Edit View ​

Frontend Edit Views are Vue components generated for every module to display a form and relation widgets for editing or creating entities. They integrate with module-specific state management to handle data loading, submission, and dynamic UI behavior based on whether you are editing an existing entity or creating a new one.

Let's look at an example of a generated Edit View for the Recipe module:

vue
<template>
	<Header :title="isEdit ? 'Edit Recipe' : 'Create Recipe'" />
	<HeaderLoader :is-loading="loaders.size > 0" />
	<Container class="edit">
		<Form
			:id="route.params.id as string"
			@start-loading="loaders.add('form')"
			@stop-loading="loaders.delete('form')"
			@deleted="router.push({ name: 'recipes-list' })" />
		<StepsRelationWidget
			v-if="isEdit"
			:recipe-id="route.params.id as string"
			@start-loading="loaders.add('Steps')"
			@stop-loading="loaders.delete('Steps')" />
	</Container>
</template>

<script setup lang="ts">
import { reactive, computed } from 'vue'
import { useRoute, useRouter } from 'vue-router'
import Header from '@/components/Header.vue'
import Form from './components/Form.vue'
import HeaderLoader from '@/components/HeaderLoader.vue'
import Container from '@/components/Container.vue'
import StepsRelationWidget from './components/StepsRelationWidget.vue'

const route = useRoute()
const router = useRouter()
const isEdit = computed(() => route.name === 'recipes-edit')
const loaders = reactive(new Set<string>())
</script>

<style lang="scss" scoped>
.edit {
	display: grid;
	grid-template-columns: repeat(auto-fill, minmax(500px, 1fr));
	gap: 20px;
	justify-items: center;
	align-items: start;
}
</style>

Dynamic Title & Header ​

The <Header> component displays a dynamic title that changes based on the view mode. It shows "Edit Recipe" when the component is in edit mode, and "Create Recipe" otherwise. The mode is determined by the computed isEdit property, which inspects the current route name.

Progress Indicator ​

A <HeaderLoader> component is conditionally rendered when there are active loading operations. The reactive loaders set tracks the loading state for different components (e.g., form submission or relation updates). As long as loaders.size is greater than zero, the header loader appears to provide visual feedback to the user.

Form & Relation Widgets ​

Within a <Container>, the view renders two main components:

  • Form: This component is responsible for both creating new recipes and editing existing ones. It receives:

    • The recipe ID (when editing) via the :id prop. The form automatically determines if it's in edit mode based on whether the id prop is set.

    It also emits events for managing loading states:

    • @start-loading and @stop-loading to add or remove loading flags (e.g., for the form).
    • @deleted to redirect the user back to the recipes list after deletion.

  • RelationWidget: Rendered only when editing an existing recipe (v-if="isEdit"), this widget manages related data—in this case, the steps associated with the recipe. It also utilizes loading events to integrate with the overall loading state.

State Management ​

The component uses Vue’s Composition API for state management:

  • Route & Navigation: The useRoute and useRouter hooks provide access to route parameters and navigation methods.
  • Mode Detection: The isEdit computed property determines if the current route corresponds to an edit view (i.e., recipes-edit), otherwise the form is in create mode.
  • Loading State: A reactive loaders set tracks different loading states within the view. This approach allows multiple components to contribute to the global loading indicator seamlessly.

Summary ​

This generated Edit View component provides a powerful yet streamlined interface for managing entity data. With dynamic headers, integrated progress indicators, and modular components for form and relation management, it enables developers to focus on business logic while maintaining a consistent and robust UI.
