Ends the response process without higher-level body formatting.

Since Express 4 (Node http) Spec ↗

Syntax

res.end([data][, encoding])

Parameters

Name	Type	Required	Description
`data`	`string \| Buffer`	No	Optional final chunk to write before ending.
`encoding`	`string`	No	Encoding for string data.

Returns

Response — The response object.

Examples

app.get('/ping', (req, res) => {
  res.status(204).end();
});

Output

(204 No Content, empty body)

app.get('/stream', (req, res) => {
  res.write('chunk 1\n');
  res.write('chunk 2\n');
  res.end();
});

Output

chunk 1
chunk 2

Notes

This is the low-level Node method. Prefer `res.send`/`res.json` for normal responses since they set headers for you. Use `end()` to finish an empty or manually-streamed response. Must be called exactly once.
