Local SAM Development

This is a local developmemnt server for SAM applications that is able to emulate API Gateway, Lambda, DynamoDB, and S3. It is a great way to test your serverless applications locally before deploying them to AWS.

Sample

import localDevBuilder from '@timmons-group/local-sam-dev/builder.js';

import { createServer as vite } from 'vite';

// These are the parameters normally used in the template
// These are not environment variables, but are passed in as parameters
const parameters = {
    "Website": "Test",

};
const overrides = {
    "CustomDomainName": "localhost:4000",
};



const frontend_server = await vite({
    root: `../frontend/`,
    configFile: `../frontend/vite.config.js`,
});
frontend_server.httpServer.listen(4002);

const server = await localDevBuilder
    .withTemplate(`sam/template.yaml`)
    .withAppName(`Test`)
    .withParameters(parameters)
    .withOverrides(overrides)
    .withPort(4000)
    .withSSL({
        store: true,
    })
    .withFrontend({
        forward: 4002
    })
    .build();

console.log(server.schema);

This will create a server on port 4000 and a vite server on 4002.
