Serverless Websocket API

Serverless AWS API Gateway with Websockets and Lambda

Description

This PoC shows a basic chat done with react and a websocket API done with API Gateway

Structure

The project is split into 2 folders:

packages/backend

That contains the backend files and

packages/chat-gui

that contains the GUI.

Backend

The backend is done in nodejs (V8.10) that is the one that currently is supported by AWS Lambda.

To install you need to do an npm i. To deploy you need to do an npm deploy that will deploy the GUI using Serverless. In order yto deploy, you need to have the aws-cli installed with some credentials configured like explained here: https://serverless.com/framework/docs/providers/aws/guide/credentials/

Frontend

The frontend is done in React JS using CRA2.

To install you need to do an npm i and to develop use npm run start to launch webpack dev server. To deploy you need to create a production build using npm run build and then I suggest upload the code to a website bucket in S3 using aws s3 cp build s3://name-of-bucket.
