You can use these two libs to download files http://danml.com/download.html https://github.com/eligrey/FileSaver.js/#filesaverjs

example

//  for FileSaver
import FileSaver from 'file-saver';
export function exportRecordToExcel(record) {
      return ({fetch}) => ({
        type: EXPORT_RECORD_TO_EXCEL,
        payload: {
          promise: fetch('/records/export', {
            credentials: 'same-origin',
            method: 'post',
            headers: {'Content-Type': 'application/json'},
            body: JSON.stringify(data)
          }).then(function(response) {
            return response.blob();
          }).then(function(blob) {
            FileSaver.saveAs(blob, 'nameFile.zip');
          })
        }
      });

//  for download 
let download = require('./download.min');
export function exportRecordToExcel(record) {
      return ({fetch}) => ({
        type: EXPORT_RECORD_TO_EXCEL,
        payload: {
          promise: fetch('/records/export', {
            credentials: 'same-origin',
            method: 'post',
            headers: {'Content-Type': 'application/json'},
            body: JSON.stringify(data)
          }).then(function(response) {
            return response.blob();
          }).then(function(blob) {
            download (blob);
          })
        }
      });
