Mock RESTful Servers Fast With JSON Server

Haaris Chaudhry Technology Snapshot, Tutorial Leave a Comment

As a frontend developer, have you ever found yourself in a situation where the backend didn’t have a RESTful API that you could call to test out your user interface? Have you ever wanted to prototype an idea and found yourself getting down in the weeds setting up RESTful routes in a mock backend server?

That’s where json-server comes to the rescue!

With json-server, you simply create a JSON file that follows json-server’s conventions, and you can have a mock RESTful server up in no time. This blog post will go over the features of json-server that I have found most useful as a frontend developer.

React, The Extras.

Chris Berry JavaScript, React, Technology Snapshot, Tutorial 1 Comment

We’ve all seen and read the React tutorials. We know about classes and components and JSX and whatnot, but then there comes the time when you have to start doing things for real. “Real” you say? Yes. Like connecting to a database or navigating around something larger than “Hello World.” Oh, then there’s that dreaded state thing. Well, let’s have a quick talk about the “Extras” that we can add into a React application.

In this blog, we will address adding routing using the React Router, adding data access using the JavaScript Fetch API, and creating a global state management feature using React’s built-in Context API.

Got Formik? Yup!

Let us present this scenario. You’re building a React application, and you’ve been tasked to build a registration form. Seems simple enough, you think at first, but then you start hearing the requirements. The application needs to have validation on each field, and each field needs to have certain requirements, such as being required, being a certain type of field, having a certain length, etc. Your form must also be easily created and have an easily adjusted state during its usage. At this point, something you originally thought would be quick and easy is seeming more and more time consuming and complicated! 

Well, worry no more and look no further; the community has come to your rescue. In this post, we’re going to talk about using the form library called Formik and the validation library called Yup to build out a simple validation form inside of a ReactJS application.

Quick Look: java.util.stream Examples

Some of us take for granted the newer features in Java, but, being a software consultant, I get to be involved in projects that are sometimes constrained to older versions of Java. The features from Java 1.8 that I have enjoyed for a few years are brand new to others.

I wrote this blog as a primer for those who are just getting started using java.util.Stream classes, or for those who haven’t had a chance to take a look at them until now. The quick topics below represent just a sampling of some of the ways to be more productive using java stream classes. Rather than providing a tutorial on how the classes are used, I’ll attempt to explain by example.

Transferring Spring Batch Apps to AWS Cloud

Rik Scarborough AWS, Cloud, Spring, Spring Batch, Technology Snapshot, Tutorial Leave a Comment

The last few years have seen a lot of movement to bring applications that don’t require manual intervention from the mainframe to Unix, Linux, Windows servers, or even to the desktop. This concept is commonly known as batch programming, and Spring Batch has been the tool many of us are using to accomplish this. Another trend that is gaining steam is to move from an internally-hosted server to a cloud-hosted system.

In this post, we discuss multiple ways for transferring Spring Batch applications up to the AWS Cloud, including EC2, Docker, Lambda, and others. I concentrate on AWS in this post, but, from my experience in Google Cloud, the same ideas will apply…
