Minimal Ember 3.28 app with runtime-defined components
Raw
readme.md

This is minimal Ember app example;

Created to show ability to modify Ember components without ember-cli and includes ember-template-compiler runtime.

To get same setup for you app, you should modify mentioned files and render <Main /> component in application.hbs template.

Build application, collect artifacts, and replace index.html with this example.

Step-by step example:

ember new reading-list

cd reading-list
  • edit environment.js specifying locationTyppe to none;
  • edit ember-cli-build.js to bundle ember-template-compiler;
  • create app/components/main.js file and put content from main.js into it.
  • edit app/templates/application.hbs and add <Main /> component into it.
