Prerequisites

• Docker
• Cross

Installation

1. Clone the repository:

   git clone https://github.com/Lymphatus/libcaesium-wasm.git
   cd libcaesium-wasm

2. Install Cross:

   cargo install cross --git https://github.com/cross-rs/cross

3. Build the library:

   cross build --release

Usage

You can test the compression by copying the compiled libcaesium-wasm.js and libcaesium_wasm.wasm files into the static folder of the project. You can then open the static/index.html file to have a small demo of the usage.

The copy command should look like this

cp target/wasm32-unknown-emscripten/release/libcaesium-wasm.js static/libcaesium-wasm.js
cp target/wasm32-unknown-emscripten/release/libcaesium_wasm.wasm static/libcaesium_wasm.wasm

Note that the code by default is compiled as an ES6 Module, so it supports only modern browsers.
The library can be compiled as vanilla JS or UMD by tweaking the EMCC_CFLAGS inside Dockerfile.
