The Challenge
Building a no-code mobile app builder means solving a meta-problem: how do you let users *describe* an app that your system then *renders*?
Schema-Driven UI
The core idea: every screen is a JSON schema that our renderer interprets at runtime.
{
"screen": "ProductList",
"components": [
{
"type": "List",
"dataSource": "products",
"itemTemplate": {
"type": "Card",
"title": "{{item.name}}",
"subtitle": "{{item.price}}"
}
}
]
}
Dynamic Rendering in React Native
function DynamicRenderer({ schema }: { schema: Component }) {
switch (schema.type) {
case "List":
return <DynamicList schema={schema} />;
case "Card":
return <DynamicCard schema={schema} />;
default:
return null;
}
}
