If you need to search or filter an array of objects, then this article will show you the most common ways of doing so using JavaScript’s built-in functions.

Find Vs Filter

Just to be clear finding and filtering produce different results.

• filter will return multiple values: all matching values

Example data

If you want to follow along, this is the example data I will be using.

data.json

[ { "id": 1, "name": "Joe Bloggs" }, { "id": 2, "name": "Jane Doe" }, { "id": 3, "name": "John Doe", "address": { "street": "21 Lime Street"…

When using Keycloak in a development environment, all the connections to your app, database, and Keycloak are made on your internal network. When you put your app into production, then your users may well be accessing your Keycloak server from outside your network. This is especially true when developing Single Page Applications SPA’s.

It is common practice to run the Keycloak server over HTTP behind a reverse proxy, which in turn provides your users with the HTTPS connection to keep their credentials private. This is where problems can start to arise with mixed content error messages.

There are still a lot of Developers and IT Professionals that have no experience with Docker. My personal experience is they think Docker is complex and challenging to manage.

In this tutorial, I’m going to demonstrate how to get Docker up and running quickly and how to simplify Docker management with the Web-Based graphical management tool, Portainer.

Docker vs Virtual Machines

Before we start, a quick overview of the difference between Docker and Virtual Machines might be helpful. If your already familiar with Docker just skip this section.

A Virtual Machine (VM) is an encapsulated operating system, running on top of another operating system…

I have spent most of my career in the IT industry in varying roles, but what I love most is development. It offers the most opportunities for creativity and innovation, especially web development.

In this article I will take you through some of the skills you need to be a great developer.

Languages

You can never have too many languages under your belt. On the other hand, it’s no good being a Jack of all trades and master of none.

You should be a Ninja with one language and a challenger with one or two others. Have a good understanding of…

In this article, I will show you how simple it is to create an SMTP server using NodeJS and be up and running in a few minutes. You can then send emails to your node application, either as a method of remote control or for 1001 other reasons.

An SMTP receives emails from other email servers or email clients. If you want an application to process emails in realtime, then your own SMTP server is the way to go. …

Object storage is amazingly versatile. We normally associate it with AWS S3, but Object Storage can also be run on your private network with MinIO. In this article, I’ll show you how to install MinIO using Docker and also on a Mac using homebrew.

MinIO has an API which is compatible with Amazon S3. This will allow you to develop applications locally and later, easily port them to AWS or you can use MinIO as your primary object store in production.

Prerequisites

You can code along with this tutorial on any operating system If you have Docker and docker-compose.

GridFS stores files in a MongoDB database. The maximum size of any one MongoDB document is 16MB. GridFS allows for much bigger files to be stored. It achieves this by breaking each file into chunks of 256K. Each fragment is stored as a separate document. One additional document is also created — this store’s metadata about the file and which documents hold each part of the file.

S3, in technology terms, is known as object storage architecture. It is often associated with Amazon Web Services, but alternatives exist, such as MinIO. Each object is a self-contained container comprising of data…
