A promise-based HTTP client for the browser and node.js. This documentation covers the Axios API, including request configuration, interceptors, instance creation, error handling, request cancellation using AbortController (v0.22.0+), and multipart/form-data requests, as well as source code analysis for version 1.5.0.

What's inside Axios

  1. Overview of Axios features

    Axios is an isomorphic, promise-based HTTP request library that works in both Node.js and browser environments. In Node.js, it uses the native http module, and in the browser, it uses XMLHttpRequests. Key features include:

    • Intercepting requests and responses
    • Transforming request and response data
    • Request cancellation and timeout handling
    • Automatic serialization of request bodies to JSON, Multipart/FormData, and URL encoded forms
    • Automatic JSON data transformation
    • Support for nested query parameter serialization
    • Request progress monitoring (speed, remaining time) for both Node.js and browsers
    • Bandwidth limiting for Node.js
    • Compatibility with FormData and Blob
    • Client-side XSRF protection

  2. Overview of Axios features

    Axios is a promise-based HTTP network request library compatible with both browser and Node.js environments. It is designed to be lightweight, easy to use, and provides extensible interfaces, allowing developers to share the same request logic between frontend and backend code.

  3. Overview of KubeKey installation tool

    KubeKey (developed in Go) is an installation tool used to deploy Kubernetes and KubeSphere. It replaces older Ansible-based installers to provide a more stable installation across diverse environments. Key use cases include:

    • Installing Kubernetes only
    • Installing both Kubernetes and KubeSphere with a single command
    • Scaling or upgrading clusters
    • Installing Kubernetes-related plugins via Chart or YAML

  4. Overview of Vue Router features

    Vue Router is the official router for Vue.js, designed to facilitate the creation of single-page applications (SPAs). Key features include:

    • Nested route mapping
    • Dynamic route matching
    • Modular, component-based configuration
    • Route parameters, queries, and wildcards
    • Integration with Vue.js transition system
    • Fine-grained navigation control
    • Automatic CSS class activation for links
    • Support for HTML5 history mode or hash mode
    • Customizable scrolling behavior
    • Proper URL encoding

  5. Docus documentation theme features overview

    Docus is a documentation framework built on Nuxt 3 that provides the following capabilities:

    • Content Authoring: Write pages in Markdown and use MDC (Markdown Components) syntax.
    • UI Components: Includes over 50 built-in components and leverages Typography and Elements for a configurable design system.
    • Layouts: Provides dedicated Docs and Page layouts with automatic Navigation and Table of Contents generation.
    • Integration: Fully compatible with Nuxt Studio for live-preview editing and the Nuxt 3 module ecosystem.
    • Deployment: Supports static generation, on-demand rendering (Node), or edge-side rendering (Cloudflare Workers) with zero-config deployment on Vercel and Netlify.
    • Extensibility: Allows full design customization and the addition of custom components via slots.

  6. Understand Axios Architecture Design

    Axios employs a modular architecture to ensure flexibility and extensibility. The codebase is organized into four primary sections:

    • Core: Manages the central request lifecycle, including dispatchRequest for sending requests and settle for handling responses.
    • Adapters: Encapsulates platform-specific low-level implementations, such as XMLHttpRequest for browsers and the http module for Node.js.
    • Helpers: Contains utility functions for URL manipulation, header processing, and request cancellation.
    • Defaults: Defines global default configurations, including default headers and timeout settings.

  7. How vue-router indexes routes for fast matching

    The matcher system uses two primary data structures to ensure efficient route resolution:

    1. matchers (Array): A list of RouteRecordMatcher objects sorted by score (priority). This allows the router to quickly find a matching route by iterating through the array in order of specificity.
    2. matcherMap (Map): A mapping where the key is the route name and the value is the corresponding RouteRecordMatcher. This enables O(1) lookup for named routes.

  8. Deploy clusters using KubeKey workflow

    KubeKey operates using the kk executable. The general workflow is:

    1. Prepare a configuration file: Define cluster parameters including host information, network configuration (CNI plugin, Pod and Service CIDR), repository mirrors, plugins (YAML/Chart), and KubeSphere components.
    2. Execute installation: Run the ./kk command with specific flags based on the desired operation (create, scale, or upgrade).
    3. Automatic Setup: KubeKey automatically installs Docker and pulls necessary images before proceeding with the installation.
    4. Verification: Review installation logs after the process completes.

  10. Install ELRepo to upgrade CentOS 7 kernel

    To upgrade the kernel on CentOS 7, you must first import the ELRepo GPG public key and install the ELRepo release package.
    # Import GPG key
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

# Install ELRepo for CentOS 7
yum install -y https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm

  11. Understand the Vue Router installation process

    When app.use(router) is called, the install method of the Router instance performs the following setup tasks:

    1. Global Components: Registers <RouterLink> and <RouterView> globally.
    2. Global Properties: Injects $router and $route into app.config.globalProperties for access in options API components.
    3. Dependency Injection: Uses app.provide to make the router instance and current route location available via inject in Composition API components.
    4. Initial Navigation: In browser environments, it triggers the initial navigation based on the current URL if it hasn't started yet.
    5. Lifecycle Management: Overrides app.unmount to clean up history listeners and reset the router state when the app is destroyed.

  12. Create a custom Vue 3 plugin

    A Vue plugin can be either an object with an install method or a standalone installation function. The installation function receives the application instance (app) and any optional arguments passed to app.use().
    const customPlugin = {
  install(app, options) {
    // Configure the app here
  }
}
