Introduction

This repo allows you to log + track logs using sentry

Features

• Typescript compatible. Includes Type definitions

Installation

Bundling

This module is distributed in 3 formats

• lib.esm build dist/lib.esm/index.js in es6 format
• lib.cjs build dist/lib.cjs/index.js in es5 format
• umd build dist/loglevelSentry.umd.min.js in es5 format without polyfilling corejs minified

By default, the appropriate format is used for your specified usecase You can use a different format (if you know what you're doing) by referencing the correct file

The cjs build is not polyfilled with core-js. It is upto the user to polyfill based on the browserlist they target

Directly in Browser

CDN's serve the non-core-js polyfilled version by default. You can use a different

Usage

Add @toruslabs/loglevel-sentry to your project:

To use this module:

1. Install the package npm i @toruslabs/loglevel-sentry

2. Create your loglevel instance and install this plugin to enable Sentry:

import loglevel from "loglevel";
import * as Sentry from "@sentry/browser";
// Node.js: import * as Sentry from "@sentry/node";
import LoglevelSentryPlugin from "@toruslabs/loglevel-sentry";

logger = loglevel.getLogger("__LOGGER_NAME__");

const plugin = new LoglevelSentryPlugin(Sentry);
sentry.install(logger);

(Optional) You can replace loglevel with other logging library by using loglevel methodFactory API:

import loglevel from "loglevel";
import pino from "pino";
import * as Sentry from "@sentry/browser";
// Node.js: import * as Sentry from "@sentry/node";
import LoglevelSentryPlugin from "@toruslabs/loglevel-sentry";

const logger = loglevel.getLogger("__LOGGER_NAME__");
logger.methodFactory = (method, level, name) => {
  const alt = pino(name, level);
  return alt[method];
};

const sentry = new LoglevelSentryPlugin(Sentry);
sentry.install(logger);

Info

Is 100% compatible with loglevel API. Events/errors will be reported for all enabled log functions.

Best practices

Though it isn't compulsory, it is recommended to call log functions with following signatures:

• log.trace, log.debug, log.info, and log.warn: (msg: string, ...others: any[]).

• log.error: (err: Error, ...others: any[]).

If you always want to monitor a specific event regardless of configured log level, use the plugin API:

const sentry = new LoglevelSentryPlugin(Sentry);
sentry.install(logger);

sentry.trace("this", "message", "will always be reported.");

Requirements

• This package requires a peer dependency of @babel/runtime
• Node 20+
