Customize the Main Menu

There is a main menu bar at the top of the editor, and it is easy to add your own menu in this menu bar within the extension.

Registering menus

When an extension needs to add a menu, just fill in the object. For example, if we add a menu item to the "Extensions" menu, we can modify package.json with the following code example:

    // package.json
    "name": "hello-world",
    "contributions": {
        "messages": {
            "open-panel": {
                "methods": ["openPanel"]
        "menu": [
                "path": "i18n:menu.extension",
                "label": "Open Hello World",
                "icon": "./static/icon.png",
                "message": "open-panel"

The above configuration information will add a new "Open Hello World" menu in the "Extensions" menu of the editor. Clicking this menu will send an open-panel message to the current extension according to the message configuration, which will be triggered if the current extension is configured to listen to this message and the corresponding openPanel handler.

For the definition of messages, please refer to the documentation Customized Messages.

Let's look at the meaning of the fields in the menu object.
