In this tutorial, we will build a simple Flask app that is primed and ready to deploy to Heroku. Once the bare bones of the app are built, we will guide you through the setup process on GitHub and Heroku so that you can start making automatic deploys in no time. But before we dive straight into the code, why choose Flask and Heroku in the first place?
Welcome to part two of this series. In the previous tutorial, we learned about multi-tenancy, including different multi-tenancy implementation strategies. We also started building a multi-tenant Phoenix link shortening app and added basic user authentication. In this final part of the series, we'll build the link resource, associate users to links, and set up the redirect functionality in our app.
When working with money in an application, ensuring everything is accounted for is important. In this post, we will explore some common methods and best practices of handling money in your Ruby app, and see how you can use money-rails to write maintainable money-handling code. Let's get started!
Hello there! My name is Maciej Mensfeld, and some of you might recognize me from my involvement in RubyGems Security, OSS commitments, or perhaps from Karafka: a multi-threaded, efficient Kafka processing framework tailored for Ruby and Rails. While I generally pen my thoughts on my personal blog, today's post is unique. This article results from a collaborative effort with the brilliant people over at AppSignal. To set the record straight, I don't work for AppSignal.
Apps built with Elixir can support massive scalability, real-time interactivity, great fault tolerance, and the language's syntax is actually a joy to use. Elixir is a natural fit for applications such as chat apps, data dashboard apps, and anything needed to support a large userbase. In this article, we'll use Elixir — specifically, the web framework Phoenix — to build a multi-tenant link shortening app. Let's get started!
To update a document in MongoDB, I used to fetch it, update the values, and save back the entry. I would question the need for an update method. Looking back, it's evident that performance optimizations were hardly a concern when working on a personal project. Working with a larger dataset is a whole different story, though. This is where no-code tools can't help. In this article, I'll share some of my learnings when it comes to working in MongoDB with millions of documents.
In parts one and two of this series, we only dealt with the pure CRUD aspects of using SQLite as a production database. In this post, we will explore the world of queue mechanisms, using SQLite as the pub/sub adapter for ActiveJob. Let's make use of LiteJob to handle incoming webhooks in our Rails application.
Because of the asynchronous nature of Node.js, it's crucial you set timeouts to ensure the responsiveness of your application. Node.js timeouts help prevent indefinite waiting and let your backend handle situations where tasks take longer than expected. Thanks to timeouts, you can control the maximum duration allowed for incoming and outgoing requests. In this article, we'll look at the different types of timeouts and how to set them in vanilla Node.js and Express.
In the previous part of this series about validating data at the boundary of an Elixir application, we covered a few general programming tactics to try and reject invalid and unexpected data in our software. Continuing with that subject, we'll now explore how two libraries, namely Ecto and NimbleOptions, can further assist us. Let's get started!
Deno and Bun are two JavaScript runtime newcomers that aim to undermine Node.js. These alternatives have gained popularity for their innovative approach to server-side development with JavaScript. But the real question is: what do they bring to the table compared to Node.js? In this post, you'll learn what Deno and Bun are, what they offer, and how they address some long-standing drawbacks in Node.js. We'll shed light on specific use cases where Deno and Bun excel.
