Rust for NodeJS developers (I) - Why and how?

Working at a company that uses Node.js, Ruby, and Python is an enriching experience. Node.js offers a non-blocking I/O model and a robust ecosystem with npm, while Ruby stands out for its elegant syntax and focus on productivity. Python, on the other hand, is known for its simplicity and versatility, making rapid application development straightforward.

Despite these advantages, we are always open to exploring new technologies. Recently, Rust has caught our attention due to its high performance, memory safety and reliability.

In this series of articles, we will share the experience of learning Rust as a Node.js developer by building a GraphQL API in Rust.

Motivation

The decision to learn Rust for a NodeJS developer isn't a trivial one. However, there are compelling reasons why Rust is gaining popularity in web development, especially for web APIs and high-performance applications:

Challenges

Learning Rust presents unique challenges compared to other languages.

One of the most significant hurdles is Rust's strict ownership and borrowing system, designed to ensure memory safety without a garbage collector. This system requires a deep understanding of how data is managed and accessed, which can be initially complex for developers accustomed to more relaxed memory management in other languages.

Additionally, Rust's syntax differs significantly from these languages, requiring developers to adapt to its explicitness and pattern matching construct.

Despite these complexities, mastering Rust offers the promise of high-performance applications with robust memory safety guarantees, making the learning journey both demanding and rewarding.

Learning Rust

To embark on your Rust learning journey, we recommend leveraging the high-quality official resources provided by the Rust team itself:

In addition to the official resources, worth mentioning also:

Installing Rust

To start writing and running Rust code, you'll need to install Rust on your system. The most recommended way to do this is using Rustup, the official Rust installer. You can follow the detailed instructions on the official Rust installation page.
Once Rustup is installed, you can run the following command to install the Rust toolchain:

rustup install stable

This will install the latest stable version of the Rust toolchain, which includes the compiler, standard library, and other essential tools.

With Rustup and the toolchain installed, you're ready to embark on your Rust programming journey. Embrace the challenges and rewards of learning this powerful and versatile language, and unlock its potential for building high-performance, secure, and maintainable web applications.

Upcoming

In future articles, we'll delve into the exciting process of building a GraphQL API from scratch using Rocket + SQLx + async-graphql, seize the opportunity to explore these resources and get ready to join us as we embark on this Rust adventure together!
