Class: ResponseSync

Defined in: response-sync.ts:43

Synchronous Response wrapper

Provides synchronous body access methods (.text(), .json(), .arrayBuffer()) by storing the body separately in serializable format.

Constructors​

Constructor​

new ResponseSync(body?, init?): ResponseSync

Defined in: response-sync.ts:56

Create a ResponseSync

Parameters​

body?​

SerializableBody

Serializable body (string, ArrayBuffer, or plain object)

init?​

ResponseInit

Response options (status, headers, etc.)

Returns​

ResponseSync

Properties​

_response​

_response: Response

Defined in: response-sync.ts:45

Internal Response object (metadata only, no body stream)

body​

body: SerializableBody

Defined in: response-sync.ts:48

Serializable body (string, ArrayBuffer, or plain object)

Accessors​

headers​

Get Signature​

get headers(): Headers

Defined in: response-sync.ts:151

Response headers

Returns​

Headers

ok​

Get Signature​

get ok(): boolean

Defined in: response-sync.ts:156

Whether response is successful (status 200-299)

Returns​

boolean

redirected​

Get Signature​

get redirected(): boolean

Defined in: response-sync.ts:161

Whether response was redirected

Returns​

boolean

status​

Get Signature​

get status(): number

Defined in: response-sync.ts:141

HTTP status code

Returns​

number

statusText​

Get Signature​

get statusText(): string

Defined in: response-sync.ts:146

HTTP status text

Returns​

string

type​

Get Signature​

get type(): ResponseType

Defined in: response-sync.ts:166

Response type

Returns​

ResponseType

url​

Get Signature​

get url(): string

Defined in: response-sync.ts:171

Response URL

Returns​

string

Methods​

arrayBuffer()​

arrayBuffer(): ArrayBuffer

Defined in: response-sync.ts:107

Get body as ArrayBuffer (synchronous)

Returns​

ArrayBuffer

ArrayBuffer representation of body

blob()​

blob(): Blob

Defined in: response-sync.ts:125

Get body as Blob (synchronous)

Returns​

Blob

Blob containing body data

clone()​

clone(): ResponseSync

Defined in: response-sync.ts:182

Clone this ResponseSync

Returns​

ResponseSync

New ResponseSync with same properties

formData()​

formData(): never

Defined in: response-sync.ts:134

FormData not supported in sync mode

Returns​

never

Throws​

Always throws - use json() or text() instead

json()​

json(): any

Defined in: response-sync.ts:71

Get body as parsed JSON (synchronous)

Returns​

any

Parsed JSON object or null if no body

text()​

text(): string

Defined in: response-sync.ts:89

Get body as text string (synchronous)

Returns​

string

Text representation of body

toResponse()​

toResponse(): Response

Defined in: response-sync.ts:197

Convert to real Response object

Useful for returning from fetch() handlers or other APIs that expect a real Response.

Returns​

Response

Real Response object with body

fromResponse()​

static fromResponse(response): Promise<ResponseSync>

Defined in: response-sync.ts:226

Create a ResponseSync from a real Response object

Note: This is async because it needs to read the Response body stream. Use this when you have a real Response and need to convert it for serialization.

Parameters​

response​

Response

Real Response object

Returns​

Promise<ResponseSync>

Promise<ResponseSync>

Example​

const response = await fetch('https://api.example.com/data');
const syncResponse = await ResponseSync.fromResponse(response);
// Now can serialize syncResponse with structured-clone (sync!)
