@alukach/slidev-addon-laser

A laser pointer for Slidev: draw a red trail that fades out behind the pointer. Strokes drawn in the presenter view also appear in the audience view.

Demo

Install

pnpm add @alukach/slidev-addon-laser

# slides.md headmatter
addons:
  - '@alukach/slidev-addon-laser'

Use

• Hold Shift and drag to draw.
• Or click the scribble button in the nav bar to turn the laser on, then just move the pointer. Click it again to turn it off.

In presenter mode the trail follows Slidev's synced cursor, so turning the laser on also turns on the presenter cursor.

Configure

In the headmatter:

themeConfig:
  laserColor: '#ef4444'  # any CSS color
  laserWidth: 6          # px
  laserFade: 900         # ms until the trail disappears
  laserEnabled: false    # true to start with the laser on

Compatibility

This addon imports a few Slidev client internals (shared state and the nav-bar IconButton), so it may break on a Slidev major upgrade. engines.slidev declares the tested range.
