# ESLint Fix Patterns How to resolve specific ESLint errors in this project. ## no-void Don't use the `void` operator in event listener functions. Instead, make the function `async` and `await` the promise. ```tsx // BAD const handleClickNavigate = () => { void navigate('/path'); }; // GOOD const handleClickNavigate = async () => { await navigate('/path'); }; ``` ## canonical/export-specifier-newline vs prettier conflict Use inline `export const` declarations instead of a grouped `export { ... }` statement to avoid circular fix warnings between these two rules. ```tsx // BAD, causes circular fix between prettier and canonical export {DAYS, DURATIONS, FITNESS_GOALS}; // GOOD, declare with export directly export const DAYS = ['mon', 'tue'] as const; export const DURATIONS = [15, 30, 45] as const; export const FITNESS_GOALS = ['weight_loss'] as const; ``` ## no-shadow trailing underscores ESLint's `no-shadow` autofixes by appending `_`. Once shadowing is resolved, remove the trailing `_`. ## sonarjs/deprecation Never suppress with `eslint-disable`. Always fix the underlying deprecation. Common case: Zod v4 deprecated `z.string().email()` in favor of `z.email()`. ```tsx // BAD, suppressing the warning // eslint-disable-next-line sonarjs/deprecation email: z.string().email(), // GOOD, use the non-deprecated API email: z.email(), ``` ## you-dont-need-lodash-underscore/\* Use native JavaScript instead of lodash/underscore equivalents. ```tsx // BAD import _ fr...
