State

State holders for JsonViewerCMP and JsonEditorCMP. Both expose observable Compose state properties — no callbacks needed.

JsonViewerState

Creating State

@OptIn(ExperimentalJsonCmpApi::class)
@Composable
fun MyScreen() {
    val state = rememberJsonViewerState(json = """{"key": "value"}""")
}

The viewer responds to changes in the json parameter — passing a new value triggers a re-parse and updates the display.

Properties

Property	Type	Description
json	String	Current raw JSON text being displayed
parsedJson	JsonNode?	Parsed JSON tree, or null if invalid
error	JsonError?	Parse error, or null if valid

---

JsonEditorState

Creating State

@OptIn(ExperimentalJsonCmpApi::class)
@Composable
fun MyScreen() {
    val state = rememberJsonEditorState(initialJson = """{"key": "value"}""")
}

initialJson is used only once to seed the editor. The editor owns its own text state internally. To load entirely new content, wrap the composable in a key(documentId) block.

Properties

Property	Type	Description
json	String	Current raw JSON text in the editor
parsedJson	JsonNode?	Parsed JSON tree, or null if invalid
error	JsonError?	Parse error, or null if valid
