Diagnostics for javascript

[Nuthin2do]

Hey there,

i have a question regarding the diagnostics:

In my application i set up some some language defaults like this:

const typescriptDefaults = languages.typescript.typescriptDefaults;
    typescriptDefaults.setDiagnosticsOptions({
      noSemanticValidation: false,
      noSyntaxValidation: false,
    });
    const tsOp = typescriptDefaults.getCompilerOptions();
    tsOp.allowJs = true;
    tsOp.checkJs = true;
    tsOp.target = languages.typescript.ScriptTarget.ES2020;
    tsOp.lib = ["ES6"];
    tsOp.isolatedModules = true;
    typescriptDefaults.setCompilerOptions(tsOp);

Earlier, when i used the plain monaco-api i got red underlines when i wrote something undefined, for example like this (the setting up of my own *.d.ts-files works flawlessly):

How can i achieve this with the monaco-vscode-api, too? Do i have to install a LSP for javascript (as described in the Wiki for python)? In the demo there is an error explicitly marked for this:

function inc () { variable++ }

in the main.common.ts, but if i write console.ggg() it is not marked as an error. Can anybody help me on that?

Thank you very much.

There is 2 way to provide javascript/typescript intellisense

When you were using the plain monaco-editor, you were using the monaco-worker

It can be used with monaco-vscode-api by installing and importing @codingame/monaco-vscode-standalone-typescript-language-features and registering the worker @codingame/monaco-vscode-standalone-typescript-language-features/worker as 'typescript' and 'javascript'

NewEditor.zip

I already did that... (see in the attached repo).

Thank very much for your help.

I'm not sure to understand the issue then

I want to have the red underlining when i type something undefined. For example if i write in the repo i provided something like console.ttt() i don't get notified that "ttt" does not exist on console like any IDE would do that. If i write console.ttt() in VSCode (the appllication, not the API) for example, the ttt() is red underlined and on hovering over it i get a message like this ->

And this red underlining with the notification i would like to have in the repo, too.

I found my mistake. Previously i set up the settings for typescript not for javascript. After changing that everything works fine:

private setTypescriptValidationOptions() { const javascriptDefaults = languages.typescript.javascriptDefaults; javascriptDefaults.setDiagnosticsOptions({ noSemanticValidation: false, noSyntaxValidation: false, }); const tsOp = javascriptDefaults.getCompilerOptions(); tsOp.allowJs = true; tsOp.checkJs = true; tsOp.target = languages.typescript.ScriptTarget.ES2020; tsOp.lib = ["ES6"]; tsOp.isolatedModules = true; javascriptDefaults.setCompilerOptions(tsOp); }
