cdk-http-openapi

CDK Construct that lets you build AWS Api Gateway Http Api, backed by Lambdas, based on a OpenAPI spec file.

Features

[] Deploy Api Gateway Http Api based on a OpenAPI spec file. [] Each API Route will be backed by 1 NodeJS lambda. [] Configure CORS for your API. [] Add custom domain (eg: https://my-awesome-api.my-domain.com) to your API. [] Enable custom authorizers to Http Api Lambda integrations. [] Customize your lambdas's memory, timeouts, log retention, env variables and other stuff.

Setup

Add latest package to your project with npm/yarn

npm i --save cdk-http-openapi
yarn add -D cdk-http-openapi

Start using cdk constructs in your infrastructure definition Examples

import { HttpOpenApi } from 'cdk-http-openapi'

// ... in your stack definition
const api = new HttpOpenApi(this, 'MyApi', {
    serviceName: 'my-service',
    openApiSpec: './openapi.yml',
    lambdasSourcePath: './dist/src' // optional. It defaults to './.build/src'
    integrations: [
        {
            operationId: 'getEntity', // for each operation you define in your OpenAPI spec
            handler: 'api.getEntity', // you can register a lambda handler to handle your http request
        },
        {
            operationId: 'storeEntity',
            handler: 'api.storeEntity',
            timeoutSeconds: 5,
            memorySize: 512,
            env: { 
                DB_HOST: '...',
                DB_USERNAME: '...',
                DB_PASSWORD: '...'
            },
        }
    ]
});

const domainName = 'my-awesome-api.cool.io';
const certificateArn = `arn:aws:acm:${AWS_REGION}:${AWS_ACCOUNT}:certificate/${CERTIFICATE_ID}`;
const hostedZone = 'cool.io';

api.enableCustomDomain({domainName, certificateArn, hostedZone});
