The article showcases ~7 eslint rules for TypeScript that can greatly improve your codebase. The @typescript-eslint/no-unsafe-* rule pack is highlighted as a powerful tool to eliminate the usage of 'any' type in your codebase. It goes beyond the limitations of the noImplicitAny tsconfig option and catches narrow usages where the type of a function parameter is not specified. Another important rule mentioned is @typescript-eslint/no-explicit-any, which requires you to explicitly write out the type 'any' and disable linting for that line of code. This rule helps in maintaining a clean and type-safe codebase. Additionally, the article introduces @typescript-eslint/no-floating-promises, a rule that detects unhandled promises and helps in preventing 'Uncaught (in promise)' errors. Developers can enable these rules to improve code quality and eliminate potential bugs. Stay up-to-date with the latest TypeScript linting techniques and unleash the power of eslint rules in your projects.
