e.g. The option batchSize as an env var would be PINO_HTTP_SEND_BATCH_SIZE.

URL

Example

$ node . | pino-http-send --url=http://localhost:8080

You can also do https...

$ node . | pino-http-send --url=https://myserver.com:8080

Body Type

• ndjson - New-line delimited JSON. See ndjson
• json - Standard JSON sending of data. Logs are sent in the format of

  {
    "logs": [...logs]
  }

Auth

Currently only basic auth is implemented for the CLI usage. For header usage, you can see the API usage.

API

You can also use this module as a pino destination.

This will use the same batching function like the CLI usage. If the batch length is not reached within a certain time (timeout), it will auto "flush".

createWriteStream

The options passed to this follow the same values as the CLI defined above.

Property	Type	Required/Default
url	string	REQUIRED
log	boolean	false
silent	boolean	false
method	string	"POST"
bodyType	string	"json"
username	string
password	string
headers	Record<string,string>
batchSize	number	10
retries	number	5
interval	number	1000
timeout	number	5000
config	string

import { createWriteStream } from 'pino-http-send';

const stream = createWriteStream({
  url: 'http://localhost:8080',
});

const logger = pino(
  {
    level: 'info',
  },
  stream,
);

logger.info('test log!');
