# Go/Golang package for parsing user agent strings [](https://godoc.org/github.com/mileusna/useragent)
|
|
|
|
Package `ua.Parse(userAgent string)` function parses browser's and bot's user agents strings and determins:
|
|
+ User agent name and version (Chrome, Firefox, Googlebot, etc.)
|
|
+ Operating system name and version (Windows, Android, iOS etc.)
|
|
+ Device type (mobile, desktop, tablet, bot)
|
|
+ Device name if available (iPhone, iPad, Huawei VNS-L21)
|
|
+ URL provided by the bot (http://www.google.com/bot.html etc.)
|
|
|
|
## Status

## Shorthand functions
|
|
|
|
Beside `UserAgent{}` struct and its properties returned by `ua.Parse()`, there is a bunch of shorthand functions for most popular browsers and operating systems, so this code:
|
|
|
|
```go
|
|
ua := ua.Parse(userAgentString)
|
|
if ua.OS == "Android" && ua.Name == "Chrome" {
|
|
// do something
|
|
}
|
|
```
|
|
can be also written on this way:
|
|
```go
|
|
ua := ua.Parse(userAgentString)
|
|
if ua.IsAndroid() && ua.IsChrome() {
|
|
// do something
|
|
}
|
|
```
|
|
|
|
## Notice
|
|
|
|
+ Opera and Opera Mini are two browsers, since they operate on very different ways.
|
|
+ If Googlebot (or any other bot) is detected and it is using its mobile crawler, both `bot` and `mobile` flags will be set to `true`.
