How to create a npm package with multiple vue directives? Or should I create one package per directive?

Question

I am able to create an npm package by exporting a single vue directive in the src/index.js file. But how can I create a package that lets you use multiple vue directives. I am not able to export two vue directives in the same index.js file.

export default Vue.directive('directive1', {
  inserted: function (el, binding, vnode) {
    el.addEventListener('mouseup', (e) => mouseup(e, el, _data))
    el.addEventListener('mousedown', (e) => mousedown(e, el, _data))
    el.addEventListener('mousemove', (e) => mousemove(e, el, _data))
    setDraggerOffset(el, _data)
  }
})

export default Vue.directive('directive2', {
  inserted: function (el, binding, vnode) {
    el.addEventListener('mouseup', (e) => mouseup(e, el, _data))
    el.addEventListener('mousedown', (e) => mousedown(e, el, _data))
    el.addEventListener('mousemove', (e) => mousemove(e, el, _data))
    setDraggerOffset(el, _data)
  }
})

Answer 1

You are trying to export two defaults. A default means you can get the value by just saying import MyPack from 'path/to/package' . You need to export constants, and destructure where you are importing. Learn more here

In the package

export const vD1 = Vue.directive('directive1', {
  ...
})

export const vD2 = Vue.directive('directive2', {
  ...
})

Wherever you're importing:

import { vD1, vD2 } from 'path/to/package';

Check Vue Guide: Writing one plugin , we can follow this guide to develop our directives, then allow the users to activate specific directives by 2nd parameters= options .

Like below demo (assuming export myDirectives , and only enable directive1 ):

 let myDirectives = {} let _defaultDirectives = ['directive1', 'directive2'] myDirectives.directive1 = { inserted: function (el, binding, vnode) { el.addEventListener('mouseup', (e) => mouseup(e, el, _data)) el.addEventListener('mousedown', (e) => mousedown(e, el, _data)) el.addEventListener('mousemove', (e) => mousemove(e, el, _data)) console.log('directive1', `setDraggerOffset(el, _data)`) } } myDirectives.directive2 = { inserted: function (el, binding, vnode) { el.addEventListener('mouseup', (e) => mouseup(e, el, _data)) el.addEventListener('mousedown', (e) => mousedown(e, el, _data)) el.addEventListener('mousemove', (e) => mousemove(e, el, _data)) console.log('directive2', `setDraggerOffset(el, _data)`) } } myDirectives.install = function (Vue, options) { let selectedDirectives = (options && options.directives) || _defaultDirectives selectedDirectives.forEach((directive) => Vue.directive(directive, this[directive]) // this[directive + 'Definition'] = Vue.directive(directive, this[directive]) ) } // export default myDirectives // Vue.use(myDirectives) // default option is register both directive1 and directive 2 Vue.use(myDirectives, {directives: ['directive1'] }) // register directive1 only // console.log('Definition', myDirectives.directive1Definition, myDirectives.directive2Definition) new Vue({ el: '#app' })
