This article explains the concept of Cross‑Origin Resource Sharing (CORS), demonstrates how to identify cross‑origin requests, and provides a complete Spring Boot backend configuration together with Vue3/Axios frontend code to solve CORS issues in a full‑stack web application.
This article explains the fundamentals of token‑based authentication, the drawbacks of fixed token lifetimes, and presents multiple silent‑refresh techniques—including double‑token mechanisms, front‑end timers, server‑side proactive refresh, and concurrency‑safe lock strategies—along with practical code examples and performance considerations for high‑concurrency scenarios.
This article explains why and how to wrap asynchronous API calls in a reusable TypeScript utility using Axios, covering request flow analysis, interceptor design, unified GET/POST/PUT/DELETE helpers, development order, and complete source code examples for a maintainable frontend architecture.
This tutorial walks through setting up a Vue2 front‑end environment, installing Node.js, Vue‑CLI, Element UI, and Axios, then creates a reusable hot‑search board component, integrates it into the main app, and even shows a Java‑based Zhihu crawler for data collection.
This article explains the two ways to call Axios—using a configuration object or shortcut methods—then walks through building a minimal Axios clone, detailing its constructor, prototype methods, and the clever instance creation that lets the library behave both as a function and an object.
This article explains how to implement seamless, invisible token refresh for authentication systems, covering client‑side strategies using Axios interceptors and timers, server‑side gateway filters with Spring Boot, code examples for detecting token expiration, obtaining new tokens, and choosing between client and server approaches based on security and performance considerations.
This article explains how to implement invisible token refresh for authentication systems, covering server‑side gateway filtering in Spring Boot, client‑side Axios interceptors, timer‑based proactive checks, and practical code examples to address token expiration, parsing, and renewal challenges.
This tutorial demonstrates how to create a NestJS backend that converts Chinese city names to pinyin, retrieves the corresponding city ID from the QWeather API, and returns a 7‑day weather forecast using a unified Axios HTTP client configuration.
This article explains how to prevent multiple simultaneous token requests in a web application by using a custom repeatOnce function that caches the token in localStorage and coordinates pending calls through an event emitter, ensuring only the first request fetches the token while others wait for its result.
This article explains how to achieve seamless token silent refresh by handling expiration on the server side with a Spring Boot 3 gateway filter, on the client side with an Axios response interceptor, and by using a TypeScript timer to proactively refresh tokens before they expire, while also discussing the trade‑offs between server‑ and client‑side implementations.
The article presents a full‑stack solution for seamless token auto‑refresh, combining a Spring Cloud Gateway GlobalFilter that signals expiration with a custom 511 status, Axios response interceptors and a TypeScript timer on the client, plus server‑side token metadata, allowing developers to choose server‑centric or client‑centric refresh strategies.
The article explains why repeated button clicks or searches cause duplicate API calls, discusses why debounce/throttle are not ideal, and presents three practical solutions—loading state locking, request cancellation with Axios CancelToken, and related code examples—to efficiently avoid redundant requests in Vue applications.
This guide walks through setting up a Vue3 project with Vite4, Pinia, and Axios—including version specifications, directory structure, installation commands, Pinia persistence, Axios configuration, auto‑import setup, and Uni‑UI integration—providing complete code snippets for each step.
This tutorial demonstrates how to use Spring WebFlux’s reactive streaming to create a ChatGPT‑like typing effect, covering backend setup, SSE integration, frontend Axios handling, and a comparison between Flux and traditional Server‑Sent Events.
This article explains how to handle sudden login redirects caused by expired JWT access tokens in a web platform by using Axios response interceptors to automatically refresh tokens, queue failed requests, and retry them without disrupting the user experience.
The article presents @varlet/axle, a progressive request utility that fully inherits Axios capabilities while adding unified request parameters, extensive configuration, built‑in interceptors, Vue composition‑API integration, and parallel request tools, offering developers a convenient library for handling HTTP calls.
The article presents a comprehensive strategy for handling API outages by storing data locally with IndexedDB, synchronizing updates through a CDN, and implementing Axios interceptors and Node‑based scheduled jobs to ensure seamless user experience without white‑screen failures.
Axios is a popular HTTP client for JavaScript that simplifies making HTTP requests, supports promise-based APIs, and offers features like request/response interceptors and automatic JSON data transformation.
This step‑by‑step guide shows backend developers how to create a small management system with Vue 3, TypeScript, Vite, and SpringBoot, covering the technology stack, development‑tool installation, project scaffolding, core components, routing, Pinia state, Axios API wrappers, TypeScript interfaces, environment configuration, and deployment.
This article demonstrates how to create a reusable Axios wrapper for Vue3 projects, covering basic class‑based encapsulation, flexible global and instance interceptors, custom request configuration types, request cancellation management, and practical testing examples, all written in TypeScript.
