Package Exports

hookar
hookar/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hookar) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

usage

import { createSequenceHooksCollection } from 'hookar'

const person = { title: 'mr', name: 'John Doe' }

/**
 *  Create a collection
 *  we don't need to supply the person object on creation
 *  but doing so gives us type completion
 */
const collection => createSequenceHooksCollection(person)

/**
 * add a hook
 */
const capitalizeTitle = person => { person.title = title.toUpperCase() }
const unregister = collection(capitalizeTitle)

/**
 * run the hooks on an object
 */
collection.run(person)

console.log(person) // { title: 'MR', name: 'John Doe' }

Hook Runners

Hookar comes with three hook runners:

createSequenceHooksCollection

This runner lets each hook mutate the provided object in the order the hooks are added. The return of the hook is ignored.

createParallelHooksCollection

This runner works like createSequenceHooksCollection, except hook are run in parallel.

createPipelineCollection

This runner provides each hook with the return value of the previously executed hook.
