Jan Provaznik	0fc9f9d3e7	Add version 4.2 to all existing migrations ... DB schema generated by a migration may look different in rails 4 and 5 (because rails 5 may use different default values). For this reason it's important to explicitly set for which rails version a migration was written for. See https://stackoverflow.com/questions/35929869/activerecordmigration-deprecation-warning-asks-for-rails-version-but-im-no/35930912#35930912	2018-11-22 13:18:28 +01:00
Phil Hughes	7b4b9e1cc4	Web IDE & CodeSandbox ... This enables JavaScripts projects to have live previews straight in the browser without requiring any local configuration. This uses the CodeSandbox package `sandpack` to compile it all inside of an iframe. This feature is off by default and can be toggled on in the admin settings. Only projects with a `package.json` and a `main` key are supported. Updates happen in real-time with hot-reloading. We just watch for changes to files and then send them to `sandpack` to allow it to reload the iframe. The iframe includes a very simple navigation bar, the text bar is `readonly` to stop users navigating away from the preview and the back and forward buttons just pop/splice the navigation stack which is tracked by a listener on `sandpack` There is a button inside the iframe which allows the user to open the projects inside of CodeSandbox. This button is only visible on **public** projects. On private or internal projects this button get hidden to protect private code being leaked into an external public URL.
