I use CodePens in my blog posts and recently I noticed that there is an issue which prevents displaying CodePen embeds correctly. I use Contentful to manage blog posts content. Contentful supports embedding content via Embedly. But for some reason, Embedly fails to show my CodePens in some cases. I couldn’t find the reason nor any way to load them. They just didn’t load. So I decided to stop hitting my head against the wall and make an implementation without Embedly.
This is a short example of how to catch all Axios HTTP requests, responses, and errors. Catching is implemented with the Axios feature called interceptors. It's possible to catch all requests before they are sent and modify them. Also, responses and errors can be caught globally. For example, interceptors are useful when you want to modify request headers before a request is sent or you are implementing some kind of global error handling system.

I have worked in the web industry since 2005 as a front-end and back-end developer. I created my first websites in the '90s. Here is a story how I got tangled in the web and how I ended up to work as a web developer. There have been three major occurrences which have paved the way for my career.

Sometimes you don't have an option to crop images on the server side so you need to do cropping in the browser instead. Here are few examples how to create cropped image thumbnails using CSS only. All the examples are responsive and work for most image aspect ratios. Cropped images are scaled and centered to maximize visible area of image.

My new web development blog is here! My blog posts most likely will be front end oriented but you might find something related to back end coding and general development topics as well. Purpose of this blog is to share something I have learnt and help others to find solutions. I'm also going to use this blog as my personal notebook. Currently I have few topics on my mind and I'll try to keep posting actively.
