@probot/pino

formats pino logs and sends errors to Sentry

About

@probot/pino is currently built into probot, you don't need to manually pipe probot's logs into it. It will be easy to move it out of probot in future though, and give people a simple way to recover the logging behavior if they wish, or to replace it with another pino transport

CLI Usage

node my-script.js | pino-probot

You can test the environment variables by setting them inline

node my-script.js | LOG_FORMAT=json pino-probot

Programmatic usage

@probot/pino exports a getTransformStream() method which can be passed as 2nd argument to pino()

import pino from "pino";
import { getTransformStream } from "@probot/pino";

const log = pino(
  {
    name: "probot",
  },
  getTransformStream()
);

This won't log anything to stdout though. In order to pass the formatted logs back to stdout, do the following

import pino from "pino";
import { getTransformStream } from "@probot/pino";

const transform = getTransformStream();
transform.pipe(pino.destination(1));
const log = pino(
  {
    name: "probot",
  },
  transform
);

With custom options:

const transform = getTransformStream({
  logFormat: "json",
  logLevelInString: true,
  sentryDsn: "http://[e-mail]/1234",
});

Options

The pino-probot binary can be configured using environment variables, while the getTransformStream() accepts an object with according keys

Environment Varibale	Option	Description
LOG_FORMAT	logFormat	Set to pretty or json. When set to pretty, logs are formatted for human readability. Setting to json logs using JSON objects. Defaults to pretty
LOG_LEVEL_IN_STRING	logLevelInString	By default, when using the json format, the level printed in the log records is an int (10, 20, ..). This option tells the logger to print level as a string: {"level": "info"}. Default false
SENTRY_DSN	sentryDsn	Set to a Sentry DSN to report all errors thrown by your app. (Example: https://[e-mail]/12345)
