# create-merged-request · [![npm version](https://badge.fury.io/js/create-merged-request.svg)](https://badge.fury.io/js/create-merged-request)

Merge scattered requests into one, distribute corresponding result to requestor.

## Install

```bash

npm i create-merged-request rxjs # Please note that rxjs is peer dependency of it

```

## Usage

For example if you have tons of user query in different components and you want

to combine theme into one.

```ts

import { createMergedRequest } from 'create-merged-request'

// `string` is user id

// `User[]` is the response data type that `createRequest` resolves

// `User` is the data type that `createResponse` returns

const mergedRequest = createMergedRequest({

  thresholdMs: 0, // time threshold to merged request into one request

  createRequest(ids) {

    return fetchUsers(ids) // `fetchUsers` type: (ids: string[]) => Promise

  },

  createResponse(id, users) {

    return users.find((user) => user.id === id)! // return type: User

  }

})

// `fetchUsers` will be called only once

mergedRequest(userId1).then((user) => console.log(user))

mergedRequest(userId2).then((user) => console.log(user))

mergedRequest(userId3).then((user) => console.log(user))

```
