Plugin reference

API

Exposes an API for interacting with QWC2 via window.qwc2.

You can interact with the API as soon as the QWC2ApiReady event is dispatched.

For example:

window.addEventListener("QWC2ApiReady", () => {
     const {React} = window.qwc2.libs;

     class MyPlugin extends React.Component {
         render() {
             return React.createElement("div", {}, "Hello World");
         }
     }

     window.qwc2.addPlugin("MyPlugin", MyPlugin);
});

All following action functions are available:

I.e. setCurrentTask is available via window.qwc2.setCurrentTask.

Some of the core libraries (React, axios, ol, ...) are accessible via window.qwc2.libs.

In addition, the following methods are available on window.qwc2:
