Lambda deployments and response streaming 🚀☁️ #84

Streaming response upto 200 MB and deployments via GitHub Actions

Aug 15, 2025

In the previous issue, Lambda DevEx and SQS Fair Queues 🚀☁️ #83, we looked at the DevEx updates on Lambda and SQS Fair Queues.

Lambda hasn’t halted its Developer Experience updates. We see another groundbreaking enhancement with Lambda deployments via GitHub Actions, making CI/CD pipelines for serverless applications that use Lambda much more seamless with OIDC authentication, while GitHub Actions eliminates the need for manual deployments.

⭐ Pick of the month

This month’s Pick is “Lambda Response Streaming“.

Jones Zachariah Noel N (Author) shares about Streaming responses via Lambda functions with how to define and leverage the Node’s write() and Lambda’s pipeline() to implement streaming responses on Lambda to reduce the TTFB.
