Similar packages

Other packages similar to flow-bin

typescript

TypeScript is a popular static type checker for JavaScript developed by Microsoft. It offers a superset of JavaScript with optional static types, and it has a large ecosystem and community support. Unlike Flow, TypeScript requires a compilation step to convert TypeScript code into JavaScript.

prop-types

PropTypes is a library for runtime type checking of React props. It is less comprehensive than Flow or TypeScript as it only checks types at runtime and is specifically designed for React components. It does not provide the same level of static analysis and type inference as Flow.

eslint-plugin-flowtype

ESLint plugin for Flow type annotations. It provides linting rules for Flow type annotations, helping to enforce consistent style and catch potential issues. It complements Flow by integrating type checking into the ESLint workflow.
