Documentation

Codesandbox.io for Atom

apm install atom-codesandbox

An Atom package that let's you magically preview your current file in a Codesandbox pane.

No dependency management needed, just import or require what you need and Codesandbox's hosted bundler Sandpack will hot-reload and preview your code!

How-to

Create a javascript file, save it, then run Codesandbox: Toggle Preview Pane from the Command Palette.

For example:

import randomColor from 'randomcolor'

console.log(randomColor())

You'll see a random color appear in the Preview Pane console!

Psst: You can also create a new scratch file in your temp directory by running Codesandbox: New Scratch Pad

Rendering

There's a <div id="root"></div> that's available to your code, if you want to render something to the DOM.

For example with React:

import React from 'react'
import { render } from 'react-dom'

render(<marquee>Hello world!</marquee>, document.getElementById('root'))

Package Versions

You can import a specific package version by appending the version to the package name, prefixed by an '@' character:

import React from 'react@16.5.2'
// named tags also work
// import React from 'react@next'

Keymap

This package does not assign a shortcut by default, you can run Application: Open Your Keymap from the Command Palette add one of your choosing to your keymap.cson:

'atom-text-editor:not([mini])':
  'ctrl-alt-c': 'codesandbox:toggle-preview-pane'
  'ctrl-alt-n': 'codesandbox:new-scratch-pad'

Caveats

There's no support (yet) for special configuration via package.json or webpack.config.js.

Working on Top Secret Stuff?

This package will only look at the active file and recursively gather its dependencies and file contents. The gathered files are only bundled locally in a ServiceWorker and never sent to Codesandbox or a third party. Nothing will be persisted until you choose to 'Open In Codesandbox' at which point they are turned into a dedicated Sandbox.
