eslint-plugin-strict-null-checks

ESLint plugin that reproduces TypeScript's strictNullChecks behavior as lint rules, enabling incremental migration from strictNullChecks: false to true. Version 0.1.3 (stable, low activity) depends on typescript >=3.9.4. Unlike native tsconfig strictNullChecks, allows warnings instead of errors and can be gradually applied per file via ESLint config. Requires @typescript-eslint/parser with project option pointing to a separate tsconfig with strictNullChecks: true.
