This tutorial follows on from Introducing Docker Containers to Computing Students and is part of a series. If this is your first time here, maybe start at the beginning.
Up until now, students have had access to creating Virtual Machines (VMs) on the Dundalk Institute of Technology network via our Xen Orchestra Appliance (XOA) at http://xoa.comp.dkit.ie. But VMs in the real world are rapidly being replaced by “containers”, so it’s time to take things to a whole new level.
To mark #WorldPasswordDay, today we will look at how to generate a strong password inside your PHP application.
Express.js provides an easy way to create web server and render HTML pages for different HTTP requests by configuring routes for your application.
You can create a simple live database search functionality utilizing the Ajax and PHP, where the search results will be displayed as you start typing some character in search input box.
Interpolating values is helpful if you need to pass a server-side variable to client-side JavaScript (or other languages that require it).
In the case of variables, numbers, strings, and the like, you can pass these types of variables directly into your JavaScript with bracket syntax plus an explanation point (so that the code inside the brackets is not evaluated.) This is useful for parametrizing JavaScript code that require something from your server.
It’s possible to pass variables from your server into Pug for dynamic content or script generation. Pug templates can access variables passed to the res.renderfunction in Express (or pug.renderFile if you are not using Express, the arguments are identical).
Content interpolated with bracket syntax will be evaluated for code, the output of which is included in your HTML output.
Further to our previous tutorial, sometimes it may be necessary to nest HTML tags inside of each other. Element interpolation with Pug is done in a syntax similar to variable interpolation; square brackets instead of curly braces are used here.
Clean and organized HTML is what Front-end Developers always aim for. Well with Pug (formerly known as “Jade” ), a high performance and feature-rich templating engine, that’s easy to achieve. Simply put, Pug is a clean, white space/indentation sensitive syntax for writing html.
