# Function: stringifyFrameGraphSnapshot()

> **stringifyFrameGraphSnapshot**(`snapshot`, `options?`): `string`

Defined in: [packages/snapshot/src/codec.ts:245](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/snapshot/src/codec.ts#L245)

Validates and serializes a canonical Snapshot 1.2 document.

## Parameters

### snapshot

[`FrameGraphSnapshotV1`](/zenfg/docs/api/snapshot/root/type-aliases/FrameGraphSnapshotV1.md)

Producer-owned snapshot to validate before serialization.

### options?

[`FrameGraphSnapshotStringifyOptions`](/zenfg/docs/api/snapshot/root/type-aliases/FrameGraphSnapshotStringifyOptions.md) = `{}`

Formatting options. Omitted options produce compact JSON.

## Returns

`string`

Canonical JSON text without mutating `snapshot`.

## Remarks

The input is cloned through own data-property descriptors before
validation and serialization, so getters and `toJSON` hooks are never
invoked. Extension object/array nesting is limited by
[FRAME\_GRAPH\_SNAPSHOT\_MAX\_EXTENSION\_DEPTH](/zenfg/docs/api/snapshot/format/variables/FRAME_GRAPH_SNAPSHOT_MAX_EXTENSION_DEPTH.md).

## Throws

[FrameGraphSnapshotValidationError](/zenfg/docs/api/snapshot/root/classes/FrameGraphSnapshotValidationError.md) when JSON-safety or
semantic validation fails.
