Introduction

The fast, 3KB JavaScript framework for "echoing" reactive UI in functional style.

What is EchoX

A quick example of EchoX:

EchoX.component(
  EchoX.reactive()
    .let("value", 0)
    .let("increment", (d) => () => d.value++)
    .let("decrement", (d) => () => d.value--),
  html.div()(
    html.button({onclick: (d) => d.increment})("👍"),
    html.button({onclick: (d) => d.decrement})("👎"),
    html.span()((d) => d.value),
  ),
)

Why EchoX

• Fast - No Compiling, but Fine-tune Reactivity and No Virtual DOM Diff
• Small - Zero Dependencies, 3KB (gzip)
• Simple - 16 APIs, 1 Hour Learning
• Productive - Structural Code, but Nicely Reusable Logic and Flexible Organization of Concerns
• Pragmatic - No Transpiling, but Readable Template and Fully TS Support
