在Angular和nodeJS中使用公共Javascript文件

NodeJS 作为

var sum = require('./sum.js');

但我没能用上它 Angular var require: any;

 declare var require: any;
 var sum = require('./sum.js');

我发现 this

您可以创建一个npm包并在以下两种情况下使用它:

"scripts": [
    ....
    "./assets/js/sum.js"
],

import * as sum from '../../........./sum.js' //ref of ur file

class xyz {
   let a = 0,b=1
   constructor() { sum.addNumber(a, b); }
}
