Packaging a Gleam app into a single executable

Introduction to Gleam

As a developer, I'm always on the lookout for new and exciting programming languages to add to my toolkit. One language that has caught my attention recently is Gleam. With its focus on simplicity, performance, and concurrency, Gleam has the potential to be a game-changer for building scalable and efficient applications. However, one of the challenges of working with Gleam is packaging and distributing applications. In this post, we'll explore how to package a Gleam app into a single executable.

Why this matters

Packaging a Gleam app into a single executable is important for several reasons. Firstly, it makes it easier to distribute and deploy applications, as users don't need to worry about installing dependencies or setting up their environment. Secondly, it improves security, as the executable can be digitally signed and verified, ensuring that the application hasn't been tampered with. Finally, it simplifies the development process, as developers can focus on writing code rather than worrying about packaging and deployment.

How to install Gleam

Before we dive into packaging a Gleam app, let's cover the basics of installing Gleam. To get started with Gleam, you'll need to have the following installed on your system:

• Rust: Gleam is built on top of Rust, so you'll need to have Rust installed on your system.
• Gleam: Once you have Rust installed, you can install Gleam using the following command:

cargo install gleam

Packaging a Gleam app

Now that we have Gleam installed, let's talk about packaging a Gleam app into a single executable. To do this, we'll use the gleam build command, which will compile our Gleam code into a binary executable. Here's an example of how to use the gleam build command:

gleam build --target executable

This will create a binary executable in the target directory, which can be run directly without needing to install any dependencies.

Features of the Gleam executable

The Gleam executable has several features that make it useful for building and deploying applications. Some of the key features include:

• Static linking: The Gleam executable is statically linked, which means that all dependencies are included in the executable itself, making it easy to distribute and deploy.
• Cross-compilation: Gleam supports cross-compilation, which means that you can build executables for different platforms (e.g. Linux, Windows, macOS) from a single codebase.
• Small binary size: The Gleam executable has a small binary size, making it easy to distribute and deploy, even over slow networks.

Verdict

So, who is this for? If you're a developer looking to build scalable and efficient applications, Gleam is definitely worth checking out. With its focus on simplicity, performance, and concurrency, Gleam has the potential to be a game-changer for building modern applications. And with the ability to package a Gleam app into a single executable, you can easily distribute and deploy your applications to users.
