jchain - chain javascript functions

Installation

yarn add jchain

Or

npm install jchain

Usage

import chain from 'jchain'
// or
const chain = require('jchain');

// f = 6
const f = chain(
	(next, a, b) => {
		// a = 1, b = 2
		const e = next(3, 4) // e = 5
		return 6
	},
	(next, c, d) => {
		// c = 3, d = 4
		return 5
		// don't call next
	},
	(next) => {
		// next is noop
		// this is not invoked
	},
)(function noop(){}, 1, 2)

• async/await is support.
• error is thrown to the outer call.
• multiple chains can be combined. For e.g.,

chain(
	chain(
		next => {
			// do some thing
			next()
		},
		next => {
			// do some thing
			next()
		},
	),
	chain(
		next => {
			// do some thing
			next() // `next` param of the last chain is what passed to the outer call (`cb` in this case). Default is noop.
		},
	)
)(cb)
