To wait for all downloads to complete with Puppeteer using request interception, you can use the request event to intercept all network requests made by the browser and track when they are finished. Finally, we close the browser instance.īy using the download event, we can wait for all downloads to complete with Puppeteer in a reliable and efficient way. We then navigate to the page that initiates the download and wait for all downloads to complete using the waitForDownload method. Let’s install Puppeteer with npmi i puppeteer, and implement our use case. Excellent That’s what we were looking for. If you read the docs, the first thing it says about Puppeteer is that you can use it to Generate screenshots and PDFs of pages’. We add a listener to the download event to log when a download is completed. It’s basically a browser which you can run from Node.js. We then set the download behavior for the page to allow downloads and specify the download path. In this code, we first create a new browser instance using Puppeteer and a new page. send ( 'tDownloadBehavior', ) await page. ) Īwait page.Const puppeteer = require ( 'puppeteer' ) const browser = await puppeteer. Specifies wether it allows downloading multiple files or notĪwait page._nd('tDownloadBehavior', My question is, is there a way to wait for a download to complete using Node+Puppeteer? I have tried using waitUntil: 'networkidle0 and networkidle2 but both seem to wait forever.Ĭode below: const path = require('path') Ĭonst browser = await puppeteer.launch() I have a script made using node.js and puppeteer which downloads a file from a button (which doesn't redirect to a url), so right now i'm using await await page.waitForTimeout(1000) to wait for the download to complete but it has a few flaws, such as:ĭepending on the connection, the download might take more than 1000ms to finish, as well as it might take less, which wouldn't make sense to wait more than what took to finish the download.
