Core API

Use esc-json-form-core for framework-agnostic control.

import { createJsonFormStore } from "esc-json-form-core";

const store = createJsonFormStore({ name: "test", age: 2 });

store.getValue();
store.setValue({ name: "new", age: 3 });

store.getAtPath(["age"]);
store.setAtPath(["age"], 10);

store.setTypeAtPath(["age"], "string");

store.addArrayItem(["items"]);
store.removeArrayItem(["items"], 0);
store.addObjectKey(["profile"], "bio", "string");

store.validate();

Schema Is Optional

Validation only runs when you set a schema:

store.setSchema({
  type: "object",
  properties: {
    age: { type: "number", rules: { min: 1 } },
  },
});

Supported Value Types

Core JsonValueType supports:

• string
• number
• boolean
• null
• object
• array

Renderer-specific editor mode:

• React/Angular add a textarea UI mode for strings.

Date values:

• date is not a separate core type.
• Store dates as string values (for example, ISO format).
