Features: - Create and manage doublets (links between source and target) - Create points (self-referencing links) - Delete links by ID - Search and filter links - Real-time operations log - Interactive web interface with modern UI Technical implementation: - WebAssembly bindings using wasm-bindgen - Simplified doublets store for demonstration - Responsive HTML/CSS interface - GitHub Actions workflow for automatic deployment - Self-contained demo that works without backend The web demo provides an accessible way for users to explore doublets concepts directly in their browser, making the library more approachable for new users and providing a testing ground for experimenting with doublets operations. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .github/workflows/deploy-demo.yml | 70 +++++ .gitignore | 1 + Cargo.lock | 114 ++++++-- Cargo.toml | 3 + README.md | 10 + web-demo/Cargo.toml | 25 ++ web-demo/README.md | 102 +++++++ web-demo/build.sh | 20 ++ web-demo/index.html | 465 ++++++++++++++++++++++++++++++ web-demo/package.json | 16 + web-demo/src/lib.rs | 230 +++++++++++++++ 11 files changed, 1027 insertions(+), 29 deletions(-) create mode 100644 .github/workflows/deploy-demo.yml create mode 100644 .gitignore create mode 100644 web-demo/Cargo.toml create mode 100644 web-demo/README.md create mode 100755 web-demo/build.sh create mode 100644 web-demo/index.html create mode 100644 web-demo/package.json create mode 100644 web-demo/src/lib.rs diff --git a/.github/workflows/deploy-demo.yml b/.github/workflows/deploy-demo.yml new file mode 100644 index 00000000..63d3ddda --- /dev/null +++ b/.github/workflows/deploy-demo.yml @@ -0,0 +1,70 @@ +name: Deploy Web Demo + +on: + push: + branches: [ main ] + paths: + -
