Introduction

This is a simple log library. It is meant to be used on projects with Docker / containerized applications with Deno or Node.

Nothing special really just a simple log...

So why create another log library? Well I don't need more than what is included... more information just wastes more CPU cycles ... If you need more... use another library.

Usage

This is an example of usage

import { JsonLog } from "@danielfroz/slog";

const log = new JsonLog();
log.info({ msg: `this is a valid log line` });

You may want to add prefix on all log lines from a component... As such use the following

const id = crypto.randomUUID();
const log = new JsonLog({
  level: "INFO",
  init: { handler: "component", id },
});
log.info({ msg: `this is another line` });

Output produced shall include the information passed.
