The Froala Vue WYSIWYG Editor is a powerful tool that allows developers to easily incorporate a rich text editing experience into their Vue.js applications. With its user-friendly interface and extensive customization options, the Froala html code writer provides a seamless editing experience for users.
We have covered the integration process of Froala and Vue before. However, in some applications, developers may need to initialize the Froala Vue WYSIWYG Editor by clicking on a certain element. By manually initializing the editor on click, developers can control when the editor appears on the page. This helps optimize your application load speed especially if you have more than one editor on the page.
In this article, we will guide you through the process of initializing the Froala Vue WYSIWYG Editor on click. We will cover the necessary prerequisites, step-by-step instructions, and customization options to help you make the most out of this powerful editing tool.
By the end of this guide, you will have a solid understanding of how to set up and initialize the editor on click. So let’s dive in and explore the benefits and importance of on-click initialization for the Froala Vue WYSIWYG Editor.
prerequisites
We assume you have a working knowledge of:
JavaScript (including some of the newer, ES2015 features)
Vue 3
How to use the terminal/command line
Node and npm
Create a simple Vue project.
To create a new Vue.js project, run the following commands.
npm install -g @vue/cli
vue create my-froala-vue-app
The above commands will install the Vue CLI globally on your machine and then create a new Vue project called “my-froala-vue-app”.
Install the Froala WYSIWYG Editor package.
Next, you need to install the Froala WYSIWYG Editor package. To do this, navigate to your project directory and run the following command:
cd my-froala-vue-app
npm install vue-froala-wysiwyg
This will install the Froala WYSIWYG Editor package and its dependencies into your project.
Import the Froala WYSIWYG Editor Component
To use the Froala WYSIWYG Editor in your Vue application, you need to import the component. Copy the following code into your “main.js” file.
import { createApp } from "vue";
import App from "./App.vue";
//Import Froala Editor plugins
import "froala-editor/js/plugins.pkgd.min.js";
// Import Froala Editor css files.
import "froala-editor/css/froala_editor.pkgd.min.css";
import "froala-editor/css/froala_style.min.css";
// Import Froala Editor component
import VueFroala from "vue-froala-wysiwyg";
const app = createApp(App);
app.use(VueFroala);
app.mount("#app");
This code imports the VueFroala component from the vue-froala-wysiwyg package and registers it. This allows you to use the Froala WYSIWYG Editor component in your Vue components.
Initialize the Froala Vue WYSIWYG Editor on Click
We will add the following code to the “app.vue” file.
<template>
<div id="app">
<h1>Vue adapter for the Froala WYSIWYG editor</h1>
<div class="sample">
<h2>Sample 4: Manual Initialization</h2>
<button class="manual" v-on:click="createEditor()" v-if="!showEditor">
Initialize Editor
</button>
<button v-on:click="destroyEditor()" v-if="showEditor">
Close Editor
</button>
<button v-on:click="deleteAll()" v-if="showEditor">Delete All</button>
<froala
id="sample5"
:onManualControllerReady="initialize"
v-model:value="sample3Text"
>
<template v-slot>
<div>
Check out the
<a href="https://www.froala.com/wysiwyg-editor">Froala Editor</a>
</div>
</template>
</froala>
</div>
</div>
</template>
<script>
export default {
name: "app",
data() {
return {
// Sample 4
sample3Text: null,
initControls: null,
showEditor: false,
deleteAll: null,
destroyEditor: () => {
this.initControls.destroy();
this.showEditor = false;
},
createEditor: () => {
this.initControls.initialize();
this.showEditor = true;
},
initialize: (initControls) => {
this.initControls = initControls;
this.deleteAll = () => {
this.initControls.getEditor().html.set("");
this.initControls.getEditor().undo.reset();
this.initControls.getEditor().undo.saveStep();
};
},
};
},
created() {},
};
</script>
<style>
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
color: #2c3e50;
margin-top: 60px;
}
body {
padding: 20px;
}
.sample {
padding-bottom: 50px;
margin-left: 30px;
border-top: 1px solid lightgray;
}
.manual {
margin-bottom: 20px;
}
.button {
margin-left: 5px;
}
</style>
Let’s break down the code step by step:
The code above defines three buttons: one for initializing the editor when it is not loaded on the page, and the other two buttons appear when the editor is shown. One button is for destroying the editor, and the other is used to clear the editor’s contents.
<h2>Sample 4: Manual Initialization</h2>
<button class="manual" v-on:click="createEditor()" v-if="!showEditor">
Initialize Editor
</button>
<button v-on:click="destroyEditor()" v-if="showEditor">
Close Editor
</button>
<button v-on:click="deleteAll()" v-if="showEditor">Delete All</button>
The showEditor is a data property that determines whether the editor is currently shown or not. It is initially set to false. The createEditor method is called when the “Initialize Editor” button is clicked, and it sets showEditor to true and initializes the editor. The destroyEditor method is called when the “Close Editor” button is clicked, and it destroys the editor and sets showEditor back to false. The deleteAll method is called when the “Delete All” button is clicked, and it clears the editor contents.
Our “app.vue” code also includes the Froala Vue component. It has an id of sample5 and a v-model binding to the sample3Text data property. This :onManualControllerReady is used to bind the initialize method to the Froala editor’s manual controller. This allows us to access the editor’s methods and perform actions such as clearing the editor’s contents.
<froala
id="sample5"
:onManualControllerReady="initialize"
v-model:value="sample3Text"
>
The initialize method is called when the editor is initialized, and it receives the initControls object as a parameter. Developers can obtain instances of the FroalaEditor object by using the getEditor() method of the initControls object. This allows them to easily access and utilize any Froala API method.
<script>
export default {
name: "app",
data() {
return {
// Sample 4
sample3Text: null,
initControls: null,
showEditor: false,
deleteAll: null,
destroyEditor: () => {
this.initControls.destroy();
this.showEditor = false;
},
createEditor: () => {
this.initControls.initialize();
this.showEditor = true;
},
initialize: (initControls) => {
this.initControls = initControls;
this.deleteAll = () => {
this.initControls.getEditor().html.set("");
this.initControls.getEditor().undo.reset();
this.initControls.getEditor().undo.saveStep();
};
},
};
},
created() {},
};
Finally, we have a template block inside the Froala component where we can add additional HTML content. In this example, we have simple text and a link to the Froala Editor website.
<template v-slot>
<div>
Check out the
<a href="https://www.froala.com/wysiwyg-editor">Froala Editor</a>
</div>
</template>
That’s it! You have now created a simple Vue project with the Froala html code writer integrated. You can now run your Vue project and see the Froala Editor in action.
Run the Vue App
To run the Vue app and see the Froala Vue WYSIWYG Editor in action, navigate to your project directory and run the following command:
npm run serve
This will start the development server at http://localhost:8080
The benefits of loading Froala on click
Loading the Froala Vue WYSIWYG editor on click offers several benefits for developers. It helps improve the initial loading time of the webpage. By deferring the loading of the editor until it is actually needed, developers can ensure that their web pages load quickly and efficiently. This can lead to a better user experience, as visitors won’t have to wait for the editor to load if they don’t plan on using it.
Additionally, loading the Froala editor on click allows developers to save resources and optimize performance. Since the editor is only loaded when necessary, it doesn’t consume unnecessary memory or processing power. This can help improve the overall performance of the webpage and prevent any unnecessary strain on the user’s device.
Moreover, loading the Froala editor on click provides a more seamless and intuitive user experience. Instead of having the editor visible at all times, it only appears when the user explicitly chooses to use it.

