Or Monaco, as well as to interoperate with other client-side The same approach can be used to integrate other rich editors such as Ace Register a form-submission event handler to pull out content from the CodeMirror editorĪnd inject that back into the textarea ready for sending to the server.Pull out any existing content from a textarea and inject that into a CodeMirror editor.Summaryīy annotating a form element with phx-hook we can ask LiveView to execute ourĬustom JavaScript within the lifecycle of that component. You can accomplish this with a bit of CSS, e.g. Sorry, your browser doesn’t support embedded videos.Īll that’s left to do is hide the textarea. We can now enter text in the editor, submit the form, and see the textareaĬontents are synchronised! It looks like this: ![]() Snippet default_language " python " log_interval 1_000 def mount ( _params, _session, socket ) do socket = socket |> assign_initial_changeset () |> assign ( : running, false ) |> assign ( : logs, ) ) SnippetExecutionLive do use CodeRunnerWeb, : live_view import Ecto. ![]() Lib/code_runner_web/live/snippet_execution_live.ex.

Next, generate the files which will back our data model: a single snippets $ mix phx.new code_runner -database sqlite3 Wiring up the LiveView state are out of the way, we’ll to extend theįorm to use CodeMirror’s fancy editor for a nicer userĬreate a new Phoenix project 1 to begin, backed by SQLite to avoid having How can we inject the most recent code into the editor on revisiting theĮventually I settled on using LiveView’s client-side phx-hookīefore adding CodeMirror, we’ll create a new Phoenix application which has theįunctionality we’re after using vanilla HTML elements.Include the editor contents in the form data?

I’ve been playing around with an application where users can submit code Either way, the full application is available on Setup and to jump straight to the CodeMirror integration If you already have a Phoenix application up and running you might like skip the ![]() We’ll go over how to do just that for the web-basedĬodeMirror editor, demonstrating how to integrate an editor into a Interactions, but it’s not always obvious how to leverage this for a specific Phoenix has lots of JavaScript interoperability for client-side The LiveView component of the Elixir web framework ![]()
