Monaco Editor Playground Code

No response

Actual Behavior

It takes up to 5 seconds to load which slows the site

Expected Behavior

Is it possible to get it to 2 seconds or less

Additional Context

Hi, I am using Monaco editor for a project however it takes quite a while to load. In my code, I even define the language which when I looked should improve the loading time however it still hasn't improved. Is there anything else that is possible to do so that the performance improves? Maybe some settings in JSON or in the editor itself. I couldn't find any relevant reference to it.

Can you try to figure out if there is anything that does not need to be loaded in your case?

We always try to have a fast loading editor, but your feature request is quite unspecific.

We have issues with loading the editor initially. It takes 5 seconds to show up on the first time. We found out that editor.main.js which is about 3.5MB takes 4 seconds to load. as soon as this loads editor becomes available

Then maybe just my configuration is wrong. How can I test if everything I am using is required and if not then disable it to use just the bare minimum for it to make it work and perform better?

You can use the dev tools of your browser to see which scripts get requested.
Or check webpack which sources are bundled.

Monaco-editor/esm/vs gets loaded in the webpack other than that it's a bunch of different scripts
