What is claudia?

What it is

Claudia open-source JavaScript tool. It deploys Node.js projects to AWS Lambda and API Gateway. It lives in Node.js, AWS, serverless ecosystem. It is npm package, MIT license, GitHub repo. Repository metadata lists JavaScript language, MIT license, 3882 stars, 275 forks, 27 open issues, 11 year age, last push 2026-05-03. Topics include api-gateway, aws, aws-lambda, claudia, javascript, nodejs, serverless. Homepage is claudiajs.com.

Concrete problem: AWS deployment setup tedious, error-prone. Developers must configure Lambda functions, API Gateway endpoints, AWS credentials, deployment workflow, files sent to Lambda. Claudia automates deployment and configuration tasks. It sets things up way JavaScript developers expect. It lets developers focus on business problems, not AWS deployment workflow. README also links video showing microservice create and deploy under 5 minutes. FAQ compares manual deployment and other tools, including Serverless, Apex, Swagger, Seneca. README links Example Projects for sample code.

Key capabilities

  • Deploys Node.js projects to AWS Lambda.
  • Configures API Gateway for deployed Lambda functions.
  • Automates deployment and configuration tasks for AWS Lambda and API Gateway.
  • Supports customising deployments, including what gets sent to Lambda and how it is used.
  • Provides command-line usage for deployment operations, with options documented in README.
  • Works with claudia-api-builder, so API Gateway can act as lightweight JavaScript web server.
  • Works with claudia-bot-builder, so chat bots for various platforms can be created and deployed.

Who uses it and how

  • JavaScript developers move Node.js applications onto AWS Lambda without manually assembling AWS deployment workflow.
  • Teams building HTTP APIs expose Node.js functions through API Gateway.
  • Bot developers use claudia-bot-builder to deploy chat-bot handlers to AWS.
  • API developers use claudia-api-builder to build lightweight API services over API Gateway.
  • Users follow Getting started guide: set up AWS credentials, run hello-world example, then customise files and settings sent to Lambda.

Getting started

Install claudia package from npm. Read Getting started guide for credential setup and hello-world example, then use command-line options to deploy or customise Node.js project.

When to use it — and when not to

Use Claudia when target is AWS Lambda and API Gateway, and code is Node.js. Less suitable when project needs non-AWS infrastructure, non-JavaScript runtime, or hosted deployment service, because README points to AWS credentials and command-line deployment. Metadata shows 27 open issues and no listed contributor count, so check maintenance status before adopting for long-lived services.

Claudia.js

npm npm npm

Claudia makes it easy to deploy Node.js projects to AWS Lambda and API Gateway. It automates all the error-prone deployment and configuration tasks, and sets everything up the way JavaScript developers expect out of the box. This means that you can get started with Lambda and API Gateway easily, and focus on solving important business problems instead of dealing with AWS deployment workflows. Check out this video to see how to create and deploy a microservice in under 5 minutes.

Claudia.js Introduction Video

With the help of Claudia builder projects, you can also use API Gateway as if it were a lightweight javascript web server, or create and deploy chat bots for various platforms easily.