User experience is the most essential factor to consider when creating an application that allows file or image uploads. This is why you need to follow best practices when adding an image uploader for a website.
In this article, we will explore the eight best practices to add an image uploader to your website.
Key takeaways
A well-designed image uploader for a website improves user experience, performance, and reliability across devices.
Use drag-and-drop interfaces, progress indicators, and previews to create a simple and intuitive UI.
Support multiple file types like JPEG, PNG, GIF, WebP, and offer automatic resizing or compression for better performance.
Implement strong security practices, including file type validation, server-side checks, and metadata sanitization.
Use asynchronous uploads, chunked file support, and cloud storage to optimize upload speed and stability.
Provide real-time visual feedback to users through upload progress, success confirmations, and error messaging.
Design your image upload tool to be fully responsive and mobile-friendly, with support for camera access and low-bandwidth handling.
Enhance user experience with built-in image processing features like cropping, rotation, optimization, and optional filters.
Store files using cloud-based solutions with redundancy, smart naming conventions, and consider DAM system integration for scaling.
Tools like the Filestack image uploader offer these capabilities out of the box, saving time and boosting reliability.
1. Prioritize a simple and intuitive user interface
The success of an image uploader often starts with how easy it is for users to interact with it. A clean, intuitive interface ensures that users can upload images without confusion or frustration.
Drag-and-drop functionality is now a baseline expectation. The feature provides users with a convenient way to upload images by allowing them to drag and drop files into a designated area. It creates a contemporary and effortless upload experience.
The process requires clear call-to-action buttons, which should be labeled as “Upload Image” or “Choose File”. The visual elements should be prominent while using simple language to guide users to their next steps.
Visual feedback — like real-time progress bars, success messages, or thumbnail previews — gives users confidence that their image is uploading properly. The system also reduces uncertainty, especially for larger files or slower connections.
Designing with clarity and simplicity in mind helps create a frictionless experience that users appreciate and trust.
This example shows how to add a user-friendly image uploader to your website with the advanced file uploader by Filestack. This simple and intuitive file upload UI improves the user experience with features like drag-and-drop functionality, progress bar, upload buttons, etc.
const client = filestack.init('YOUR_API_KEY'); // Replace with your real API key
function openPicker() {
client.picker({
accept: ['image/*'],
onUploadDone: (res) => {
const imageUrl = res.filesUploaded[0].url;
displayImage(imageUrl);
}
}).open();
}

