Reef-Lambda-Payments

Unofficial Serverless Payment API for the Reef blockchain. This repo was set-up as part of the Gitcoin Defi Hackathon.

AWS DynamoDB + Lambda codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API.

This codebase contains code written for the below hackathon bounty. https://gitcoin.co/issue/reef-defi/reef-finance-bounties/1/100026837

There are 3 repos that contain relevant code.

Storefront - https://github.com/rtre84/reef-payments-store
Products service - https://github.com/rtre84/reef-products-service
AWS Lambda Payment API - https://github.com/rtre84/reef-lambda-payments

To run the demo locally:

Git clone https://github.com/rtre84/reef-payments-store
Run yarn install
Run yarn dev

NOTE: The Polkadot / Reef finance specific code isn't completely functional in it's current state. All code is deployable and accessible locally. Unresolved bugs in the product and lambda service blocked the service from working end to end correctly.

Storefront Demo: https://eager-jang-5dfc4d.netlify.app/
Product Service: https://reef-frontend-product-service.herokuapp.com/health
Lambda API Gateway Service: https://1qnnysgv5d.execute-api.us-east-1.amazonaws.com/dev/

Getting started

Requires Node 8 or higher

Clone this repo, and cd into it:

git clone https://github.com/rtre84/reef-lambda-payments
cd reef-lambda-payments

Starting the local server

npm install
npm run start

This should start local DynamoDB emulator and Serverless offline. You can now make API calls against http://localhost:3000/api like this:

curl http://localhost:3000/api/articles

Serverless: GET /api/articles (λ: listArticles)
Serverless: The first request might take a few extra seconds
Serverless: [200] {"statusCode":200,"headers":{"Access-Control-Allow-Origin":"*","Access-Control-Allow-Credentials":true},"body":"{\"articles\":[]}"}

Running tests locally

npm test

See sample test run log and network traffic.

API

The API is described in the serverless.yml file.

Storage

For storage, AWS DynamoDB a managed serverless NoSQL database is used.

Deployment

To deploy the code to AWS, simply execute:

npm run deploy

This will use serverless to deploy the API as described in serverless.yml.

Once deployed, you can test the deployed API by executing:

npm run test:deployed
