Rust Web Programming

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? While most programming languages have a safety or speed trade-off, Rust provides memory safety without using a garbage collector. This means that with its low memory footprint, you can build high-performance and secure web apps with relative ease. This book will take you through each stage of the web development process, showing you how to combine Rust and modern web development principles to build supercharged web apps. You'll start with an introduction to Rust and understand how to avoid common pitfalls when migrating from traditional dynamic programming languages. The book will show you how to structure Rust code for a project that spans multiple pages and modules. Next, you'll explore the Actix Web framework and get a basic web server up and running. As you advance, you'll learn how to process JSON requests and display data from the web app via HTML, CSS, and JavaScript. You'll also be able to persist data and create RESTful services in Rust. Later, you'll build an automated deployment process for the app on an AWS EC2 instance and Docker Hub. Finally, you'll play around with some popular web frameworks in Rust and compare them. By the end of this Rust book, you'll be able to confidently create scalable and fast web applications with Rust.

Deploying our application on a server

Considering that we are now pulling images from docker hub, and that we have got our application running with NGINX and a database locally on our computer with docker-compose, it should not come as a surprise that deploying on a server merely refers to orchestrating Docker containers on a server.

As we mentioned earlier, putting our image on docker hub has enabled us to use a range of container orchestration tools such as Kubernetes and terraform. However, considering this is a simple application and the book is focused on getting a Rust web application up and running as opposed to a DevOps book, we will be using docker-compose to manage our images and containers on the server. In order to achieve this, we need to follow these steps:

  1. Create an EC2 instance on AWS.
  2. Configure traffic rules for the AWS server.
  3. Write a bash script that SSHs into the server, deploys, and then starts the application.
  4. Configure docker-compose for...
