TypeScript / JavaScript - 导入所有类型 [英] TypeScript / JavaScript - import all types

问题描述

如何从某个文件导入所有类型？

How can I import all types from certain file?

假设我有 myClass.ts 和 otherClass.ts 。
我想从 otherClass.ts 导入所有类。

Let's say I have myClass.ts and otherClass.ts. I want to import all classes from otherClass.ts.

我看过很少的语法导入。

I've seen few syntaxes for imports.

import ClassA, { ClassB, ClassC } from 'otherClass';

import * as foo from 'otherClass';

import foo = require('otherClass');

import 'rxjs/Rx';

1. 首先需要我列出所有内容。我想导入所有类型。

1. The first needs me to list everything. I'd like to import all types.

第二种语法需要名称空间前缀： foo.ClassA 。

The second syntax needs the namespace prefix: foo.ClassA.

我知道最后一个是TypeScript 1.4，但仍然受支持。

I understand that the last one is TypeScript 1.4, but still supported.

是否有如下内容？

import * from "otherClass";
...
   var x = new ClassA()

此外，什么是 {...} 的含义以及一些类型在外面和一些内部？

Also, what's the meaning of the { ... } and some of the types being outside and some inside?

文档没有提示任何此类内容。

The documentation doesn't hint anything such.

推荐答案

使用ES6模块，最接近你的东西你想要的是命名空间导入：

With ES6 modules, the closest thing you have to what you want is a namespace import:

import * as foo from './otherClass';

您可以在 import 文档。

You can see the available kinds of imports in the import documentation.

此外，{...}的含义是什么，有些类型在外面，有些在里面？

Also, what's the meaning of the { ... } and some of the types being outside and some inside?

您可以在我引用的文档中或我的回答。

You can read about that in the documentation I referenced or in my answer here.
