How to Successfully Use Puppeteer on AWS Lambda for HTML to PDF Conversion

If you are looking to convert HTML to PDF using Puppeteer on AWS Lambda, you may have encountered some frustrating errors along the way. One common issue arises when trying to launch puppeteer or even when configuring your Lambda function. In this guide, we will walk through a proven solution that resolves these issues and allows you to use Puppeteer effectively in a Lambda environment.

The Challenge

Using Puppeteer to convert HTML to PDF on AWS Lambda can be tricky due to the headless nature of the browser and the various dependencies it requires. Many developers, just like you, have run into errors such as:

Module not found: Errors related to missing module paths.

BrowserFetcher issues: Problems creating a BrowserFetcher due to environmental constraints.

Undefined paths: Errors caused by incorrect paths or execution contexts.

To help you tackle these challenges, I'll share my experience and the setup that worked for me.

The Solution: Using Docker with AWS Lambda

To overcome these issues, I found that running Puppeteer within a Docker container was the easiest workaround. Here’s a step-by-step breakdown of my setup:

Step 1: Dockerfile Configuration

Create a Dockerfile that sets up your Lambda function with the required dependencies:

Step 3: Implementing the Handler

Create your Lambda function's handler in an index.js file as follows:

Step 4: Build and Deploy

Use the Docker image to build your application and deploy it to AWS Lambda.

Ensure you have all necessary permissions and environmental configurations checked.

Conclusion

By leveraging Docker to manage dependencies and run your Puppeteer code, you can effectively convert HTML to PDF on AWS Lambda without running into common pitfalls. This approach not only streamlines your function’s execution but also keeps your setup clean and organized.

With the above steps, I hope you can confidently integrate Puppeteer into your AWS Lambda projects. Don't hesitate to reach out if you encounter any issues or have further questions!
