Is there a way to let my code compile with ts-node even if there is unused property warnings in one line of my .ts file without setting "noUnusedLocals": false in my tsconfig.json file?

Since TypeScript 2.6 you can suppress errors with // @ts-ignore.
A
// @ts-ignorecomment suppresses all errors that originate on the following line. It is recommended practice to have the remainder of the comment following @ts-ignore explain which error is being suppressed.Please note that this comment only suppresses the error reporting, and we recommend you use this comments very sparingly.

If the error is an tslint error then you can disable them with
// tslint:disable-next-line
See https://palantir.github.io/tslint/usage/rule-flags/ for more information.

It is now possible to use _ for unused params.
function myFunc(_, b: string) {}
function otherFunc(_, _1, c: string) {} // multiple unsused
For me, this works to suppress an "unused variable" warning in a React project:
// eslint-disable-next-line @typescript-eslint/no-unused-vars
