Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

SDL Verifier WebAssembly

This Rust-based WebAssembly library is forked from SDL-parser and provides a simple function to verify SDL (Schema Definition Language) text using the provided Scenario parsing and verification code. It is intended to be used in web applications for efficient client-side SDL validation.

Features

  • Validates SDL text using a Rust-based custom Scenario parser.
  • Exposes a WebAssembly function for use in web applications.
  • Optimized for small binary size and fast execution.

Prerequisites

Usage

  1. Clone this repository:

    git clone <https://github.com/Open-Cyber-Range/SDL-parser.git>
    cd wasm-sdl-parser
  2. Build the project and generate the WebAssembly binary:

    wasm-pack build --target web --release

    This will create a pkg directory containing the WebAssembly binary and a JavaScript wrapper for the parse_and_verify_sdl function.

  3. Integrate the generated files into your web application:

    <script type="module">
    import init, { parse_and_verify_sdl } from './pkg/wasm-sdl-parser.js';
    
    async function main() {
        await init(); // Initialize the WebAssembly module
    
        const sdl_text = `
            name: test-scenario
            description: some-description
            start: 2022-01-20T13:00:00Z
            end: 2022-01-20T23:00:00Z
        `;
    
        try {
            const scenario_json = parse_and_verify_sdl(sdl_text);
            console.log(scenario_json);
        } catch (error) {
            console.log(error)
        }
    }
    
    main();
    </script>

    Replace the sdl_text variable with the SDL text you want to verify.

Customization

If you need to customize the SDL validation logic, modify the parse_and_verify_sdl function in src/lib.rs.
