Project mention: Framework Interoperable Component Libraries Using Lit Web Components. | dev.to | 2023-10-08

I've been very passionate about a project called react-jsonschema-form (github, editor). I personally hate writing forms, and love the idea of serializable components, schema, validation all in one. I've always wanted an alternative to this project that offered an alternative to react, and possibly the ability to render a schema form to static HTML (like ssg).
