Slidev

Slidev renders Markdown files as interactive slide presentations. Supports Vue components, UnoCSS styling, Shiki code highlighting, Mermaid diagrams, and LaTeX math.

Quick Start

# Create new project
pnpm create slidev

# Or with npm (downloads each time, slower)
npm init slidev@latest

# Dev server
slidev --open

# Export to PDF
slidev export

# Build static SPA
slidev build

Entry file defaults to slides.md. Pass different file: slidev other.md.

Code Blocks

Shiki syntax highlighting with language tag:

```ts
const greeting = 'Hello, Slidev!'
```

Line Highlighting

```ts {2,3}        // Highlight lines 2-3
```ts {1-3,5}      // Highlight 1-3 and 5
```ts {1|3|5-7}    // Click-stepped: 1, then 3, then 5-7
```ts {*|1|3}{lines:true}  // With line numbers

Options

```ts {lines:true}              // Show line numbers
```ts {startLine:5}             // Start numbering at 5
```ts {maxHeight:'200px'}       // Scrollable with max height
```ts twoslash                  // TwoSlash integration
