This cookbook demonstrates custom error handling with error boundaries and custom error contexts.

Context Custom Error Cookbook

This cookbook demonstrates custom error handling in the context module.

What This Shows

This cookbook illustrates how to:

• Throw custom context errors
• Configure error handling in context filters
• Display user-friendly error messages

Code Example

import {
  FusionContextSearchError,
  enableContext,
} from '@equinor/fusion-framework-react-module-context';

export const configure: AppModuleInitiator = (configurator) => {
  enableContext(configurator, async (builder) => {
    builder.setContextFilter((items) => {
      if (items.length === 0) {
        throw new FusionContextSearchError({
          title: 'This is a custom error',
          description: 'Could not find any items in the context. This error is intentional',
        });
      }
      return items;
    });
  });
};

Understanding Custom Errors

Use FusionContextSearchError to throw user-friendly errors with:

• title: Short error title
• description: Detailed explanation

When to Use This

Use custom errors for:

• Better error messaging
• User-friendly error handling
• Context validation
