在 Visual Studio Code 中使用 TypeScript 时，如何将 TS 警告配置为显示为错误？

Question

For example, this example

async function a() { await null; }

has a small warning on await in VS Code

'await' has no effect on the type of this expression. ts(80007)

How do I make that warning behave like an error in VS Code and tsc (be more visible, fail compilation)?

Answer 1

In order for tsc to treat this as an error, there would need to be a compiler flag that you could set pertaining to async-await which I wasn't able to find looking through their docs .

There is, however, a linting rule (assuming you have eslint set up) which would cause your linter to complain in precisely this situation. See the eslint docs for an explanation of how it works.

All of that said, if you really want this behavior specifically. I think you could edit the category of this diagnostic message to be "Error" in your node_modules for typescript . That approach feels a bit brittle to me so I would definitely encourage the linter approach!

As far as integrating eslint with VSCode, there is a plugin which should integrate the linting warnings directly into the editor. I suspect you can add this to your VScode directly from their marketplace from within VSCode itself.
