How to Fix Absolute Imports in TypeScript?
Introduction When working on TypeScript projects, organizing and managing module dependencies is essential for maintaining a clean and scalable codebase. Absolute imports offer a convenient way to reference modules using a fixed path relative to the project's root directory. However, configuring and fixing absolute imports can sometimes be challenging, especially for beginners. In this tutorial, we will explore various scenarios where absolute imports may encounter issues and discuss practical solutions to resolve them. By the end, you'll understand how to fix absolute import problems in TypeScript effectively. Scenario 1: Missing TypeScript Configuration Before utilizing absolute imports, we must ensure that ...
Read MoreHow to draw Regular Polygon in TypeScript?
Regular polygons, such as squares, triangles, and hexagons, are fundamental shapes used in various applications and graphics. Drawing regular polygons programmatically can be useful in TypeScript, allowing you to create geometric shapes dynamically. In this tutorial, we will explore how to draw regular polygons in TypeScript by leveraging basic mathematical principles and the HTML5 canvas element. Syntax function drawRegularPolygon(ctx: CanvasRenderingContext2D, n: number, x: number, y: number, r: number): void { const angle = (Math.PI * 2) / n; ctx.beginPath(); ctx.moveTo(x + r, y); for (let i = 1; i
Read MoreObject - Oriented Terms Supported by TypeScript
Object-oriented programming (OOP) is a popular programming paradigm that has been widely adopted in the software development industry. OOP is based on the concept of objects, which are instances of classes that encapsulate data and behaviour. TypeScript, a statically typed superset of JavaScript, is designed to support the development of large-scale applications and is also an object-oriented programming language. In this article, we will explore the object-oriented terms supported by TypeScript. Below we discuss various object-oriented terms supported by TypeScript. Class In TypeScript, a class is a blueprint for creating objects that define a set of properties and methods that ...
Read MoreHow is Declaration Merging done in TypeScript?
Introduction TypeScript offers powerful features that enhance JavaScript development. One such feature is declaration merging, which allows developers to combine multiple declarations of the same entity into a single definition. This tutorial will introduce you to the concept of declaration merging in TypeScript and provide examples to help you understand its practical implementation. Declaration Merging Basics Declaration merging in TypeScript enables the compiler to merge multiple declarations for the same entity, such as interfaces, functions, classes, or enums. By merging declarations, you can extend existing types and add new properties, methods, or functionality. Let's explore the scenarios where declaration merging ...
Read MoreHow to compile few typescript files to single output js-file?
TypeScript is a strongly typed superset of JavaScript that compiles to plain JavaScript. TypeScript adds static type-checking, classes, and interfaces to the language, making writing and maintaining large-scale applications easier. TypeScript files are compiled into JavaScript files that can be run in any browser or server that supports JavaScript. This article will look at how to compile multiple TypeScript files into a single output js-file. We will start by looking at how to use the TypeScript compiler to compile multiple TypeScript files and then see how to use Webpack to bundle multiple TypeScript files into a single JavaScript file. Compiling ...
Read MoreCreating a 3D cube using canvas in HTML5
We can create a 3D cube using the element and JavaScript in HTML5. The following document defines a canvas element with a width and height of 400 pixels, and uses JavaScript to get the canvas context to draw on the canvas. The cube is drawn using three separate faces: the front face, the top face, and the right face. This element is helpful in rendering 2D and 3D graphics in web browsers. Another alternate method to create a 3D cube is by using CSS 3D transitions, which allows us to create and animate the 3D cube, and WebGL which ...
Read MoreHow to Count Array Items in Angular JS?
A well−liked JavaScript framework for creating dynamic web apps is AngularJS. It offers a variety of helpful array−related tools, such as ways to measure the number of items in an array. In this article, we'll look into using AngularJS to count the number of items in an array. Method 1: Using the length property Using the built−in length property is the quickest and most popular method to count the number of items in an array in AngularJS. The length property gives the array's total amount of items. Algorithm Start Define an array 'myArray' and assign it to a ...
Read MoreHow to call api using typescript?
In this tutorial, we will learn about calling APIs using TypeScript. TypeScript is a statically-typed superset of JavaScript that adds type checking to the language. It provides enhanced tooling and helps catch errors during development. When working with APIs, we often need to make HTTP requests to send data and retrieve information. TypeScript allows us to write clean and organized code while interacting with APIs, making it easier to handle responses and work with the returned data. Throughout this tutorial, we will explore different methods and libraries available in TypeScript for making API calls. We will focus on using the ...

Read MoreHow to Encode/Decode URL using AngularJS ?
Handling URLs, which are used to move between various web pages and parts, is a fundamental component of web development. Spaces, question marks, and ampersands, among other special characters, can cause problems in URLs when transmitted over the internet. For instance, certain web servers may behave unexpectedly if a URL contains a space, supposing it to be a separate command or argument. AngularJS is a popular JavaScript framework used for building single−page applications. It provides several built−in methods for URL encoding and decoding, making it easy for developers to handle URLs in their applications. We will explore different methods ...
