How to flip textbox horizontally using FabricJS?
In this tutorial, we will learn how to flip a Textbox object horizontally using FabricJS. We can customize, stretch or move the text written in the text box. In order to create a textbox, we have to create an instance of the Fabric.Textbox class and add it to the canvas. We can flip the text box object horizontally using the FlipX property.
Syntax
new fabric.Textbox(text: String, { flipX: Boolean }: Object)Parameters
text - This parameter accepts a string, which is We are going to use the text string we want to display in our text box.
Options (optional) - This parameter is an object that provides additional customization of our text box. Using this parameter, you can change object-related properties such as color, cursor, stroke width, and many other properties. flipX is a property of the object.
ul>##flipX - This property accepts a Boolean value, allows us to flip the object horizontally.
Option Key
Passing FlipX as key with "false" value
Let's look at a code example , which shows us the default orientation of textbox objects in FabricJS. Since we passed a False value to theflipX property, the text will not flip horizontally.

<h2>Passing flipX as key with a "false" value</h2>
<p>You can see that the text has not flipped horizontally</p>
<canvas id="canvas"></canvas>
<script>
// Initiate a canvas instance
var canvas = new fabric.Canvas("canvas");
canvas.setWidth(document.body.scrollWidth);
canvas.setHeight(250);
// Initiate a textbox object
var textbox = new fabric.Textbox("Each day provides its own gifts.", {
backgroundColor: "#e3dac9",
width: 400,
left: 70,
top: 70,
flipX: false,
});
// Create gradient fill
textbox.set(
"fill",
new fabric.Gradient({
type: "linear",
coords: { x1: 0, y1: 0, x2: 100, y2: 0 },
colorStops: [
{ offset: 0, color: "#545a2c" },
{ offset: 1, color: "#6495ed" },
],
})
);
// Add it to the canvas
canvas.add(textbox);
</script>
</body>
</html>Passing the FlipX attribute as a key with a value of "true"
In this example we have a width of 200px The text box object has a horizontal linear gradient fill. When we apply the flipX property to the text box object, the text flips horizontally, so we see the gradient and the text flip as well.<!DOCTYPE html>

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
The Evolution of JavaScript: Current Trends and Future Prospects
Apr 10, 2025 am 09:33 AM
The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
JavaScript Engines: Comparing Implementations
Apr 13, 2025 am 12:05 AM
Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
JavaScript: Exploring the Versatility of a Web Language
Apr 11, 2025 am 12:01 AM
JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
Python vs. JavaScript: The Learning Curve and Ease of Use
Apr 16, 2025 am 12:12 AM
Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

From C/C to JavaScript: How It All Works
Apr 14, 2025 am 12:05 AM
The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
