What is the process to gain entry to a Vue3 instance from another location in order to execute a specific function

Is there a way to access a Vue 3 instance when I am not aware of the variable name that holds this instance? I need to be able to execute a function from a specific component.

Upon typing $0.__vue_app__ in the console (Chrome Developer Tools), I can see the instance data. How can I use this information in my JS file?

console.log($0) would naturally return undefined.

What approach should I take in this situation?

Answer №1

To improve performance, consider implementing a web worker within the mounted() lifecycle hook like this:

methods: {
    myMethod(){
        console.log('Success!');
    }
},
mounted() {
    window["myThread"] = new Worker("./myThread.js");

    window["myThread"].onmessage = function(e) {
        if (e && e.data === 'execute_my_method') {
            this.myMethod();
        }
    }
}

In your myThread.js file, you can include:

this.postMessage('execute_my_method');
