How to Use V-Model In Quill.js In Vue 3?

To use v-model in Quill.js in Vue 3, you can bind the Quill editor instance to a Vue component using v-model. You first need to create a component for the Quill editor and set up a data property to store the editor instance. Then, use the v-model directive to bind the editor content to a data property in your Vue component. This way, any changes made in the Quill editor will be reflected in the data property and vice versa. Remember to also handle the input and change events in the Quill editor to update the data property accordingly.

How to create a controlled input with v-model in Quill.js?

To create a controlled input with v-model in Quill.js, you can use a combination of Quill editor's methods and Vue.js reactivity system.

Here's an example of how you can achieve this:

1. Define a data property in your Vue component to store the content of the Quill editor:

1
2
3

data() {
  return {
    quillContent: ''
  }
}

1. Initialize the Quill editor in a mounted hook of your Vue component:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

mounted() {
  this.quill = new Quill('#editor', {
    theme: 'snow',
    modules: {
      toolbar: [
        ['bold', 'italic', 'underline']
      ]
    }
  });

  this.quill.on('text-change', () => {
    this.quillContent = this.quill.root.innerHTML;
  });
}

1. Bind the Quill editor's content to the data property using v-model in your template:

1

<div id="editor" v-model="quillContent"></div>

Now, whenever the content of the Quill editor changes, the quillContent data property will be updated accordingly. You can also set the initial content of the Quill editor by setting the quillContent data property in your Vue component.

What is the syntax for v-model in Quill.js?

In Quill.js, the syntax for using v-model is:

1

<quill-editor v-model="content"></quill-editor>

In this example, the content data property will be automatically bound to the Quill editor component. Any changes made in the editor will be reflected in the content data property and vice versa.

What are the performance considerations when using v-model in Quill.js?

When using v-model with Quill.js, there are a few performance considerations to keep in mind:

1. Memory usage: Quill.js stores the entire editor contents in memory, so if you are working with very large documents or multiple instances of the editor on a single page, it can consume a significant amount of memory. This can affect the overall performance of your application, especially on devices with limited resources.
2. Rendering speed: Updating the editor contents through the v-model binding can trigger a re-render of the editor UI, which can be resource-intensive, especially for complex documents or frequent updates. This can lead to slower response times and potential lag in user interactions.
3. DOM manipulation: Quill.js dynamically inserts and modifies DOM elements to render the editor content, and frequent updates through v-model can result in increased DOM manipulation. This can impact performance, especially on older browsers or devices with slower processors.

To mitigate these performance considerations, consider the following strategies:

• Optimize your document structure: Try to keep your document structure as simple as possible to reduce memory usage and rendering time. Avoid unnecessary formatting and nesting, and use Quill.js features like formats, styles, and modules judiciously.
• Limit the use of v-model updates: Instead of triggering frequent updates through v-model, batch your changes and only update the editor content when necessary. This can help reduce the number of re-renders and DOM manipulations.
• Use virtual scrolling: If you are working with large documents, consider implementing virtual scrolling to only render the visible portion of the document. This can help improve overall performance by reducing the amount of content that needs to be rendered and stored in memory.
• Monitor performance: Keep an eye on the performance metrics of your application when using v-model with Quill.js. Use browser developer tools and profiling tools to identify potential bottlenecks and optimize your code accordingly.
