Not sure about your specific code and whether your click is "happening" on the right element to trigger navigation, but in general if you want to make sure you catch an expected navigation event, create the waitForNavigation promise (but do not await it yet) BEFORE you trigger the navigation, i.e. before the click, not after.

Networkidle0 Consider navigation to be finished when there are no more than 0 network connections for at least 500 ms. Networkidle2. Range pdf page. In puppeteer create pdf is similar to taking a screenshot with the fullPage parameter, i.e. the resulting pdf may contain more than one page (the number depends on the page size of the site). To limit the number of pages or specify specific pages, you can use the pageRanges parameter, for example, display only the first page 1, the range 1-5, or.

We are using the Nodes native path to specify our download path in line 2 and 3. On line 15 we are using the Page.setDownloadBehavior property of Puppeteer to tie up the path to Chrome browser.

Instead of simulating clicks we are going to find. waitUntil load window.onload, domcontentloaded Domcontentloaded networkidle0 500ms (request), networkidle2 500ms 2 (request), networkidle0> networkidle2>load>domcontentloaded networkidle0,2s.

waitUntil DOM.. During the automation of multiple tasks on my job and personal projects, i decided to move on Puppeteer instead of the old school PhantomJS. One of the most usual problems with pages that contain a lot of content, because of the ads, images etc. is the load time, an exception is thrown (specifically the TimeoutError) after a page takes more than 30000ms (30 seconds) to load totally. page.waitForSelector(".company-listing"); awaitwaitUntil "networkidle2" xpath). page.goto waitForSelectorwaitUntil "networkidle2". waitUntil load. The load option fires when the whole page has loaded, including all dependent resources such as stylesheets, fonts and images. It is equivalent to waiting for the load event on the window window.addEventListener("load", (event) > console.log("page is fully loaded");); Let's change the example above to wait for the load event.

Puppeteer is a Node library which provides a high-level API to control Chromium or Chrome over the DevTools Protocol. The Puppeteer API is hierarchical and mirrors the browser structure. NOTE On the following diagram, faded entities are not currently represented in Puppeteer. Puppeteer communicates with the browser using DevTools Protocol. There are few more browsers with headless mode supported, for example, Splash, Chromium, etc. Splash is aimed at Python programmers. In this Puppeteer tutorial, we will be focusing on Chromium. Chromium is an open-source web browser made by Google. Note that Chromium and Chrome are two different browsers. Chromium is an open-source project.

Explicit wait in puppeteer Explicit wait or static wait is used to wait for a fixed or static time frame. for example, I set explicit wait like 50 sec. it means it will wait 50 sec before executing the next line of code. page.waitFor (time in ms) function is used to perform explicit wait in puppeteer. await page.waitFor(50000);. 2 networkidle0 0500 networkidle2 2500 (2) URLDOM URL.

With Puppeteer, we only need a few lines of code to convert web pages into PDF. First, create a browser instance using Puppeteers launch function. const browser await puppeteer.launch(); Then, we create a new page instance and visit the given page URL using Puppeteer. Puppeteer has a function called waitUntil where you can pass in several options. These options change the behavior of how and when it will complete the rendering of your page, and return the results. Options offered by waitUntil are load When this event is fired navigation will be completed.

Difference between networkidle0 and networkidle2 With options, Puppeteer waits for the network idle. Use networkidle0 for sites that loaded once and then don&x27;t send requests. An example is a SPA without any background activities. While networkidle2 is suitable for applications with open connections and sends requests after the page is loaded.
