## Bowser
|
|
A Browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.
|
|
|
|
[](https://travis-ci.org/ded/bowser/)
|
|
|
|
So... it works like this:
|
|
|
|
``` js
|
|
if (bowser.msie && bowser.version <= 6) {
|
|
alert('Hello China');
|
|
}
|
|
```
|
|
|
|
## 1.0.0 breaking changes
|
|
`browser = require('bowser').browser;` becomes `browser = require('bowser');`
|
|
|
|
## Bowser Flags
|
|
Your mileage may vary, but these flags should be set. See Contributing below.
|
|
|
|
``` js
|
|
alert('Hello ' + bowser.name + ' ' + bowser.version);
|
|
```
|
|
|
|
### All detected browsers
|
|
These flags are set for all detected browsers:
|
|
|
|
* `name` - A human readable name for this browser. E.g. 'Chrome', ''
|
|
* `version` - Version number for the browser. E.g. '32.0'
|
|
|
|
For unknown browsers, Bowser makes a best guess from the UA string. So, these may not be set.
|
|
|
|
### Rendering engine flags
|
|
If detected, one of these flags may be set to true:
|
|
|
|
* `webkit` - Chrome, Android, iOs, BB, etc.
|
|
* `gecko` - Firefox, etc.
|
|
* `msie` - IE <= 11
|
|
* `msedge` - IE > 11
|
|
|
|
Safari, Chrome and some other minor browsers will report that they have `webkit` engines.
|
|
Firefox and Seamonkey will report that they have `gecko` engines.
|
|
|
|
``` js
|
|
if (bowser.webkit) {
|
|
// do stuff with safari & chrome & opera & android & blackberry & webos & silk
|
|
}
|
|
```
|
|
|
|
### Device flags
|
|
If detected, one of these flags may be set to true:
|
|
|
|
* `mobile` - All detected mobile OSes are additionally flagged `mobile`, **unless it's a tablet**
|
|
* `tablet` - If a tablet device is detected, the flag `tablet` is **set instead of `mobile`**.
|
|
|
|
### Browser flags
|
|
If detected, one of these flags may be set to true. The rendering engine flag is shown in []'s:
|
|
|
|
* `chrome` - [`webkit`]
|
|
* `firefox` - [`gecko`]
|
|
* `msie`
|
|
* `msedge`
|
|

|
|
* `ucbrowser` — [`webkit`]
|
|
* `qupzilla` — [`webkit`]
|
|
* `vivaldi` — [`webkit`]
|
|
|
|
For all detected browsers the browser version is set in the `version` field.
|
|
|
|
### OS Flags
|
|
If detected, one of these flags may be set to true:
|
|
|
|
* `mac`
|
|
* `windows` - other than Windows Phone
|
|
* `windowsphone`
|
|
* `linux` - other than `android`, `chromeos`, `webos`, `tizen`, and `sailfish`
|
|
* `chromeos`
|
|
* `android`
|
|
* `ios` - also sets one of `iphone`/`ipad`/`ipod`
|

|
|
* `bada`
|
|
* `tizen`
|
|
* `sailfish`
|
|
|
|
`osversion` may also be set:
|
|
|
|
* `osversion` - for Android, iOS, Windows Phone, WebOS, Bada, and Tizen. If included in UA string.
|
|
|
|
iOS is always reported as `ios` and additionally as `iphone`/`ipad`/`ipod`, whichever one matches best.
|
|
If WebOS device is an HP TouchPad the flag `touchpad` is additionally set.
|
|
|
|
### Browser capability grading
|
|
One of these flags may be set:
|
|
|
|
* `a` - This browser has full capabilities
|
|
* `c` - This browser has degraded capabilities. Serve simpler version
|
|
* `x` - This browser has minimal capabilities and is probably not well detected.
|
|
|
|
There is no `b`. For unknown browsers, none of these flags may be set.
