以尽可能少的重复从另一个文件导入声明?

客户端类型

declare module 'client-types' {
    export interface IRequestBody { type: 'request' }
    export interface CreateProjectRequestBody extends IRequestBody { cmd: 'otii_create_project' }
    export interface GetArcsRequestBody extends IRequestBody { cmd: 'otii_get_devices' }
    export interface OpenProjectRequestBody extends IRequestBody { cmd: 'otii_open_project', payload: { value: string, force: boolean, progress: boolean } }

    export interface IResponse {}
    export interface CreateProjectResponse extends IResponse { payload: { project_id: number } }
    export interface GetArcsResponse extends IResponse { payload: { devices: [ { device_id: number, name: string, type: string } ] } }
    export interface OpenProjectResponse extends IResponse { payload: { project_id: string } }

    export interface ResponseDevice { device_id: number, name: string, type: string }

    export interface CreateProjectResponseData { id: number }
    export interface GetArcsResponseData { [index: number]: {id: number, name: string} }
    export interface OpenProjectResponseData { id: number }
}

索引

// imports
import { 
    IRequestBody, 
    CreateProjectRequestBody, 
    GetArcsRequestBody, 
    OpenProjectRequestBody,
    IResponse,
    CreateProjectResponse,
    GetArcsResponse,
    OpenProjectResponse,
    ResponseDevice,
    CreateProjectResponseData,
    GetArcsResponseData,
    OpenProjectResponseData
} from 'client-types';

// use
request(body: CreateProjectRequestBody) : Promise<CreateProjectResponse>
request(body: GetArcsRequestBody) : Promise<GetArcsResponse>
request(body: OpenProjectRequestBody) : Promise<OpenProjectResponse>
request<T extends IRequestBody>(body: T): Promise<IResponse> {
    ...
}

async createProject() : Promise<CreateProjectResponseData> { 
    ...
}

import * from from 'client-types';

[ts] 'as' expected.

有没有办法消除这种重复(就像我感觉的那样),或者我已经在使用“最佳实践”?

PS:我正在编写的代码将成为一个npm包。让我知道,如果你认为有什么npm的具体我应该知道有关这个问题。
