If you don’t have Rust installed, follow the i nstallation guide. You need to manually write out the name and version of the dependency in the Cargo.toml, which is the equivalent of package.json.īelow is a comparison between a bare-bones Node project with npm and a Rust project with Cargo.

Unfortunately, as of the time of writing, cargo does not have a way to update dependencies automatically.

It can be updated with new dependencies from the npm registry. This is where all your dependencies live. When you initiate a Node project with npm init, you get a package.json. you’ll already be familiar with npm as the package management and registry. If you’re coming from a Node.js background.

Now let’s get started! Setup and important conceptsįirst, let’s go over how to set up a basic Rust project, folder structures, dependencies, etc. To paint a clearer picture, I’ll compare it to Node.js throughout the article. I’ve written this guide to be easily understood by anyone with a basic understanding of the Rust language. You must at least understand the concept of CRUD. To proceed with this tutorial, you’ll need a basic understanding of API development. This will be a bare-bones project designed to demonstrate all the fundamental building blocks for writing APIs in Rust. We’ll create all the CRUD API endpoints for employee management applications. Our persistence layer will consist of Postgres with Diesel as the ORM and query builder.īefore we dive into coding, let’s take establish what we’ll be building and some fundamental requirements and assumptions. Other popular alternatives include Rocket and Tower. I chose the Actix web 2.0 framework because it’s one of the most popular, has great documentation, and uses patterns similar to TypeScript Express in Node.js. In this tutorial, we’ll demonstrate how to write simple endpoints, handle errors, maintain a connection to the database, persist data to Postgres DB, and, eventually, handle the request-response cycle. I personally prefer Rust because it is simple, strongly typed, extremely fast, and safer than almost any language out there. There are quite a few frameworks that make it easy to create a REST API by reducing the number of boilerplates.
