        mounted() {
            console.log('Component mounted.')

Your components are probably in the same folder. In your component formToDo.vue: Change this:

import modalAlert from './components/modalAlert.vue';

To this:

import modalAlert from './modalAlert.vue';

To solve the other issue, as @ambianBeing suggested, your component formToDo.vue must have root element to be able to add child component inside it.

<template>
<div> <!-- this is the root -->
    <modal-alert></modal-alert>
</div>
</template>
