custom typings files to angular 6

问题

I am trying to ad some custom typings definition file in angular but facing some error.

in app folder I have external folder in which I have external.d.ts file and below code

declare function format(input: string, ...args): string;

in tsconfig.json I tried adding "files": ["/app/external/external.d.ts"]

but its not working.

can somebody give me idea about adding custom typings file to angular 6.

回答1:

Add the custom typing file to typeRoots in tsconfig.json in the root folder work for me.

"typeRoots": ["node_modules/@types", "src/typings.d.ts"],

回答2:

The correct property is types inside tsconfig.json:
