Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `{
	"hello": "World"
}`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "json",
	automaticLayout: true,
});

Reproduction Steps

Using Starting with the basic Hello World.
Change language to json.
Then paste a large json string (approx 1Mb) into the preview pane.
NB: I cannot supply the json for privicy and security reasons.
Page locks up for just under 2 minutes.

Actual (Problematic) Behavior

Page freezes for just under 2 minutes

Expected Behavior

Page should not freeze

Additional Context

I think this might be the root issue for the following issues with running Monaco in Blazor
serdarciplak/BlazorMonaco#109
serdarciplak/BlazorMonaco#106

I thik the problem occurs when the JavaScript pane is executing myEditor.getModel() as hinted by the comment

VS Code Desktop app handles my large json file witout any issues.

Similar result is seen with 260k json file, however the delay befor the screen becomes responsive is shorter

My issue has now been solved by adding
builder.Services.AddSignalR(e => {
e.MaximumReceiveMessageSize = 1024 * 1024 * 100;
});

My issue is now fixed albeit with program.cs now like this

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();

builder.Services.AddSignalR(e => {
    e.MaximumReceiveMessageSize = 1024 * 1024 * 100;
});
