Usage

简化了,就三个命令:

# create a new slide with an official template
$ nodeppt new slide.md

# create a new slide straight from a github template
$ nodeppt new slide.md -t username/repo

# start local sever show slide
$ nodeppt serve slide.md

# to build a slide
$ nodeppt build slide.md

帮助

# help
nodeppt -h
# 获取帮助
nodeppt serve -h

演讲者模式

nodeppt 有演讲者模式,在页面 url 后面增加?mode=speaker 既可以打开演讲者模式,双屏同步

Keyboard Shortcuts

公共资源:public 文件夹

如果项目文件夹下,存在public文件夹,可以直接通过 url 访问,参考webpack dev server的 contentBase 选项。

在build的时候,public 文件夹中的文件会完全 copy 到dist文件夹中

编写

最佳体验是 chrome 浏览器,本来就是给做演示用的,所以就别考虑非 Chrome 浏览器兼容问题了!

这里说下怎么编写。

基本语法

整个 markdown 文件分为两部分,第一部分是写在最前面的配置,然后是使用<slide>隔开的每页幻灯片内容。

配置

nodeppt 的配置是直接写在 md 文件顶部的,采用 yaml 语法,例如下面配置:

title: nodeppt markdown 演示
speaker: 三水清
url: https://github.com/ksky521/nodeppt
js:
    - https://www.echartsjs.com/asset/theme/shine.js
prismTheme: solarizedlight
plugins:
    - echarts
    - mermaid
    - katex

插件

目前 nodeppt 支持 图表 echarts,流程图 mermaid,数学符号 KaTeX 三个插件。

echarts

echarts 主题配色可以直接在yaml配置的 js 中引入。echarts 采用fence语法,如下:

{
    xAxis: {
        type: 'category',
        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
    },
    yAxis: {
        type: 'value'
    },
    series: [{
        data: [820, 932, 901, 934, 1290, 1330, 1320],
        type: 'line'
    }]
}

详见site/echarts.md

mermaid

mermaid 主题配色可以直接在yaml配置的 js 中引入。mermaid 采用fence语法,如下:

sequenceDiagram
    Alice ->> Bob: Hello Bob, how are you?
    Bob-->>John: How about you John?
    Bob--x Alice: I am good thanks!
    Bob-x John: I am good thanks!
    Note right of John: Bob thinks a long<br/>long time, so long<br/>that the text does<br/>not fit on a row.

    Bob-->Alice: Checking with John...
    Alice->John: Yes... John, how are you?

详见site/mermaid.md

ketex

参考:markdown-it-katex语法

<slide> 语法

nodeppt 会根据<slide>对整个 markdown 文件进行拆分,拆成单页的幻灯片内容。<slide> 标签支持下面标签:

每个 slide 会解析成下面的 html 结构:

<section class="slide" attrs...><div class="wrap" wrap="true">// 具体 markdown 渲染的内容</div></section>

其中<slide> 的class等会被解析到 <section>标签上面,而:class则被解析到div.wrap上面,例如:

<slide :class="size-50" class="bg-primary"></slide>

output 为:

<section class="slide bg-primary"><div class="wrap size-50" wrap="true">// 具体 markdown 渲染的内容</div></section>

背景:图片

<slide>的image 会被解析成背景大图,常见的支持方式有:

<slide image="https://source.unsplash.com/UJbHNoVPZW0/">

# 这是一个普通的背景图

<slide image="https://source.unsplash.com/UJbHNoVPZW0/ .dark">

# 这张背景图会在图片上面蒙一层偏黑色的透明层

<slide image="https://source.unsplash.com/UJbHNoVPZW0/ .light">

# 这张背景图会在图片上面蒙一层偏白色的透明层

<slide class="bg-black aligncenter" image="https://source.unsplash.com/n9WPPWiPPJw/ .anim">

# 这张背景图会缓慢动

详见site/background.md和在线演示

样式

样式太多,具体详见site/classes.md和在线演示

布局

nodeppt 这次使用webslides的布局,支持丰富的布局,实在太多了,直接看文档site/layout.md和在线演示

attribute

参考markdown-it-attrs,支持了attribute,修改增加多 class 支持等功能。

其中:..class会往上一级节点添加 class,支持{.class1.class2}这种多 class 的语法。用法举例:

# header {.style-me.class2}

paragraph {data-toggle=modal}

Output:

<h1 class="style-me class2">header</h1>
<p data-toggle="modal">paragraph</p>
Use the css-module green on this paragraph. {.text-intro}

Output:

<p class="text-intro">Use the css-module green on this paragraph.</p>
-   list item **bold** {.red}

Output:

<ul>
    <li class="red">list item <strong>bold</strong></li>
</ul>
-   list item **bold**
    {.red}

Output:

<ul class="red">
    <li>list item <strong>bold</strong></li>
</ul>

image 增强

对于 image ,支持外面包裹一层的写法,具体语法 !![](图片地址 属性),例如:

!![](https://webslides.tv/static/images/iphone.png .size-50.alignleft)

Output:

<img src="https://webslides.tv/static/images/iphone.png" class="size-50 alignleft" />
!![figure](https://webslides.tv/static/images/setup.png .aligncenter)

Output:

<figure><img src="https://webslides.tv/static/images/setup.png" class="aligncenter" /></figure>

button

nodeppt 的 button 是类似link语法的,支持蓝色、圆角、空心和 icon 版本的 button:

[普通按钮](){.button} [圆角普通按钮](){.button.radius}

[空心](){.button.ghost} [:fa-github: 前面带 icon](){.button}

Icon:FontAwesome

nodeppt 的 icon 支持 FontAwesome 语法:

span

代码修改自markdown-it-span,支持 attr语法,基本用法:

