Building a Node.js service using the API-first approach

Building a Node.js service using the API-first approach

Nowadays technology companies are adopting the API as one of the most valuable pieces of their business.

What does it mean when we talk about API-first development? We already know the benefits of using an API-first approach:

  • Reduced interdependencies
  • Earlier validation
  • Early feedback with the freedom to change
  • Improved efficiency

This article describes what it means to use the API-first design approach. It also walks through an example of using this approach with the OpenAPI Specification and with oas-tools as the Node.js back-end application, which enables you to care only about the business logic. All the validation of incoming requests are done by the oas-tools library (based on the OpenAPI Specification file provided).

Contract-First API Design with Apicurio and Red Hat Fuse/Camel

Contract-First API Design with Apicurio and Red Hat Fuse/Camel

This is part one of my two-article series that demonstrates how to implement contract-first API design using Apicurio and Red Hat Fuse.  It covers how to create an OpenAPI standard document as the contract between API providers and consumers using Apicurio Studio. It also shows how to quickly create mock tests using Red Hat Fuse which is based on Camel.

There are two common approaches when it comes to creating APIs:

  • Code first (top-down)
  • Contract first (bottom-up)
