RegEx Snippets

Extract URLs

Find all links

Works pretty well in capturing the full URL when using this in a search (like in Sublime Text 2). (https?|ftps?)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/?

Let's Encrypt

Examples of getting certificates from Let's Encrypt working on Apache, NGINX and Node.js servers.

Obtain certificates

I chose to use the manual method, you have to make a file available to verify you own the domain. Follow the commands from running

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

Note: Some of these shortcuts have been remapped for my own convenience (Preferences->Keymap). These are Mac shortcuts, just use the Windows/Linux equivalent of the Cmd/Option/Ctrl/Del keys.

####Search, Go to, Navigation ####

Cmd + P - Search file

Cmd + Shift + O - Search everywhere

(I swapped the above two recently because I use Cmd + P to search for files most of the time).

Deploying a Production ready React-Express app on AWS

In this tutorial, I will be going over to how to deploy a Javascript app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app AlgoAcademy (a resource for reviewing algorithms and data structures) and we wanted to share with other developers some of the lessons we learned along the way.

Following this tutorial, you will have an application that has:

• A React frontend, Express backend
• An AWS EC2 server configured to host your application
• SSL-certification with Certbot
• A custom domain name

Hacky way to detect if app was launched in standalone mode in Chromium (with manifest.json) without problems with AppCache (and possibly ServiceWorker).

As suggested on one of the Google Developers sites, one may use search params in start_url of the manifest.json to notify page about that it was launched in standalone mode: start_url: '/?standalone'.

This works well unless your page uses AppCache (or ServiceWorker). In case of AppCache, every url with different search params is treated as separate entry in cache. So if you have listed / path in AppCache and naively used start_url: '/?standalone' in your manifest.json, then your Web App won't work offline from the Home Screen.
_With ServiceWorker, however, there is few ways to fix this directly in its code, like ignoreSearch option for match() method (currently not supported in Chromium) or just traversing cache entries manually and comparing new URL(event.request.url).pathname with stored request `new URL(...).path
