Lambda

A simplistic HTTP based lambda function implementation. Upload a zip file with Javascript / Typescript code that is run on an HTTP request.

Getting started

Install dependencies

% npm install

Create the folder where the source code will be uploaded.

% mkdir runner

Start the server

% npm start

The server will be running by default on port 8000 so you can access it on http://localhost:8000

Create a sample application with the following code in a file called index.js:

exports.handler = async (event) => {
  console.log(event);
  const res = {
    body: {
      message: 'hello world'
    }
  };
  return res;
}

Package the file in a zip file

% zip example.zip index.js

Upload the zip file to the server (using curl for example)

% curl -v -F upload=@example.zip http://localhost:8000/upload

Try posting an event to the server and you will see that the code you uploaded is running.

% curl -v -X POST -H 'Content-Type: application/json' -d '{ "hej": "hopp" }' http://localhost:8000/event
{"message":"hello world"}
