TSLint - 删除装饰器上的空格

Question

I'm getting a TSLint error in VSCode, complaining that there is no white space after the "at" symbol in a decorator.

I have:

@Input()

but TSLint wants me to write:

@ Input()

What rule do I need to adjust in TS lint to remove this whitespace (ideally without affecting the whitespace around other elements)

Using tslint 5.11.0 and Typescript 2.3.3.

Here is my tslint.json:

When VSCode highlights the error, it also tells you the rule name which is causing that error.

Add following to your package.json under scripts.

"lint": "tslint \"app/**/*.ts\"",
"lintfix": "tslint --fix app/**/*.ts{,x}"

You can run following to find the issues in your code:

npm run lint

You can auto-fix the issues using following command:

npm run lintfix

Once you know the rule name, you can disable it in tslint.json file.
