Collect statistics on the use of open source

TOAST UI AppLoader applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI AppLoader is used throughout the world. It also serves as important index to determine the future course of projects. location.hostname (e.g. > β€œ") is to be collected and the sole purpose is nothing but to measure statistics on the usage. To disable GA, use the following usageStatistics options when creating the instance.

const options = {
  usageStatistics: false
const instance = new AppLoader(options);

Or, include tui-code-snippet.js (v2.2.0 or later) and then immediately write the options as follows:

tui.usageStatistics = false;

This component does not require the container element.


This component can be used by creating an instance with the constructor function. To get the constructor function, you should import the module using one of the following ways depending on your environment.

Using namespace in browser environment

const AppLoader = tui.AppLoader;

Using module format in node environment

const AppLoader = require('tui-app-loader'); /* CommonJS */
import AppLoader from 'tui-app-loader'; /* ES6 */

You should call exec method with options after creating an instance.

const appLoader = new AppLoader();
appLoader.exec({ ... });
