Angular4 + Angular CLI 支持 Javascript AngularJS？

Question

Is it possible to get angular4 + angular CLI to support Javascript files?

I have a legacy angularJS application written in javascript that I want to import components from in my Angular4 application using the upgrade module. The current problem I am facing is that the angularCLI doesn't seem to be loading/building the included javascript components/files in the project that I added.

I am currently following this guide which doesn't mention getting javascript angularjs components into angular4: https://angular.io/guide/upgrade

Thanks!

Answer 1

Anything you can do with Angular in TypeScript, you can also do in JavaScript. Translating from one language to the other is mostly a matter of changing the way you organize your code and access Angular APIs.

you may find documentation here .

Answer 2

you can use declare keyword in typescript . Try link your old angularjs file into html with script tag. Then declare that component which you want to use from old angularjs in Angular 4/typescript like:

declare var YourComponent;
