Environment Variables

All options can be defined in the environment and are prefixed with PINO_HTTP_SEND_. All camel-cased options are parsed with delimiters of _.

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!');
