Requires the broader Crawlab platform to be running since this is a plug-in module, not a standalone tool.

Wtf does this do

The crawlab-log project is a logging tool built for Crawlab, which is a web crawling management platform. In plain terms, it helps developers and data teams keep track of what their web scrapers are doing by collecting and organizing the messages those scrapers generate as they run. The code is written in Go, a programming language known for being fast and efficient. When a web crawler built on the Crawlab platform runs, it produces a stream of status updates, warnings, and error messages. This module captures that output so it can be stored, searched, or reviewed later. Think of it as the system's diary, recording every step the crawler takes so that if something goes wrong, someone can look back at the log and figure out what happened. The people who would use this are developers or data engineers running Crawlab to manage multiple web scraping tasks at once. For example, if a startup is scraping product prices from dozens of competitor websites every hour, they need a way to spot when a scraper fails because a site changed its layout. Without logging, a broken scraper might silently stop collecting data. With this module, the team gets a record they can check to see exactly when and why the failure occurred. The README doesn't go into much detail about specific features or configuration, so it's hard to say exactly how the logging is structured or what storage backends it supports. What's clear is that this is a narrowly focused utility designed to plug into the broader Crawlab ecosystem rather than stand on its own as a general-purpose logging solution.

Yoink these prompts

Prompt 1
I'm using the Crawlab platform to manage web scraping tasks. How do I integrate the crawlab-log Go module into my crawler so its output is captured for later review?
Prompt 2
Help me set up a Go-based web scraper on Crawlab that sends its status messages, warnings, and errors to crawlab-log so I can search through them after each run.
Prompt 3
Show me how to use crawlab-log to collect and organize log output from multiple Crawlab scrapers running simultaneously, so I can identify which scraper failed and why.
Prompt 4
I have a Crawlab scraper that silently stops collecting data when a competitor site changes its layout. How can I use crawlab-log to capture error messages that tell me exactly when the failure happened?
