你可以正常定义接口:

interface MyInterface {
    Name:string;
}

但你不能这么做

class MyClass implements MyInterface {
    static Name:string; // typescript won't care about this field
    Name:string;         // and demand this one instead
}

为了表示一个类应该遵循这个接口来获取它的静态属性，你需要一点技巧:

var MyClass: MyInterface;
MyClass = class {
    static Name:string; // if the class doesn't have that field it won't compile
}

你甚至可以保留类名，TypeScript(2.0)不会介意:

var MyClass: MyInterface;
MyClass = class MyClass {
    static Name:string; // if the class doesn't have that field it won't compile
}

如果你想静态地继承许多接口，你必须首先将它们合并到一个新的接口中:

interface NameInterface {
    Name:string;
}
interface AddressInterface {
    Address:string;
}
interface NameAndAddressInterface extends NameInterface, AddressInterface { }
var MyClass: NameAndAddressInterface;
MyClass = class MyClass {
    static Name:string; // if the class doesn't have that static field code won't compile
    static Address:string; // if the class doesn't have that static field code won't compile
}

或者如果你不想命名合并接口，你可以这样做:

interface NameInterface {
    Name:string;
}
interface AddressInterface {
    Address:string;
}
var MyClass: NameInterface & AddressInterface;
MyClass = class MyClass {
    static Name:string; // if the class doesn't have that static field code won't compile
    static Address:string; // if the class doesn't have that static field code won't compile
}

工作示例

这里有一个相当简单的方法:

interface MyClass {
    new (): MyClassInstance;
    staticMethod(): string;
}

interface MyClassInstance {
    instanceMethod(): string;
}

const Class: MyClass = class {
    static staticMethod() {
        return "This is a static method";
    }
    instanceMethod() {
        return "This is an instance method";
    }
}

Class.staticMethod();

// Has type MyClassInstance
const instance = new Class();
instance.instanceMethod();

请注意，这并不允许您像通常那样让类扩展接口，但对于许多情况来说，这已经足够好了。

工作示例

简单的例子

interface Person {
  name: string;
  age: number;
}

abstract class Trackable {
  static TrackInstances: number;
}

class Pablo extends Trackable implements Person {
  constructor(public name: string, public age: number) { Pablo.TrackInstances+=1; }
}
console.log(Pablo.TrackInstances);

我执行了一个类似Kamil sot的解决方案，但却产生了意想不到的效果。我没有足够的声誉来发表这条评论，所以我把它贴在这里，以防有人正在尝试这个解决方案并阅读这篇文章。

解决方案是:

interface MyInterface {
    Name: string;
}

const MyClass = class {
    static Name: string;
};

但是，使用类表达式不允许我使用MyClass作为类型。如果我这样写:

const myInstance: MyClass;

myInstance的类型是any，我的编辑器显示以下错误:

'MyClass' refers to a value, but is being used as a type here. Did you mean 'typeof MyClass'?ts(2749)

我最终失去了一个比我想通过类的静态部分的接口实现的更重要的类型。

瓦尔使用装饰器的解决方案避免了这个陷阱。

其他解决方案似乎偏离了正确的路径，我发现我的场景在Typescript文档中有覆盖，我在下面解释:

interface AppPackageCheck<T> {
  new (packageExists: boolean): T
  checkIfPackageExists(): boolean;
}

class WebApp {
    public static checkIfPackageExists(): boolean {
        return false;
    }

    constructor(public packageExists: boolean) {}
}

class BackendApp {
    constructor(public packageExists: boolean) {}
}

function createApp<T>(type: AppPackageCheck<T>): T {
    const packageExists = type.checkIfPackageExists();
    return new type(packageExists)
}

let web = createApp(WebApp);

// compiler failure here, missing checkIfPackageExists
let backend = createApp(BackendApp);
