|
||||
|
||||
## 🚀 第1步:JS按需加载优化
|
||||
|
||||
### 1.1 优化目标
|
||||
|
||||
将JS拆分为多个bundle,实现按需加载:
|
||||
- 核心JS始终加载
|
||||
- 页面特定JS按需加载
|
||||
- 非关键JS延迟加载
|
||||
|
||||
### 1.2 实施步骤
|
||||
|
||||
#### 步骤1:分析JS结构
|
||||
|
||||
**核心JS(必须加载):**
|
||||
- UIkit框架
|
||||
- 图标字体
|
||||
- 图片灯箱
|
||||
- 工具函数
|
||||
- 搜索功能
|
||||
- 浮动工具
|
||||
- 进度条
|
||||
- PJAX
|
||||
- 主题主逻辑
|
||||
|
||||
**页面特定JS(按需加载):**
|
||||
- Artalk评论系统(文章详情页)
|
||||
- 段落评论(文章详情页)
|
||||
- 打赏功能(文章详情页)
|
||||
|
||||
**延迟加载的JS:**
|
||||
- Toast消息
|
||||
- 图片懒加载
|
||||
|
||||
---
|
||||
|
||||
#### 步骤2:修改footer.html
|
||||
|
||||
**文件:** `themes/Ying/layouts/partials/footer.html`
|
||||
|
||||
**修改内容:**
|
||||
|
||||
1. 创建核心JS bundle
|
||||
```gohtml
|
||||
{{ $coreScripts := slice $iconfont $uikit $viewimage $utils $loader $cache $search $floatingTools $nprogress $pjaxLib $mypjax $pangu $linkify $main | resources.Concat "js/core.js" | resources.Minify | resources.Fingerprint }}
|
||||
|
||||
<script defer src="{{ $coreScripts.RelPermalink }}"></script>
|
||||
```
|
||||
|
||||
2. 创建页面特定JS bundle
|
||||
```gohtml
|
||||
{{ if .IsPage }}
|
||||
{{ $artalkModule := resources.Get "js/modules/artalk.js" }}
|
||||
{{ $paragraphComments := resources.Get "js/modules/paragraph-comments.js" }}
|
||||
{{ $reward := resources.Get "js/modules/reward.js" }}
|
||||
|
||||
{{ $pageScripts := slice $artalkModule $paragraphComments $reward | resources.Concat "js/page-only.js" | resources.Minify | resources.Fingerprint }}
|
||||
|
||||
<script defer src="{{ $pageScripts.RelPermalink }}"></script>
|
||||
<script>window._pageOnlyScriptUrl = '{{ $pageScripts.RelPermalink }}';</script>
|
||||
{{ end }}
|
||||
```
|
||||
|
||||
3. 创建延迟加载JS bundle
|
||||
```gohtml
|
||||
{{ $toast := resources.Get "js/modules/toast.js" }}
|
||||
{{ $easylazyload := resources.Get "js/modules/lazyload.js" }}
|
||||
|
||||
{{ $deferredScripts := slice $toast $easylazyload | resources.Concat "js/deferred.js" | resources.Minify | resources.Fingerprint }}
|
||||
|
||||
<script>
|
||||
if ('requestIdleCallback' in window) {
|
||||
requestIdleCallback(function() {
|
||||
var script = document.createElement('script');
|
||||
script.src = '{{ $deferredScripts.RelPermalink }}';
|
||||
script.defer = true;
|
||||
document.body.appendChild(script);
|
||||
});
|
||||
} else {
|
||||
setTimeout(function() {
|
||||
var script = document.createElement('script');
|
||||
script.src = '{{ $deferredScripts.RelPermalink }}';
|
||||
script.defer = true;
|
||||
document.body.appendChild(script);
|
||||
}, 1000);
|
||||
}
|
||||
</script>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤3:适配PJAX
|
||||
|
||||
**文件:** `themes/Ying/assets/js/modules/mypjax.js`
|
||||
|
||||
**修改内容:**
|
||||
|
||||
在 `pjax:complete` 事件中添加动态加载逻辑:
|
||||
|
||||
```javascript
|
||||
// 动态加载页面特定JS(PJAX适配)
|
||||
var isArticlePage = document.querySelector('#Comments') !== null ||
|
||||
document.querySelector('.post-content') !== null;
|
||||
|
||||
if (isArticlePage && !window._pageOnlyLoaded && window._pageOnlyScriptUrl) {
|
||||
var script = document.createElement('script');
|
||||
script.src = window._pageOnlyScriptUrl;
|
||||
script.onload = function() {
|
||||
window._pageOnlyLoaded = true;
|
||||
console.log('page-only.js loaded for PJAX navigation');
|
||||
if (typeof window.initArtalk === 'function') {
|
||||
try { window.initArtalk(); } catch(e) {}
|
||||
}
|
||||
};
|
||||
document.body.appendChild(script);
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## 🚀 第2步:字体子集化优化
|
||||
|
||||
### 2.1 优化目标
|
||||
|
||||
将中文字体从1.2MB优化到757KB,减少37%。
|
||||
|
||||
### 2.2 实施步骤
|
||||
|
||||
#### 步骤1:备份原始字体
|
||||
|
||||
```bash
|
||||
cd E:\GitHub\blog
|
||||
|
||||
# Windows
|
||||
copy themes\Ying\static\font\zql-v2.woff2 themes\Ying\static\font\zql-v2.woff2.backup
|
||||
copy themes\Ying\static\font\zql-v2.woff themes\Ying\static\font\zql-v2.woff.backup
|
||||
|
||||
# Mac/Linux
|
||||
cp themes/Ying/static/font/zql-v2.woff2 themes/Ying/static/font/zql-v2.woff2.backup
|
||||
cp themes/Ying/static/font/zql-v2.woff themes/Ying/static/font/zql-v2.woff.backup
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤2:安装Python依赖
|
||||
|
||||
```bash
|
||||
pip install fonttools brotli
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤3:构建Hugo站点
|
||||
|
||||
```bash
|
||||
hugo --destination=public
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤4:运行字体子集化
|
||||
|
||||
```bash
|
||||
python scripts/subset-font-safe.py
|
||||
```
|
||||
|
||||
**预期输出:**
|
||||
```
|
||||
🔤 字体子集化工具(安全版本)
|
||||
==================================================
|
||||
✅ 找到public目录,将扫描构建后的HTML
|
||||
🔍 扫描目录: content, layouts, public
|
||||
📝 提取了 2492 个唯一字符
|
||||
💾 字符列表已保存到: themes/Ying/static/font\used_chars.txt
|
||||
✂️ 正在生成子集字体...
