Eco Rewards Hub

API to ingest and process passenger travel transactions and calculate eco rewards.

Installation

Node +12 and a MySQL compatible database are required. The Ubuntu set up is:

sudo apt-get install -y nodejs mariadb-server
# warning this will blank your root mysql password
sudo mysql -u root mysql -e "update user set authentication_string=password(''), plugin='mysql_native_password' where user='root'; flush privileges;"

Installing and running the service:

git clone [e-mail]:EcoRewards/eco-rewards-hub.git
npm install --save eco-rewards-hub
npm run migrate
npm start

Running with pm2:

pm2 start ecosystem.config.js

CLI commands

There are some CLI commands to help get set up:

npm run cli -- create-scheme [name]
npm run cli -- create-organisation [name] [schemeId]
npm run cli -- create-group [name] [organisationId]
npm run cli -- create-user [name] [email] [password] [role]
npm run cli -- export-all-members

Functional requirements

The scope of the API is defined by a number of user stories in cucumber format.

See features.

Non-functional requirements

• Swagger documentation
• Secure API access
• Continuous integration with automated tests

Decision log

Date	Decision	Reasoning
2019-11-01	Implement with node.js	Developers familiar with it, fast iteration speed
2019-11-01	Use a MySQL compatible database	Developers familiar with it, widely used
2019-11-01	Use AWS	It's convenient and widely used
2019-11-18	Do not use docker	Unnecessary for a project this size
2019-11-18	Make the code open-source	No need for private repository, cheaper tooling (Travis et al)
2019-11-18	Use travis CI	It's free
2019-11-18	Use cucumber to capture functional requirements	Track the evolution of requirements and use as a basis for functional tests
2019-11-18	Use use Koa	Widely used and supports promises
2019-11-18	Use db-migrate	Most widely used database migration tool
2019-11-18	Do not use an ORM	Seems like overkill when there are so few models
2019-11-18	Bcrypt passwords	Most secure, widely used method to salt passwords
2019-11-19	Basic auth for API access	Simple, widely used and easy to implement
2019-11-21	Swagger documentation	Comes with a slick UI and package to validate requests and responses
2019-11-21	Link based API responses	Reduces duplication in API responses. See this post
2019-11-27	Travis deployment	Simple, easy, as seen here
2019-11-27	PM2 process management	Makes the travis deployment easier
