I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

webview mobile detection parsing is-ua-webview is-webview user-agent

is-ua-webview

A super simple webview user-agent detector

Installation

$ npm install is-ua-webview

Usage

const isWebview = require("is-ua-webview");

// just for testing:
const assert = require("assert");

// Facebook App embedded page load
assert(
  isWebview(
    "Mozilla/5.0 (Linux; Android 4.4.4; One Build/KTU84L.H4) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/33.0.0.0 Mobile Safari/537.36 [FB_IAB/FB4A;FBAV/28.0.0.20.16;]"
  )
);

// Chrome/Android browser
assert(
  !isWebview(
    "Mozilla/5.0 (Linux; Android 4.4.4; One Build/KTU84L.H4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.135 Mobile Safari/537.36"
  )
);

Tests

Run tests

npm test

Why

This was built for a web service that wanted to add a logging point in case the page load came from inside a webview where cookies were possibly throw away (not treated the same as a SafariViewController or native browser load). The tests are lacking completeness as this tool was only being used to discover and add detection in logs. The author of this module is no longer the owner/maintainer of the production service that used this module, so if you are interested in using it, please consider adding more tests and make a PR with tests :)
