validator.js VS lodash

To keep the focus of this guide on building our chat app, I'll skip the steps in setting up certain dependencies, such as Tailwind CSS for styling, Nano ID for generating strings used to create a short URL version of an original URL and validator for implement URL validation.

express-validator is a set of express.js middlewares that wraps validator.js validator and sanitizer functions.

For emails, a robust email validator from a well maintained package such as validator would be a good idea.

Regarding escaping brackets and ampersands - would you do this prior to storing the value in the DB? This would seem like the only way to do it, otherwise you are looking at escaping after DB queries or escaping in the client, neither of which I like. React automatically escapes strings but it's not something I want to leave to chance, and I do not want "dangerous" data in storage. validatorjs's escape() function would seem the best fit for the job.

Sorry, are you referring to this https://github.com/validatorjs/validator.js as a wrapper

+1 for lodash! It's like a superpower once you realize everything it can do. Another good one is validator.js.

I'm taking a Javascript course at the moment, and while it's truly fantastic, parts of the Mongo stuff could use some updating (already had to course correct with some syntax). I'm now getting an error I really don't know what to do with, and SO isn't helping in this case. Per the course, we're using validator (https://www.npmjs.com/package/validator). Most relevant code file:

emailIsValid uses the helper method isEmail from the validator package to assert that the provided email is a valid email format

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:
