Comparing Figma to Code Tools for Modern UI Developers

Fri, 15 May 2026 12:00:00 +0900

Explore the ecosystem of plugins translating Figma vector layouts into web assets and component classes.

Converting mockups from Figma into clean, responsive React, Vue, or HTML/CSS code has historically been a tedious, manual task. Today, modern “Figma-to-Code” tools use AI to interpret vector layouts and produce highly readable code. This article compares industry leaders—Anima, Locofy, and native Dev Mode plugins—and provides styling rules for your design files to guarantee clean code exports.

Advanced Tuning for Vite Build and Bundling Performance

Sun, 10 May 2026 12:00:00 +0900

Keep your Vite builds extremely fast using custom bundling settings and caching layers.

Vite is lightning-fast out of the box, but as codebases expand, production builds can slow down due to heavy Rollup compilation stages. This guide outlines how to optimize your builds using manualChunks, esbuild minification settings, and dependency pre-bundling configurations.

1. Code Splitting: Balancing Asset Sizes

By default, Vite bundles your application code into unified scripts. To prevent downloading unnecessary JavaScript during the initial page load, developers must implement robust code-splitting strategies.

PostgreSQL Performance Tuning for Web Developers

Mon, 20 Apr 2026 12:00:00 +0900

Optimize slow-performing applications by profiling database queries in PostgreSQL with EXPLAIN. Slow queries are the single largest bottleneck in most web applications. This guide walks you through essential index optimization guidelines, how to read execution plans, and key configuration parameter adjustments for self-hosted or managed databases.

1. Designing Effective Indexes

The primary bottleneck in modern databases is Disk I/O (reading block files from storage). Adding indexes allows PostgreSQL to query data records directly instead of scanning the entire table.

Accelerating GitHub Actions CI/CD workflows using Caching

Wed, 15 Apr 2026 12:00:00 +0900

Optimizing CI/CD workflow times directly impacts developer productivity and reduces computing expenses. This article shows you how to integrate dependency caching in GitHub Actions, helping you slash compilation and package setup times.

We provide YAML workflow templates for Node.js, Python, and Rust, alongside best practices to ensure optimal cache hits.

1. Why Cache Dependencies in CI/CD?

When a CI agent starts without caching, it spins up a clean container and fetches every dependency from package registries. This introduces several drawbacks:

Developing Browser Extensions with Manifest V3

Fri, 10 Apr 2026 12:00:00 +0900

Manifest V3 is now the official and mandatory specification for building Google Chrome extensions. With the deprecation of Manifest V2, developers must adopt non-persistent Service Workers for background processing and adapt to the declarative net request model. This guide explains the core architectural shifts in Manifest V3 and provides a simple walkthrough of setting up a compliant extension.

1. Primary Shifts from Manifest V2 to V3

Manifest V3 (MV3) was designed to make browser extensions more secure, privacy-respecting, and performant.

State of Rust Web Development: Top Framework Comparison

Sun, 05 Apr 2026 12:00:00 +0900

Rust has matured significantly as a premier backend language. This article evaluates the top Rust web frameworks, focusing on the differences between the current industry leaders: Axum and Actix-web. We cover their architectural patterns, performance profiles, and provide a bootstrap code snippet to help you choose the right framework.

1. Top Framework Overview

When building web applications or microservices in Rust, developers generally choose between these two frameworks:

1) Axum

Axum is developed and maintained by the tokio team, the creators of Rust’s de facto standard asynchronous runtime.

Docker Container Image Security Best Practices

Tue, 10 Mar 2026 12:00:00 +0900

In modern cloud-native development, Docker containers are the default standard for deploying web applications.

However, generic Dockerfiles often yield images containing OS vulnerabilities, unnecessary tooling, or root process privileges. In this guide, we cover the essential best practices to harden your Docker container images for production.

1. Enforce Multi-stage Builds

Leaving build tools, compiler caches, or developer dependencies (like npm or git) inside your final runtime image increases the container size and broadens the attack surface.

TypeScript 5 Features and Practical Best Practices

Thu, 05 Mar 2026 12:00:00 +0900

As the absolute standard for frontend and backend development, TypeScript continues to evolve.

The TypeScript 5.x releases focus heavily on compiler speed, bundle reductions, and syntax refinements that dramatically improve Developer Experience (DX). In this article, we cover practical TypeScript 5 features you should adopt in your daily workflows.

1. `const` Type Parameters

Previously, if you wanted TypeScript to infer an object literal arguments as narrow, read-only literal types, the caller had to append as const to the arguments.

Key Points for Performance Optimization in Next.js App Router

Wed, 25 Feb 2026 12:00:00 +0900

Leveraging React 18 capabilities, Next.js App Router provides a highly performant architecture for building modern web frontends.

However, misconfiguring server-client boundaries or caching rules can lead to slow response times. In this guide, we explore practical optimization techniques to build blazing-fast Next.js applications.

1. Maximize React Server Components (RSC)

The primary benefit of the App Router is that all components are Server Components by default. This eliminates large portions of JavaScript from the client-side bundle.
