Discontinuation of support for JS SDK

Support for the JS SDK Mapy.cz library will be discontinued. This library is technologically very outdated (it was created in 2006, the last version is from 2015), it does not meet modern standards and unfortunately, it is no longer possible to maintain it.

End of Support Schedule

  • September 2024 – A message warning about the end of support will begin appearing in the map and other JS components in a small format that will not significantly impact end users.
  • Fall/Winter 2024 – The message in the components will gradually increase in size.
  • Early 2025 – The message in the components will be larger, and end users will need to interact with it (e.g., close it).
  • End of 2025 – The components will stop functioning.

The schedule is tentative.


Currently, when using the Mapy.cz JS SDK, the following message appears in the browser’s developer console:

Switch to Mapy.cz REST API

We recommend preparing for this termination in advance and ideally switch to our new REST API Mapy.cz by mid-2024.

The REST API Mapy.cz was released in the summer of 2023 and serves as a successor to the JS SDK. We will continue to develop and support this solution. It is no longer about JavaScript components, but about a data REST API. Therefore, it can be used not only on the web but also in mobile, desktop, or server applications.

Read the recommended procedure for transitioning to the new REST API.

And if you have any doubts, do not hesitate to contact us, we will be happy to advise you on the transition to the new version.
