Devise VS lodash

However for smaller apps it might be an overkill. In "real-life" production systems, overengineering is one of the biggest crimes. This is true any framework and technology, so in Rails you might want to use Rodauth since it is big and interesting and challenging, but then again, if you are building a simple greenfield MVP you do not have the time or need, for a big, complex solution. In those cases Rails developers usually go for Devise. It is one of the most known Rails gems, in multiple Rails surveys it was both number 1 in popularity, likability and "most frustrating" rankings.

Since Rails 7, there's more and more tooling that enables us, developers, to roll our own authentication. Devise is great and has been an amazing companion over the years. It also has this neat little feature - an authenticated route constraint which "hides" certain routes from people that are not signed in.

As much as this article is about user authorization, there's something important we need to cover: user authentication. Without it, any authorization policies we try to define later on will be useless. But there is no need to write authentication from scratch. Let's use Devise.

With around 50 new gems released daily, it is common to use trending libraries for managing everyday tasks. You probably use Devise for authentication, Cancan for authorization, Kaminari for pagination, or run tests with Rspec.

Devise is an authentication library built on top of Warden, a Rack-based authentication framework.

In this article, we will explore how to implement authentication in a Rails 7 application using the popular devise gem. Authentication is a crucial aspect of web development, allowing users to securely access and interact with your application. By following this step-by-step guide, you will learn how to set up devise, configure authentication routes, create user models, and enhance your application with authentication features.

Lodash.js is like the Swiss Army knife for JavaScript developers. Need to manipulate data structures or dabble in functional programming? Lodash is here to save the day with its arsenal of utilities. It's all about making your code cleaner and your life easier, which is probably why big guns like Google and Airbnb have it in their toolkit.

lodash - utility library enabling things like deep object comparison that aren't easy to do with javascript out of the box. docs

Lodash is a widely used JavaScript utility library that provides a plethora of functions to simplify common programming tasks. From manipulating arrays and objects to handling edge cases and implementing functional programming paradigms, Lodash offers a comprehensive toolkit for JavaScript developers. In this beginner's guide, we'll learn how to get started with Lodash and leverage its functionality to write cleaner, more efficient, and more maintainable code.

5. Lodash

If you want even more sophisticated equality checks like deep comparisons, there's the: lodash.iseQual library that'll do this for you out of the box. At least now you do have a bit of clarity on what's happening under the hood, so there's no harm in using a library.

It's also important to ensure that you're importing libraries correctly, so webpack can perform tree shaking effectively. For example, let's import lodash, as follows:

Lodash is awesome! It’s a JavaScript library that helps you do many things with data. You can use Lodash to manipulate arrays, objects, JavaScript strings, numbers, and more. It’s easy to get Lodash in your project. You can use npm or a CDN to install and import it. Here’s how:

Think of RxJS as Lodash for events.

lodash and You Might Not Need Lodash

A lot of Lodash functions are implemented as combinations of other Lodash functions, so importing a single function actually imports half of Lodash under the hood:
