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().


function increment(props, state) {
return {
value: state.value + props.step,
function decrement(props, state) {
return {
value: state.value - props.step,
window.Promise || document.write('<script src=""><\/script>');
window.fetch || document.write('<script src=""><\/script>');

Webpack in-memory filesystem
var webpack = require('webpack');
var MemoryFS = require('memory-fs');
var SingleEntryDependency = require('webpack/lib/dependencies/SingleEntryDependency');
var fs = new MemoryFS();
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)
  • view is pure!
