构建一个简约博皮的过程
前置
由于之前构建的皮肤 reacg 偏二次元风,尽管提供了大量配置(包括几乎任何颜色、插件等的配置),依然有人吐槽花里胡哨,遂重新构建了一款简约风格的博客园皮肤, 正如你所见。下文我将从零介绍它的构建过程,构建它最快花费一个小时到几个小时。由于之前做了大量工作,所以现在按照流程走一遍就完事了。
准备工作
- 环境:node & npm
- git clone https://gitee.com/guangzan/awescnb.git
- 运行
npm install
安装依赖 - 在 themes 文件夹下新建 simple 文件夹、simple/index.js
配置
config/options.js,这是 webpack 的配置:
module.exports = {
themeName: 'simple',
template: 'index',
eslint: true,
sourceMap: false,
openAnalyzer: true,
cssExtract: false,
openBrowser: false,
// ...
}
看个人所需,我在这里简单配置如下:
- themeName: 'simple' 对应 themes/simple 文件夹
- template: 运行 npm start 打开博客园首页模板
- 开启 eslint
- 开启 Analyzer,运行 npm run build 时我需要检查最终构建的体积大小
- cssExtract 先不分离 css,构建完成直接推送到远端,直接切换线上版本
开始
- simple/style 下存放样式文件
- index.scss
- index.m.scss
- markdown.scss
- reset.scss
- tools.scss
最终只在入口文件 index.js 中导入 index.scss,其他 scss 由 index.scss 引入,由于之前编好了样式代码,所以需要新编写的样式极少。
- simple/plugins/index.js
引入构建好的博客园插件,不需要写任何功能代码,及其样式。
import footer from '@plugins/footer'
import highlight from '@plugins/highlight'
import copy from '@plugins/copy'
import linenumbers from '@plugins/linenumbers'
import imagebox from '@plugins/imagebox'
import commentsAvatars from '@plugins/commentsAvatars'
import dragMenu from '@plugins/dragMenu'
import donation from '@plugins/donation'
import emoji from '@plugins/emoji'
import player from '@plugins/player'
import postMessage from '@plugins/postMessage'
import postSignature from '@plugins/postSignature'
import postTopimage from '@plugins/postTopimage'
import notice from '@plugins/notice'
const plugins = () => {
footer()
highlight()
copy()
linenumbers()
imagebox()
commentsAvatars()
donation()
dragMenu()
emoji()
player()
postMessage()
postSignature()
postTopimage()
notice()
}
module.exports = plugins
- 构建 footer 链接
- mac 样式代码高亮
- 代码行号
- 图片灯箱
- 显示评论区头像
- 捐增二维码
- 按钮工具条(返回顶部,推荐,收藏。。。)
- 评论框表情
- 播放器
- 在文章头部构建文章信息
- 构建文章签名信息
- 文章头图
- 通知功能
由于这个皮肤的基调是简约,所以只引入一些常用的功能模块。花里胡哨的就不考虑了。
- simple/build/index.js
index.js 引入了一些其他 JavaScript 用来做一些调整,例如 simple/build 文件夹下我还写了
- catalog(文章目录)
- header(头部导航逻辑)
- scroll(滚动控制)
- side (侧边栏逻辑)
catalog/index.js
代码有些长,我将它折叠

pageName,
userAgent,
hasPostTitle,
getClientRect,
throttle,

</div>`,
)

const titleRegExp = /^h[1-3]$/
$('#cnblogs_post_body')
.children()
.each(function() {
if (titleRegExp.test(this.tagName.toLowerCase())) {
if ($(this).text().length === 0) return // 如果标题为空 只有 #
let id
let text
if (this.id !== '') {
id = this.id
text =
this.childNodes.length === 2
? this.childNodes[1].nodeValue
: this.childNodes[0].nodeValue
} else {
if (this.childNodes.length === 2) {
const value = this.childNodes[1].nodeValue
text = value ? value : $(this.childNodes[1]).text()
} else {
const value = this.childNodes[0].nodeValue
text = value ? value : $(this.childNodes[0]).text() // 处理标题被 span 包裹的情况
}
id = text.trim()
$(this).attr('id', id)
}
const title = `
<li class='${this.nodeName.toLowerCase()}-list'>
<a href='#${id}'>${text}</a>
</li>
`
$ulContainer.append(title)
}
})
const $catalog = $($catalogContainer.append($ulContainer))
$('#sidebar_news').after($catalog)

- simple/index.js
唯一需要写的样板代码:
import './style/index.scss'
import AwesCnb from '@awescnb'
class Simple extends AwesCnb {
constructor() {
super()
super.init(this.init)
}
init() {
require('./build')()
require('./plugins')()
}
}
new Simple()
构建
- 运行
npm start
分别对首页、随笔详情页、标签页等调整 - 运行
npm run build
打包
皮肤 simple 所有样式和逻辑加起来有 130+kb,没有异常。如果想拥有更好的体验可以将 css 分离,在文章开头的配置介绍中提供了这个选项。最后推送上去就能在博客园切换到新皮肤了。
