Bundling

This module is distributed in 4 formats

  • esm build dist/loglevelSentry.esm.js in es6 format
  • commonjs build dist/loglevelSentry.cjs.js in es5 format
  • umd build dist/loglevelSentry.umd.min.js in es5 format without polyfilling corejs minified
  • node build dist/loglevelSentry-node.js in es5 format

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 12+
