[英]Using TypeScript types from JS
I've enabled checkJS and allowJS in Typescript and created a simple fooInterface.d.ts file: 我在Typescript中启用了checkJS和allowJS并创建了一个简单的fooInterface.d.ts文件:
declare interface FooInterface {
x();
}
I'm trying to typecheck a JS file against this interface: 我正在尝试对此接口进行JS文件的类型检查:
/**
* @implements {FooInterface}
*/
class Bar {
y() {}
}
However I can't get it to throw an error upon running tsc
. 但是我无法在运行
tsc
时抛出错误。
Also tried simply writing declare class
, didn't work either. 也尝试过简单地编写
declare class
,也不起作用。
How can I reuse types from .d.ts files in JSDoc+JS? 如何重用JSDoc + JS中.d.ts文件中的类型?
Supporting the JSDoc @implements
tag has been requested in TypeScript and is tracked by https://github.com/Microsoft/TypeScript/issues/17498 在TypeScript中已经要求支持JSDoc
@implements
标记,并且可以通过https://github.com/Microsoft/TypeScript/issues/17498进行跟踪。
The @extends
tag will be supported in the next release of TypeScript (2.7) and is already available in the nightly builds (typescript@next) which, I might add, are remarkably stable. @extends
标记将在下一版本的TypeScript(2.7)中得到支持,并且在夜间构建(typescript @ next)中已经可用,我可以补充一下,该构建非常稳定。
You can get the nightly build with your package manager of choice. 您可以通过选择的包管理器进行每晚构建。 For example
例如
using npm 使用npm
$ npm install typescript@next
using jspm 使用jspm
$ jspm install typescript@next
using yarn 用纱
$ yarn add typescript@next
