RSX: Package Risor Scripts into Go Binaries

rsx is a tool that packages your Risor scripts into a standalone Go binary, allowing for easy distribution of your applications without dependencies.

Note

RSX is currently in beta.

Features

• Package Risor scripts into a single executable
• Built-in Risor modules for additional functionality
  • Worker pool
  • RSX
• Easy project initialization and management
• Built-in SQLite support with FTS5
• Ability to external Risor native modules:

import rsx

rsx.load("gh:rubiojr/risor-libs/lib/test", { branch: "main" })

• Additional Risor Go modules included:
  • sched: Schedule tasks

Pre-requisites

You need to have Go installed on your system. If you don't have it, you can download it from the official website.

Installation

Install RSX using Go:

go install --tags fts5 github.com/rubiojr/rsx@latest

Ensure that your Go bin directory is in your PATH.

Quick Start

1. Create a new Risor project:

   rsx new myapp
   cd myapp

2. Edit the main script (main.risor) to add your code:

   import rsx
   
   rsx.log("Hello from Risor!")
   

3. Build the Go binary:

   rsx build

Note

rbx runs go build under the hood, so you can pass any additional environment variables to it, like GOOS, GOARCH, etc.

4. Run your application:

   ./myapp
   # Output: Hello from Risor!

Project Structure

• main.risor: The entry point of your application.
• lib/: Directory for additional Risor modules.

Adding custom Risor modules

Place any additional .risor files in the lib directory. They will be automatically available at runtime.

Adding custom Risor Go modules

External Risor Go modules are supported. To add a custom Go module, follow these steps:

Add a .modules file in the root of your project with the following format:

github.com/rubiojr/risor-modules/hello
github.com/rubiojr/risor-modules/onemore

Where each line is the Go module path used in a Go import statement.

Then, run rsx build to build the binary with the custom module.

Risor Go modules are regular Go modules that extend Risor functionality with new built-ins, like https://github.com/rubiojr/risor-modules/hello.

See related official documentation at https://risor.io/docs/contributing_modules.

The RSX Module

RSX comes with a built-in rsx module providing basic functionality. For available functions, refer to rsx.risor.

Development Workflow

During development, you can run your Risor scripts directly:

# needs main.risor as the main entry point
rsx run

Or you can use eval also:

rsx eval main.risor

This allows for faster iteration without needing to rebuild the binary.

Note

Custom native Go modules not built into RSX are not avaible with rsx run. If you are using a custom module, you will need to build the binary with rsx build to test it.

Projects using RSX

• Firefox history exporter - Firefox history to JSON exports.
