Lazy Loading in Angular 6

This is a quick video of lazy loading working for Angular 6 routes. It is used when routing to feature modules, and stops the modules being initiliased before they are needed. const routes: Routes = [ { path: 'customers', loadChildren: './customers/customers.module#CustomersModule' } ] Is how a...

Content Lord - Instagram posts from Slack

I just wanted to show what this little application looks like from my side, as I’ve been using it for almost a year now and I’m quite pleased with it. https://instagram.com/bitcoinmemes is the Meme page I post images to with this. The fact I had just...

Project Zeus

Laravel Inverse Seed Generator

Laradock, Laravel, Sequel Pro Demo

MacBook Pro fans spinning while serving Angular

Differences across PHP versions

Now PHP 7.2 has arrived, and the previous versions are still in use, as shown above [1], I thought I would cover the differences between the versions now out there. I will be highlighting what I see as the...

Updating curl manually on Ubuntu

I wanted to update curl, but the version available on 16.04 of Ubuntu was 7.47.0, (not the latest 7.57.0) so the nice apt-get method wasn’t an option. Download the latest release from http://curl.haxx.se/download.html to your home...

HTTP API Methods

SEO Links

Hyper vs iTerm2

The Power of nohup

nohup allows is to run a command, close our connection, and still have the command run on the server - very powerful. I’ve used this at times I know I have a command that will take a long time to run, but I need to close my...

Digital Ocean Swap File

Digital Ocean is a great service, but by default no swap file is set on their droplets. I first realised this issue when my droplet was killing my composer update process. This can lead you to thinking you need a more powerful Droplet, but simply enabling...

Lazy load Disqus comments

I’ve implemented lazy loading of Disqus comments, it’s just a better way of handling comments loaded via javascript I believe. There is one potential drawback on SEO, but on the plus side there is faster page loads (better for SEO). I also like the fact I only...

SSL / HTTPS with Cloudflare

I get asked a lot of questions (I don’t ). Here’s a how-to on SSL with Cloudflare (they now provide this on their free plan): If you are only using Flexible SSL (HTTPS between cloudflare and end user) you do not want a redirect in htaccess /...

Why use Sass?

Admittedly Sass has been out for years now, but I did’nt feel an urgent need to write about, until now. On small projects CSS can seem fine. On large projects they can quickly become difficult to maintain. Want to change a colour used...

Auto reload with Grunt

What is Grunt? A ‘task runner’ - it helps us with reptitive tasks through automation, running from the command line. Why use Grunt? Reloading web pages after an code change does not take long but the time and extra actoins required...
