Transform (Rust WASM Playground)

A lightweight Rust/WebAssembly rewrite of the original transform-go toolbox. It provides a browser UI (www/) backed entirely by the wasm_core crate compiled to WebAssembly. Current features include:

• UUID & ULID generation (v1-v8, GUID uppercase)
• User-Agent catalog with quick filtering
• Base encoders/decoders + hash digests
• URL & JWT encode/decode helpers
• Number-base converter, IPv4 calculator
• JSON ⇄ YAML/TOML/XML/JSON Schema/Go Struct conversions
• Markdown ⇄ HTML pair tool driven by the wasm module

Project layout

transform/
├── Makefile             # convenience tasks (fmt, lint, build)
├── wasm_core/           # Rust crate compiled to WebAssembly
└── www/                 # static frontend (vanilla JS + CSS)

Prerequisites

• Rust toolchain (1.78+ recommended) with wasm32-unknown-unknown target
• wasm-pack in PATH for make build
• Node/npm (only if you plan to serve www/ via your own dev server)

Install requirements:

rustup target add wasm32-unknown-unknown
cargo install wasm-pack # if not already installed

Common tasks

make fmt          # cargo fmt on wasm_core
make lint         # cargo clippy -D warnings (passes after this change)
make build        # wasm-pack build --target web --out-dir www/pkg
make serve        # simple static dev server for www/ (see Makefile)

You can also run tests directly:

cd wasm_core
cargo test

Running locally

1. Build the wasm bundle:

   make build

2. Serve the www/ directory (use make serve or your own static server).
3. Visit http://localhost:3000 (default from the Makefile server) to use the tools.

Continuous integration

GitHub Actions (.github/workflows/ci.yml) ensures formatting, linting, and tests stay green on every push/PR.
