This is a package that attempts to detect a browser vendor and version (in
a semver compatible format) using a navigator useragent in a browser or
process.version in node.
NOTE: Migrating from 1.x to 2.x or higher
Release 2.0 introduced a breaking API change (hence the major release)
which requires invocation of a
detect function rather than just inclusion of
the module. PR #46
provides more context as to why this change has been made.
const detect = ;const browser = ;// handle the case where we don't detect the browserif browserconsole;console;console;
Or you can use a switch statement:
const detect = ;const browser = ;// handle the case where we don't detect the browser
Adding additional browser support
The current list of browsers that can be detected by
not exhaustive. If you have a browser that you would like to add support for
then please submit a pull request with the implementation.
Creating an acceptable implementation requires two things:
- A test demonstrating that the regular expression you have defined identifies
your new browser correctly. Examples of this can be found in the
- Write the actual regex to the
index.jsfile. In most cases adding the regex to the list of existing regexes will be suitable (if usage of
undefinedfor instance), but in some cases you might have to add it before an existing regex. This would be true for a case where you have a browser that is a specialised variant of an existing browser but is identified as the non-specialised case.
When writing the regular expression remember that you would write it containing a single capturing group which captures the version number of the browser.
