As a JavaScript developer, there’s occasionally a need to remove duplicates from an array of values.
By using our knowledge of advanced data sets we can write a lot less code and take advantage of built in features in JavaScript.
Knex is a JavaScript / Node.js library that is designed to make working with relational databases easier. Knex.js is a SQL query builder.
It has the potential to make tdd and database versioning much easier.
If you have been working with technology for longer than a few weeks, you’ve probably heard about using “cloud computing” or “cloud providers”. Cloud computer is dramatically changing technology departments all over the world. Traditional data centres consisted of large amounts of hardware that were connected to a network and generally was on the same…
Here’s a simple gitignore file that I start with most NodeJS projects.
As a software developer, and technology manager, I’ve had a lot of experience in the past with variable website traffic.
In the past, I’ve worked on business to consumer information websites, I’ve worked on payment gateways and even on a few ecommerce sites.
One of the most beautiful things of the Salesforce platform is that almost everything can be queried. Lightning components can be queried pretty easily.
I believe that debugging is one of the most important technical skills a developer can have. In the average week, I probably spend anywhere from 20 – 30 percent of my time debugging. This is because my code isn’t perfect, sometimes it does legitimately only work on my machine or device.
As a software developer, I’ve always been interested in working on things that I could potentially use and benefit from. For a long time, that’s meant that I worked on little projects for things I could use at home or for various side hustles. A few months ago, I became aware of a startup located…
As humans, we use data every day. Sometimes when we use data it’s completely subconscious – we don’t even realize we’re doing it. When we count the number of emails in our inbox, we can predict just how busy our day is going to be.
Backend developers work primarily on the server side of development, typically any scripts, databases, or architecture. Code written by backend developers typically helps communicate database information to the browser or mobile app.
As a programmer, and technology manager I think it’s really important to use the right tools and technologies. There are times where I think jQuery is still really valuable but there are a lot of times where I don’t think it is valuable.
Over the years, I have been really blessed to work on a number of API developments and to be able to consume a lot of APIs as well whether the APIs were in finance, sales automation (salesforce), or other services. A lot of the APIs had really noticeable deficiencies which I feel really made using the API a lot more difficult than it had to be.
This blog article is really a look at years of experience with APIs and a first attempt to at trying to make them easier to use for the developer. It’s really important to take time upfront and design a great API because it has the potential to be a huge asset for the company, and also has the potential to also be the company’s greatest liability.
A public API will have to remain virtually the same basically forever, so you really only have one chance to get it right. This is because customers or other integrators typically won’t ever update. If your API doesn’t have versioning you’ll basically never be able to make breaking changes. As users use your API and as feedback is collected you should be evolving the API.…
Although, JavaScript: The Good Parts is nearly ten years old I would argue it’s still a pretty good book to read. Literally, as the title implies the book calls out the best parts of the javascript language and tells what parts of the language to avoid.…
It’s no secret that I absolutely love JavaScript and Node.js. For those that don’t know Node.js is a framework that is built on top of JavaScript.
Node.js is an open source JavaScript runtime environment that runs on pretty much everything. It’s a great environment for building fast scalable network applications.
Node.js uses an event driven model that makes it really efficient and really good for real-time applications. Paired with serverless computing it’s fantastic for a lot of modern use cases.
In this article, I will go through the best practices for becoming a better Node.js developer. Over the last two years or so, I’ve interviewed and hired a lot of developers for the startup I’m working at.…
In late 2014, AWS Lambda launched and has grown in widespread use since then. AWS lambda is a serverless computing technology which has been a game change for software development.
AWS Lambda is a service that makes it easy to build small scalable applications. Lambdas are small functions that are packaged up and sent to AWS. Using a framework like the serverless framework makes it fairly easy to work with and pretty efficient.
Lambda is event driven. It works by responding to events whether they be timed, API driven or responding to events within AWS. One of the most common examples of using lambda is to resize images that have been uploaded to an S3 bucket.
Lambda is stateless meaning that every time a function is triggered, it is a completely new environment.
There’s so many reasons to use AWS Lambda. It’s easy to get started with it, it’s massively flexible, it is very scalable and more. …
I’ve been programming for a long time, and I’ve tried a lot of editors over that time. As a developer, I believe that my editor is the most important tool I have. At least half of what I do is done in my editor, a really terrible editor can even lead to injuries. Having a bad editor that isn’t working with my workflow leads to a lot of stress and wasted time. I was happy with Visual Studio for the most part, it could do everything I needed as long as I stayed on the microsoft stack. I find VS Code to be different, very different.…
Most software projects need to talk to a database at some point – they usually do GET queries for data, update a field or create a record. In the past, people would write raw code that communicated with the database and built an object or some code representation of the data that they would manipulate. This lead to an incredible amount of duplicated code for every project that usually had some subtle bug that was present in all libraries. …
One of the most important parts of building scaleable systems quickly is to find work that others have done and use it as part of our system. Using packages others built and assembling it with your business rules and logic is a lot like putting together pieces of Lego but following your instructions.
One of my favourite parts of React is that there’s usually hundreds of small open source components that can be used and usually easily modified to suit my needs. For example, there’s dozens of really well done date/time pickers that usually require no effort to put into place.…
Design patterns have been around for a long time in software development. Design patterns are basically a standard approach to solving a problem that can be found constantly in software development. Patterns are typically used for creating reusable designs, and defining the interactions between different objects or subsystems. I like to think of design patterns as a structured approach to software development and a very good way of improving communication between software developers. …
JavaScript has forever changed the way that websites are built. Even in it’s early days, it was being used to validate forms before data was submitted to servers. In the last 5 to 10 years, we no longer needed to do full page refreshes because of JavaScript which made the web feel faster and more responsive.…
