Rust Web Programming - Second Edition

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Getting our application running with Redis

Running our application with Redis locally will require us to use Redis with Docker, export the APP_TYPE environment variable as "worker", and then run our application with Cargo. For our Redis, our docker-compose.yml file takes the following form:

version: "3.7"
services:
    redis:
      container_name: 'queue-redis'
      image: 'redis'
      ports:
        - '6379:6379'

We can then export our APP_TYPE environment variable with the following command:

export APP_TYPE=worker

We can then run our application with the following command:

cargo run

When we run our application, we will get the following printout:

IncomingBody { one: "one", two: 2 }
IncomingBody { one: "one", two: 2 }
IncomingBody { one...
