Do you have a Node.js project that you want to put into production but don't know how? In this tutorial, you'll learn how to deploy a Node.js and MongoDB application to Heroku. Before we get started, let's take a very quick look at Heroku and MongoDB.
Phoenix LiveView 0.18 just shipped, with lots of new goodies to make developing LiveView an even better experience. In this post, I'll take you through a lesser-known new feature - LiveView's new special HTML attributes - and show you how to write cleaner HTML with :if, :for, and :let. When we're done, you'll have an eloquent, ergonomic, and dynamic function component you can use to render a list anywhere in your LiveView app. Let's dive in!
Alongside performance and usability, you should always focus on security when creating any web application. Keep in mind that hacking techniques are constantly evolving, just as fast as technology is. So you must know how to secure your users and their data. This article will show you how to create a secure Rails application. The framework is known to be secure by default, but the default configuration is not enough to let you sleep well at night.
The XML data format has been around since 1996. It was first envisioned as a lingua franca (bridging language) for data to be serialized and read into completely disparate systems (with different programming languages, operating systems, and even hardware). It has been wildly successful in that goal. In software, though, 26 years is like a lifetime — and in hardware, it's an eternity.
Memory management has always been a source of huge concern in Computer Science. Each piece of software is assigned a small portion of a computer’s finite memory; this memory has to be well-managed (carefully allocated and deallocated). With its efficient automatic garbage collection mechanism, Node.js tries to handle the tedious task of memory management and free up developers to work on other tasks.
Serverless computing is an exciting alternative to hosting apps on the AWS cloud. In this four-part series, we’ll run through how to build AWS Lambdas with TypeScript, improve the dev experience, optimize it, and finally, use AWS Cognito for security. In this take, I would like to take you on a journey to explore AWS Lambdas using TypeScript. We will build a pizza API, use Claudia to help deploy the app, and use the AWS CLI tool to set up a DynamoDB database.
An application monitoring tool (APM) is not just useful for seeing how your application performs through graphs and visuals. We can go deeper and use an APM to understand how your application behaves in a certain environment. As developers, we should aim to be less reactive to errors and more predictive, avoiding crashes for end-users. One way to accomplish this is by using monitoring tools to debug our application when an error occurs.
Elixir v1.14 shipped earlier this month with a bunch of new goodies. In this post, we'll explore Elixir's new PartitionSupervisor. We'll take a look at some code that suffers from the exact bottleneck issue that partitions supervisors are designed to solve. Then, we'll fix that bottleneck. Along the way, you'll learn how partition supervisors work under the hood to prevent process bottlenecks. Let's get started!
A JSON Web Token (JWT) is an open standard (RFC 7519) that securely sends and receives data between parties (in the form of a JSON object). In this article, we’ll implement JWT authentication to secure a Node.js application. We’ll also find out what JWT is all about and build a demo app. Let's get going!
The latest Elixir release introduces new features to improve your developer and debugging experience. In this post, we'll take a look at the new dbg() functionality, along with some improvements to Inspect and binary evaluation error messaging. All these changes come together to make you an even more productive Elixirist. Let's get started!