|
||||
✅ 子集化完成!
|
||||
📊 优化结果:
|
||||
子集字符数: 2485
|
||||
子集文件大小: 739.7 KB
|
||||
减少: 486.8 KB (39.7%)
|
||||
🎉 所有子集字体生成成功!
|
||||
```
|
||||
|
||||

|
||||
|
||||
#### 步骤5:更新CSS字体声明
|
||||
|
||||
**文件:** `themes/Ying/assets/css/main.css`
|
||||
|
||||
**修改字体声明:**
|
||||
|
||||
```css
|
||||
@font-face {
|
||||
font-family: 'zql';
|
||||
src: url('../font/zql-v2-subset.woff2') format('woff2'),
|
||||
url('../font/zql-v2-subset.woff') format('woff');
|
||||
font-display: swap;
|
||||
}
|
||||
```
|
||||
|
||||
**关键改动:**
|
||||
- `zql-v2.woff2` → `zql-v2-subset.woff2`
|
||||
- `zql-v2.woff` → `zql-v2-subset.woff`
|
||||
- 删除 `unicode-range`
|

|
||||
|
||||
## 🚀 第3步:GitHub Actions自动化
|
||||
|
||||
### 3.1 优化目标
|
||||
|
||||
实现字体子集化的完全自动化:
|
||||
- 内容更新时自动优化
|
||||
- 每周定期检查
|
||||
- 智能检测变更
|
||||
- 与deploy.yml完美协调
|
||||
|
||||
### 3.2 实施步骤
|
||||
|
||||
#### 步骤1:创建requirements.txt
|
||||
|
||||
**文件:** `requirements.txt`
|
||||
|
||||
```
|
||||
fonttools
|
||||
brotli
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤2:创建GitHub Actions工作流
|
||||
|
||||
**文件:** `.github/workflows/subset-fonts.yml`
|
||||
|
||||
**关键配置:**
|
||||
|
||||
1. **触发条件:**
|
||||
```yaml
|
||||
on:
|
||||
push:
|
||||
branches:
|
||||
- main
|
||||
paths:
|
||||
- 'content/**'
|
||||
- 'layouts/**'
|
||||
schedule:
|
||||
- cron: '0 2 * * 1' # 每周一凌晨2点
|
||||
workflow_dispatch:
|
||||
inputs:
|
||||
force_rebuild:
|
||||
description: '强制重新生成子集字体'
|
||||
required: false
|
||||
default: 'false'
|
||||
type: boolean
|
||||
```
|
||||
|
||||
2. **工作流步骤:**
|
||||
```yaml
|
||||
steps:
|
||||
- name: Checkout repository
|
||||
uses: actions/checkout@v4
|
||||
|
||||
- name: Set up Python
|
||||
uses: actions/setup-python@v5
|
||||
with:
|
||||
python-version: '3.11'
|
||||
cache: 'pip'
|
||||
|
||||
- name: Install dependencies
|
||||
run: |
|
||||
pip install fonttools brotli
|
||||
|
||||
- name: Build Hugo site
|
||||
uses: peaceiris/actions-hugo@v2
|
||||
with:
|
||||
hugo-version: 'latest'
|
||||
extended: true
|
||||
|
||||
- name: Subset fonts
|
||||
run: python scripts/subset-font-safe.py
|
||||
|
||||
- name: Commit changes
|
||||
run: |
|
||||
git config --local user.email "github-actions[bot]@users.noreply.github.com"
|
||||
git config --local user.name "github-actions[bot]"
|
||||
git add themes/Ying/static/font/zql-v2-subset.*
|
||||
git commit -m "chore: update font subset (automated) [skip ci]"
|
||||
|
||||
- name: Push changes
|
||||
run: git push origin main
|
||||
```
|
||||
|
||||
3. **避免循环触发:**
|
||||
```yaml
|
||||
git commit -m "chore: update font subset (automated) [skip ci]"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 步骤3:与deploy.yml协调
|
||||
|
||||
**你的deploy.yml已有防循环机制:**
|
||||
|
||||
```yaml
|
||||
- name: Push Image Optimizations
|
||||
run: |
|
||||
if ! git log --oneline -1 | grep -q "\[skip ci\]"; then
|
||||
echo "No auto-commits to push"
|
||||
else
|
||||
git push origin HEAD:main
|
||||
fi
|
||||
```
|
||||
|
||||
**协调流程:**
|
||||
```
|
||||
你push到main
|
||||
↓
|
||||
deploy.yml(部署文章)
|
||||
↓
|
||||
subset-fonts.yml(优化字体)
|
||||
↓
|
||||
commit [skip ci]
|
||||
↓
|
||||
push到main
|
||||
↓
|
||||
deploy.yml看到[skip ci],不再次触发 ✅
|
||||
↓
|
||||
完美协调!
|
||||
```
|
||||
