ymaps

npm version CircleCI

Yandex Maps on-demand promise-based widget loader.

  • Appends Yandex Maps API script to the document body.
  • Returns a promise which resolves as soon as the script has loaded and the API is ready.

This way the widget doesn’t load until it’s needed to decrease page load time.

Quickstart

Install from the command line:

npm install ymaps

Use in your code to load the widget:

import ymaps from 'ymaps';

ymaps
  .load()
  .then(maps => {
    const map = new maps.Map('your-map-container', {
      center: [-8.369326, 115.166023],
      zoom: 7
    });
  })
  .catch(error => console.log('Failed to load Yandex Maps', error));

To use another language simply pass a valid src to ymaps.load

ymaps.load('https://api-maps.yandex.ru/2.1/?lang=en_US').then(maps => {
  /* ... */
});

The information about other options is available in the API docs. Please check out known issues to see not supported options.

Running the tests

npm test

Known issues

  • load parameter, except when it's set to package.full is causing an error "TypeError: s is not a constructor". To reproduce, try to pass "//api-maps.yandex.ru/2.1/?lang=en_US&load=Map" to ymaps.load in the example above. PR is welcome!
