Full-Stack Serverless Bun Template

A full template for a serverless application built using Bun.

Features:

• AWS CDK for infrastructure-as-code to define Cloud resources. (packages/cdk)
• Custom Lambda Layer for Bun that plays nicely with Hono. (packages/bun-layer)
• Lambda based API using Hono. (services/api)
• Static-hosted web application using React. (services/client)
• Everything is neatly configured behind a CloudFront distribution (packages/cdk)

How to use:

• bun run develop will start the development server.
• bun run build will bundle all code and CDK definitions.
• bun run package will zip up all code to deploy.
• bun cdk [...] alias for aws-cdk CLI in the correct working directory.
• bun cdk synth will synthesize a CloudFormation template.
• bun cdk diff will show a diff between deployed CloudFormation state and local changes.
• bun cdk deploy will deploy the application to AWS.

Development Server

The development server will hot-reload client changes. When using bun run develop the API server will also restart when changes are made.

Additionally, there's a proxy available in the development server that mimicks the CloudFront configuration. Any requests made to /api or /api/* will be forwarded to the API server locally. This way, you can hard code in your API request URLs in the client without worrying about local/deployed servers.
