How to extend log messages?

At a glance

The community member is asking if there are any plans to extend the Crawlee logger, and they provided some code to set the skipTime option, but it doesn't seem to work and they get a TypeError. Another community member responded that the issue is because utils is no longer exported from the apify package, so log is undefined. The solution is to import log and LoggerText directly from crawlee instead.

Are there any plans to extend Crawlee logger?
Ref: https://crawlee.dev/api/core/class/Logger

I found this to set the skipTime option

Plain Text

const Apify = require('apify');

const { utils: { log } } = Apify;

log.setOptions({
    logger: new log.LoggerText({ skipTime: false }),
});

but it doesn't seem to work. I got Uncaught TypeError TypeError: Cannot read properties of undefined (reading 'log')

My code:

Plain Text

import Apify from 'apify'
const { utils: { log } } = Apify;

log.setOptions({
    logger: new log.LoggerText({ skipTime: false }),
});

// https://crawlee.dev/api/playwright-crawler/class/PlaywrightCrawler
const crawler = new PlaywrightCrawler(
    launchContext: {
        launchOptions: {
            headless: true,
            stealth: true,
            viewport: { width:600, height:300 }
        },
    },
    async requestHandler({ request, page, enqueueLinks, log }) {
        const title = await page.title();
        log.info(`Titre: ${title} Url: ${request.loadedUrl}`);
    }

The reason is because utils is no longer exported from the apify package, therefore it is undefined. That's why you get the error of Cannot read 'log' of undefined. log doesn't exist on undefined.

Instead, you should import log from crawlee like this:

Plain Text

import { log, LoggerText } from 'crawlee';

log.setOptions({
    logger: new LoggerText({ skipTime: false }),
});
