React Suitelet Documentation

NetSuite Suitelets are powerful scripts that allow developers to create custom app-like pages within the NetSuite environment. However, despite their flexibility, Suitelets are limited in terms of frontend capabilities, and complex customization can quickly become difficult to manage and maintain. NetSuite does offer tools to help manage large projects, such as splitting functionality across multiple scripts and rendering HTML using the file module. Still, even these approaches can fall short for highly interactive or dynamic applications.

This is where React comes in. React is a modern frontend framework designed for building dynamic state-driven interfaces without the need for full page reloads. By integrating React into a Suitelet, we can create a fully functional single-page application that operates entirely within the NetSuite ecosystem. This approach enables the creation of rich and maintainable user experiences while staying within the NetSuite platform.

However, integrating React with NetSuite comes with a challenge: NetSuite does not support direct use of external libraries or NPM packages inside its scripting environment. Because of this, we need to build our React application outside of NetSuite, compile it into a single static HTML file, and then deploy that file into the NetSuite File Cabinet. From there, we can serve it to users via a Suitelet.

React App Setup

This guide walks you through that entire process, from setting up a React app and configuring a bundler like Vite, Rollup, or Webpack, to rendering your compiled HTML via a Suitelet. We’ll also explore more advanced topics like:

• Handling React routing inside NetSuite
• Creating an API layer to communicate with NetSuite backend scripts
• Best practices for maintainability and performance

With this approach, you’ll be able to create truly modern interfaces while staying fully within the NetSuite ecosystem.
