I have unfortunately had to make the decision that I a no longer able to maintain this project. I do think that this project still has merit and I would be happy to hand it over to someone who agrees. If you are interested, please let me know through the repo's discussion or drop me an email.
Vue GrapesJS Composables aims to provide a Vue composition friendly interface into GrapesJS by providing reactive objects for the relevant GrapesJS modules. It allows the developer to utilise the GrapesJS canvas, along with all of its functionality, inside a Vue project, and use the reactive objects to easily create a custom interface to manage the editor.
It does this by providing composables for GrapesJS modules that requires a UI. The composable returns a reactive object that provides realtime access to the objects managed by the module, along with any module functions that are also needed. See the API specification for more details on this.
Since there is an overlap between the functionality that GrapesJS and Vue provide, this project only includes modules that can not easily be replaced by pure Vue functionality, like panels. Likewise, only modules that provide access to dynamic state are included, excluding modules like commands. The core GrapesJS modules that are not included can still be accessed directly from the editor.
Please follow the instructions below to set your project up with Vue GrapesJS Composables.
Vue GrapesJS Composables includes GrapesJS. It is designed to be used as Vue composables and as such, can only be used in a Vue 3 project.
The Usage section in this Readme expects that you are have at least a basic understanding of all the modules in GrapesJS.
This package is simply installed as a dependency to a Vue 3 project. As such the steps are:
- Install Vue 3 using you preferred method/template.
- Install Vue GrapesJS Composables:
npm install vue-grapesjs-composables- or
yarn add vue-grapesjs-composables
All of Vue GrapesJS Composables is accessible as composables in Vue components.
To initialise GrapesJS, create a div with a ref in a component which will contain the canvas. From that component, call useGrapes in the setup function of that component. To Configure GrapesJS, provide the configuration object as defined in the GrapesJS API Reference. As with normal GrapesJS, the starting content can either be added in the canvas div or in the configuration object.
GrapesJS also requires a css file to handle the component highlighting. This is provided with Vue GrapesJS Composables and can be imported into main.js or the component containing the canvas from vue-grapesjs-composables/css/vue-grapes.css.
<template>
<div ref="canvas">
<h1>Hello world!</h1>
</div>
</template>
<script setup>
import { useGrapes } from 'vue-grapesjs-composables'
import 'vue-grapesjs-composables/css/vue-grapes.css'
// Use ref to determine container for the canvas
const canvas = ref(null)
// Pass GrapesJS configuration object to useGrapes
const grapes = useGrapes({
container: canvas,
fromElement: true,
})
</script>Note that Vue GrapesJS Composables by default removes all panels from the GrapesJS configuration and sets the height of the canvas to 100%. This aligns better with the notion that the management UI will be provided with Vue. This can however be overwritten if desired simply by providing the panels or height properties to the configuration object.
See useGrapes API specification for more details.
With GrapesJS initiated, the rest of the UI can be built with your own UI components utilising the rest of the composables as required. This means that the API specifications from GrapesJS still apply to each object. However, instead of listening to, and acting on events, and using getter functions, up-to-date Model attributes and Collection arrays are accessible directly from the reactive object. All other functions on the Model/Collection can still be used as normal.
Lets go through each of the available modules and see how we can implement them in Vue.
Configure the blocks as you would normally in the config object provided to useGrapes. Use useBlocks to access a reactive list of blocks and the methods required to handle the drag and drop. Simply render the list in a component and use the drag and drop functions on the dragstart and dragend events on each block.
See useBlocks API specification for more details.
<script setup>
import { useBlocks } from 'vue-grapesjs-composables'
// Provide the response from useGrapes as prop
const { grapes } = defineProps(['grapes'])
const blocksMgr = useBlocks(grapes)
</script>
<template>
<div class="block-list">
<div
v-for="block in blocksMgr.blocks"
:key="block.getId()"
@dragstart="blocksMgr.dragStart(block._model)"
@dragend="blocksMgr.dragStop()"
v-html="block.getLabel()"
draggable="true"
></div>
</div>
</template>Components and component types are defined in the usual GrapesJS way.
The component that you mostly access and manipulate is the selected component. As such, access to a reactive representation of this component (meaning this will always be the up to date selected component) is available from the useSelectedComponent composable. From here you can do things like manage the component classes, traits, child components, etc. See the sections below for examples.
See useSelectedComponent API specification for more details.
The selected component includes a list of traits. Traits are defined in the component definition as usual. However, instead of defining trait types through a plugin, define a Vue component for each trait type. Then when rendering the traits of a component, render the relevant Vue component for each trait based on the type field.
