RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including rstore. Try it out:
const store = require('rstore').store;
// prints out '0' once (the initial state, that does not change)
store(0)
.subscribe(v => console.log(v));
const one = {
subscribe: next => next(1)
};
// prints out '0' and then '1' (0 - initial state, 1 - a value from the 'one' stream)
store(0)
.plug(one, (s, u) => u)
.subscribe(v => console.log(v));
const random$ = {
subscribe: (next) => {
const t = setInterval(()=> next(Math.random()), 300);
return () => clearInterval(t);
}
};
// prints out 0 and then random values endlessly
store(0)
.plug(random$, (s, u) => u)
.subscribe(v => console.log(v));
