Use Cases

Configuration

A common use case for embedded scripting languages is to make an application dynamically configurable, without the need for a recompile. In this case, an embedded scripting language can provide a way to load and run configuration scripts at runtime.

Hot-reloading and Modularity

In large applications, being able to dynamically load, execute, and unload scripts while the application is still running can lead to more modular code and a faster development cycle. Risor can offer a flexible way to achieve this.

End-User Scripting

If you want to provide a way for users to customize your application's behavior or extend its functionality, Risor can be a good choice. Setups like this are seen in many video games and software tools that provide APIs for modders and plugin creators.

Prototyping

Risor can be used for quick prototyping within your Go application. Thanks to streamlined syntax and faster development cycles, this can be a great way to implement a first version of new features. Later, if the feature is well-received, the Risor code can be easily transformed into raw Go as needed.

Interacting with Different Environments

Risor is convenient for working with different environments like OS commands, web APIs, and databases. Because Risor has excellent libraries built-in, you can jump right to the interesting work without spending time researching third party libraries.

Glue Code

Scripting languages are often used as "glue code". Risor is handy for stitching together different systems due to its lightweight nature. Running a Risor script (instead of compiling a Go binary) is great for small integration tasks to support a larger application written in Go.
