The fabric.Text object of Fabric.JS is used to change the corner style of a canvas-type text. Text class of Fabric.js provides the text abstraction by using the fabric.Text object, which allows us to work with text in an object-oriented way. Comparing to the canvas class the Text class provides the rich functionality. The text object contains the different properties, but to change the style of corner and rendering the text of canvas can be done using one of the style property i.e., cornerStyle. If the cornerStyle is default then it returns rect, otherwise the value is defined as a circle ... Read More

Text class of Fabric.js provides the text abstraction by using the fabric.Text object, which allows us to work with text in an object-oriented way. Comparing to the canvas class the Text class provides the rich functionality. The text object contains the different properties, but to change the font-weight of a text canvas can be done using one of the font property i.e., fontWeight. The fontWeight property of a Fabric.js Text object specifies the weight or thickness of the text characters. It can be used ... Read More

Text class of Fabric.js provides the text abstraction by using the fabric.Text object, which allows us to work with text in an object-oriented way. Comparing to the canvas class the Text class provides the rich functionality. The text object contains the different properties, but to change the character spacing of a text canvas can be done using one of the property i.e., charSpacing. This property sets the spacing between characters in pixels. You can also use the setCharSpacing method to changing the spacing of ... Read More

The Window object, known as the Global TypeScript object, represents the current web page in a browser window. The location, history, and document of the current page, as well as other methods and attributes, can all be accessed and controlled using this method. The Navigator object is a property of the Window object. It contains information about the browser and device used to visit the website, including the user agent, platform, and language. TypeScript's Window.navigator object can receive information about the device browser and perform operations on those objects. The Window and Navigator objects can be used in TypeScript by ...

The programming language TypeScript is based on JavaScript and is strongly typed, object-oriented, and compiled. The language is improved with tools like static typing, classes, and interfaces that help with early error detection and make JavaScript more manageable. One of TypeScript's features is the ability to enforce the types of an object's indexed members, and this process is also referred to as an index signature. An index signature is a set of key-value pairs describing the many properties an object may have. The type of the property name and the type of the property value are specified, respectively, using the ... Read More
Before developing the actual generic class, let's first learn about the Generic class. A TypeScript class known as generic may deal with numerous types of data. It is a variety of arguments and is displayed using angle brackets (). This represents the kind of data the class will use to achieve this. The type argument can then be used in the class's properties and functions to make the class flexible and reusable with other data types. We will be briefing a little bit. Suppose, in an example, the type parameter is denoted as "T" and the property "value" of the ... Read More
The mouseover event is used in the JavaScript code to change the color of background to an elements of HTML. We also want to restore the color to blue after removing our mouse from the element. As a result, we have also used the mouseout event. This will happen when we remove our mouse pointer from the element. getElementById() produces an object of element which represents the element whose id attribute matches the provided string. Because element IDs must be unique if supplied, they're a convenient method to rapidly retrieve a single element. The addEventListener() function is employed to ... Read More
We can use the try-catch statements to solve errors in TypeScript. Sometimes, we require adding more than one try-catch block in the code to handle multiple errors. When we add multiple try-catch statements in the code, the code becomes unreadable, and it becomes a headache for developers to refactor. In this tutorial, we will learn to convert too many try-catch blocks into a single try-catch block which can manage multiple errors. Syntax Users can follow the syntax below to use the single try-catch block in TypeScript. try { throw new Error("error_message"); // this code ... Read More
Asynchronous programming allows us to perform multiple tasks parallelly. We can use the async/await keyword to make the function asynchronous. Before we start, let’s learn the need for asynchronous programming and function. It takes some time to respond when we fetch data from the API. Now, think we need to use the results in our app, which we get from API. The single-threaded programming language like TypeScript and JavaScript never stops the execution of the code. So, It doesn’t wait for the response of the API and starts performing some operation on null values. When we make the function asynchronous, ... Read More
