src/apps/the-exchange/components/TokenLogo/TokenLogo.tsx (1)
56-60: Consider adding error handling for the chain logo as well.While you've implemented error handling for the token logo, the chain logo doesn't have similar error handling. For consistency, consider adding an error handler to the chain logo image as well.
<img src={tokenChainLogo} alt="chain-logo" className={`w-full h-full object-fill rounded-full grayscale ${!tokenChainLogo && 'hidden'}`} + onError={(e) => e.currentTarget.style.display = 'none'} />src/apps/pillarx-app/components/TokenInfoHorizontal/TokenInfoHorizontal.tsx (1)
78-82: Consider adding error handling for the blockchain logo.Similar to the token logo, the blockchain logo might also fail to load. Consider adding error handling for this image as well for consistent behavior.
<img src={blockchainLogo} alt="logo" className="w-full h-full object-contain" + onError={(e) => e.currentTarget.style.display = 'none'} />src/apps/pillarx-app/components/HorizontalToken/HorizontalToken.tsx (1)
88-92: Consider adding error handling for the blockchain logo.For consistency with the token logo error handling, consider implementing similar error handling for the blockchain logo.
<img src={blockchainLogo} alt="logo" className="w-full h-full object-contain" + onError={(e) => e.currentTarget.style.display = 'none'} />src/apps/token-atlas/components/TokenCard/TokenCard.tsx (1)
1-72: Consider creating a reusable hook for image error handling.This pattern of tracking broken images with a state variable appears to be duplicated across multiple components according to the PR summary. Consider creating a custom hook like
useImageErrorHandlingto reduce code duplication.// Example implementation function useImageErrorHandling() { const [isBrokenImage, setIsBrokenImage] = useState<boolean>(false); const handleImageError = () => setIsBrokenImage(true); return { isBrokenImage, handleImageError }; } // Usage in component const { isBrokenImage, handleImageError } = useImageErrorHandling(); // ... <img src={tokenLogo} onError={handleImageError} />

27-28: Good implementation of image error handling.The addition of the
isBrokenImagestate variable and the conditional rendering logic provides a robust solution for handling broken token logos. The implementation follows React best practices and ensures a consistent user experience.Also applies to: 38-38, 43-43, 52-52
src/apps/the-exchange/components/TokenLogo/TokenLogo.tsx (1)
21-22: Good implementation of image error handling.The implementation for handling broken token logo images looks good. The state tracking and conditional rendering provide an effective solution.
Also applies to: 30-30, 35-35, 44-44
src/apps/pillarx-app/components/TokenInfoHorizontal/TokenInfoHorizontal.tsx (1)
35-36: Good implementation of image error handling.The addition of the
isBrokenImagestate and the associated logic for displaying a placeholder when the image fails to load provides a good user experience.Also applies to: 54-54, 60-60, 69-69
src/apps/pillarx-app/components/HorizontalToken/HorizontalToken.tsx (1)
41-42: Good implementation of image error handling.The broken image handling using the
isBrokenImagestate provides a robust solution for displaying fallback content when token logos fail to load.Also applies to: 64-64, 70-70, 79-79
src/apps/token-atlas/components/TokenCard/TokenCard.tsx (3)
1-1: Good addition of the useState hook and isBrokenImage state.This state variable will effectively track image loading failures.
Also applies to: 22-23
41-48: Good implementation of image fallback logic.The condition now correctly checks both for the existence of the token logo and that the image hasn't failed to load. The onError handler properly sets the broken image state when loading fails.
56-60: Good fallback overlay implementation.The overlay text now correctly appears when either the token logo is missing or when the image fails to load.
src/apps/token-atlas/components/TokenGraphColumn/TokenGraphColumn.tsx (3)
53-53: Good addition of isBrokenImage state.This state variable will effectively track image loading failures.
137-144: Good implementation of image fallback logic.The condition now correctly checks both for the existence of the token logo and that the image hasn't failed to load. The onError handler properly sets the broken image state when loading fails.
152-156: Good fallback overlay implementation.The overlay text now correctly appears when either the token logo is missing or when the image fails to load.
