Rocket is a popular framework for Rust backend web development like the Actix Web framework. Getting familiar with the Rocket framework

This command will download and build the dependency crates and compile the project. Now, build the project to be certain there are no errors: cargo build

In the Cargo.toml file, add the SQLite crate in the dependencies section: Next, let’s populate the user table with values: insert into users(username, password) values ("Jon Doe", "j0hnd03") tables command, we’ll see that users is now a table in the database engine:

Next, we’ll create a table containing usernames and passwords: create table users(username text PRIMARY KEY, password text) Create a folder called data using the below command and navigate into it: sqlite filename.db To start, run an instance of SQLite in the terminal with the following command: sqlite3 Now, let’s connect to the SQLite database. Connecting to the SQLite database with Rust

If you’re not familiar with how to use the SQLite3 database, you can learn more about it here. Now, confirm installation, like so: sqlite3 -version

Here’s the installation command for Linux users: sudo apt install sqlite3 SQLite is pre-installed on new Mac computers, but (if needed) the Mac command is as follows: brew install sqlite

SQLite is the default database store in this tutorial, so as a next step, install the SQLite drivers for your machine. For our SQLite API project, we’ll use the following command for initialization: cargo new rust-rocket-sqlite-api -bin Initializing the project with CargoĬargo makes it easier to start a Rust project of any kind. As lightweight and “pruned” as it sounds, it has most of the important query language features in the SQL2 standards. SQLite transactions are ACID-compliant (atomic, consistent, isolated, and durable), providing safe access to multi-threading operations. Because SQLite is literally a database residing in a single cross-platform file, it requires no administration. It is serverless and requires zero configurations. SQLite is a relational database management system with a lightweight feel in terms of setup complexity and resource usage. Ability to start a development project in your preferred environment.Basic understanding of database connections.Familiarity with the Rust programming language and Cargo build system and package manager.

To follow along with this tutorial, you’ll need the following:

Getting familiar with the Diesel framework.

Getting familiar with the Rocket framework.

Connecting to the SQLite database with Rust.

We’ll create a SQLite database, set up and install the Rocket framework for writing the server logic, and then use the Diesel framework to handle connections to the SQLite database. This tutorial will demonstrate how to use SQLite as the database context system for Rust APIs. SQLite and Rust will provide you with speed and efficiency. Whether you’re using SQLite because it is the most popular database engine in the world, or you’re working with Rust because it is the most loved language, you can never go wrong with these two technologies. Create an API in Rust with SQLite and Rocket A fanatic for technical writing and open source contribution. These certificates are saved locally on your machine in the ~/.plotly/connector folder.MacBobby Chibuzor Follow Go, Solidity, and Haskell developer interested in the cloud native world and blockchain technology. It's still just loading content from your localhost server - data is not traveling over the network! And remember, this domain just re-routes to localhost:9495 on the global DNS network. The domain has a unique certificate associated to it. Your application will spin up a server with those certificates and the plotly chart creator web application will be able to make requests to your server, no problem! After several minutes (this authorization only needs to be completed once), you'll have a unique subdomain and a unique server. We then re-route that subdomain's DNS to localhost:9495.įor example, when you start up your app, your app will make a request to this certificate and domain issuing server. What we've done is created a server which generates a unique subdomain and a unique Let's Encrypt SSL certificates for that subdomain. Let's Encrypt is service for offering free SSL certificates. In version 2.0+, the app will now automatically generate an SSL.
