When encountering a problem, the first response should be thinking and analyzing. Cultivating this thinking habit in the brain is essential, rather than getting stuck in a "dead end of confusion" and staring blankly. I describe this state of stagnation and lack of thinking ability with phrases like: "Why is this happening!?", "It shouldn't be like this?!", "Theoretically, it's impossible?!", "Why on earth is this happening!?", or immediately asking others. Problems need to be solved through independent thinking to gain the most insight and depth.

Initialization Phase#
navigationStart: The creation time of the current page or the unload time of the previous page
unloadEventStart: The time when the unload event callback of the previous page starts executing
unloadEventEnd: The time when the unload event callback of the previous page finishes executing
redirectStart: The start time of the redirect
redirectEnd: The end time of the redirect
Connection Phase#
fetchStart: The time when the fetch sends a GET request
domainLookupStart: The start time of DNS resolution
domainLookupEnd: The end time of DNS resolution

secureConnectionStart: For HTTPS, the time when SSL starts connecting; otherwise, it is 0
connectEnd: The time when TCP connection is completed
Request Phase#
requestStart: The time when the request is sent
responseStart: The time when the response starts being received from the server (or cache, local resources)
responseEnd: The end time of the response
Rendering Phase#
domLoading: The time when the document starts loading, at this point document.readyState = 'loading'
domInteractive: The DOM is built, but sub-resources such as images, js, css, iframes, etc., are still loading; at this point, document.readyState = 'interactive', triggering the DOMContentLoaded event
domContentLoadedEventStart: The time when the DOMContentLoaded event callback starts executing
domContentLoadedEventEnd: The time when the DOMContentLoaded event callback finishes executing
domComplete: The time when the document and its sub-resources are fully loaded, at this point document.readyState = 'complete', triggering the load event

A Plugin for Optimizing SVG in Projects#
svg-chunk-webpack-plugin is a community-contributed webpack plugin that provides "code splitting" for SVG with zero configuration, optimizing SVG references in projects; it can also reduce the size of SVG code provided by designers. The author provides an example, assuming there are three components that import some SVG files:
// news.js
import '../svgs/smiley-surprised.svg';
import '../svgs/popcorn.svg';
// components.js
import '../svgs/smiley-love.svg';
// home.js
import './component.js';
import '../svgs/gradient.svg';
import '../svgs/video.svg';
Webpack build file input and output configuration:
entry: {
home: `${path.resolve(__dirname, './src/js/home.js')}`,
news: `${path.resolve(__dirname, './src/js/news.js')}`
},
output: {
path: path.resolve(__dirname, './dist'),
publicPath: '/dist/',
filename: 'js/[name].js'
},
Finally, SVG files will be output separately based on the entry files:

A Free and Useful Browser Screen Recording Plugin#
screenity is an incredibly useful free plugin. It has a friendly interface, is easy to operate, and has powerful features. Click to start recording, click again to stop recording, and it supports free cropping and downloading in multiple formats (gif, mp4, webm). It improves efficiency in scenarios where remote reproduction of issues during development and quick screen sharing are needed.
How to Efficiently Switch Proxies#
lightproxy is an open-source proxy tool from Alibaba that is much easier to use than Proxyman/Charles. The rule configuration is consistent with the host file syntax, supports domain name wildcards, and file-level granularity, allowing easy opening, closing, switching, and proxying mobile requests. Here are a few configurations I commonly use:
switchyomega is a browser plugin that integrates proxy management/switching and request forwarding, making it convenient to quickly switch between different proxies or forward requests to different proxies.
It supports different scenario modes, such as:
- Proxy server: For example, if I use a VPN software called Little Cat, also known as Clash for Windows, I can configure a proxy server through SwitchyOmega, setting the port number to the running port of Little Cat.
- Automatic switching mode: Automatically switch to a specified proxy server based on various conditions. For example, I can use domain wildcards to forward traffic to foreign websites to Little Cat, while directly connecting traffic to domestic websites, thus achieving a better surfing experience.
- Direct connection: This means not using any proxy, and network requests are directly connected.
- System proxy: Proxy configuration for other extensions or operating system environments.

Independent Developer Navigation Site#
Indie hackers is a navigation site for independent developers, categorizing tools used by independent developers to help newcomers speed up application delivery. It's great; I really need it at this stage as I am just starting out.
Google SEO#
Just like web.dev provides a specialized learning resource for optimizing frontend application performance with Core Web Vitals, google search center offers knowledge related to website SEO optimization for learning in the SEO optimization field.
AITDK#
aitdk uses AI to assist with SEO, allowing you to input descriptions and generate TDK. There are many factors that influence SEO ranking, and I believe that after becoming very familiar with these factors, using AI capabilities to optimize them one by one is a promising platform.
Screen Studio#
screen.studio is amazing; just go to the official website to see the introduction. It is an all-in-one screen recording client software used by major companies like Microsoft, Google, Vercel, and Adobe; it's incredibly versatile.
