# Introduction

# What are the data resolvers?

The data resolvers are the way of manage the network/api calls and split them from the rest of application. All of available data resolvers you can find in the core/data-resolver directory. If you want to trigger a network call, you should create a new data resolver, and import it in the place where it's needed.

# How to create a data resolver

First of all, please create a type for it under the namespace DataResolver, then just create a new data resolver like this example below:

import { DataResolver } from './types/DataResolver';
import { TaskQueue } from '@vue-storefront/core/lib/sync'
import Task from '@vue-storefront/core/lib/sync/types/Task'

const headers = {
  'Accept': 'application/json, text/plain, */*',
  'Content-Type': 'application/json'

const myNewNetworkCall = async (data: string): Promise<Task> =>
    url: processLocalizedURLAddress(/* some endpoint */),
    payload: {
      method: 'POST',
      mode: 'cors',
      body: JSON.stringify({ data })

export const YourService: DataResolver.YourService = {
