Puppeteer ka fullPage: true poore page ka screenshot leta hai, lekin apne aap scroll karke lazy ya infinite-scroll content load karne ki guarantee nahi deta. Pehle page ko bounded steps mein scroll karein, har step ke baad website ke actual content ya end marker ka intezar karein, phir screenshot lein.
Scrolling aur screenshot alag kaam hain
page.screenshot() screenshot capture karta hai; fullPage: true capture area ko poore page tak badhata hai. Scroll-triggered content mangwane ke liye page par waqai scroll action karna zaroori hai. Isliye sequence hai: navigate, target content ke liye wait, scroll aur load ki jaanch, phir screenshot. Puppeteer ke screenshot guide aur API docs mein in alag capabilities ka varnan hai: screenshot guide, screenshot API aur page.evaluate().
Kaunsa wait chunna chahiye?
| Wait strategy | Kab upyogi hai | Seema |
|---|---|---|
waitUntil: 'networkidle2' |
Initial navigation ke dauran network ke settle hone ka intezar. Puppeteer ke official guide mein iska example diya gaya hai. | Yeh scroll ke baad zaroori content aa jaane ka saboot nahi hai. |
waitForSelector() |
Jab loaded item ya target element ka selector maloom ho. | Selector target site ke markup se mel khana chahiye. |
waitForFunction() |
Jab item count, page state, ya kisi aur JavaScript condition se readiness pehchani ja sakti ho. | Predicate ko site ke behavior ke mutabik banana padta hai. |
In waits aur evaluation methods ke options ke liye waitForSelector() aur waitForFunction() dekhein. Fixed delay ko readiness test na samjhein: woh sirf bounded pause hai, aur har site par content usi samay mein load ho, zaroori nahi.

Scroll-triggered content ke liye runnable Node.js pattern
Yeh adaptable implementation pattern hai, har site par tested ya universal stopping algorithm nahi. .content-item ko site ke asli item selector se badlein. Agar site ke items pehle se maujood container mein add karti hai, item count ya last-item marker check karein; sirf page height par nirbhar na rahein.

- Selector:
.content-itemke badle us element ka selector dein jo waqai load hone wale content ko darshata hai. Initial wait mein pehla item milna sirf itna batata hai ki kuch content aaya; poori feed load hui, yeh nahi. - Completion condition: Infinite scroll ke liye target item count, known last item, end marker, ya site-specific state ko check karein.
scrollHeighttabhi useful signal hai jab site naye content par document height badhati ho. - Boundaries:
maxStepsaur har wait ka timeout rakhein. Infinite feed ka ant ho hi, yeh zaroori nahi; bounded loop script ko anishchit samay tak chalne se rokta hai. - Scrolling container: Agar page ke bajay koi andar ka panel scroll hota hai,
window.scrollBy()us panel ko nahi scroll karega. Us container ko target karke uska scroll position badlein aur usi container ke content/end condition ko check karein. - Screenshot ka daayra: Poore document ke liye
fullPage: truerakhein. Sirf ek element capture karna ho toElementHandle.screenshot()use kiya ja sakta hai; Puppeteer docs ke mutabik hidden element screenshot se pehle view mein scroll kiya jata hai. ElementHandle.screenshot().
ScreenshotNeo se browser setup chhodein
Agar aap apna Puppeteer browser aur scroll workflow chalane ke bajay API se screenshot lena chahte hain, ScreenshotNeo ek website screenshot API hai. Iska ek GET request PNG, JPEG, WebP ya PDF la sakta hai. Dhyan rahe: neeche diya gaya ek-call example URL ka screenshot maangta hai; ismein Puppeteer jaisa custom scroll-and-wait loop nahi hai, isliye scroll-triggered feed ka poora load hona maan kar na chalein.

Aam dikkat aur unke hal
- Screenshot mein sirf pehla viewport hai: Screenshot options mein
fullPage: truecheck karein. - Full-page image ka neeche ka hissa khaali ya adhura hai: Screenshot se pehle scroll actions aur content-specific waits chalayein. Full-page capture loading trigger nahi karta.
- Wait timeout hota hai: Selector ya predicate ko verify karein ki woh target page par waqai maujood hai. Explicit timeout rakhein; agar site background requests chalaati rehti hai, network idle ko akela completion signal na banayein.
- Scroll ke baad bhi content nahi aata: Dekhein ki page window scroll karta hai ya nested container; phir usi jagah scroll karein. Height-based observation tab chunein jab site naye content par document height badhati ho.
- Loop bahut jaldi rukta hai: End condition ko site ke real last-item marker ya loaded item count se jodein. Height na badhna apne aap mein har implementation par feed ke ant ka pramaan nahi.
