Question 1

How to deploy a Rails app with Jets?

Accepted Answer

Add the `jets-rails` and `jets` gems to your Gemfile, run `jets init` to set up the project, then use `jets deploy` to push it to AWS Lambda. The official docs provide detailed Rails-specific guides for configuration and best practices.

Question 2

Jets vs Serverless Framework for Ruby?

Accepted Answer

Jets is Ruby-specific and offers seamless integration with Rails and Sinatra out of the box, while Serverless Framework supports multiple languages but may require more manual configuration for Ruby apps. Jets is better for teams focused solely on Ruby with AWS Lambda.

Question 3

Can Jets handle WebSocket connections?

Accepted Answer

AWS Lambda has limitations with persistent connections, so Jets apps typically rely on API Gateway WebSocket support, which requires additional AWS service integration and might not be as straightforward as traditional server-based solutions.

Question 4

What are the cost implications of using Jets?

Accepted Answer

Costs are based on AWS Lambda pricing, which charges per request and execution duration. Jets is open-source, but you must manage concurrency and scaling settings to optimize expenses, as high traffic can increase bills significantly.

Question 5

How to manage database connections in a serverless Jets app?

Accepted Answer

Use connection pooling adapters or AWS RDS Proxy to handle database connections efficiently in Lambda's stateless environment. Traditional persistent connections can lead to issues, so Jets docs recommend configuring for serverless patterns.

Question 6

Does Jets support custom domains and SSL certificates?

Accepted Answer

Yes, Jets integrates with AWS services like API Gateway and Certificate Manager to set up custom domains and SSL, but configuration requires AWS knowledge and might involve additional steps beyond basic deployment.
