Make ajax requests without jQuery

Installation

$ npm i send-ajax

Example with Promise:

import * as sendAjax from 'send-ajax';

let postRequest = null;

const postData = (ajaxUrl, data = {}) => {
  return new Promise((resolve, reject) => {
    postRequest = sendAjax({
      url: ajaxUrl,
      method: 'POST',
      data,
      responseType: 'json',
      success: data => {
        resolve(data);
      },
      error: err => {
        reject({ error: true, message: 'Error message', data: err });
      },
    });
  });
};

const sendDataToServer = (url, data = {}) => {
  postData(url, data)
    .then(response => {
      console.log(response);
    })
    .catch(error => {
      console.error(error);
    })
    .finally(() => {
      // always executed
    });
};

Abort request:

if (postRequest) {
  postRequest.abort();
}

Example without Promise:

import * as sendAjax from 'send-ajax';

const postData = (ajaxUrl, data, success, error, after) => {
  return sendAjax({
    url: ajaxUrl,
    method: 'POST',
    data,
    responseType: 'json',
    success: data => {
      success(data);
    },
    error: err => {
      error(err);
    },
    after: () => {
      // always executed
    }
  });
};

const sendDataToServer = (url, data = {}) => {
  const postRequest = postData(
    url,
    data,
    response => {
      console.log(response);
    },
    error => {
      console.error(error);
    },
    () => {
      // always executed
    },
  );
  if (postRequest) {
    postRequest.abort();
  }
};
