Migrating a React project to React Native — Best Practices and Things to Keep in Mind

Migrating a React project to React Native — Best Practices and Things to Keep in Mind

Introduction

React Native is a popular open source framework created by Facebook that allows developers to create cross-platform mobile applications with JavaScript. If you have an existing React project and are looking to migrate it to React Native, this blog post will provide best practices and tips on how to streamline your workflow.

This article will contain information on:

• Setting up your project environment
• Structuring your React project for migration
• Polyfilling Node functions in React Native
• Managing components

Set up your environment

The first step when migrating to React Native is to set up your environment. This includes installing the React Native command line interface (CLI), configuring your mobile device or simulator, and setting up any third-party libraries or plugins. Setting up your environment properly will help ensure a smoother transition to React Native. This is especially important when you are trying to migrate a cryptocurrency related project from react to react native as react native does not support some of the crypto classes, functions and plugins out of the box.

Structure your project

When migrating to React Native, it is important to structure your project in a way that is easy to manage. This means organizing your project into separate folders for components, styles, images, hooks, and any other necessary files. Keeping your project organized will help you to find files quickly and reduce the amount of time spent looking for them.

An easy way to ensure that your project is properly structured for migration is to ensure that a lot of your non-jsx functions, classes and files are modular and semi-framework agnostic and can be ripped out and placed into any project whether it be react or not. In the case of react native I would advise that you create custom hooks and service classes on the react side to make things easier for you to move and manage.

Polyfilling Node functions and classes

In some cases, React Native does not have the same Node.js functions and classes that are available in React. To make up for this, developers can use polyfills to make the same functions and classes available in React Native. Polyfills are JavaScript functions that are designed to mimic the behavior of the Node.js functions and classes, allowing developers to use the same code when migrating to React Native. This can help streamline the process of migrating a project, since developers don’t have to rewrite code to account for the differences between React and React Native. However, not all Node.js functions and classes can be polyfilled, so it is important to research which functions need to be replaced during the migration process. These polyfills are often times called shims. For more information on polyfilling the right functions and classes check out this github repo called rn-nodeify that helps in adding polyfills for most Node functions to your react native project.

Manage components

When migrating to React Native, it is important to keep track of all your components and how they interact with each other. This can be done by creating a component library that is organized according to the type of component. This will make it easier to find components when you need to make changes or add new features. Even though react components cannot be transferred to react native it is still advisable to manage and keep track of how your components interact with one another so that implementation in react native won’t feel like you’re reinventing the wheel.

Conclusion

Migrating a React project to React Native can be a time-consuming process, but with the right tools and techniques, it can be made easier. By setting up your environment, structuring your project, and managing your components, you can streamline your workflow and make your transition to React Native smoother.

Thanks for reading, that’s all for now. If you would like a much more in-depth guide on migrating a React application to React Native I would be happy to publish a more in-depth guide or post a YouTube video based on demand.
