nemo-web

Interactive Web-Frontend for the Nemo Rule Engine/Reasoner.

This project uses:

• Web assembly to execute the Nemo Rule Engine which is written in Rust
• Web workers to perform heavy computation in the background (Nemo reasoning, Monaco editor)
• File system API for downloading reasoning results

Development

After building the Nemo WASM library, start a development server:

# Copy nemo VSIX extension to the correct location
mkdir nemoVSIX
cp $PATH_TO_NEMO_VSIX nemoVSIX/nemo.vsix
# Copy nemo-wasm library to the correct location
cp -r $PATH_TO_NEMO_WASM/nemoWASMBundler ./nemoWASMBundler

npm install
npm run dev

Before committing changes:

npm run lint

Technologies used in this project

• Programming language: TypeScript
• Single page application framework: Vite
• Rendering: React.js
• State management: React.js and Redux
• Code editor: Monaco Editor

Getting started

Useful starting points for hacking on the code:

• Implementation of the program execution panel: src/components/rightPanel/executionPanel/ExecutionPanel.tsx
• Interaction with the Nemo web assembly API: src/nemoWorker/NemoRunner.ts
• Example Nemo programs: src/components/examples/files/listOfExamples.ts
• Nemo Syntax highlighting and other language features: src/components/leftPanel/editor/monacoLangaugeNemo.ts

Production build

After building the Nemo WASM library, create a production build in the dist folder that can be served by a static web server:

# Copy nemo-wasm library to the correct location
cp -r $PATH_TO_NEMO_WASM ./nemoWASM

npm install
npm run build
npm preview
