Composer Installation
The editor42/editor42 package is the editor's ready-to-use build, the same one you can download, for PHP projects that take their front-end libraries from Composer. There is no account and no key of any kind.
Install
composer require editor42/editor42
Basic Setup
The files land in vendor/editor42/editor42/. Serve that folder, or copy it into your public directory, and load the editor from it:
<script src="/editor42/editor42.min.js"></script>
<textarea id="my-editor"></textarea>
<script>
editor42.init({
selector: '#my-editor'
});
</script>
Keep the folder whole: editor42.min.js loads its plugins, skins, icons, themes and models from the folders next to it.
Updates
composer update editor42/editor42
The package carries the editor's own version number, so a constraint of ^42 takes every fix release.
