Re-using the crawler, instead initializing after each url?

// worker.ts
import { Worker } from 'bullmq';
import { CheerioCrawler, ProxyConfiguration } from 'crawlee';
import Redis from 'ioredis';
import { router } from './router';
import dotenv from 'dotenv';
dotenv.config();

console.log("REDIS_URL_JOB_QUEUE", process.env.REDIS_URL_JOB_QUEUE)
const connection = new Redis(process.env.REDIS_URL_JOB_QUEUE || '', {
    maxRetriesPerRequest: null
}); // Connect to a local Redis instance

const proxy = process.env?.PROXY_URL || '';
console.log('proxy', proxy)

const proxyConfiguration = new ProxyConfiguration({
    proxyUrls: [proxy],
});

const crawler = new CheerioCrawler({
    proxyConfiguration,
    requestHandler: router,
});

const scraperWorker = new Worker(
    'scraper',
    async (job) => {
        const url: string = job.data.url;
        
        try {
            // await crawler.addRequests([url]);
            await crawler.run([
                {
                    label: 'PRODUCT',
                    url
                },
            ]);

            // If everything went well, return a result
            return { result: 'success' };
        } catch (error) {
            // If something went wrong, throw an error
            console.error(`Scrape of ${url} failed with error ${error.message}`);
            throw error;
        }
    },
    {
        connection, limiter: {
            max: 2,    // Max number of jobs to handle
            duration: 5000 // per duration value in milliseconds (60,000ms = 1 minute)
        }
    }
);

scraperWorker.on('completed', (job, result) => {
    console.log(`Job ${job.id} completed with result ${result.result}`);
});

scraperWorker.on('failed', (job, err) => {
    if (!job) return console.log('Job not found');
    console.log(`Job ${job.id} failed with error ${err.message}`);
});
