   A tool to Convert JSON schemas into TypeScript Deno classes▲43

   Hello all To preface this is just something I've been making as a learning exercise, so all feedback is appreciated.

Compression & Decompression: Compress and decompress your data. Validation: Built-in data validation using Ajv ensures your data adheres to the schema. Reusability: Once generated, the utility classes can be used in other Deno projects. It currently only supports a subset of JSON…

    Paradict – Streamable multi-format serialization with schema▲14

    Hi HN ! I'm Alex, a tech enthusiast. I'm excited to show you Paradict (https://github.com/pyrustic/paradict), my solution for streamable multi-format serialization. Although JSON, YAML, and TOML are all human-readable, they serve different purposes. For example, TOML is specifically designed for configuration files while JSON is used as a data interchange format. Sometimes an initiative to create a binary version of JSON arises and as far as I know, it ends with an unidirectional mapping of datatypes. There is no silver bullet, yet one coherent solution built from scratch…
