With everything set up, let’s install the AWS CLI and set up our credentials. Then, follow the steps in the official serverless docs to create an IAM User and Access Key. To get started, create an AWS free tier account. What is AWS Lambda?ĪWS Lambda is an event-driven, serverless computing platform from Amazon Web Services that runs code in response to events and automatically maintains the computing resources needed by that code.įor the examples in this tutorial, we’ll use AWS Lambda to run and manage our serverless functions. It has a hosted dashboard that allows you to import existing projects, track performance, troubleshoot, configure CI/CD and deployment policies, and get end-to-end serverless application lifecycle management. For one, it manages your code as well as your infrastructure and supports multiple languages, like Node.js, Python, Java, and more. The Serverless Framework has several advantages over other application frameworks. It provides structure, automation, and support for best practices out of the box, allowing you to focus on developing sophisticated, event-driven, serverless systems made of functions and events. The Serverless Framework allows you to design, deploy, debug, and protect serverless applications with minimal overhead and cost, all while providing the required infrastructure resources, like AWS, Azure, Google, etc. The Serverless Framework is an open source command-line interface (CLI) and hosted dashboard that enables comprehensive serverless application lifecycle management. The code is often executed within stateless containers that can be triggered by events like HTTP requests, queuing services, monitoring alerts, file uploads, scheduled events, database events, and more. The term serverless is misleading in the sense that servers still employ cloud service providers to run code for developers. Serverless computing is an execution paradigm for cloud computing in which the cloud provider allocates machine resources on-demand, managing servers on behalf of its clients. Feel free to clone the project to follow along. The full code for the project is available at the GitHub repository.

Building a serverless app with TypeScriptĭid you know that you can write and deploy your code on the cloud without having to worry about provisioning, maintaining, and scaling the underlying infrastructure? In this tutorial, we’ll learn how to build a serverless application using TypeScript and the Serverless Framework.
