![]() The parse method returns a Agent instance which contains all details about the example for parsing both the useragent header and a optional js useragent var agent2 = useragent.parse(req.headers, ) var agent = useragent.parse(req.headers) Information in different predefined formats. The parser returns a Agent instance, this allows you to output user agent The user is browsing the web using the Chrome Frame extension. The user agent string that you see in the browser, this can be send from theīrowser using a xhr request or something like this. The other argument is optional and should be Should the user agent string that is known on the server from the The function accepts 2 arguments, both should be a string. This is the actual user agent parser, this is where all the magic is happening. Npm install request -save useragent.parse(useragent string) Use this feature you need to add yamlparser and request to your package.json npm install yamlparser -save Location it will just fall back silently to the shipped version. If it fails to compile or load it from the remote ![]() This will async load the database from the server and compile it to a proper Paranoid and always want your RegExp library to be up to date to match withĪgent the widest range of useragent strings you can do: var useragent = require( 'useragent') Library or you can fetch it live from the remote servers. The useragent library allows you do use the automatically installed RegExp Include the useragent parser in you node.js application: var useragent = require( 'useragent') The -save flag tells NPM to automatically add it to your package.json file. NPM installed on your system you can download it from Installation is done using the Node Package Manager (NPM). Module: " useragent" is the user agent fastest parser. All thisĮngineering effort has been worth it as this benchmark shows: Starting the benchmark, parsing 62 useragent strings per run Executed benchmark against node module: " useragent"Ĭount ( 61), Cycles ( 5), Elapsed ( 5.559), Hz ( 1141.3739447904327)Įxecuted benchmark against node module: " useragent_parser"Ĭount ( 29), Cycles ( 3), Elapsed ( 5.448), Hz ( 545.6817291171243)Įxecuted benchmark against node module: " useragent-parser"Ĭount ( 16), Cycles ( 4), Elapsed ( 5.48), Hz ( 304.5373431830105)Įxecuted benchmark against node module: " ua-parser"Ĭount ( 54), Cycles ( 3), Elapsed ( 5.512), Hz ( 1018.7561434659247) Or on demand parsing for Operating System and device information. Pre-compiled library that contains all the Regular Expressions and uses deferred The module has been developed with a benchmark driven approach. ![]() Most likely parse out the wrong browser name or confuse the render engine version This is why regular user agent parsers have major issues because they will This database is needed to ensure that every browser isĬorrectly parsed as every browser vendor implements it's own user agent schema. String with high accuracy by using hand tuned dedicated regular expressions forīrowser matching. Useragent originated as port of 's user agent my guns fit me well go bang the game die what else do you want, do not listen to 2 bit snobs as i call em.Useragent - high performance user agent parser for Node.js went spotlighting rabbits with baikal other night i took 15 shells in 6s brought back 9 rabbits and still had 2 shells left. ![]() i just brought a stoeger u/o deluxe for $840 au as we just got 2 lots of tax hikes on guns still cheapest on the market though, i brought steoger as we have to use steel shot now, steel crap through tight chokes on baikal, first shot through stoeger brought down a black duck from 70 yards up using 4s in steel & mod choke very very happy with stoeger, do not listen to poeple who rubbish cheaper guns, my grandfather allways said there are more good guns out there than good shots. Hi i am in australia i brought a baikal u/o when i was about 15 kids at school laughed because i brought a cheap gun, at 16 duck opening morning i was home at 9.00 am 42 ducks on my belt using 7s in baikal brand shells, i am 44 now still got it and i bet i have shot more game than any of them, its been belted around wont shoot properly unless i kick it around in the dirt a bit and then its happy and ready to go, just joking.
