Package Exports

lambda-stream
lambda-stream/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (lambda-stream) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Lambda-Stream

This library adds types and local support for AWS Lambda Response Streaming. Locally, it'll buffer and return the entire response.

In AWS Lambda, it'll simply use the global awslambda.streamifyResponse.

This library exposes a ResponseStream class, the streamifyResponse method, and isInAWS method.

Works like this:

import { APIGatewayProxyEvent } from "aws-lambda";
import { streamifyResponse, ResponseStream } from 'lambda-stream'

export const handler = streamifyResponse(myHandler)

async function myHandler (event: APIGatewayProxyEvent, responseStream: ResponseStream): Promise<void> {
        console.log('Handler got event:', event)
        responseStream.setContentType("text/plain");
        responseStream.write("Hello, world!");
        responseStream.end();
}

Or in commonjs:

'use strict';
const { streamifyResponse } = require('lambda-stream')

module.exports.hello = streamifyResponse(
    async (event, responseStream, context) => {
        responseStream.setContentType("text/plain");
        responseStream.write("Hello, world!");
        responseStream.end();
    }
);