2. Support multiple file formats and sizes
To ensure your image uploader is versatile and user-friendly, it’s important to support a variety of popular file formats. The most common formats include JPEG, PNG, GIF, and WebP, which cover most use cases from photos and illustrations to animated content.
File size restrictions are just as important. Large images can slow down performance for both the user and your server. The implementation of upload limits helps to preserve speed performance while enhancing system responsiveness and decreasing bandwidth consumption.
To strike the right balance between quality and performance, offer automatic resizing or compression during upload. The technical specifications are handled by you, so users don’t need to worry about them while your site remains fast and efficient.
3. Implement robust security measures
Image uploaders serve as primary entry points for malicious attacks, so security needs to be the top priority. Your uploader becomes vulnerable to malware, code injection, and data breaches when it lacks appropriate security measures.
The first step involves file type validation to accept only JPEG, PNG, or WebP formats, which are considered safe and supported formats. This feature stops the execution of files and image disguises that could contain malicious content.
Server-side validation needs to be used in conjunction with client-side validation. The client-side validation process lacks security, so you need to perform file type verification, size checks, and integrity checks again on the server before storing or processing them.
Finally, don’t overlook metadata and file names. All user-uploaded content must undergo sanitization to remove dangerous scripts and commands that pose threats of injection attacks and directory traversal exploits.
These measures will safeguard both your users and your infrastructure from preventable risks.
Secure image upload example using Filestack + Express (server-side)
Here is an example of a secure image upload on the server-side using Filestack and Express. See the complete example in our GitHub repository.
// Install dependencies:
// npm install express multer sanitize-filename filestack-js
const express = require('express');
const multer = require('multer');
const sanitize = require('sanitize-filename');
const fs = require('fs');
const path = require('path');
const filestack = require('filestack-js');
const app = express();
const port = 3000;
// Initialize Filestack client
const client = filestack.init('YOUR_FILESTACK_API_KEY');
// Acceptable MIME types
const allowedTypes = ['image/jpeg', 'image/png', 'image/webp'];
// Set up Multer storage (in memory)
const storage = multer.memoryStorage();
const upload = multer({
storage: storage,
fileFilter: (req, file, cb) => {
// Validate MIME type
if (allowedTypes.includes(file.mimetype)) {
cb(null, true);
} else {
cb(new Error('Unsupported file type'), false);
}
},
limits: { fileSize: 5 * 1024 * 1024 } // Limit: 5MB
});
// Image upload route
app.post('/upload', upload.single('image'), async (req, res) => {
try {
// Sanitize filename
const originalName = sanitize(req.file.originalname);
// Upload to Filestack
const result = await client.upload(req.file.buffer, {
filename: originalName,
mimetype: req.file.mimetype
});
res.json({
message: 'Upload successful!',
url: result.url
});
} catch (err) {
res.status(400).json({ error: err.message });
}
});
// Start server
app.listen(port, () => {
console.log(`Server running at http://localhost:${port}`);
});
4. Optimize Upload Speed and Performance
The speed is a crucial factor when uploading images. Users need uploads to operate at high speeds while delivering smooth performance, particularly when dealing with large files or multiple images.
Begin by using AJAX or APIs to implement asynchronous uploads. The background upload feature enables users to upload files without interrupting their experience or forcing them to reload the page.
Next, leverage CDNs or cloud storage services like Amazon S3 or Google Cloud Storage. The services offer quick upload features together with dependable storage solutions that allow users to select their storage capacity needs.
The system enables chunked uploads for large files through a process that divides files into smaller parts, which are uploaded individually. This prevents timeouts, allows resuming interrupted uploads, and improves overall stability.
The system requires an update to allow users to upload multiple files at the same time, which would improve the efficiency of users who need to upload multiple images simultaneously.
The following simple example demonstrates how to upload images using the Filestack File Picker API, enabling background (asynchronous) uploads and allowing multiple image uploads.
// Replace with your actual Filestack API key
const client = filestack.init('YOUR_FILESTACK_API_KEY');
document.getElementById('uploadBtn').addEventListener('click', () => {
client.picker({
accept: ['image/*'], // Accept all image types
maxFiles: 5, // Allow multiple uploads
uploadInBackground: true // Enable background upload
}).open();
});
The combination of these performance tactics leads to a faster and more reliable uploading process.
See the complete example in our GitHub repository.

