tracked npm

@tracked is a decorator for Preact that makes working with state values no different than properties on your component instance.

It's one 300 byte function that creates a getter/setter alias into state/setState() for a given key, with an optional initial value. The "magic" here is simply that it works as a property decorator rather than a function, so it appears to integrate directly into the language.

tracked has no dependencies and works with any component implementation that uses this.state and this.setState().

Installation

function increment(props, state) {
return {
value: state.value + props.step,
};
}
function decrement(props, state) {
return {
value: state.value - props.step,
};

var fs = new MemoryFS();
fs.mkdirpSync('/src');
fs.writeFileSync('/src/app.js', 'require("./dep.js")', 'utf-8');
fs.writeFileSync('/src/dep.js', 'module.exports = function(msg){console.log(msg)}', 'utf-8');
fs.writeFileSync('/src/extra-entry.js', 'require("./dep.js")', 'utf-8');

architectures and whatnot

  1. plain ol' React
let state = initial
render(view(state), element)
