Building Web Applications with Rocket for Rust

In this tutorial, we’ll explore how to build a web application using the Rocket web framework for the Rust programming language. Rocket is a fast, type-safe, and easy-to-use framework that allows us to build web applications quickly, leveraging the power and safety of the Rust language.

Setting up the Environment

Before we start, make sure you have the following prerequisites installed:

• Rust: You can install Rust using rustup by following the instructions on the official Rust website.
• Cargo: Cargo is the Rust package manager, and it is included in the Rust installation.

Creating a New Project

To create a new Rocket project, we’ll first create a new Rust binary project using Cargo. Open a terminal and run the following command:

cargo new rocket_example --bin

This command creates a new binary project named rocket_example. Change into the project directory using:

cd rocket_example

Adding Dependencies

To use Rocket, we need to add it as a dependency in our Cargo.toml file. Open Cargo.toml and add the following lines under [dependencies]:
