是ES2015,我该如何动态导入模块？
例如.代替…
import {SomeClass} from 'lib/whatever/some-class';
我不知道运行时的路径,所以我希望将路径存储在变量中,并且我想从该模块导入特定的东西：
function doDynamicStuff(path) {
let importedThing = ...; //import * as importedThing from path;
let thingIReallyWant = importedThing.someExportedVariable;
...
}
我不确定使用什么语法,或者根本不可能这样做.我尝试使用let importedThing = require(path);但是我们没有使用RequireJS.
In current JavaScript module systems,you have to execute the code in order to find out what the imports and exports are. That is the main reason why ECMAScript 6 breaks with those systems: by building the module system into the language,you can syntactically enforce a static module structure.
…
A module’s structure being static means that you can determine imports and exports at compile time (statically) – you only have to look at the source code,you don’t have to execute it.
从ECMAScript 6 modules: the final syntax起
要动态导入模块,您必须明确使用模块加载器(如RequireJS或SystemJS)
