serverless-typescript-demo

This is a very basic project demonstrating how to build a Serverless application using TypeScript, including linting and tests. You can refer to this blog post as a walkthrough of the code here. For more info about Serverless: https://serverless.com/

Define your aws credentials with the profile TEKsystems

edit ~/.aws/credentials

[TEKsystems]
aws_access_key_id = XXX
aws_secret_access_key = YYYY

Bake the serverless-docker image

Follow the README to bake the image

Run all demo commands into the docker container

N.B: I git clone the repo into my personal folder /Users/egagne/git_root

• Launch the runtime interactive container by mounting your development + aws credential directories as volumes (absolute path):

docker run -it -p 8000:8000 -v /Users/egagne/git_root:/src -v /Users/egagne/.aws/:/root/.aws:ro serverless-docker:latest /bin/bash

• Now into the Docker terminal, cd to your typescript demo git repo:

root@ea886cea5989:/# cd /src/serverless-typescript-demo
root@ea886cea5989:/src/serverless-typescript-demo# <type any following commands>

• To test the lambda version locally:

root@ea886cea5989:/src/serverless-typescript-demo# sls webpack invoke -f hello -p event.json

• To simulate API Gateway locally:

root@ea886cea5989:/src/serverless-typescript-demo# sls webpack serve

Then with your browser enter the URL: http://localhost:8000/hello

• To create the infrastructure in aws (Cloud-Formation template that will create S3 buckets, Api Gateway endpoint + Lambda Function):

root@ea886cea5989:/src/serverless-typescript-demo# sls deploy

Then with your browser enter the Endpoint URL the serverless give you, something like: https://oddletters.execute-api.us-west-2.amazonaws.com/dev/hello

• To run local mocha tests: npm run test (karma doesn't start the mocha tests, cannot figure out why)

root@ea886cea5989:/src/serverless-typescript-demo# npm run test:local

• To send a msg to kinesis:

root@ea886cea5989:/src/serverless-typescript-demo# sls invoke --function dataReceiver --path kinesis.json
