Compiling your plugin

Our custom Windy Plugin Compiler does all the job for you. Just run npm start to launch it or npm run start-dev to skip beginner's prompt.

Publishing your plugin

1) Make sure, that your package.json is updated, and that:

+ name, is unique name of your plugin
+ description, describes what your plugin does
+ author and repository reflects your name and where the plugin hosted is

2) Remove this and put there few words about your plugin (and maybe some screenshot if you want). The text from README file will be used in our planned plugins gallery. 3) Publish your plugin as npm package by npm publish. (If you are not familiar with npm, create and account and login:
4) Test your published npm package on Windy's Plugin page 5) Let us know in our community about your new achievement. 6) Once you are satisfied with your plugin, you can request permission for it to be approved. Your plugin will then be listed in the "" gallery, and you will be able to use the url query string. 7) Commit your work and pull your repository back to GitHub. Rename your repository to reflect name of your plugin.


It is strictly prohibited to use plugin to:

  • Modify user's setting without his consent
  • Download any of user's settings, favorites or location to your server
  • Download any meteorological data from Windy to your own server or use them in any other scope than inside your plugin
  • Do any action that would harm our privacy policy

Enterprise use

We prepare Windy Enterprise project, that will enable to 1) Use private plugins (not published publicly) 2) Limit access to your data just to your invited users 3) Let us know if you want to be informed about this project

Things to remember

  • While providing coordinates to Leaflet can be done via object { lat, lng } with lng property, Windy supports { lat, lon } with lon property.
  • Using undocumented functions of Windy API can break your plugin, when we decide to upgrade our codes. If you miss something, rather let us know here and ask us to document and expose other features.
