web application framework that provides a robust set of features for web and mobile applications.
Since it provides a layer on top of, we can efficiently access the. It is suitable for writing applications with server rendering because it supports many template engines (such as pug and handlebars). For API development, it contains intermediate handlers and many HTTP service/utility methods.
is an MVC framework build under the Sails company headquartered in Austin, TX. It was developed by Mike McNeil to assist his team in building scalable Node.js projects for startup and en
terprise customers. Since its release in 2012, Sails has become one of the most widely-used web application frameworks globally.
It is a lightweight that sits on top of Express. It is compatible with any front-end: Angular, React, iOS, Android. Sails claim to get integrated with any database through its powerful ORM called Waterline. It uses Express for handling HTTP requests and wraps socket.io for managing WebSockets.
is a multi-transport API Server with integrated cluster capabilities and delayed tasks. The goal of Actionhero is to create an easy-to-use toolkit for making reusable & scalable APIs for HTTP, WebSockets, and more. It was built from the ground up to include all the features we expect from a modern API framework.
The type of workload Actionhero excels at involves producing and consuming APIs, storing and retrieving data from databases, modifying files, and similar jobs.
Actionhero has 5 key concepts that make up each application: Actions, Tasks, Initializers, Chat, and Servers.
is a highly extensible, open-source Node.js and TypeScript framework based on Express. It allows us to quickly create APIs and microservices composed of backend systems such as databases and SOAP or REST services.
It is a new, improved programming model with Dependency Injection and new concepts such as Components, Mixins, Repositories, etc., which make this the most extensible. LoopBack allows us to create a GraphQL interface for any REST API using OpenAPI-to-GraphQL.
We can get started with Loopback in no time by just following its steps in. Their documentation is categorized based on four quadrants, and those are,
- Learning-oriented: Tutorials provide hands-on lessons where users can learn the framework by doing.
- Problem-oriented: How-to Guides provide recipes to solve specific goals you may encounter while building a LoopBack project.
- Understanding-oriented: Concepts pages explain architecture concepts, wider view, and deeper knowledge about the framework.
- Information-oriented: Reference guides provide a technical description of the machinery and how to use it.
Companies like GoDaddy, Symantec, Sapient, Fundrails, ShoppinPal, and WhiteBoard are using LoopBack extensively.
is a set of tools and an architecture pattern that make it easy to create scalable REST APIs and real-time applications. We can build prototypes in minutes and production-ready apps in days. Feathers can interact with any back-end technology, support over a dozen databases, and work with any front-end technology like React, VueJS, Angular, React Native, Android, or iOS.
To get started with the first Feathers application, follow the. If you are stuck or have a question, you can get help on their different channels, including Slack, GitHub, StackOverflow, Telegram, etc.
The team behind Express designs koa. It aims to be a smaller, more expressive, and robust foundation for web applications and APIs. Koa does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable.
By leveraging async functions, Koa allows us to ditch callbacks and greatly increase error-handling. Get it started in three commands as below.
$ nvm install 7$ npm i koa$ node my-koa-app.js
is a Node.js MVC framework that is maintained and backed by a vibrant community. It offers a stable ecosystem to write server-sid applications so you can focus on business needs over finalizing which package to choose or not. It is like any other npm module with some code on top to work smoothly with AdonisJs applications.
In case of any queries or bugs, one can communicate with the AdonisJs team through the below channels.
- : Share bugs or create feature requests
- : Ask questions, showcase your project, and participate in the life of the AdonisJs Framework.
- : Join the Discord server to chat instantly with others in the community.
- : Stay in touch with the progress made each day and be informed about awesome projects provided by the community.
Both parts were written from scratch.
