[英]How to import type in typescript?
I have following export: 我有以下出口:
import * as jwt from 'jsonwebtoken';
...
export type JsonWebToken = typeof jwt;
Then, i try to use it like so: 然后,我尝试像这样使用它:
export class AuthService {
constructor(
@Inject(constants.JWT) private readonly jsonWebToken: JsonWebToken,
// error here ^
){}
I'm getting this error, that pointing to JsonWebToken
: 我收到此错误,指向
JsonWebToken
:
ReferenceError: jwt_provider_1 is not defined

Nest's dependency injection is not designed to work with non-DI types (such as the JWT library). Nest的依赖项注入不适用于非DI类型(例如JWT库)。 My recommendation would be to make a wrapper component, using the jwt library according to ITS docs, then inject your wrapper to your controllers normally.
我的建议是根据ITS文档使用jwt库制作包装器组件,然后将包装器正常注入控制器。
@Component()
export class JWTComponent {
signJwt(data) {
jwt.sign() // etc.
}
verifyJwt() {
jwt.verify() // etc.
}
}
After some diggin in i got next solution: 经过一番挖掘之后,我得到了下一个解决方案:
import * as types from '...';
// then you can use it like so:
jsonWebToken: types.JsonWebToken,
But this solution is dumb and makes me sad. 但是这种解决方法是愚蠢的,让我感到难过。 Is this a typescript bug or what?
这是打字稿错误还是什么?
