React-Rails is a flexible tool to use React with Rails. The benefits:

• Automatically renders React server-side and client-side
• Supports Shakapacker v7
• Supports Sprockets 4.x, 3.x
• Lets you use JSX, ES6, TypeScript, CoffeeScript

While ShakaCode will continue to support this gem, you might consider migrating to React on Rails or React on Rails Pro with proper Node rendering.

Why? React on Rails code receives much more active development and testing. For example, consider the ReactRailsUJS implementation compared to the ReactOnRails Node package which is written in TypeScript. For another example, React on Rails has work underway to support the latest React features, such as React Server Components.

You can find migration to React on Rails steps here.

ShakaCode focuses on helping Ruby on Rails teams use React and Webpack better. We can upgrade your project and improve your development and customer experiences, allowing you to focus on building new features or fixing bugs instead.

For an overview of working with us, see our Client Engagement Model article and how we bill for time.

We also specialize in helping development teams lower infrastructure and CI costs. Check out our project Control Plane Flow, which can allow you to get the ease of Heroku with the power of Kubernetes and big cost savings.

Here's a testimonial of how ShakaCode can help from Florian Gößler of Blinkist, January 2, 2023:

Hey Justin 👋

I just wanted to let you know that we today shipped the webpacker to shakapacker upgrades and it all seems to be running smoothly! Thanks again for all your support and your teams work! 😍

On top of your work, it was now also very easy for me to upgrade Tailwind and include our external node_module based web component library which we were using for our other (more modern) apps already. That work is going to be shipped later this week though as we are polishing the last bits of it. 😉

Have a great 2023 and maybe we get to work together again later in the year! 🙌
