In my recent YouTube video, I dive into Gleam, the statically-typed functional programming language that’s making waves in the dev community. If you’re tired of runtime errors and looking for a language that blends the power of the BEAM VM with clean, reliable code, Gleam might be your next go-to tool.

Here’s a breakdown of the key points from the video, explaining why Gleam is such a game-changer for backend developers.

1. Why Gleam?

Gleam is a general-purpose, statically-typed functional language built on the BEAM VM, which also powers Elixir and Erlang. What makes it stand out is its focus on:

• Minimal Syntax: Gleam’s syntax is clean and easy to learn, making the onboarding process much smoother.
• Static Typing: Unlike Elixir and Erlang, Gleam’s static typing helps catch bugs before runtime, reducing the headache of runtime errors.

2. Compiler: Blazing Fast & Helpful Error Messages

Gleam’s compiler is not only blazing fast but also gives you helpful error messages that are clear and concise. No more cryptic error logs that leave you confused for hours.

• It’s like having a friend that not only points out what’s wrong but also tells you exactly how to fix it. This improves developer productivity and keeps the workflow smooth.

3. Fault Tolerance & Reliability

One of the biggest perks of Gleam is its focus on fault tolerance. Running on the BEAM VM means you inherit the incredible fault-tolerant nature of Erlang and Elixir.

• Combine that with static typing and you get a system that is highly resilient to crashes and bugs. Almost zero runtime exceptions and no null values make for incredibly reliable backend code.

4. Tooling: Productivity Out of the Box

Gleam comes with everything you need to get started right away:

• Built-in formatter: Automatically formats your code, so you don’t have to worry about style consistency.
• Package management: Makes it easy to manage dependencies and build projects efficiently.

This complete package means you spend more time building and less time setting up tools.

5. Documentation and Community

Gleam’s documentation is top-notch. Every function is well-documented with examples, making it easy to learn as you go. The Gleam community is also incredibly welcoming and inclusive, encouraging collaboration and growth for both new and experienced developers alike.

6. JavaScript and TypeScript Compatibility

If you’re working in the JavaScript ecosystem, Gleam fits right in. It can compile to JavaScript and even generates TypeScript definitions, making it extremely useful for integrating into existing projects. This flexibility ensures you’re not locked into one ecosystem and can take advantage of Gleam wherever you need it.

Conclusion

Whether you're a backend developer looking for more reliability or someone seeking to dive into functional programming with less hassle, Gleam has the potential to make a big impact.
