# Check if the touch events are supported

True when the browser exposes touch events or reports touch points.

Canonical: https://1loc.dev/dom/check-if-the-touch-events-are-supported/
Version: 1.0.0
Runtime: JavaScript · modern browsers (DOM)
Verification: Usage lines executed in headless Chromium against the fixture markup; no external services
Updated: 2026-10-28

## Implementation

```javascript
function touchSupported() { return 'ontouchstart' in window || navigator.maxTouchPoints > 0; }
```

## Usage

```javascript
// Desktop Chromium without a touchscreen:
touchSupported(); // → false
matchMedia('(pointer: coarse)').matches; // → false
```

Lines marked → were executed in headless Chromium against the markup above, and each result was compared with the value shown. Lines marked e.g. are illustrative.

## Limits

- Touch support is not touch use: many laptops have both. For layout, the pointer and hover media features describe the primary input, as the last line shows.
- The original also checked DocumentTouch, an obsolete non-standard interface; maxTouchPoints is the standard signal.

The function does not validate its arguments. Add checks where it receives untrusted input.
