Run Browsershot on AWS Lambda with Sidecar for Laravel

This package allows you to run Browsershot on AWS Lambda through Sidecar.

You won't need to install Node, Puppeteer or Google Chrome on your server. The heavy lifting of booting a headless Google Chrome instance is happening on AWS Lambda.

Requirements

This package requires that spatie/browsershot and hammerstone/sidecar have been installed in your Laravel application.

Follow their installation and configuration instructions. (You can skip the installation of puppeteer and Google Chrome for Browsershot though.)

Installation

You can install the package via composer:

You can publish the config file with:

Register the BrowsershotFunction::class in your sidecar.php config file.

Deploy the Lambda function by running:

See Sidecar documentation for details.

[!Note] You should redeploy the Lambda function, whenever you upgrade spatie/browsershot.

Usage

You can use BrowsershotLambda like the default Browsershot-class coming from the Spatie package. All you need to do is replace Browsershot with BrowsershotLambda.

Warming

sidecar-browsershot supports warming for faster execution.

To enable this feature set the SIDECAR_BROWSERSHOT_WARMING_INSTANCES variable in your .env to the desired number of instances Sidecar should warm for you.

Alternatively you can publish the sidecar-browsershot.php config file and change the warming setting yourself.

Reading source from S3

You can store an HTML file on AWS S3 and pass the path to Lambda for it to create the PDF or image from. This is necessary for large source files in order to avoid restrictions on the size of Lambda requests.

Saving directly to S3

You can store your file directly on AWS S3 if you want to keep it there, or to avoid the size limit on Lambda responses.

You just need to pass a path and optional disk name (default: 's3') to the saveToS3 method.

• You must have an S3 disk defined in config/filesystems.php
• You must give S3 write permissions to your sidecar-execution-role

Image Manipulation

Like the original Browsershot package, you can manipulate the image size and format.

To perform image manipulations on the screenshot, you need to install the optional dependency spatie/image. v3 or higher is required.

Note
If you're using fit() in combination with saveToS3, the image will be downloaded from S3 to your local disc, manipulated and then uploaded back to S3.

Register Custom Fonts

By default, sidecar-browsershot includes the "Noto Color Emoji"-font, to ensure that emojis are rendered correctly. If you want to use custom fonts, you can put them all into a resources/sidecar-browsershot/fonts-folder. (You can customize the location of that folder in the sidecar-browsershot.fonts config)

sidecar-browsershot will include all files in that folder when deploying the Lambda function and will register them automatically in Chromium for you.

Testing

The testsuite makes connections to AWS and runs the deployed Lambda function. In order to run the testsuite, you will need an active AWS account.

We can use the native sidecar:configure artisan command to create the necessary AWS credentials for Sidecar. First copy the testbench.example.yaml file to testbench.yaml. Then run ./vendor/bin/testbench sidecar:configure to start the Sidecar setup process. (You only have to do the setup once)

After finishing the Sidecar setup process, you will have received a couple of SIDECAR_* environment variables. Add these credentials to .env.

Now we can deploy our local BrowsershotFunction to AWS Lambda. Run the following command in your terminal, before executing the testsuite.

After the successful deployment, you can run the testsuite.
