description Chalice (AWS) Overview
Chalice is an open-source Python framework from Amazon Web Services for building serverless applications. It provides tools for deploying Python code to AWS Lambda and configuring related services, including API Gateway, through application definitions and route declarations. Chalice is intended for Python developers who want a lightweight way to create and manage event-driven web APIs without manually assembling every deployment resource.
help Chalice (AWS) FAQ
How does AWS Chalice create an HTTP API?
Chalice lets you declare a route in Python with `@app.route`, then deploys the application to AWS Lambda and Amazon API Gateway with `chalice deploy`. The official quickstart creates a project with `chalice new-project` and returns a URL such as an API Gateway development endpoint. [AWS Chalice documentation](https://chalice.readthedocs.io/en/stable/)
Can Chalice handle events other than API Gateway requests?
Yes, Chalice supports event sources such as SNS and SQS, pure Lambda functions, and WebSocket APIs. Its documentation also includes blueprints, authorizers, CORS, and continuous-deployment features.
Does Chalice create IAM permissions automatically?
Chalice includes automatic IAM policy generation based on the AWS resources declared by the application. Developers still need to review the generated permissions and configure credentials and deployment access for the target AWS account.
How are development stages represented in Chalice?
A basic `chalice deploy` creates a development stage, and the quickstart shows an endpoint ending in `/dev`. Chalice configuration can define separate stages so development and production settings do not have to share the same environment values.
