[英]Import .d.ts types from external project
Say I have a project X with the following in its package.json: 假设我在package.json中有一个项目X,其中包含以下内容:
"typings": "lib/index.d.ts",
"types": "lib/index.d.ts",
I want to import all of the types from the index.d.ts file into another project. 我想将所有类型从index.d.ts文件导入另一个项目。
the index.d.ts file looks like: index.d.ts文件如下所示:
export declare const makePathExecutable: (runPath: string, cb: Function) => void;
export declare const checkForEquality: (arr1: string[], arr2: string[]) => boolean;
export declare const arrayHasDuplicates: (a: any[]) => boolean;
export declare const isStringWithPositiveLn: (s: string) => boolean;
export declare const findNearestRunAndTransform: (root: string, pth: string, cb: Function) => any;
export declare const findSumanMarkers: (types: string[], root: string, files: string[], cb: IMapCallback) => void;
export declare const isObject: (v: any) => boolean;
In my other project, I attempt to import these types like so: 在我的另一个项目中,我尝试像这样导入这些类型:
import * as X from "x"
but this doesn't really seem to work. 但这似乎并不奏效。
What is the right way to import these types? 导入这些类型的正确方法是什么?
Your project x
does not declare the types separately from the values. 您的项目
x
不会将值分别声明为类型。 So to access the type, you need to use typeof
: 因此,要访问类型,您需要使用
typeof
:
import * as X from 'x'
type MakePathExecutable = typeof X.makePathExecutable
// or
import { makePathExecutable } from 'x'
type MakePathExecutable = typeof makePathExecutable
