Node.js se Browshot par website screenshot capture karne ke liye official browshot package install karein, API key se client banayein, phir Simple API se seedha image lein ya full API se screenshot status aur retrieval ko khud manage karein. Neeche dono CommonJS flows, key safety, capture options aur aam failure cases diye gaye hain.
Browshot Node.js setup ke liye kya chahiye?
- Node.js project aur npm.
- Browshot account se API key. Ise secret rakhein—source code ya public repository mein hard-code na karein.
- Target website ka URL aur Browshot instance. Full screenshot API mein
urlaurinstance_idzaroori hain; Browshot docs default free instance ko ID12batati hain.
Official Node.js library page installation ke liye npm i browshot aur CommonJS ke liye require('browshot') dikhati hai. Neeche ke examples isi documented style ka istemal karte hain; reviewed documentation native ES module support establish nahi karti. Browshot Node.js library guide
Package install karke Simple API se screenshot lein
Simple API tab chunen jab ek request mein screenshot mangwana aur image file save karna ho. Browshot is flow ko real-time screenshot ek request mein lautane wala batata hai. API documentation ke mutabik yeh complete API se aasaan, lekin dheema hai.
- Project directory mein
npm i browshotchalayein. - API key ko environment variable
BROWSHOT_API_KEYmein set karein. - Client banakar
client.simpleko URL aur instance ID dein; result code200ho tabhi image data file mein likhein.
CommonJS file, jaise capture.js:
const Browshot = require('browshot');
const fs = require('node:fs');
const apiKey = process.env.BROWSHOT_API_KEY;
if (!apiKey) {
throw new Error('Set BROWSHOT_API_KEY before running this script.');
}
const client = new Browshot(apiKey);
const url = 'https://example.com';
const instanceId = 12;
client.simple(url, { instance_id: instanceId }, (err, result) => {
if (err) {
console.error('Browshot request failed:', err);
process.exitCode = 1;
return;
}
if (!result || result.code !== 200 || !result.data) {
console.error('Screenshot was not returned successfully:', result);
process.exitCode = 1;
return;
}
fs.writeFileSync('screenshot.png', result.data);
console.log('Saved screenshot.png');
});Run it with BROWSHOT_API_KEY=your_key node capture.js on macOS/Linux. In PowerShell, set the variable first with $env:BROWSHOT_API_KEY="your_key", then run node capture.js. The library example checks for code 200 and writes result.data as PNG; consult Browshot’s current library docs if its callback or result shape differs in your installed package version.

- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Use the full API when you need status and retrieval control
The full flow separates screenshot creation from image retrieval. Create a screenshot, inspect its status, wait or poll if it is in_process, then retrieve the image once finished. If status is error, surface the reported error rather than trying to save an incomplete image. Browshot’s docs describe these statuses but library method signatures and response shapes should be followed from its current documentation.
- Call the library’s
screenshotCreateoperation with the target URL and requiredinstance_id. - Read the returned screenshot record and status.
- If status is
in_process, wait and check again; avoid a tight polling loop. - When status is
finished, retrieve the screenshot image using the library’s image retrieval operation and save its returned data. - If status is
error, report the associated error information to the caller or logs.
Use this route when your application needs explicit control over completion and image retrieval. The Simple API is less orchestration for a one-off capture; the complete API is the documented choice when managing screenshot state matters. Browshot API documentation
Choose capture size and request options
Browshot’s full screenshot endpoint documents these options. Availability of advanced capabilities can depend on the selected instance, so confirm support for the instance you use.

| Option | What it controls |
|---|---|
size |
screen requests the screen/viewport capture; page requests a page-sized capture. |
| Cache lifetime | Controls how long a cached result may be reused; useful when repeat captures need not be freshly rendered. |
| Delay after page load | Waits after load before capture, which can help pages that render content shortly afterward. |
| Maximum wait | Sets the maximum wait period for the capture request. |
| Custom headers | Sends headers with the page request, where supported. |
| JavaScript and CSS-selector targeting | Run documented capture behavior or target page elements where supported by the instance. |
Automation documentation also describes steps such as clicking, typing, waiting, navigating and capturing during a workflow. Browshot’s pre-capture JavaScript page says the script must finish within the configured delay, with a maximum of 10 seconds on that page; do not assume every instance supports every advanced feature. Browshot automation documentation · Browshot pre-capture JavaScript documentation
Quota, credits and operational considerations
Browshot’s API documentation states that its default free instance is instance 12 and allows 100 free screenshots per month. The same documentation says private and shared instances require a positive balance. These are vendor-published terms and may change, so check the current account terms before relying on a quota or running a workflow that can consume credits. Browshot’s Node.js examples also warn that running them can cost credits. Browshot API documentation
- For repeat captures where freshness is not essential, consider an appropriate cache lifetime to avoid unnecessary recaptures.
- Use a bounded delay and maximum wait rather than waiting indefinitely; extra waiting can affect how long a capture takes.
- Handle network/API errors and non-finished screenshot states before writing data to disk.
Troubleshooting common Browshot screenshot problems
Missing API key or authentication failure
Confirm BROWSHOT_API_KEY is set in the shell running Node.js and that the key is valid. Do not commit the key or print it in logs.

Invalid instance or insufficient balance
Check that the full API request includes a valid instance_id. If using a private or shared instance, verify the account has a positive balance; the default free instance and its stated monthly allowance are subject to Browshot’s current terms.
The screenshot is still in process
Do not treat an in_process record as an image. Wait and check status again, with a sensible interval and an overall timeout; retrieve image data only after completion.

Saved file is empty or invalid
Write image data only after confirming a successful result. In the Simple example, that means checking for code 200 and non-empty result.data; in the full flow, retrieve data only after finished.
Page content is missing from the capture
Some pages render after initial load. Where the selected instance supports it, adjust the documented delay-after-load setting or use a supported selector/automation workflow. Avoid assuming a script or interaction feature is available on every instance.
