vue-emit v1.1.0

Vue emit

Helper function to emit events from Vue.js functional components. Can be used in regular components too. CodeSandbox demo

Installation

yarn add vue-emit
# or
npm install vue-emit

Usage

import emit from 'vue-emit';

export default {
  functional: true,
  render (h, context) {
    return (
      <button
        onClick={e => emit(context.listeners, 'someEvent', e, 'additional param', 'etc')}
      >
        {context.children}
      </button>
    );
  },
};

Params

emit(handlers_list, event_name, [optional_payload]);

• handlers_list - object of functions. In Vue this is this.$listeners and context.listeners (for funtional components). Each value may be a function or an array of functions. In case of array emit will call all provided callbacks.

• event_name - name of the event to fire. The event may not be defined in the handlers list: in this case emit does nothing and do not throws an error (what is very handy)

• optional_payload - any amount of parameters that will be passed as arguments to the callback.
