How to hide bootstrap offcanvas in vue3 when router-link is clicked?

Good day, I would like to hide bootstrap-5/Offcanvas when I click on link inside. Here is Offcanvas:

  //Button activate Offcanvas
  <button class="navbar-toggler" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasDarkNavbar"
          aria-controls="offcanvasDarkNavbar">
    <span class="navbar-toggler-icon"></span>
  </button>
  //Offcanvas
  <div class="offcanvas offcanvas-end text-bg-dark" tabindex="-1" id="offcanvasDarkNavbar"
       aria-labelledby="offcanvasDarkNavbarLabel">
    <div class="offcanvas-header">
      <h5 class="offcanvas-title" id="offcanvasDarkNavbarLabel">Menu</h5>
    </div>
    <div class="offcanvas-body">
      <ul class="nav nav-pills flex-column mb-sm-auto mb-0 align-items-center align-items-sm-start" id="menu">
        <li class="nav-item">
          <router-link to="/about" class="nav-link link-info align-middle px-0">
            <i class="fs-4 bi-house"></i> <span class="ms-1 d-none d-sm-inline">Home</span>
          </router-link>
        </li>
      </ul>
    </div>
  </div>

In official docs they say:

You can create an offcanvas instance with the constructor, for example: var myOffcanvas = document.getElementById('myOffcanvas') OR var bsOffcanvas = new bootstrap.Offcanvas(myOffcanvas)

and then use method "hide". I tried to use in router-link @click="hideThisCanvas" and then

methods: {
  hideThisCanvas(){
    let myOffcanvas = document.getElementById('offcanvasDarkNavbar')
    myOffcanvas.hide();
  }
}

but it gives the error myOffcanvas.hide is not a function. Please, help!

"Clicking" toggler works as well. Create function that your router-links calls via @click:

function closeOffcanvas() {
   document.getElementById('offcanvasToggler').click()
}

Toggler must have id:

<button id="offcanvasToggler" class="navbar-toggler" data-bs-toggle="offcanvas" data-bs-target="#offcanvas" aria-controls="offcanvas">

And router just calls function to evoke click:

<router-link :to="{ name: 'home'}" class="nav-link" @click.prevent="closeOffcanvas()">

I'm sure a nicer vue-like code using ref as mentioned above exists. This one works for me as is. You can also reference close button if you have it, the one with

data-bs-dismiss="offcanvas"

you have to create an offcanvas instance with the constructor, for example:

methods: {
  hideThisCanvas(){
    let myOffcanvas = document.getElementById('offcanvasDarkNavbar')
    let bsOffcanvas = bootstrap.Offcanvas.getInstance(myOffcanvas);
    bsOffcanvas.hide();
  }
}

OR

methods: {
      hideThisCanvas(){
        let myOffcanvas = document.getElementById('offcanvasDarkNavbar')
        let bsOffcanvas = new bootstrap.Offcanvas(myOffcanvas);
        bsOffcanvas.hide();
      }
    }

Because using traditional document selectors is not ideal for modern JS framework, you can create a ref for your offCanvas like this.

<div ref="offCanvas" class="offcanvas offcanvas-start" tabindex="-1" id="example_canvas">

Then access it in your vuejs function the way you should

example

let myOffcanvas = this.$refs.offCanvas;

your final method should be something like this

methods: {
      hideThisCanvas(){
        let myOffcanvas = this.$refs.offCanvas;
        let bsOffcanvas = new bootstrap.Offcanvas(myOffcanvas);
        bsOffcanvas.hide();
      }
    }

I do not know so much about vuejs but I hope you get concept now and it helps you.
