I am looking to create my Node.js application to cater to various user agents such as Web, iOS, and Android, each requiring different data (e.g., filter fields specific to certain user agents). Should I create separate routes for each user agent or implement conditional logic within the same route based on the user agent? If I need to use the same route, do you have any recommendations for node modules that would be suitable?
To analyze the user-agent information in the 'req.headers['user-agent']' variable using the 'useragent' package, you can follow the same route as mentioned below.
For instance:
const useragent = require('useragent')
// ...
const ua = useragent.is(req.headers['user-agent'])
if (ua.firefox) {
// perform actions related to Firefox
} else if (ua.chrome) {
// perform actions related to Chrome
}
