[DylanYang01]

always show loading,
value is not shown

[suren-atoyan]

what version do you use? could please share the console error if possible?

I've not taken a closer look into the issue, but it appears as this issue originates in '@monaco-editor/loader' at version 1.6.0, as my vite bundler throws the following error:

SyntaxError: The requested module '@monaco-editor/loader' does not provide an export named 'default'

When overriding the version of @monaco-editor/loader to 1.5.0, this error dissapears.

This also occurs for the current version 4.7.0 when being newly installed, probably caused be the used version selector.

same error here, downgrade loader to 1.5.0 fixed this problem, maybe related to https://github.com/microsoft/monaco-editor/releases/tag/v0.54.0

I've just set up a new project (with the latest Vite, TS + React) and used v4.8.0-rc.1. Don't see any issues 🤔cc @DearTanakorn @TobiasPressler @DylanYang01

Could you please share more info about your setup?

Same here (during vitest). Maybe related to suren-atoyan/monaco-loader#56 ?
this alias in vite.config seems to help handling it:

resolve: {
      alias: {
           '@monaco-editor/loader': '@monaco-editor/loader/lib/es/index.js',
      },
}

Same issue with latest release, vite, (TS + React), Error : exports is not defined in ES module scope.
This happens because the loader package isn’t marked properly as ESM-compatible.

The current tag no longer matches.

I am having an issue reproducing this. I've just tried it with Vite v5, 6 and 7

Could you please show how you use (+import) this package?
