问题
I want to integrate flowjs or ng-flow to my Angular 2 application.
I've installed the flowjs typings using
npm install --save-dev @types/flowjs
from https://www.github.com/DefinitelyTyped/DefinitelyTyped/tree/types-2.0/flowjs
But when I import it in my component import { Flow } from 'flowjs'; the console thrown an error
/node_modules/@types/flowjs/index.d.ts' is not a module.
回答1:
I got this error before when creating my own modules and it was caused when there is nothing exported class or module inside the file index.d.ts. I looked at the repository and my guess is: the error is caused because there's nothing exported inside the file. But as same as other definition files you don't need to import the definitions, it is global definitions, so you just need to add it in your compiler life cycle using the "///ref" operator. I'm not used with this new Typescript definition files approach (@types), but there's a post explaining very well how to add it to your compiler life cycle: https://stackoverflow.com/a/39132461/5789456
回答2:
import * as Flow from "@flowjs/flow.js"
