capture-website-core
Advanced tools
Forked from capture-website.
capture-website uses puppeteer and always downloads Chromium when install, which takes time and disk space.
capture-website-core uses puppeteer-core and avoids downloading Chromium as long as compatible browsers found in your system:
Capture screenshots of websites
It uses Puppeteer (Chrome) under the hood.
See capture-website-cli for the command-line tool.
$ npm install capture-website
Note to Linux users: If you get a sandbox-related error, you need to enable system sandboxing.

Type: string
Values: Devices (Use the name property)
Make it look like the screenshot was taken on the specified device.
This overrides the width, height, scaleFactor, and userAgent options.

emulateDevice: 'iPhone X'
});
Type: boolean

Type: string
Capture the DOM element matching the given CSS selector. It will wait for the element to appear in the page and to be visible. It times out after options.timeout seconds. Any actions performed as part of options.beforeScreenshot occur before this.
Type: string[]

Can be useful for cleaning up the page.
This sets visibility: hidden on the matched elements.
import captureWebsite from 'capture-website';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
hideElements: [
'#sidebar',
'img.ad'
]
});

import captureWebsite from 'capture-website';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
modules: [
'https://sindresorhus.com/remote-file.js',
'local-file.js',
`
document.body.style.backgroundColor = 'red';
`
]
});
Type: string[]
Same as the modules option, but instead injects the code as <script> instead of <script type="module">. Prefer the modules option whenever possible.
Type: string[]
Inject CSS styles into the page.
Accepts an array of inline code, absolute URLs, and local file paths (must have a .css extension).
import captureWebsite from 'capture-website';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
styles: [
'https://sindresorhus.com/remote-file.css',
'local-file.css',
`
body {
background-color: red;
}
`
]
});
Type: object
Default: {}
Set custom HTTP headers.
import captureWebsite from 'capture-website';

'x-powered-by': 'https://github.com/sindresorhus/capture-website'
}
});
Type: string
Set a custom user agent.
Type: Array<string | object>
Set cookies in browser string format or object format.
Tip: Go to the website you want a cookie for and copy-paste it from DevTools.
import captureWebsite from 'capture-website';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
cookies: [
// This format is useful for when you copy it from the browser
'id=unicorn; Expires=Wed, 21 Oct 2018 07:28:00 GMT;',
// This format is useful for when you have to manually create a cookie
{
name: 'id',

}
]
});
Type: object
Credentials for HTTP authentication.
Type: string
Type: string
Type: Function
The specified function is called right before the screenshot is captured, as well as before any bounding rectangle is calculated as part of options.element. It receives the Puppeteer Page instance as the first argument and the browser instance as the second argument. This gives you a lot of power to do custom stuff. The function can be async.
Note: Make sure to not call page.close() or browser.close().
import captureWebsite from 'capture-website';
import checkSomething from './check-something.js';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
beforeScreenshot: async (page, browser) => {
await checkSomething();
await page.click('#activate-button');
await page.waitForSelector('.finished');
}
});
Type: boolean
Default: false
Show the browser window so you can see what it's doing, redirect page console output to the terminal, and slow down each Puppeteer operation.
Note: This overrides launchOptions with {headless: false, slowMo: 100}.
Type: boolean
Default: false
Emulate preference of dark color scheme (prefers-color-scheme).
Type: object | number
Default: 0
Inset the bounding box of the screenshot.
Accepts an object {top?: number; right?: number; bottom?: number; left?: number} or a number as a shorthand for all directions.
Positive values, for example inset: 10, will decrease the size of the screenshot.
Negative values, for example inset: {left: -10}, will increase the size of the screenshot.
Note: This option is ignored if the fullPage option is set to true. Can be combined with the element option.
Note: When the width or height of the screenshot is equal to 0 an error is thrown.
Example: Include 10 pixels around the element.
import captureWebsite from 'capture-website';
await captureWebsite.file('index.html', 'screenshot.png', {
element: '.logo',
inset: -10
});
Example: Ignore 15 pixels from the top of the viewport.
import captureWebsite from 'capture-website';
await captureWebsite.file('index.html', 'screenshot.png', {
inset: {
top: 15
}
});
Type: object
Default: {}
Options passed to puppeteer.launch().
Note: Some of the launch options are overridden by the debug option.
Type: boolean
Default: false
Overwrite the destination file if it exists instead of throwing an error.
This option applies only to captureWebsite.file().
Type: string | Function
Default: undefined
Inject a function to be executed prior to navigation.
This can be useful for altering the JavaScript environment. For example, you could define a global method on the window, overwrite navigator.languages to change the language presented by the browser, or mock Math.random to return a fixed value.
Type: object
Define the screenshot's position and size (clipping region).
The position can be specified through x and y coordinates which starts from the top-left.
This can be useful when you only need a part of the page.
You can also consider using element option when you have a CSS selector.
Note that clip is mutually exclusive with the element and fullPage options.
numbernumbernumbernumberFor example, define the screenshot's width and height to 400 at position (0, 0):
import captureWebsite from 'capture-website';
await captureWebsite.file('https://sindresorhus.com', 'screenshot.png', {
clip: {
x: 0,
y: 0,
width: 400,
height: 400
}
});
Type: string[]
Devices supported by the emulateDevice option.
import captureWebsite from 'capture-website';
const options = {
width: 1920,
height: 1000
};
const items = [
['https://sindresorhus.com', 'sindresorhus'],
['https://github.com', 'github'],
// …
];
await Promise.all(items.map(([url, filename]) => {
return captureWebsite.file(url, `${filename}.png`, options);
}));
Check out filenamify-url if you need to create a filename from the URL.
If you get an error like No usable sandbox! or Running as root without --no-sandbox is not supported, you need to properly set up sandboxing on your Linux instance.
Alternatively, if you completely trust the content, you can disable sandboxing (strongly discouraged):
import captureWebsite from 'capture-website';
await captureWebsite.file('…', '…', {
launchOptions: {
args: [
'--no-sandbox',
'--disable-setuid-sandbox'
]
}
});
The biggest difference is that Pageres supports capturing multiple screenshots in a single call and it automatically generates the filenames and writes the files. Also, when projects are popular and mature, like Pageres, it becomes harder to make drastic changes. There are many things I would change in Pageres today, but I don't want to risk making lots of breaking changes for such a large userbase before I know whether it will work out or not. So this package is a rethink of how I would have made Pageres had I started it today. I plan to bring some things back to Pageres over time.
