ember-render-to-string

A component to render any Ember template to string. Works with Ember 2.10+(Glimmer 2) and FastBoot!

Motivation

There is a need sometimes to render Ember Template to string without poluting the rest of the page with unwanted content. It is especially useful for making wrappers for third-party libraries where you can pass innerHTML of element. For example ember-medium-editor uses it to pass innerHTML for buttons.

Implementation is borrowed from awesome ember-composability-tools but ember-wormhole addon was replaced by native in-element helper which still private API but there is RFC to promote it to public.

Installation

• With ember: ember install ember-render-to-string
• With yarn: yarn add --dev ember-render-to-string
• With npm: npm install --save-dev ember-render-to-string

Usage

import Component from '@ember/component';

export default Component.extend({
  items: ['Ember', 'Vue', 'React'],

  actions: {
    returnInnerHTML(html) {
      console.log(html); // '<h2>Can you see me?</h2>'
    },

    returnJustText(text) {
      console.log(text); // 'Can you see me?'
    },

    returnDOMNode(node) {
      console.log(node.tagName); // 'DIV'
    },

    returnCustomDOMNode(node) {
      console.log(node.tagName); // 'BUTTON'
    },

    anyEmberHelper(html) {
      console.log(html); // '<ul><li>Ember</li><li>Vue</li><li>React</li></ul>'
    }
  }
});
