You can used to import the useService hook from the @web/core/utils/hooks package in Odoo's JavaScript framework.

// Example 

import { useService } from "@web/core/utils/hooks";

export const MyComponent = () => {

    setup() {

        super.setup();

        this.rpc = useService("rpc");

    }

    async onClickRPC() {

        await this.rpc("URL", {

            model: 'res.users',

            method: 'method_name',

            args: [],

            kwargs: {}

        })

    }

};
