Interactive REST API Documentation with Swagger UI

I am assisting a client that is migrating from a monolithic legacy application to a modern Microservice stack with Spring REST. We are helping to implement Swagger UI to provide both a front-end API UI, as well as to provide a level of documentation at the same time. This implementation has simultaneously met our project requirements, as well as garnering some positive feedback from our client!

Swagger UI is one of the most popular tools to visually render beautiful, interactive API documentation. In this blog, I’ll use a REST API application to demonstrate some usage of Swagger UI. The source project is available at https://github.com/bingliu2016/spring-boot-rest-swagger2.

Generate Strongly Typed React Components with GraphQL

Mat Warger API Development, Articles, AWS, Development Technologies & Tools, GraphQL, JavaScript, Programming 1 Comment

When developing in React, using a type system (like Typescript or Flow) can be a great help. You can be sure that your props and state are what you expect, at build-time, and code your components to match.

But what happens when you’re calling to an API to fetch some data, and the shape of that data is what really matters? Maybe the data get passed as props to a child component? You can create types for this, sure, but are they correct? Probably not! Or at least, probably not for long! Things change. Wouldn’t it be great if your types changed too?

In this post, we’re going to take a simple component from zero type awareness to fully typed, with local variables and GraphQL queries included, with a simple workflow. Grab a cup of coffee and a snack, and let’s see how this we can use GraphQL to generate type-safe components in React.

State Management with MobX and React

Nick Brown Articles, Development Technologies & Tools, JavaScript, React Leave a Comment

There are many options when it comes to managing the state of a React application. Choosing the right one for your application can feel daunting.

The most popular choice, Redux, is often thought of as verbose because it requires a lot of boilerplate code, thus slowing down development. Redux is also very opinionated so it will take time for those unfamiliar with its functional programming paradigm to become comfortable with it.

In this blog, we’ll take a closer look at an alternative that aims to solve issues in React application state: MobX. To do that, I built a simple calorie counter application that will be used to showcase MobX in use.
