为 Visual Studio Code 创建一个“jsconfig.json”文件

Question

I am fairly new to Visual Studio Code and have been following a tutorial to create Node.js applications with Visual Studio Code.

I need to create a jsconfig.json file, the tutorial informs me that there should be a green lightbulb in the status bar, which will generate the file when clicked on. Unfortunately, I cannot see it and I am pretty sure that it should be showing, considering there is no jsconfig.json file in the 'myExpressApp' folder. Please see the screenshot...

Answer 1

Are you on a VSCode insiders build?

With recent versions of VSCode, if you are only using JavaScript, a jsconfig.json file is no longer required . If none is provided, the root directory will be treated as an implicit JavaScript project.

If you are working with TypeScript, you still need a tsconfig.json file. See @Aurora0001's answer for creating this.

I'll update the VSCode documentation/tutorial to reflect this change.

Answer 2

It seems odd that the lightbulb doesn't appear as expected, but you can still generate a jsconfig.json yourself. If you're planning to use TypeScript, you can just run this in your terminal (in the project directory):

$ tsc --init

This will create a tsconfig.json file ready for you (you'll need to then add "allowJs": true in that file, because that makes it equivalent to jsconfig.json ).

You could also just click 'New File', copy in the contents from the tutorial and save. There shouldn't be any detrimental effect to your project by not clicking the lightbulb to do it.

Answer 3

if you are a node-coder,it's good for you to learn typescript.here is the link http://www.typescriptlang.org/

and you can add the tsconfig.json file as the document on the link above. such like the code below

let a:number = 1;

ts will substitute js soon.
