isEdge()

true when the current environment is Microsoft Edge — both flavours.

Signature(options?: DetectOptions) => boolean
MatchesEdge/, Edg/, EdgA/, EdgiOS/
Wins overisChrome() for Chromium-Edge UAs

Matches​

  • Legacy EdgeHTML (2015–2019) — UA token Edge/.
  • Chromium-Edge (2020+) — UA token Edg/, EdgA/ (Android), or EdgiOS/ (iOS).

Example​

import { isEdge } from 'get-browser';

if (isEdge()) {
  // Edge-specific code path
}

Why it precedes isChrome() in detect()​

Chromium-Edge advertises both Chrome/ and Edg/. Without ordering, both predicates would return true and detect() would have to make a tie-breaker call. Running isEdge first guarantees Edge wins.

import { detect, isChrome, isEdge } from 'get-browser';

const ua = 'Mozilla/5.0 (Windows NT 10.0) Chrome/140.0.0.0 Safari/537.36 Edg/140.0.0.0';

detect({ userAgent: ua });   // → 'edge'
isEdge({ userAgent: ua });   // → true
isChrome({ userAgent: ua }); // → false  (excluded by the Edg/ token)
