Knockout is a minimalist, mature and proven library for creating web applications.
It isn’t as feature rich as some of the more modern libraries & frameworks but it does what it does well, primarily being binding HTML elements against a data model.
Even in 2019, I believe Knockout has its place and is still used on some very large projects, including Microsoft’s Azure Portal.
TypeScript provides a huge amount of benefits over JavaScript including type safety, improved IDE tooling and additional constructs like interfaces and enums.
If you have an existing project that uses Knockout, you can move over to TypeScript now and start enjoying these benefits.
This article will start with creating a new project that uses webpack and Babel to transpile TypeScript down to JavaScript (ES5).
We’ll then cover using TypeScript and Knockout’s type definitions to create view models, components and bindings that are strongly typed.
This article covers how to start using TypeScript modules in an existing project alongside JavaScript modules.
If you have a large project, it may not be feasible to move to TypeScript all in one go.
Gradually migrating provides more flexibility and allows you to, for example, use TypeScript just for new code or “upgrade” modules when there are changes to existing code.
TypeScript provides some huge benefits like types support, better IDE tooling and additional constructs like interfaces and enums so why not start making use of these now.
When using Vuex with TypeScript, you typically use the @Getter decorator from the
binding helpers package vuex-class.
This is a more declarative approach over using this.$store.getters.*.
This article covers designing and developing a Weather App webpage using Responsive Web Design (RWD) techniques.
This article will cover creating wireframes for our page so we can visually see how the app will be laid out on different devices and then we’ll create some high-fidelity designs.
Next we’ll develop the responsive webpage making use of CSS media queries to alter the layout and design to fit any device screen size from a mobile phone to a large desktop.
This article covers creating a blog from scratch using the Node.js powered static site generator
Eleventy
(aka 11ty).
Eleventy is a relatively new project that came out in 2018 and is quickly gaining traction. It’s up to an impressive 3,000 stars on GitHub already.
Eleventy keeps things simple and as you’ll see, really enables you to quickly create a fully functional site.
The blog we’ll create will contain a homepage with excerpts from our posts that can be clicked on to read the full post. Once we have our blog up and running, adding new posts will be as simple as adding new Markdown files. Eleventy will take care of generating HTML pages seamlessly for us as well as updating the homepage.
I recently faced an issue where the MIME type for a .mp4 file was being returned from an Azure Web App as application/octet-stream and not the video/mp4 I was seeing locally.
Code
var filename = "test.mp4";
var mimeType = MimeMapping.GetMimeMapping(filename);
Output
Locally: video/mp4
In Azure: application/octet-stream
The Internet is a fantastic medium where people can share information, knowledge… and cute cat photos freely and inclusively.
HTML is one of the key technologies for the World Wide Web and when used correctly, largely ensures content is accessible to all.
Unfortunately, with the rush to create sophisticated JavaScript rich web pages, the fundamentals of good semantic markup are often overlooked to the detriment of web accessibility.
One way to drastically exclude users from your site is to add JavaScript click handlers to non-interactive elements such as <div> and <span> tags.
