esnextbin

Prototype JavaScript programs in the browser with ESNext (a.k.a ES2015) syntax and features, using modules from NPM.

ESNextbin

build status

Create browser programs with ES2015's latest features and use modules from NPM directly in your browser.

How it works?

  • The code gets transpiled by Babel.js v6 with stage-0, es2015 and react presets enabled
  • Browserify-CDN is responsible for importing npm modules and browserifying them on the fly
  • Github Gists are used for saving and sharing code sketches

Under the hood it's pure client-side application which is hosted on GitHub pages and is built upon React.js.

Usage

Explore latest JavaScript features with the help of several useful npm modules and when you're ready just save the result and share the link with your team mates or community.

Guide

  1. ESNextbin interface consists of 2 main sections - "Editor" on the left side and "HTML Preview" on the right side
  2. There are 3 editor tabs - "Code" (for Javascript), "HTML" (for html layout) and "Package" (package.json that gets updated automatically when you're executing the code which imports library from npm). Switch editors to manage specific part of your program
  3. Write program in "Code" tab and after you are ready hit ▶ Execute button to see the result
  4. If you have HTML layout or you're manipulating the DOM in your code you'll see the result in "HTML Preview".
  5. But all logging, errors and warnings that appear in runtime could be seen ONLY in your browser's console (maybe it's necessary to add "Console" tab?)
  6. Actions menu provides:
    • saving your code as public and private gists which can be easily shared by copy/pasting link that contains gist id as query param, e.g. http://esnextb.in?gist=<ID> (please notice that these actions require GitHub account authorization)
    • "Enable/Disable Autorun" toggles autorunning feature (when it's enabled, the code will be executed after 1s every time when you stop typing without pressing ▶ Execute button)
    • "Clean session" resets all editors and unauthorizes your GitHub account (if it was connected)
  7. "Editor" section uses default Ace shortcuts
  8. There are additional shorcuts as well:
    • Cmd/Ctrl + S - hotkeys for save your code as public gist action
    • Cmd/Ctrl + E - hotkeys for ▶ Execute button