Canvas.vue
<script setup>
import { useGrapes } from 'vue-grapesjs-composables'
import Traits from './Traits.vue'
const canvas = ref(null)
// Content is provided as part of the configuration to include Traits
const grapes = useGrapes({
container: canvas,
fromElement: true,
components: {
tagName: 'p',
content: 'Hello world!',
attributes: { 'data-counter': 1 },
traits: [
{
type: 'Counter',
name: 'data-counter',
label: 'Counter',
step: 2,
},
],
},
})
</script>
<template>
<div class="row">
<div class="col-9">
<div ref="canvas"></div>
</div>
<div class="col-3">
<Traits :grapes="grapes" />
</div>
</div>
</template>Traits.vue
<script setup>
import { useSelectedComponent } from 'vue-grapesjs-composables'
import Counter from './Counter.vue'
const components = { Counter }
const { grapes } = defineProps(['grapes'])
const selected = useSelectedComponent(grapes)
</script>
<template>
<div v-for="trait in selected.component.traits">
{{ trait.label }}:
<component :is="components[trait.type]" :trait="trait" />
</div>
</template>Counter.vue
<script setup>
const { trait } = defineProps(['trait'])
</script>
<template>
<span>
<button @click="trait.value = trait.value - trait.step">-</button>
{{ trait.value }}
<button @click="trait.value = trait.value + trait.step">+</button>
</span>
</template>In GrapesJS the style of a component is managed by determining the relevant CSS rule to edit, and then setting the style properties. The selected rule is dependent on the selected component, the activated classes and the selected state. As such, these are all available as reactive objects in Vue GrapesJS Composables.
As an alternative, a reactive list of all available CSS rules, with direct access to the css styling, is available.
A reactive array of the classes on the selected component are available by accessing the classes property on the selected component through the useSelectedComponent composable. This array provides methods for adding and removing classes and the active status can be set on each class.
See useSelectedComponent API specification for more details.
The available and selected states can be accessed with the useState composable. This provides a reactive object that includes an up-to-date list of all the states, the name of the selected state and a method to change the selected state.
See useState API specification for more details.
A reactive list of the properties on the selected Component or Rule is available through the useStyleProps composable. This provides a list of selectors, each containing a list of properties, along with methods to manage the property types.
To render the properties, create a component for each property type. This can include custom types. You can then dynamically render the relevant type for each component base on its type attribute.
See useStyleProps API specification for more details.
If a more customised experience for selecting or updating the CSS rules is required, a reactive list of CSS rules can be accessed through the useStyles composable. This returns a list of all CSS rules, the selected rule, and methods to manage the list of rules.
See useStyles API specification for more details.
Styling.vue
<script setup>
import { useSelectedComponent, useState, useStyleProps } from 'vue-grapesjs-composables'
// To dynamically select the property component, provide them in an object
// Only adding an example for number properties here
import NumberProp from './NumberProp.vue'
const props = {number: NumberProp}
// Get reactive GrapesJS objects
const { grapes } = defineProps(['grapes'])
const selected = useSelectedComponent(grapes)
const state = useState(grapes)
const styles = useStyleProps(grapes)
// Add class to selected component
function addClass(e) {
selected.component.addClass(e.target.newClass.value)
e.target.newClass.value = ''
}
</script>
<template>
<div>
<!-- Manage state -->
<label for="state">State:</label>
<select @change="state.select($event.target.value)" :value="props.state.selected">
<option value>- State -</option>
<option v-for="option in props.state.all" :key="option.name">
{{ option.name || 'No label' }}
</option>
</select>
</div>
<!-- Add class to selected component -->
<form @submit.prevent="addClass">
<label for="newClass">Add class:</label>
<input type="text" name="newClass" />
<button>+</button>
</form>
<!-- Manage classes on selected component -->
<div>
<span v-for="cls in component.classes">
<input type="checkbox" v-model="cls.active" />
{{ cls.label }}
<button @click="component.removeClass(cls.name)">-</button>,
</span>
</div>
<!-- Dynamically render relevant component for each property on selected component -->
<div v-for="sector in styles.sectors">
<h4>{{ sector.name }}</h4>
<component v-for="prop in sector.properties" :is="props[prop.type]" :prop="prop">
</div>
</template>NumberProp.vue
<script setup>
const { prop } = defineProps(['prop'])
</script>
<template>
<div>
<label for="pixels">{{ prop.name }}</label>
<div>
<input name="pixels" placeholder="auto" v-model.lazy="prop.value" />
<select v-model="prop.unit">
<option value>Select</option>
<option v-for="unit in prop.units">{{ unit }}</option>
</select>
</div>
</div>
</template>A hierarchical reactive representation of the component layers in the canvas is available through useLayers. This provides access to the wrapper component and all child components can be access through the components property on each component.
See useLayers API specification for more details.
