Examples

  Compile a CLI tool:

    git clone --depth 1 https://github.com/jashkenas/coffeescript.git
    cd coffeescript
    nodec bin/coffee
    ./a.out (or a.exe on Windows)

  Compile a web application:

    git clone --depth 1 https://github.com/eggjs/examples.git
    cd examples/helloworld
    npm install
    nodec node_modules/egg-bin/bin/egg-bin.js
    ./a.out dev (or a.exe dev on Windows)
