VS Code 不对打字稿文件进行类型检查

Question

I'm trying to convert an existing codebase from flowtype to typescript, but VS Code will not report type errors in .ts files as expected.

Running tsc works as expected:

• I installed typescript and tslint as npm devDependencies .
• I added a <root>/tsconfig.json file.
• I added a test file in <root>/frontend/ts-example.ts with types that should fail very badly.
• Tried adding "typescript.validate.enable": true to my settings.json but it complained that was an unsupported setting.

What could I be missing here?

Answer 1

Welp, uh...

I had the "TypeScript and JavaScript Language Features" extension disabled in my workspace.

Yep, that'll do it...

In case anyone in the future is as stupid as I am, check: VS Code Extensions > Disabled.
