(23) Section Intro
(24) Why Bundling?
options
deploy all node_modules
NOPE
Node Lambda - with esbuild (integrated with CDK)
YES
webpack (hard to configure)
NOPE
why?
growing list of dependencies
typescript needs compilation to node_js
(25) Bundling with CDK Node Lambda
integrated with CDK
uses esbuild
npm install --save-dev esbuild@0
example dependency
npm i uuid @types/uuid
services/node-lambda/hello.ts
import {v4} from "uuid";
async function handler(event: any, context: any) {
return {
status: 200,
body: 'hello from lambda!' + v4()
}
}
export {handler}
infra/SpaceStack.ts
const helloLambdaNodeJs = new NodejsFunction(this, 'helloLambdaNodeJs', {
entry: join(__dirname, '..', 'services', 'node-lambda', 'hello.ts'),
handler: 'handler'
})