ComponentTree.vue
<script setup>
import { useLayers } from 'vue-grapesjs-composables'
const { grapes } = defineProps(['grapes'])
const layers = useLayers(grapes)
</script>
<template>
<ul>
<li v-for="comp in layers.components" @click.stop="layers.select(comp._model)">
<strong>{{ comp.tagName }}</strong>
<span> - {{ comp.name }}</span>
<component-tree v-if="comp.components.length" :grapes="grapes" />
</li>
</ul>
</template>Resizing the canvas to model a specific device setting is still done by managing the devices in GrapesJS. A reactive interface in to these devices is provided by the useDevices composable. This includes a list of all devices with methods to manage the list, and the selected device with a method to select another device.
See useDevices API specification for more details.
<script>
import { useDevices } from 'vue-grapesjs-composables'
// Provide the response from useGrapes as prop
const { grapes } = defineProps(['grapes'])
const deviceMgr = useDevices(grapes)
</script>
<template>
<div>
<button
v-for="device in deviceMgr.devices"
:class="{ selected: device.id === deviceMgr.selected.id }"
@click="deviceMgr.select(device.id)"
>
{{ device.name }}
</button>
</div>
</template>Vue GrapesJS Composables allows you to replace the default asset manager with a custom one. To do this, call the useAssetManager composable. This provides a reactive object containing all the details on the state of the asset modal, along with methods to manage the assets.
After useAssetManager is called, GrapesJS will update the reactive object instead of opening the asset manager modal when an asset is requested. It is then up to you to build a modal using that object. Use the isOpen attribute of the modal to show it when needed.
See useAssetManager API specification for more details.
<script setup>
import { useAssetManager } from 'vue-grapesjs-composables'
// Provide the response from useGrapes as prop
const { grapes } = defineProps(['grapes'])
const assetMgr = useAssetManager(grapes)
// Select asset and close modal
function select(asset) {
assetMgr.modal.select(asset)
assetMgr.modal.close()
}
</script>
<template>
<!-- Only show modal if GrapesJS requires input from the asset manager -->
<div class="overlay" v-if="assetMgr.modal.isOpen">
<div class="modal">
<img
v-for="asset in assetMgr.assets"
:src="asset.src"
:alt="asset.name"
@click="select(asset)"
/>
<button @click="assetMgr.modal.close()">Close</button>
</div>
</div>
</template>Much like with the Asset Manager, you can replace the GrapesJS modal with a custom one. To do this, call the useModal composable which returns a reactive object containing all the modal details. Use this reactive object to create your own modal component and display this when the open attribute on the modal object is true. Make sure to use the close function to close the modal so that GrapesJS knows that the modal has been closed.
See useModal API specification for more details.
<script setup>
import { useModal } from 'vue-grapesjs-composables'
// Provide the response from useGrapes as prop
const { grapes } = defineProps(['grapes'])
const modal = useModal(grapes)
</script>
<template>
<div class="overlay">
<div class="modal">
<h1 v-html="modal.title"></h1>
<div v-html="modal.content"></div>
<button @click="modal.close()">Close</button>
</div>
</div>
</template>To access the content (html and css) created with GrapesJS, Vue GrapesJS Composables provides a reactive object through the useStorage composable. This object includes read only access to the entire content, along with a function to load new content. It is then up to you to sync the content with your data provider.
Note that loading new content replaces the existing content so for updates, make sure to pass the whole content and not just the changes. However, if you are making updates, consider if it might not be better to use the component or style interface.
See useStorage API specification for more details.
Above are all the GrapesJS modules, models, and functions that Vue GrapesJS Composables provides. This leaves multiple modules and parts of modules not available. The decision to only provide the above functionality is based on an estimate of where reactivity of GrapesJS collections and models makes most sense.
For instance, Pages have not been included because the assumption is that the page is managed by Vue which provides the relevant content through useStorage. Similarly, Commands have not been included because there is no state to be kept in sync with Vue.
However, There will undoubtedly be exceptions and needs for some users that have not been included. In this case, the core grapesJS API is also accessible. Since GrapesJS can only be initialized once the Vue components have been rendered, the GrapesJS API is accessible through the onInit callback provided by useGrapes. This callback receives the editor as a parameter and is called right after GrapesJS is initialized.
<script setup>
import { useGrapes } from 'vue-grapesjs-composables'
const canvas = ref(null)
const grapes = useGrapes({
container: canvas,
fromElement: true,
})
// Add a bold button to the Rich Text Editor
grapes.onInit(editor =>
editor.RichTextEditor.add('bold', {
icon: '<b>B</b>',
attributes: { title: 'Bold' },
result: rte => rte.exec('bold'),
})
)
</script>
