In @app/views/RoomInfoView/index.tsx:
- Around line 134-136: The OS/browser strings set from
Bowser.getParser(visitor.userAgent) can include undefined version fields,
leading to outputs like "Windows undefined"; update the assignments that set
params.os and params.browser to defensively handle missing name or version by
reading ua.getOS() and ua.getBrowser(), defaulting name/version to empty string
or omitting the version when undefined, and composing the final string
accordingly (e.g. use name only if version is falsy or join name and version
with a conditional). Target the code around Bowser.getParser, visitor.userAgent,
params.os and params.browser and ensure the final values never contain the
literal "undefined".

8-8: The Bowser import is correct and compatible with v2.13.1.Bowser.getParser(), Parser.getOS(), and Parser.getBrowser() are all supported in Bowser v2.13.1 with the correct return types matching the usage pattern in this file.
package.json (1)
54-54: Bowser version 2.13.1 exists on npm and has no known security vulnerabilities. The package is legitimate and actively maintained. No actionable changes needed.

🌐 Web query:
Bowser v2.13.1 getOS() getBrowser() return undefined properties API documentation
💡 Result:
Short answer: In Bowser 2.x (including v2.13.1) getBrowser()/getOS() are instance methods on a Parser returned by Bowser.getParser(...) (or new Parser(ua)), not top-level static functions. Calling Bowser.getBrowser() / Bowser.getOS() (or calling instance methods before parsing or with an empty UA) will yield undefined. See docs and parser API.
What to do
- Use the Parser API:
const parser = Bowser.getParser(navigator.userAgent);
const browser = parser.getBrowser(); // { name?, version? }
const os = parser.getOS(); // { name?, version?, versionName? }
or use parser.getResult() for the full parsed object. - Ensure you pass a non-empty UA and that parsing was not skipped (skipParsing=false) — otherwise properties can be undefined.
Sources
- Bowser docs / Parser API. [1]
- parser.js reference showing getBrowser/getOS return possibly undefined name/version fields. [2]

🌐 Web query:
Bowser getOSName() getBrowserName() getOSVersion() getBrowserVersion() methods API
💡 Result:
Short answer: These are methods on Bowser's Parser object. Call Bowser.getParser(userAgent) (or Bowser.getParser(window.navigator.userAgent)), then use getBrowserName()/getBrowserVersion() to get the browser name and version, and getOSName()/getOSVersion() (or getOS()) to get OS name/version. Example:
- const parser = Bowser.getParser(window.navigator.userAgent); [1]
- parser.getBrowserName(); // returns browser name string (e.g., "Chrome"). [1][2]
- parser.getBrowserVersion(); // returns browser version string (e.g., "116.0.5845.96"). [2]
- parser.getOSName(); // returns OS name string (e.g., "Windows" or "macOS"). [2]
- parser.getOSVersion(); // returns OS version string (e.g., "10.15.7"). [2]
- parser.getOS(); // returns { name: "...", version: "..." } if you need both. [2]
Notes: methods live on the Parser instance (Bowser.getParser(...)). See Bowser docs and the Parser API for details and examples. [1][2]

🌐 Web query:
Bowser v2.13.1 parser getOS() undefined properties when name version not available
💡 Result:
Summary: In Bowser v2.13.x the Parser.getOS() can return an empty object ({} ) when no OS parser matches, and Parser.getOSName() converts the possibly-undefined name with String(name).toLowerCase() — which produces the literal string "undefined" instead of an empty string. This explains why you see undefined properties / the string "undefined" when name/version aren't available. (bowser-js.github.io)
Fix/workarounds:
- Short-term (call-site): read the raw object and null-coalesce: const os = parser.getOS(); const osName = os.name ?? ''; const osVersion = os.version ?? '';
- Short-term (use API): avoid getOSName() in affected versions; use parser.getOS().name with null coalescing. (bowser-js.github.io)
- Long-term (library patch): change getOSName implementation to guard before String(), e.g.:
getOSName(toLowerCase){ const name = this.getOS().name || ''; return toLowerCase ? name.toLowerCase() : name; }
(Or wrap with String(name || '')). This prevents "undefined". (bowser-js.github.io)
If you want, I can draft a small PR patch or a one-line patch you can apply to v2.13.1.

Avoid using Bowser's convenience methods as fallbacks; they have a bug that produces the string "undefined".
The current fallback pattern (ua.getOS().name ?? ua.getOSName()) attempts to handle cases where getOS().name is undefined, but Bowser v2.13.1's convenience methods (getOSName(), getBrowserName(), etc.) have a bug: when the properties are unavailable, they return the literal string "undefined" instead of an empty string. This causes params.os and params.browser to contain invalid values like "undefined 116.0".
Instead, use null coalescing with empty strings:
params.os = `${ua.getOS().name ?? ''} ${ua.getOS().version ?? ''}`.trim();
params.browser = `${ua.getBrowser().name ?? ''} ${ua.getBrowser().version ?? ''}`.trim();Or apply .trim() to the final string to clean up extra spaces if either property is missing.

This PR reduces the app bundle size by removing unused / heavyweight dependencies and replacing them with a lighter, functionally equivalent alternative.
Summary
(~94.5 kB)(~1.29 MB)Added a lightweight alternative:
(~252 kB)The only usage of
ua-parser-jswas inRoomInfoView(Livechat visitor OS & browser parsing).This has been replaced with
Bowser, which provides the same required information (OS + browser) with a significantly smaller footprint and no functional impact.Why this change?
