Chromium Binary for AWS Lambda and Google Cloud Functions
npm install chrome-aws-lambda
Chromium Binary for AWS Lambda and Google Cloud Functions
``shell`
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 also need to install the corresponding version of puppeteer-core (or puppeteer):
`shell`
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 all the currently supported AWS Lambda Node.js runtimes out of the box.
`javascript
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);
};
`
`javascript
const chromium = require('chrome-aws-lambda');
const playwright = require('playwright-core');
(async () => {
const browser = await playwright.chromium.launch({
args: chromium.args,
executablePath: await chromium.executablePath,
headless: chromium.headless,
});
// ...
await browser.close();
})();
`
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 | Provisions a custom font and returns its basename. |args
| | {!Array | Provides a list of recommended additional Chromium flags. |defaultViewport
| | {!Object} | Returns more sensible default viewport settings. |executablePath
| | {?Promise | Returns the path the Chromium binary was extracted to. |headless
| | {!boolean} | Returns true if we are running on AWS Lambda or GCF. |puppeteer
| | {!Object} | Overloads puppeteer and returns the resolved package. |
The Amazon Linux 2 AWS Lambda runtime is no longer provisioned with any font faces.
Because of this, this package ships with Open Sans, which supports the following scripts:
* Latin
* Greek
* Cyrillic
To provision additional fonts, simply call the font() method with an absolute path or URL:
`typescript`
await chromium.font('/var/task/fonts/NotoColorEmoji.ttf');
// or
await chromium.font('https://raw.githack.com/googlei18n/noto-emoji/master/fonts/NotoColorEmoji.ttf');
> Noto Color Emoji (or similar) is needed if you want to render emojis.
> For URLs, it's recommended that you use a CDN, like raw.githack.com or gitcdn.xyz.
This method should be invoked _before_ launching Chromium.
> On non-serverless environments, the font() method is a no-op to avoid polluting the user space.
---
Alternatively, it's also possible to provision fonts via AWS Lambda Layers.
Simply create a directory named .fonts and place any font faces you want there:
`
.fonts
├── NotoColorEmoji.ttf
└── Roboto.ttf
Afterwards, you just need to ZIP the directory and upload it as a AWS Lambda Layer:
`shell`
zip -9 --filesync --move --recurse-paths .fonts.zip .fonts/
Since version 8.0.0, it's possible to overload puppeteer with the following convenient API:
`typescript
interface Browser {
defaultPage(...hooks: ((page: Page) => Promise
newPage(...hooks: ((page: Page) => Promise
}
interface BrowserContext {
defaultPage(...hooks: ((page: Page) => Promise
newPage(...hooks: ((page: Page) => Promise
}
interface Page {
block(patterns: string[])
clear(selector: string)
clickAndWaitForNavigation(selector: string, options?: WaitForOptions)
clickAndWaitForRequest(selector: string, predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForRequest(selector: string, predicate: ((request: HTTPRequest) => boolean | Promise
clickAndWaitForResponse(selector: string, predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForResponse(selector: string, predicate: ((request: HTTPResponse) => boolean | Promise
count(selector: string)
exists(selector: string)
fillFormByLabel(selector: string, data: Record
fillFormByName(selector: string, data: Record
fillFormBySelector(selector: string, data: Record
fillFormByXPath(selector: string, data: Record
number(selector: string, decimal?: string, property?: string)
selectByLabel(selector: string, ...values: string[])
string(selector: string, property?: string)
waitForInflightRequests(requests?: number, alpha: number, omega: number, options?: WaitTimeoutOptions)
waitForText(predicate: string, options?: WaitTimeoutOptions)
waitUntilVisible(selector: string, options?: WaitTimeoutOptions)
waitWhileVisible(selector: string, options?: WaitTimeoutOptions)
withTracing(options: TracingOptions, callback: (page: Page) => Promise
}
interface Frame {
clear(selector: string)
clickAndWaitForNavigation(selector: string, options?: WaitForOptions)
clickAndWaitForRequest(selector: string, predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForRequest(selector: string, predicate: ((request: HTTPRequest) => boolean | Promise
clickAndWaitForResponse(selector: string, predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForResponse(selector: string, predicate: ((request: HTTPResponse) => boolean | Promise
count(selector: string)
exists(selector: string)
fillFormByLabel(selector: string, data: Record
fillFormByName(selector: string, data: Record
fillFormBySelector(selector: string, data: Record
fillFormByXPath(selector: string, data: Record
number(selector: string, decimal?: string, property?: string)
selectByLabel(selector: string, ...values: string[])
string(selector: string, property?: string)
waitForText(predicate: string, options?: WaitTimeoutOptions)
waitUntilVisible(selector: string, options?: WaitTimeoutOptions)
waitWhileVisible(selector: string, options?: WaitTimeoutOptions)
}
interface ElementHandle {
clear()
clickAndWaitForNavigation(options?: WaitForOptions)
clickAndWaitForRequest(predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForRequest(predicate: ((request: HTTPRequest) => boolean | Promise
clickAndWaitForResponse(predicate: string | RegExp, options?: WaitTimeoutOptions)
clickAndWaitForResponse(predicate: ((request: HTTPResponse) => boolean | Promise
fillFormByLabel(data: Record
fillFormByName(data: Record
fillFormBySelector(data: Record
fillFormByXPath(data: Record
getInnerHTML()
getInnerText()
number(decimal?: string, property?: string)
selectByLabel(...values: string[])
string(property?: string)
}
`
To enable this behavior, simply call the puppeteer property exposed by this package.
> Refer to the TypeScript typings for general documentation.
When overloaded, you can specify a list of hooks to automatically apply to pages.
For instance, to remove the Headless substring from the user agent:
`typescript
async function replaceUserAgent(page: Page): Promise
let value = await page.browser().userAgent();
if (value.includes('Headless') === true) {
await page.setUserAgent(value.replace('Headless', ''));
}
return page;
}
`
And then simply pass that page hook to defaultPage() or newPage():
`typescript`
let page = await browser.defaultPage(replaceUserAgent);
> Additional bundled page hooks can be found on /build/hooks.
This package is versioned based on the underlying puppeteer minor version:

Patch versions are reserved for bug fixes in chrome-aws-lambda and general maintenance.
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:
`shell`
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.
Alternatively, you can also download the layer artifact from one of our CI workflow runs.
Since version 1.11.2, it's also possible to use this package on Google/Firebase Cloud Functions.
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.
