Guide on developing a Vue modal for transferring user input to a separate component

I have been working on creating a modal component that allows users to input data and then displays it in another component. For example, the user is prompted to enter their first and last name in a modal component (Modal.vue). Once the user saves this information using a submit method on the modal, it is displayed in another component (InputItem.vue).

Currently, my project consists of several components: CreateEvent.vue, Modal.vue, EventItem.vue, EventsList.vue, and app.vue. I have implemented CRUD functionality successfully without the modal component, but when I try to integrate the modal, I start facing difficulties.

I would appreciate any guidance or assistance you can provide to help me navigate through this challenge!

Modal.vue

<template>
  <transition name="modal-fade">
    <div class="modal-backdrop">
      <div
        class="modal"
        role="dialog"
        aria-labelledby="modalTitle"
        aria-describedby="modalDescription"
      >
       <!--- Modal template code goes here --->
      </div>
    </div>
  </transition>
</template>

<script>
export default {
  name: 'modal',
  data() {
    return {
      newTodo: '',
      newEmoji: '',
      idForTodo: this.todos.length + 1
    }
  },
  methods: {
   <!--- Modal methods go here --->
  }
}
</script>

To improve the modal component, it is suggested that instead of directly pushing values into the todos array, emit the values. This emitted data can then be listened for by the parent component (App.vue).

An example implementation could look like the following:

Modal.vue

<template>
   ...
// header
<section class="modal-body" id="modalDescription">
  <slot name="body">
    <div @keyup.enter="addTodo">
      ...
    </div>
    <button @click="handleModalSubmit">Create Event</button>
  ...
  //footer
  ...
</template>

<script>
export default {
  ...
  data() {
    ...
  },
  methods: {
    ...,
    handleModalSubmit() {
      this.$emit('todos-have-been-submitted', this.todos);
    },
    addTodo() {
      ...
      this.todos.push({
        id: this.idForTodo,
        title: this.newTodo,
        emoji: this.newEmoji
      })
      ...
    }
  }
}
</script>

App.vue

<template>
  ...
  <Modal
    @todos-have-been-submitted="handleTodoSubmission" //listen for the 'todos-have-been-submitted' event and trigger handleTodoSubmission method upon detection
  />
  <Events 
    :todos="todos" // pass todos as a prop to the Events component
  />
  ...
</template>

<script>
import Events from './components/Events'
import Modal from './components/Modal'

export default {
  name: 'App',
  components: {
    Events,
    Modal
  },
  data() {
    return {
    ...,
      todos: []
    }
  },
  methods: {
    ...,
    handleTodoSubmission(todos) {
      this.todos = [...todos];
    }
  }
}
</script>
