AWS Lambda With NestJS

Greg Emerick AWS, JavaScript, Node, Technology Snapshot Leave a Comment

In my previous blog post, I showed running a Spring Boot Java application in AWS Lambda. I discussed the pros and cons of using Java and Spring with Lambda. In this blog post, I’ll cover another Lambda option with NestJS. NestJS provides a framework that is not too different from a typical Spring application. It also addresses some of the negatives of using Java and Spring in a Lambda function.

To recap, AWS Lambda provides low cost compute with zero maintenance. Lambda runs your code on demand, without provisioned and managed servers. Lambda automatically runs and scales your code. You are charged for every 100ms your code executes and the number of times your code is triggered. Lambda has clear cost and maintenance benefits over typical on-premise or EC2 deployments. What does it take to run a Nest application as a Lambda? Does NestJS provide benefits over a Java Spring application?

Part 5: Div​ing into the Vue.js SPA

Part 5 of the Solid Foundations Learning Series
This is an in-depth learning series focused on a specific application: a JavaScript-based suite of single-page applications optimized for use in a microservice environment. We focus on telling the story of “why” and “how” it was built.

 —

In Part 4 of this series, we learned the why and how of adding single-page applications to our server-rendered application. In this blog, we take a small step to the side and talk about our Vue.js app that is added to the reference application. We will specifically focus on how the Vue.js components are added and how the routing is completed within the SPA.

A Look Into React Hooks

Nick Brown JavaScript, React, Single-Page Application 1 Comment

There are two ways to create React components, using functions or classes. A common question when learning React is often “When do I use which?” Luckily, this is a question that might eventually become obsolete with the release of React version 16.8 as it includes hooks.

Hooks provide a way to use functionality such as state and context that could only be achieved through classes previously to be easily done with functional components.

In this blog, we’ll introduce React hooks and show some code examples of those hooks in action. Specifically, we will take a simple class component and convert it to a function with hooks, have an in-depth look at hooks useState and useEffect, and create a custom hook. Let’s get started!

Part 4: Adding Smaller SPAs to An Existing Application

Chris Berry JavaScript, Node, Single-Page Application, Tutorial, Vue Leave a Comment

In our prior segments of this series, we addressed being able to add in pages to the application and have them automatically registered with the navigation. We also discussed having Markdown content associated with different pages of the application.

In this segment, we will talk about the philosophy of using smaller single-page applications in place of large ones. We’ll discuss how to add in a single-page application to this application. And we will dive into a couple of the example single-page applications and talk about how they were built specifically….

Part 2: Navigation​ Setup with Node + Express ​

This is an in-depth learning series focused on a specific application: a JavaScript-based suite of single-page applications optimized for use in a microservice environment. We focus on telling the story of “why” and “how” it was built.

In part one, we reviewed how the base application was created by using the Express Generator command line tool. We also reviewed the folder layout, look and feel, and an overview of what each section of the application does. In this post, we’re going to dive in a little deeper to the application and explain the why and how of the navigation setup for this application….
