What is CoffeeScript all about?

CoffeeScript: A concise alternative to JavaScript? Want to know what CoffeeScript is? This video will quickly interpret it for you! Paul Annesley, the lead developer of SitePoint, worked with me to make this video for you. The birth of CoffeeScript is said to have originated from those who are tired of JavaScript syntax, and it may even help those who don’t understand how JavaScript works in the underlying form of writing more efficient code, because its process of compiling to JavaScript does a pretty good job in performance. Do you agree? Watch the video and leave your comments! open

Introduction to the HTML5 WebSockets API

HTML5 introduces many novel APIs, including WebSocket. WebSocket allows developers to create powerful real-time applications by establishing socket connections between the browser and the server. In other words, due to the existence of persistent connections, clients and servers can exchange data at any time. This tutorial will explain how to create a real-time web application using WebSocket. Key Points The WebSocket API introduced in HTML5 allows developers to create real-time applications by establishing persistent socket connections between the browser and the server, allowing clients and servers to exchange data at any time. Opening a WebSocket connection is very simple, you only need to call WebS

Implementing Push Technology Using Server-Sent Events

Core points The Server-Sent Events (SSE) API implements push technology, and data is streamed to the client through continuous open connections, avoiding the overhead of repeatedly establishing new connections. Unlike WebSockets that allow bidirectional communication, SSE only allows the server to push messages to the client. However, SSE has certain advantages, such as support for custom message types and automatic reconnection and disconnection. Clients can handle various event types in the event stream by implementing named events. In addition, the onerror event handler of EventSource can be used to handle errors, and the client can call close() at any time

Getting Started With SCSS-Lint

SCSS-Lint: A tool to keep Sass code tidy and consistent This article will explain how to use SCSS-Lint, a powerful Ruby gem tool, to maintain neatness and consistency of the Sass code base. It does this by tagging suspicious usage and ensuring the stylesheet is easy to read. Core points: SCSS-Lint is a powerful Ruby gem tool that helps maintain neatness and consistency of the Sass code base by tagging suspicious usage and ensuring stylesheets are easy to read. Before use, you need to install it, and the command line tool is called scss-lint. The configuration of SCSS-Lint involves defining the rules to be followed through the YAML file in the project root directory. This file is usually named

Creating HTML Templates with Mustache.js

Web applications usually use MVC architecture to separate business logic from presentation views. Complex projects involve a large number of client HTML that uses JavaScript operations, which can be difficult to maintain. In this case, we can use a template system to improve reusability and simplify view management tasks. Mustache.js provides a well-documented template system that can be used to manage templates. Moreover, since Mustache supports multiple languages, we do not need to use a separate template system on the server side. This article describes the basics of using Mustache. Key Points Mustache.js is a well-documented template system that can be used to manage complex

Using @error responsibly in Sass

Key Points The @error directive in Sass is a powerful tool to control author input and throw errors when problems occur, which is more effective than allowing compiler failures. For older versions of Sass that do not support @error, you can use the @warn directive instead. To ensure that the compiler still crashes when an error occurs, a hybrid macro can be created that triggers a compilation error after a warning. The feature-exists('at-error') function can be used to check whether @error is supported. If not supported, use the @warn directive and then use a function without the @return statement to crash the compiler. The log function can be used in other functions.

Sass Maps vs. Nested Lists

Core points Sass maps and nested lists are both data structures in Sass, and mappings were introduced in Sass 3.3. Mapping provides key-value pairs that allow for more complex data storage, while nested lists are simpler structures that can save complex data, but lack key-value pairing. Despite the added complexity of mapping, they become popular because of their ability to store a variety of data (such as breakpoint widths, color values, grid layouts, type proportions, and other responsive typography details). On the other hand, nested lists are more practical due to their simplicity and less input. One of the main advantages of using Sass mapping is the ability to directly access specific values, which makes the code more efficient and easier to read. However, nested lists may be faster to write and maintain

PHP Master | Generators in PHP

Core points The PHP generator provides an easy way to implement an iterator without the need for a complex Iterator interface, but instead uses the yield keyword instead of return to save its state and continues from the interrupt when called again. Generators are very memory-saving when working with large datasets, because they only need to allocate memory for the current result, without storing all values in memory at once like an array. Although the generator works like an iterator, it is essentially a function that returns and receives external values by calling the send() method of the generator object. It can also be used in another generator, which is called a generator delegate. If you have followed my previous article on iterators,

PHP Master | PhalconPHP: Yet Another PHP Framework?

Phalcon PHP framework: the perfect combination of speed and efficiency Core points: Phalcon stands out with its extremely high speed, thanks to its unique architecture: it is a PHP module written in C that runs at the system level, reducing overhead and memory footprint. The installation process of Phalcon is different from other frameworks. It is not simply downloading and decompressing, but installing as a PHP module. It is a full stack framework that includes functions such as ORM, request object library, and template engine. Benchmarks show Phalcon's request processing per second is more than twice that of CodeIgniter, highlighting its speed advantage. At the same time, it also has the classic features of modern PHP MVC framework

Using Sass's @error, @warn, and @debug Directives

Sass debugging tools: @error, @warn and @debug directives Sass provides three directives to help developers debug code: @error, @warn, and @debug. They are used to debug any value at any point in the code logic that needs help and find out the behavior of the code. @error directive: This directive will completely stop the Sass compiler and send the text string to the compiler's output as a fatal error. It is great for validating parameters in mixin or functions and letting developers know what they are doing wrong or entering completely incompatible values. @warn directive: This directive is less harmful than @error.
