JSON Forms
What JSON Forms is
JSON Forms is a free, MIT-licensed framework for building form-based web interfaces embedded within applications. It lets people enter, modify, and view data through forms defined with a data JSON Schema and a UI Schema that describes how those forms appear. Data binding, input validation, and rule-based visibility are built in. The framework has bindings for React, Angular, and Vue, with renderer options including React Material and vanilla, Angular Material, and Vue vanilla and Vuetify sets. Developers can add or replace renderers, or use the core package to build bindings for another application framework. Validation uses AJV and can be customized by passing a custom AJV instance to the standalone component. The project lists version 3.8.0, which adds support for Angular 22. Its Vue integration is in preview, and the Vuetify renderer set is also marked preview with known bugs. Community support is free through a public channel for basic topics, with longer response times. Professional support includes guaranteed response time, detailed answers, code examples, advanced topics, a private channel under NDA, and feature prioritization.
