Comparing Angular, React, Vue, and Vanilla-JS

Let's take an analytical look at several of the key library / frameworks and compare them to Vanilla JavaScript.

Concept

Basically, I want to explore these tools in various ways:

Installation Processes

Setup Processes

Code Management

Routing

Binding Props

Binding Events

Services (API Access, etc.)

Referencing Assets

Unit Testing

Code Execution (Build Process and Size)

To do this, four separate builds of the same project were implemented. There were three "frameworks":

Angular

React

Vue

And, the fourth build was Vanilla JS.

The core logic was complex enough to use several parts of the frameworks, but simple enough I could build this in a reasonable time frame.

Conclusions

There is a lot of data here and the first question I generally get as people look at the content is, "which library should I be using?"

My basic assessment is whichever fits your needs the best.

This is extremely vague; let's dig in a bit further.

From a general speed standpoint, all the library are about the same, so we need a different set of parameters to choose the best library.

These conclusions are my own opinion ...

Angular

Angular is geared to Test Driven Development and is well suited for Enterprise level development. Their documentation is excellent and the community is responsive.

React

React has suitable testing tools. Their documentation just got a major upgrade and their community can be best described as "fierce."

Vue

Vue has good test tools and reasonable documentation. The community is small but this can work as an advantage since changes don't come out as frequently as Angular or React; requiring less general updating of the code.

Vanilla JavaScript

Vanilla JavaScript is here for a reason. While it is not a library, with many of the more recent changes it has become a solid tool for development.

Recently, I worked with a client that had a CMS in-place and they had missed several upgrades to the core software. Upgrading was going to be an in-place replacement and very painful. I migrated them to a Vanilla JavaScript solution which keeps the software behind their site good for a long time.

Having given this example, Vanilla JavaScript is not a good solution for larger endeavors (although, I've seen some interesting implementations).

Finally ...

This article basically shows that many of the popular libraries are now more comparable than ever which allows organizations to truly select which pattern(s) work best for them.

Comparison Summary

Angular

VERSION: 12.2.0

Installation Processes

Installation is via the Angular CLI (ng) ...

The CLI can be updated via ng update ...

Setup Processes

A new project is started with ng new <project-name>. There are various options provided (routing and/or CSS).

ng new <project-name>

ng serve --open

ng test

ng build

Code Management

Angular Router

Binding of Props (via attributes)

Binding of Events (via attributes)

Services (built-in tooling)

Using http-get process as well as imports to retrieve JSON

Unit Testing

Built-in Unit Testing, as well as E2E testing. The CLI includes these as ng generate <type> <location/name> is used.

Code Execution

Build and Size:

Code: 19k

DEV Time: 8 Hours

Lighthouse Information

Performance: 71

Time To Interactive: 3.0s

Total Blocking Time: 170ms

First Contentful Paint: 0.4s

React

VERSION: 17.0.2

Installation Process

There is no real installation since the setup is via NPM/NPX.

Setup Process

Installation is via npx (installed with NPM) ... npx create-react-app <project-name>

npx create-react-app <project-name>^*

npm start

npm run build

npm test

^* npx -- runs a command from a local or remote npm package (SEE HERE).

Code Management

React Router

Binding and passing of Props (via attributes or functional level)

Binding of Events (via attributes using original attributes, e.g. onClick)

Services (trained to use cleaner data-model)

Using http-get process

Unit Testing

Jest is included in the base-build with one simple test.

This configuration allows for a VERY clean Unit Test and E2E Testing environment.

Comparison Summary

Conclusions

Basically, it all boiled down to the simple fact that there's very little difference in complexity, functionality, and testability between each of these approaches.

There's no significant difference in selecting one package over another when it comes to the factors examined in this article.

There is a lot of data here and the first question I generally get as people look at the content is, "which library should I be using?"

My basic assessment is whichever fits your needs the best.
