React Vs LWC for Salesforce Web Development (Beta)
LWC remains the optimal framework for building integrated, reusable components within the Salesforce Platform. While Salesforce Multi-Framework (Beta) broadens developer choice, they serve different purposes:
-
LWC: Choose LWC for native Salesforce platform integration. With LWC, you get built-in security, data binding, and the ability to create highly reusable, composable components that function seamlessly within Lightning Experience, Experience Builder sites, and Salesforce mobile apps.
-
React (Beta): Choose React for self-contained single-page applications (SPAs) or highly customized experiences using Salesforce as the host and data source.
| Feature | Lightning Web Components (LWC) | React (Beta) |
|---|---|---|
| Salesforce Integration | Deep, native integration with the Salesforce Platform. Automatic data binding, security, and access to platform services such as Lightning Data Service and Apex. | Excellent for building full page applications or custom experiences hosted via Salesforce Multi-Framework, giving developers the choice to leverage their existing React expertise and libraries. |
| Performance | Optimized for the Salesforce Platform, often leading to better performance within the Salesforce UI. | High performance for complex UIs, but performance within the Salesforce ecosystem depends heavily on API design and data retrieval strategies. |
| Security & Governance | Enforces platform security and compliance standards automatically. Built-in mechanisms for managing state and platform interaction. | Security is managed externally; developers must implement and maintain custom security best practices and secure API calls. |
| Learning Curve | Relatively low for developers familiar with modern JavaScript and HTML; syntax is standard-based. | Low to moderate, depending on familiarity with the broader React ecosystem (e.g., state management, routing). |
| Component Reuse | Excellent component-level reuse, referential integrity, and seamless integration within the Lightning Experience and across LWC projects. | Component reuse is fundamental within the React application/static site. Integration of React components in Lightning Experience and other LWC-based environments requires Micro-Frontend support (Developer Preview). |
