Is there any way to change 1 key to auto-type date?

[user283287427]

Hi, I'd like to auto-type today's date when I click the button under the Esc button, because I don't use this symbol.

Edit: I found this code and it works but pretty slow (in a delay). Do you think there's a better way to achieve that?

{
    "description": "hyper + d inserts datetime",
    "manipulators": [
        {
            "from": {
                "key_code": "non_us_backslash"
            },
            "to": [
                {
                    "shell_command": "osascript -e \"tell application \\\"System Events\\\" to keystroke \\\"$(date $@ +'%Y-%m-%d')\\\"\""
                }
            ],
            "type": "basic"
        }
    ]
}
