I have a loop which contains an puppeteer function. The problem is that the loop is doing all puppeteer at the same time.
I've tried this:
import puppeteer from "puppeteer"
(async function(){
for(let i = 0; i < 3; i++){
await launchPup().then(() => {
});
}
})()
async function launchPup() {
puppeteer.launch({headless: false}).then(async browser => {
await browser.newPage()
await browser.close()
})
}
Could you tell me what I'm doing wrong and how can fix this?
Its is an async function, you have to keep a look out at the created browser.
something like this should help you.
var totalOpenedbrowser = 0;
var minBrowser = 2;
const wait = () => new Promise((resolve) => setTimeout(resolve, 200))
(async function() {
for (let i = 0; i < 3; i++) {
await launchPup().then(() => {});
}
})()
async function launchPup() {
while (totalOpenedbrowser > = minBrowser)
await wait(); // wait until there is a free slott
totalOpenedbrowser++;
puppeteer.launch({
headless: false
}).then(async browser => {
await browser.newPage()
await browser.close()
totalOpenedbrowser--;
})
}Have a look at the library I build, it will solve your issue https://www.npmjs.com/package/puppeteer-express
