前置

因爲以前構建的皮膚 reacg 偏二次元風，儘管提供了大量配置(包括幾乎任何顏色、插件等的配置)，依然有人吐槽花裏胡哨，遂從新構建了一款簡約風格的博客園皮膚, 正如你所見。下文我將從零介紹它的構建過程，構建它最快花費一個小時到幾個小時。因爲以前作了大量工做，因此如今按照流程走一遍就完事了。css

準備工做

環境：node & npm
git clone https://gitee.com/guangzan/awescnb.git
運行 npm install 安裝依賴
在 themes 文件夾下新建 simple 文件夾、simple/index.js

配置

config/options.js，這是 webpack 的配置：node

module.exports = {
    themeName: 'simple',
    template: 'index',
    eslint: true,
    sourceMap: false,
    openAnalyzer: true,
    cssExtract: false,
    openBrowser: false,
    // ...
}

看我的所需，我在這裏簡單配置以下：webpack

themeName: 'simple' 對應 themes/simple 文件夾
template: 運行 npm start 打開博客園首頁模板
開啓 eslint
開啓 Analyzer，運行 npm run build 時我須要檢查最終構建的體積大小
cssExtract 先不分離 css，構建完成直接推送到遠端，直接切換線上版本

開始

simple/style 下存放樣式文件

index.scss
index.m.scss
markdown.scss
reset.scss
tools.scss

最終只在入口文件 index.js 中導入 index.scss，其餘 scss 由 index.scss 引入，因爲以前編好了樣式代碼，因此須要新編寫的樣式極少。git

simple/plugins/index.js

引入構建好的博客園插件，不須要寫任何功能代碼，及其樣式。github

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

構建 footer 連接
mac 樣式代碼高亮
代碼行號
圖片燈箱
顯示評論區頭像
捐增二維碼
按鈕工具條（返回頂部，推薦，收藏。。。）
評論框表情
播放器
在文章頭部構建文章信息
構建文章簽名信息
文章頭圖
通知功能

因爲這個皮膚的基調是簡約，因此只引入一些經常使用的功能模塊。花裏胡哨的就不考慮了。web

simple/build/index.js

index.js 引入了一些其餘 JavaScript 用來作一些調整，例如 simple/build 文件夾下我還寫了npm

catalog（文章目錄）
header（頭部導航邏輯）
scroll（滾動控制）
side (側邊欄邏輯)

catalog/index.jsmarkdown

代碼有些長，我將它摺疊

import './index.scss'

    pageName,
    userAgent,
    hasPostTitle,
    getClientRect,
    throttle,

    )
    const $ulContainer = $('<ul></ul>')
    const titleRegExp = /^h[1-3]$/

    $('#cnblogs_post_body')
        .children()
        .each(function() {
            if (titleRegExp.test(this.tagName.toLowerCase())) {
                if ($(this).text().length === 0) return // 若是標題爲空 只有 #
                let id
                let text

                if (this.id !== '') {
                    id = this.id
                    text =

                            : this.childNodes[0].nodeValue
                } else {
                    if (this.childNodes.length === 2) {
                        const value = this.childNodes[1].nodeValue
                        text = value ? value : $(this.childNodes[1]).text()
                    } else {

                        text = value ? value : $(this.childNodes[0]).text() // 處理標題被 span 包裹的狀況
                    }
                    id = text.trim()
                    $(this).attr('id', id)
                }

                const title = `
