AWS-Lambda-fastify & NestJS Serverless example

This is used to show problem with Websocket Api communication

Installation

npm install

Build & Running the app

npm build

Launch the serverless offline

npm run start:sls

If all goes well the API Endpoint should be available on 3000 port and WS should be available on port 3001

http://localhost:3000 ws://localhost:3001

To test those

curl http://localhost:3000/dev/fastify or curl http://localhost:3000/dev/serverless

To Test WS endpoint use

npm install -g wscat

wscat -c ws://localhost:3001

To change between aws-lambda-fastify and serverless-fastify

Comment out the right handler from the serverless.yml file

    ws:
        # To test other
        # handler: src/aws-lambda-fastify.handler
        handler: src/serverless-fastify.handler
