A curated directory of tools for converting between JavaScript type systems and schemas like TypeScript, Flow, GraphQL, and JSON Schema.
Type-o-rama is a curated directory and reference guide for tools that convert between different type systems and schemas used in JavaScript development. It helps developers find libraries to translate type definitions across systems like TypeScript, Flow, GraphQL, JSON Schema, Elm, and others, solving interoperability challenges in polyglot codebases.
JavaScript and TypeScript developers working with multiple type systems, API schemas, or data formats who need to maintain consistency across tools and languages.
It saves time by aggregating conversion tools in one place, provides clear compatibility matrices, and is community-maintained to stay current with the evolving ecosystem of type-related libraries.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The README features a detailed table showing supported conversions between over 15 type systems and schemas, making it easy to identify available paths at a glance.
Each conversion path links to specific libraries, such as flowgen for TypeScript to Flow and graphql-code-generator for GraphQL, providing direct access to tools with brief descriptions.
The project aims to be a neutral, community-driven index without promoting specific tools, and includes badges to encourage participation, as stated in its philosophy.
It extends beyond core type systems to include runtime types, property-based testing tools, and languages like PureScript, offering resources for diverse interoperability scenarios.
Some conversions, like Flow to Closure JSDoc, are marked with a sad emoji indicating no available options, highlighting incomplete support for niche use cases.
The directory lists tools without information on their maintenance status, activity levels, or community support, requiring users to independently vet each library.
As a community-maintained GitHub repository, updates depend on contributions, so it might not reflect the latest tool versions or new libraries promptly.
