exporting imports as a namespace with TypeScript

Question

My question is pretty much the same as this one: https://github.com/Microsoft/TypeScript/issues/4529

Say I have this:

//exported imports
export {ISumanOpts, IGlobalSumanObj} from 'suman-types/dts/global';
export {ITestCaseParam} from 'suman-types/dts/test-suite';
export {IHookParam} from 'suman-types/dts/test-suite';
export {IDescribeFn} from 'suman-types/dts/describe';
export {ItFn, ITestDataObj} from 'suman-types/dts/it';
export {IBeforeFn} from 'suman-types/dts/before';
export {IBeforeEachFn} from 'suman-types/dts/before-each';
export {IAfterFn} from 'suman-types/dts/after';
export {IAfterEachFn} from 'suman-types/dts/after-each';
export {DefineObjectContext as IDefObjCtx} from "./test-suite-helpers/define-options-classes";
export {DefineObjectTestCase as IDefObjTestCase} from "./test-suite-helpers/define-options-classes";
export {DefineObjectAllHook as IDefObjAllHook} from "./test-suite-helpers/define-options-classes";
export {DefineObjectEachHook as IDefObjEachHook} from "./test-suite-helpers/define-options-classes";


export namespace s {

  // ! I want to move all of the above exported items into a namespace here

}

Is there a way to use namespace or module to export things as a part of a namespace instead of individually exporting them?

I have this which is getting close:

So I tried changing them to imports and then putting them on a const like so:

But as you can see, some of my declarations are interfaces, not classes, and in that case looks like I get the error message "only refers to a type, but is being used as a value here".

Answer 1

Create a file name s.ts for example, where you want to export everything for your namespace :

export {ISumanOpts, IGlobalSumanObj} from 'suman-types/dts/global';
export {ITestCaseParam} from 'suman-types/dts/test-suite';
export {IHookParam} from 'suman-types/dts/test-suite';
export {IDescribeFn} from 'suman-types/dts/describe';
export {ItFn, ITestDataObj} from 'suman-types/dts/it';
export {IBeforeFn} from 'suman-types/dts/before';
export {IBeforeEachFn} from 'suman-types/dts/before-each';
export {IAfterFn} from 'suman-types/dts/after';
export {IAfterEachFn} from 'suman-types/dts/after-each';
export {DefineObjectContext as IDefObjCtx} from "./test-suite-helpers/define-options-classes";
export {DefineObjectTestCase as IDefObjTestCase} from "./test-suite-helpers/define-options-classes";
export {DefineObjectAllHook as IDefObjAllHook} from "./test-suite-helpers/define-options-classes";
export {DefineObjectEachHook as IDefObjEachHook} from "./test-suite-helpers/define-options-classes";

Then in your module you can just do :

import * as s from './s'

export {s}

It will export both types and values in a namespace called s. You can then import them using :

import {s} from 'your-module'

const anObject: s.ISumanOpts = {...}

What I do is this :

import * as Block from './block'
import * as FullNode from './full-node'
import * as ListOnChain from './list-on-chain'
import * as HashTools from './hash-tools'
import * as KeyValueStorage from './key-value-storage'
import * as SequenceStorage from './sequence-storage'
import * as SmartContract from './smart-contract'
import * as NodeBrowser from './node-browser'
import * as NetworkApi from './network-api'
import * as NetworkClientBrowserImpl from './network-client-browser-impl'
import * as NodeApi from './node-api'
import * as NodeImpl from './node-impl'
import * as NodeTransfer from './node-transfer'
import * as NodeNetworkClient from './node-network-client'
import * as WebsocketConnector from './websocket-connector'

export {
    Block,
    FullNode,
    ListOnChain,
    HashTools,
    KeyValueStorage,
    SequenceStorage,
    SmartContract,
    NodeBrowser,
    NetworkApi,
    NetworkClientBrowserImpl,
    NodeApi,
    NodeImpl,
    NodeTransfer,
    NodeNetworkClient,
    WebsocketConnector
}

Then in another file, I can import like this, and all will stay in their own space :

import * as AllComponents from 'blockchain-js-core'

If you want to import them one by one, you can do :

import {
    Block,
    FullNode,
    ListOnChain,
    HashTools,
    KeyValueStorage,
    SequenceStorage,
    SmartContract,
    NodeBrowser,
    NetworkApi,
    NetworkClientBrowserImpl,
    NodeApi,
    NodeImpl,
    NodeTransfer,
    NodeNetworkClient,
    WebsocketConnector
} from 'blockchain-js-core'
