how I build this blog

thoughts

I will use tag more than headings, tag is better for searching and can avoid nested hierarchy, also it’s easier to create a tag than decide a heading.

I will log my digital life so I will be more trackable rather than opaque. Digital world is a water surface for users, I want to change this.

font-display

There are three fonts used in this blog, they almost took 20MB.

I need use font-display: swap; so the downloading of the font won’t block the text showing up.

@font-face {
  font-family: "Klee One Regular";
  src: url("/fonts/KleeOne-Regular.ttf") format("truetype");
  font-weight: 400;
  font-style: normal;
  font-display: swap;
}

make VSCode spell check work for mdx

Open an MDX file.
Ctrl + Shift + p Enable Spell Checking Document Language

https://github.com/streetsidesoftware/vscode-spell-checker/issues/657#issuecomment-755459018

If using vscode ssh, need to install Code Spell Checker extension in ssh again(there will be a button Install in SSH: 123.123.123.123 )

make image showing

If I have a mdx file in a folder, eg. archived/ielts.mdx , I need to use src="../images/name of the image" to make it showing.

variable

I have to use export to define a variable/constant.

export const photos = ["PXL_20240327_064431662.jpg"];

If I use const photos it will give me error.

nextra 和 vercel 结合生成 bug

tldr: 在 vercel 里设置 environment variable VERCEL_FORCE_NO_BUILD_CACHE = 1

我也不知怎么回事，也许 nextra 的 static site generation 和 vercel cache 产生奇妙反应，侧边栏就会出现类似 stale state 的现象。

我试试这篇文章推上去，让 vercel 自动 deploy 看看会不会有问题。

据说要把 remote caching 关了

再试一次，原神启动！

原神再启动！

原神启不动！

我的初心是写博客，不是搞技术，更不是写技术博客。

还是要设置环境变量来跳过 build cache

EDIT (14th Oct 2022): The VERCEL_FORCE_NO_BUILD_CACHE env var now exists! Set this to 1 and the build cache will be skipped.

终于，原神亲自启动了。

install tailwind CSS

_app.tsx

import type { AppProps } from "next/app";
import "../globals.css"; // this must be put here
 
export default function App({ Component, pageProps }: AppProps) {
  return <Component {...pageProps} />;
}

Install Tailwind CSS with Next.js

这些没有文档记录的东西，不知哪天就会 Move fast , break things!

add RSS support

I found that there are a rss generator of nextra blog theme, I’m gonna give it a try.

create script/gen-rss.js , fill it with gen-rss.js

modify package.json

add the rss generation to build command

    "build": "node ./scripts/gen-rss.js && next build",

add new dependencies

    "gray-matter": "^4.0.3",
    "rss": "^1.2.2"

~~install dependencies and run build~~ of course it won’t work, I’m using the nextra doc theme, it doesn’t have frontmatter

finally I managed to publish the feed.xml , but there isn’t any title & content! But it can give the notification anyway. Move fast!

to do

environment variable

https://nextjs.org/docs/app/building-your-application/configuring/environment-variables#loading-environment-variables

create .env.local and use it like process.env.SOME_ENV

For safari, video tag should have playsinline , otherwise it will jump out to fullscreen. If using JSX, maybe should use webkit-playsinline={true}

<div className="flex flex-col items-center justify-center">
  <video
    className="w-full h-auto md:w-80"
    autoPlay
    muted
    loop
    playsinline
    webkit-playsinline={true}
  >
    <source src="videos/ezgif-7-53636bcd6f.mp4" type="video/mp4" />
    Your browser does not support the video tag.
  </video>
  <Caption children={"《天下无贼》中找到了生活的其他部分的劫匪"} />
</div>

Friend with iPhone 12 says that it’s still not working. The video still jump out. Okay, I’ll go back to gif. Feck it.

看了看 svelte4 ，据说又要 svelte5 ，语法大改动。也许用无聊的技术是对的，你还在各种技术栈反复横跳， jquery 都 4 beta 了 , PHP 都兰博基尼了。
