Middleware helpers for use with hyperapp.
npm install hypermiddleware
The middleware
function takes an array of Hyperapp middleware functions, and returns a single middleware function. Hyperapp's middleware property takes a single function, but sometimes, you want to compose multiple middleware functions. The middleware
function makes this simple:
Example:
app({
// ... other stuff ...
middleware: middleware([middleware1, middleware2, middleware3]),
});
The loggerMiddleware
function logs all actions and the resulting state out to the console, similar to redux-logger for Redux.
Example:
app({
// ... other stuff ...
middleware: loggerMiddleware,
});
The following is the Hyperapp add / subtract demo, but with two middleware functions composed into it.
import { middleware, loggerMiddleware } from 'hypermiddleware';
import { h, app } from 'hyperapp';
// Just as an example...
function helloMiddleware(next) {
return (action, props) => {
console.log('HEYO!!!!!!!!!!!!!!!!!!');
return next(action, props);
};
}
const Add = x => x + 1;
const Sub = x => x - 1;
app({
init: 0,
view: state =>
h('div', {}, [
h('h1', {}, state),
h('button', { onClick: Sub }, '-'),
h('button', { onClick: Add }, '+')
]),
middleware: middleware([loggerMiddleware, helloMiddleware]),
node: document.getElementById('app')
});