5. Provide real-time feedback to users
Real-time feedback is one of the most important ways to build user trust during the upload process. Users require instant verification that the image upload function is working correctly.
Begin by showing progress indicators along with the remaining estimated time. A basic loading bar or percentage indicator shows users that their upload continues in progress, particularly useful for both slow network speeds and big file transfers.
Next, include clear error messages for unsupported file formats or files that exceed size limits. Instead of leaving users guessing, tell them exactly what went wrong and how to fix it (e.g., “Only PNG or JPEG files under 5MB are allowed”).
Finally, offer thumbnails or image previews to verify you have selected the correct image(s) before the uploading process is completed. Also, show users instant visual confirmation of successful file uploads, which removes confusion and prevents them from re-uploading files.
When you integrate the Filetsack image uploader to your website, you don’t have to think about these indicators. It comes with these features, which enable you to add a few lines of coding. The screenshots below from the previous example show you how the Filestack image uploader provides real-time feedback to the users.

The above example shows the clear error messages and the thumbnails before uploading the image to the website.
Filetsack image upload API also comes with an in-built progress indicator. These built-in image upload tool features save development time significantly.

The feedback system you provide enables users to experience a more open and reassuring process.
6. Ensure mobile-friendliness
The ongoing rise of mobile usage requires your image uploader to function perfectly across all screen sizes and mobile platforms.
Start with responsive upload forms. The upload interface should have buttons, input fields, and drop zones that automatically resize when users switch to smaller screens and use touch interactions. The design should use flexible layouts instead of fixed widths because they automatically adjust to different viewports.

Users in the modern era want to take photos directly from their mobile devices. Native device integrations and the accept=”image/*” capture=”environment” attribute in <input> elements should be used to support camera access. The upload process becomes more efficient for users because the system reduces the number of required steps.
Finally, be mindful of lower bandwidth environments. Implement lightweight interfaces, show upload progress clearly, and minimize file size through compression or image optimization to ensure smooth performance on slower connections.
A mobile-friendly image uploader provides better accessibility while boosting user engagement and maintaining reliable site functionality for all users, regardless of their device choice.
7. Integrate image processing features
Your uploader becomes more functional and user-friendly when you implement image processing features directly. The integration of image processing capabilities eliminates the requirement for external editing tools while ensuring image optimization occurs before server storage.
Your application should enable users to perform basic image transformations, including cropping, resizing, and rotation, before they upload their files. Users gain better control over their content presentation through this feature, which also helps prevent problems with incorrect image orientation and large file sizes.
The next step involves implementing automatic optimization to enhance system performance. The combination of image compression with WebP format conversion and resolution reduction helps websites load faster, particularly when they contain numerous images.
Your application should provide users with the option to enhance their images through filters, brightness/contrast adjustment, and simple markup tools. The features prove particularly useful for e-commerce sites and platforms that handle user profile uploads and content creation applications, which require high-quality visuals.
The advanced file uploader from Filestack provides integrated image transformation capabilities, which require minimal setup for implementation.

8. Store images efficiently and reliably
The proper storage methods for uploaded images guarantee their accessibility, organization, and security as your application or website grows in size.
The first step involves implementing standard naming rules and directory arrangements. The system requires unique descriptive file names (e.g., product-123-front.webp instead of image1.png), which should be stored in folders that use date, user ID, or content type as their organization system. The system provides easy retrieval capabilities and protects against future confusion and overwrites.
Select cloud storage solutions that provide built-in backup and redundancy features, such as Amazon S3 or Filestack’s integrated storage. The services provide reliability alongside scalability and peace of mind because they maintain asset safety and accessibility even when one node fails.
The implementation of a Digital Asset Management (DAM) system becomes necessary when you need to handle large numbers of assets. A DAM system enables the efficient management of media libraries through organization, versioning, tagging, and access control, which facilitates content-heavy platform scalability.
Smart storage choices decrease maintenance requirements while providing instant image access throughout your application.
Conclusion
The implementation of an image uploader on your website represents a strategic decision that directly affects user satisfaction, operational efficiency, and engagement levels. The different best practices, which support multiple file types, mobile optimization, and security protection, work together to create a professional upload experience.
The implementation of these eight practices leads to an image uploader that functions properly while delivering fast performance, security features, and scalability. Your project will achieve long-term success through proper upload strategy investment, regardless of whether you develop a blog, e-commerce platform, or SaaS application.
