faast.js AWS run remote command example

This is a simple command line tool that runs a command on AWS Lambda. Note that every time this command is run, it creates a new lambda. It doesn't make much sense to invoke this script many times from an external program. Instead, adapt the script to handle a set of inputs from a file, or from another process, and invoke the exec function multiple times within a single process execution.

The -d, --dir option can be used to send a directory to the lambda function. This directory can contain a binary to run and inputs for the binary, for example.

Prerequisites

• Node 8+.

Installing dependencies

$ npm install

Building

$ npm run build

Using npm run watch will automatically compile changes on the fly if you're modifying the script.
