TypeScript
Last updated: Feb 10, 2026
Rationale
TypeScript is Fluid Attacks' main front-end programming language.
The main reasons why we chose it over other alternatives are:
- It is open source.
- It is a high-level programming language that is fairly easy to understand when compared to others.
- It has a big community that supports thousands of libraries, making it very flexible.
- It has a big market, allowing us to easily find developers who have worked with it previously.
- It has static typing support, which helps with maintainability, clarity and debugging.
- It is a compiled language, meaning that it requires spending extra time on compilation, but also increases source code quality by validating many things that interpreted languages do not.
- It is the most popular programming language to use along with Node.js.
Alternatives
The following languages were considered but not chosen for the following reasons:
CoffeeScript
- It has a much smaller community, making it less flexible.
- It has a small market, so finding experienced developers is way harder.
- It has been shadowed by TypeScript in recent years.
- It uses its own syntax, increasing cognitive burden on developers.
ClojureScript
- It has a much smaller community, making it less flexible.
- It has a small market, so finding experienced developers is way harder.
- It has been shadowed by TypeScript in recent years.
- It uses its own syntax, increasing cognitive burden on developers.
Usage
TypeScript is used by:
- Development documentation
- Gitlab Bot
- Platform Frontend
