AWS lambda with playwright on python

---

💥 Usefully docs and articles:

• Official Documentation Docker - Playwright Python
• New for AWS Lambda – Container Image Support
• Running End-to-End Tests with Playwright on AWS Lambda

Why ❓

It's easy to play with a Playwright, and I'm feeling more comfortable instead of using Selenium. Sometimes times need to deploy a solution completely serverless and here can do that with AWS Lambda and playwright. I searched on the web for this solution but did not have luck with the python approach (don't look too hard).

⚽ Our goal

We want to build an AWS lambda based on docker images, this lambda will open a browser in headless mode and visit a website to extract it’s title and put in logs.

Dependencies

• nodejs v14.19.0
• npm
• Serverless Framework Core: 3.1.1
• Docker
• Python 3
• AWS Account (for test and deploy)
• aws-cli (for config de AWS profile)

🔤 Requirements configurations

• Config your AWS profile and credentials, aws configure in the terminal.

• Set your env file before notting, Example

  AWS_PROFILE=PROFILE
  AWS_REGION=eu-west-1
  STAGE=dev
  

Install dependencies

make install

All the app code is inside of app folder, feel free to try your code and test.

Note: always the handler is the main function on app/main.py

Build a docker image

make build

Deploy

make deploy stage=dev

This command deploy the serverless solution and create

• Cloudformation stack with all resources.
• S3 bucket with all the code or artifacts of the project.
• ECR repository to upload the docker image for the lambda.
• Lambda function.

Test the lambda

make deploy stage=dev

🍔 Output

$ ❯ make invoke stage=dev                                                                                                                                                                                                  4s  aws-lambda-playwright  18:07:22