:span:
:span: {.text-span}

动效

nodeppt 一如既往的支持动效,2.0 版本支持动效主要是页面内的动效。

支持动效包括:

在需要支持的动效父节点添加.build或者在具体的某个元素上添加.tobuild+动效 class即可。

按照惯例,nodeppt 还支持animate.css的动效哦~

详细查看文件:site/animation.md和在线演示

使用强大的:::完成复杂布局

:::语法是扩展了 markdown-it-container 语法,默认是任意 tag,例如

:::div {.content-left}

## title

:::

Output:

<div class="content-left"><h2>title</h2></div>

还支持,tag 嵌套,除此之外,支持的组件包括:

基本语法是:

:::TYPE {.attrs}

## 第一部分

使用 hr 标签隔开

---

## 第二部分

这里的内容也是哦

:::

详细可以看 component 部分的 markdown 文件和在线演示

打印?导出 pdf?

chrome 浏览器,直接在第一页 command+P/ctrl+P 即可

高级玩法

如果上面

nodeppt.config.js

在 nodeppt 执行路径下创建nodeppt.config.js文件,可以配置跟webpack相关的选项,另外可以支持自研 nodeppt 插件。

默认内置的config.js内容如下:

/**
 * @file 默认配置
 */
module.exports = () => ({
    // project deployment base
    baseUrl: '/',

    // where to output built files
    outputDir: 'dist',

    // where to put static assets (js/css/img/font/...)
    assetsDir: '',

    // filename for index.html (relative to outputDir)
    indexPath: 'index.html',
    // 插件,包括 markdown 和 posthtml
    plugins: [],
    // chainWebpack: [],

    // whether filename will contain hash part
    filenameHashing: true,

    // boolean, use full build?
    runtimeCompiler: false,

    // deps to transpile
    transpileDependencies: [
        /* string or regex */
    ],

    // sourceMap for production build?
    productionSourceMap: true,

    // use thread-loader for babel & TS in production build
    // enabled by default if the machine has more than 1 cores
    parallel: () => {
        try {
            return require('os').cpus().length > 1;
        } catch (e) {
            return false;
        }
    },

    // multi-page config
    pages: undefined,

    // <script type="module" crossorigin="use-credentials">
    // #1656, #1867, #2025
    crossorigin: undefined,

    // subresource integrity
    integrity: false,

    css: {
        extract: true
        // modules: false,
        // localIdentName: '[name]_[local]_[hash:base64:5]',
        // sourceMap: false,
        // loaderOptions: {}
    },

    devServer: {
        /*
      host: '0.0.0.0',
      port: 8080,
      https: false,
      proxy: null, // string | Object
      before: app => {}
    */
    }
});

parser plugin

解析插件分两类: markdown-it 和 posthtml,

定义一个 plugin :

module.exports = {
    // 这里的 id 必须以 markdown/posthtml开头
    // 分别对应 markdown-it和 posthtml 插件语法
    id: 'markdown-xxx',
    // 这里的 apply 是插件实际的内容,详细查看 markdown-it和 posthtml 插件开发
    apply: () => {}
};

webslides plugin

WebSlides 插件需要写到一个 js 文件中,然后作为数组放到window.WSPlugins_中,然后通过在 md 页面的配置(yaml)添加 js 的方法引入。

js: - webslide_plugins.js
// webslide_plugins.js内容
window.WSPlugins_ = [
    {
        id: 'webslide_plugin_name',
        // 下面是对应的插件类
        apply: class Plugin {}
    }
];

参考WebSlides 文档

Template:自制模板

参考nodeppt-template-default。

然后使用nodeppt new username/repo xxx.md使用

What is this?nodeppt is a tool that turns Markdown files into web-based slide decks: you write slides in a .md file and present the result in a browser. Version 2.0 was rebuilt on WebSlides, markdown-it, posthtml and webpack.
So is it a desktop app like PowerPoint, or something else?It's a command-line tool rather than a desktop app: the source is a Markdown file, and nodeppt serves it locally or compiles it into a static HTML presentation you show in a browser.
How do I create and preview a deck?Install it with npm (npm install -g nodeppt), then run nodeppt new slide.md to scaffold a deck from an online template, nodeppt serve slide.md to preview it via a webpack dev server, and nodeppt build slide.md to compile the final output.
Any gotchas before using it for a real talk?It's Chrome-first: the README says the best experience is Chrome and compatibility with other browsers is explicitly not a goal. Exporting to PDF is done through Chrome's print dialog (Ctrl+P / Cmd+P) from the first slide.
Is this for developers, or can anyone use it?Realistically developers and tech speakers — you work in Markdown, a YAML config block and the terminal. The audience itself only needs a browser to watch.
Can I present without an internet connection?Yes — nodeppt build compiles the deck into a static output folder, and files in your public folder are fully copied into dist, so the finished presentation runs locally in the browser.
Can I add charts, flowcharts or math formulas to slides?Yes — three built-in plugins: ECharts for charts, Mermaid for flowcharts and KaTeX for math, enabled in the yaml plugins config. ECharts and Mermaid content is written with fenced code block syntax, and Prism handles code highlighting with selectable themes.
What animations can slides use?Page-level build animations: fadeIn, zoomIn, rollIn, moveIn, fadeInUp and slow. Add .build on a parent element or .tobuild plus an animation class on a specific element, and animate.css effects are supported as well.
Does it have a presenter mode with speaker notes?Yes — append ?mode=speaker to the URL for speaker mode with dual-screen sync. While presenting: arrows/Space/Home/End change pages, F toggles fullscreen, -/+ opens an overview, N shows speaker notes and Enter toggles the grid background.
Is nodeppt still actively maintained?No — the GitHub repository is archived, so it no longer receives updates or fixes. It still works for building and presenting decks, but plan around the lack of maintenance.
