Chromium Binary for AWS Lambda and Google Cloud Functions
npm install chrome-aws-lambda --save-prod
This will ship with appropriate binary for the latest stable release of puppeteer
(usually updated within a few days).
You will also need to install the corresponding version of puppeteer
(or puppeteer-core
):
npm install puppeteer-core --save-prod
If you wish to install an older version of Chromium, take a look at Versioning.
This package works with the nodejs8.10
, nodejs10.x
and nodejs12.x
AWS Lambda runtimes out of the box.
const chromium = require('chrome-aws-lambda');
exports.handler = async (event, context, callback) => {
let result = null;
let browser = null;
try {
browser = await chromium.puppeteer.launch({
args: chromium.args,
defaultViewport: chromium.defaultViewport,
executablePath: await chromium.executablePath,
headless: chromium.headless,
ignoreHTTPSErrors: true,
});
let page = await browser.newPage();
await page.goto(event.url || 'https://example.com');
result = await page.title();
} catch (error) {
return callback(error);
} finally {
if (browser !== null) {
await browser.close();
}
}
return callback(null, result);
};
You should allocate at least 512 MB of RAM to your Lambda, however 1600 MB (or more) is recommended.
Please refer to the Local Development Wiki page for instructions and troubleshooting.
Method / Property | Returns | Description |
---|---|---|
font(url) |
{?Promise<string>} |
Downloads a custom font and returns its basename. |
args |
{!Array<string>} |
Provides a list of recommended additional Chromium flags. |
defaultViewport |
{!Object} |
Returns more sensible default viewport settings. |
executablePath |
{?Promise<string>} |
Returns the path where the Chromium binary was extracted. |
headless |
{!boolean} |
Returns true if we are running on AWS Lambda or GCF. |
puppeteer |
{!Object} |
Overloads puppeteer and returns the resolved package. |
Since version 1.12.2
, the font()
method will download additional fonts and make them discoverable.
To use it, simply pass a URL or local file path to a custom font face before launching Chromium, e.g.:
await chromium.font('https://raw.githack.com/googlei18n/noto-emoji/master/fonts/NotoColorEmoji.ttf');
The above font is needed if you want to render emojis.
Fonts with the same basename will only be downloaded if they are not already cached.
On non-serverless environments, the
font()
method is a no-op to avoid polluting the user space.
It's recommended that you use a CDN, like raw.githack.com or gitcdn.xyz.
As of version 3.0.4
, the font()
method will also work with local file paths and HTTP URLs.
Since version 1.7.0
, it's also possible to overload puppeteer
/ puppeteer-core
API with useful methods:
Frame
count(selector)
exists(selector)
fill(form, data, heuristic = 'name')
number(selector, decimal = null, index = null, property = 'textContent')
selectByLabel(selector, ...values)
string(selector, property = 'textContent')
waitUntilVisible(selector, timeout = null)
waitWhileVisible(selector, timeout = null)
Page
clickAndWaitForNavigation(selector, options = null)
count(selector)
exists(selector)
fill(form, data, heuristic = 'name')
go(url, options = null)
number(selector, decimal = null, index = null, property = 'textContent')
selectByLabel(selector, ...values)
string(selector, property = 'textContent')
waitUntilVisible(selector, timeout = null)
waitWhileVisible(selector, timeout = null)
Since version 5.0.0
the number of overloads are further augmented:
Browser
newPage(...hooks)
Page
allow(...resources)
block(...resources)
Besides the public API, the following browser-context methods will also be available:
σ.$(selector, context = document)
σ.$$(selector, index = null, context = document)
σ.$x(expression, index = null, context = document)
σ.$number(data, decimal = null, index = null, property = 'textContent')
σ.$string(data, property = 'textContent')
σ.$regexp(data, pattern, index = null, property = 'textContent')
To enable overloading, simply call the puppeteer
property exposed by this package.
Since version 5.0.0
you can specify a list of hooks to apply to created pages.
For instance, to enable ad-blocking (using @cliqz/adblocker-puppeteer
):
const { fullLists, PuppeteerBlocker } = require('@cliqz/adblocker-puppeteer');
const { promises } = require('fs');
async function adblock(page) {
const fetch = (url) => {
let handler = url.startsWith('https://') ? require('https').get : require('http').get;
return new Promise((resolve, reject) => {
return handler(url, (response) => {
if (response.statusCode !== 200) {
return reject(`Unexpected status code: ${response.statusCode}.`);
}
let result = '';
response.on('data', (chunk) => {
result += chunk;
});
response.on('end', () => {
return resolve({ text: () => result });
});
});
});
};
await PuppeteerBlocker.fromLists(fetch, fullLists, { enableCompression: false }, {
path: '/tmp/adblocker.bin',
read: promises.readFile,
write: promises.writeFile,
}).then((blocker) => blocker.enableBlockingInPage(page));
return page;
}
And then simply pass hooks hooks to newPage()
:
let page = await browser.newPage(adblock);
This package is versioned based on the underlying puppeteer
minor version:

To compile your own version of Chromium check the Ansible playbook instructions.
Lambda Layers is a new convenient way to manage common dependencies between different Lambda Functions.
The following set of (Linux) commands will create a layer of this package alongside puppeteer-core
:
git clone --depth=1 https://github.com/alixaxel/chrome-aws-lambda.git && \
cd chrome-aws-lambda && \
make chrome_aws_lambda.zip
The above will create a chrome-aws-lambda.zip
file, which can be uploaded to your Layers console.
The folks
@shelfio
also maintain and publish AWS Lambda Layers of this package.
Since version 1.11.2
, it's also possible to use this package on Google/Firebase Cloud Functions.
The only additional requirement is that iltorb
must also be added as a dependency:
npm install iltorb --save-prod
According to our benchmarks, it's 40% to 50% faster than using the off-the-shelf puppeteer
bundle.
The Chromium binary is compressed using the Brotli algorithm.
This allows us to get the best compression ratio and faster decompression times.
