Write your first API using Node.js and Express: Connect to the database

Building a REST API with Node.js and Express: Connecting to a Database In the first tutorial, "Understanding RESTful API," we learned what REST architecture is, what HTTP request methods and responses are, and how to understand RESTful API endpoints. In the second tutorial, "How to Set Up an ExpressAPI Server," we learned how to build a server using Node's built-in http module and the Express framework, and how to route the application we created to different URL endpoints. Currently, we use static data to display user information in the form of a JSON source when the API endpoint is hit with a GET request. In this tutorial we will set up a

14 jQuery tips, reminders, and best practices to improve your skills

If there's one bad thing about jQuery, it's that the entry level is so incredibly low that it tends to attract people who don't even know JavaScript at all. Now, on one hand, this is awesome. However, on the other hand, it can also lead to some, frankly, disgustingly bad code (some of which I wrote myself!). But that's okay; coding so horribly bad that it would make your grandma gasp is a rite of passage. The key is to get over the mountain, and that's what we're going to talk about in today's tutorial. 1. Methods Returning jQuery Objects It is important to remember that most methods return jQuery objects. This is very useful and allows for linking functionality that we use frequently. $someDiv.a

WordPress Web Application Development Guide: Detailed explanation of available features (Part 7): Caching Technology

When building web applications, one of the most important things that we must always pay attention to is performance. As they say, performance is a feature. Whether you're a designer, developer, or user, you know this intuitively: when it comes to apps, we hate waiting. We get frustrated when things don't work fast enough, or we have to wait longer than we think we should. To this end, most modern web development frameworks can implement some type of caching through the use of certain APIs, and WordPress (albeit a base one) is no exception. So, as we continue to discuss why WordPress is a viable option as the basis for web application development, we will get to the core

Retargeting WordPress: Transferring Website from Multisite Network

Sometimes, a site has been created in a WordPress multisite network but needs to be moved to its own single-site installation. There are several situations where this might happen, including: The site has grown too large to be included in the network. The website needs to have its own IP address. The website owner is changing providers or taking over full management of the website itself. In some cases you may find that you can move your site out of multisite using a plugin or combination of plugins, but if this doesn't work you will need to move the relevant database tables. Moving a site out of a multisite network in this way is a tricky process because it involves isolating the database tables in the multisite database that are relevant to that specific site. But it's not impossible. What you need To follow this tutorial you will need: Wo

Polymer Composition Sharing: Part 1

In my last tutorial on the Polymer library, I explained how to take advantage of this great new tool to create reusable web components. The focus of this tutorial and using components is to help us develop in the following ways: Encapsulate most of the complex code and structure Allow developers to use simple and easy-to-use tag style naming conventions Provide a set of predefined UI elements to leverage and extend I Still fascinated by it and want to explore this further by checking out the new template released by the Polymer team that makes deployment and reuse even easier. Canonical Path One of the quirks of the Polymer development process that I didn't mention is the disconnect between developing a component and actually making it reusable by others. Let’s look at a snippet from my previous tutorial

Top free JavaScript charting libraries

Data is all around us. We use it to optimize performance, service delivery and efficiency. However, raw numbers are not always the best way to convey information.

JavaScript provides many free libraries that you can use to create charts on your website. In this article, we will create a list of the best free JavaScript charting libraries and provide a brief overview of their features to help you make an informed choice. 1.Chart.js When thinking about drawing charts on a website, one of the first libraries that comes to mind is Chart.js.

Use basic strings, numbers, and Boolean values

Don't be confused by the fact that strings, numbers, and Boolean literals can be considered objects with properties (for example, true.toString()). When these primitive values are treated as objects by trying to access their properties, JavaScript will create a wrapper object from the primitive's associated constructor so that the properties and methods of the wrapper object can be accessed. Once the property is accessed, the wrapper object is discarded. This conversion allows us to write code that looks as if the original value is actually an object. To be honest, when it's treated as an object in code, JavaScript converts it to an object so that property access can work, and then converts it back to the original value after returning the value. Key things to note here

Guide to Maintaining Advanced WP Projects – Part 4: Ongoing Maintenance

There are many important factors to consider when working on advanced WordPress-based projects.
