TechU Bank OAuth Server

Light OAuth2 Server for training purposes.

This project implementes the OAuth2 accessCode flow.

Understanding OAuth2 and Building a Basic Authorization Server of Your Own: A Beginner’s Guide Control sessions via JWT tokens

Features

Supports /authorize and /token endpoints
Validation Authorities (VA) can check if tokens and scopes are valid
Persist JWT tokens in a MongoDB instance
Validate user credentials against a MongoDB collection (users)
Remove tokens (logout)

API Documentation

The API documentation is written following the Open API v2 specification in a Swagger YAML file.

You can find all the specification versions in ws-doc folder. It's automatically rendered using swagger-ui library.

If you want to check the documentation and try any endpoint (it only works in localhost):

Start the nodejs server

$ npm install
$ npm run start

Access the [ws-doc link|http://localhost:4000/ws-doc]
You will be able to test the endpoints setting the apki-key variable with the value "test"

Quick Start

Create a users collection in a MongoDB instance. You can use mlab for testing purposes.

// The following example has set the password to "secret"
{
	"username": "sagan",
	"first_name": "Peter",
	"last_name": "Sagan",
	"nif": "12345678Y",
	"birth_date":  {
        "$date": "1978-10-24T08:55:09.820Z"
    },
	"phone": "+34 666-66-66-66",
	"email": "[email protected]",
	"password": "$2b$10$uT37t75jAruP3ZTqnx8eMu0aGtjwK4qX7pXs4kn9IOw4tEYXncn1K",
	"status": "ACTIVE",
	"logged": false,
	"register_date":  {
        "$date": "2018-10-24T08:55:09.820Z"
    },
	"user_status": "ACTIVE",
	"address": {
		"street": "Bike Avenue",
		"zip_code": "496978",
		"city": "Dublin",
		"country": "Ireland"
	}
}

Create a .env file on the base path with MongoDB credentials

MLAB_HOST=<mongo-host>
MLAB_DATABASENAME=<mongo-databasename>
MLAB_USERNAME=<username>
MLAB_PASSWORD=<pwd>

Install dependencies and launch the server

$ npm install

$ npm run start

$ npm run start

Development

Requirements

This project needs:

Nodejs 8.4+
Docker 17+ if you want to publish a new docker image or run the latest TechU Bank docker image
Access to a MongoDB instace with a valid users collection.

Folders

bin: helpers
- pre-commit: execute linter and unit tests before a commit
- swagger-codegen.sh: parse swagger.vX.yaml and generates an api-client and a scaffold for the server side.
src: The API logic
ws-doc: Here you can find the swager.v1.yml with API's documentation
test: unit tests folder

Compilation

Stay on the base path where package.json is located.

$ npm install


If you want to update packages

$ npm update

Unit tests

Stay on the base path where package.json is located.

techu@techu> npm run test

If you want to execute unit tests on each change, execute the watcher command.

techu@techu> npm run watcher

To get coverage metrics run Instanbul

techu@techu> npm run coverage

Static code analysis

Linter

Linter is a light weight static code analysis recomended to be execute in every push to a branch, and may block the push.

techu@techu> npm run lint

Sonarqube - sonar-scanner Docker image

We have prepared a container with the software enough for run a static code analysis, execute unit tests, measure unit test coverage and upload the results to Sonarqube (free account).

You must have a Sonarqube API Key, configure properly the sonar-scanner.properties and run the command below:

$ docker run -it --env SONAR_API_KEY=<SONAR_USER_API_KEY> --mount type=bind,source="$(pwd)",target=/root/project -v "$(pwd)"/sonar-scanner.properties:/root/sonar-scanner/conf/sonar-scanner.properties davidrova/sonar-scanner:latest

To see the result click on this link.

The evaluation period has expired and we cannot upload more executions.

Don't worry, you can still perform static code analysis, but following a couple of additional steps.

Sonarqube - sonar Docker image

Launch a sonarqube instance (admin / admin)

$ docker run -d -p 9000:9000 -p 9092:9092 sonarqube

Generate a new API-KEY
Download sonar-scanner in localhost or use sonar-scanner Docker image sonar-scanner documentation
Run unit tests and coverage

$ npm run test
$ npm run coverage

Run sonar-scanner; sonar-scanner loads sonar-project.properties file

$ SONAR_API_KEY=<SONAR_API_KEY> sonar-scanner

View the results in Sonarqube

Hooks

We encourage to enable the pre-commit hook. It will avoid commiting a change if linter or unit tests fail.

$ cp bin/pre-commit .git/hooks/pre-commit

Continuous integration

The project is managed in bitbucket.org and we have automated an ease pipeline with the following step rules:

A commint into develop branch triggers:
- build
- lint
- unit tests
- sonar
- Increases the patch version
- Publish the artifact to npmrc registry
- Publish a new docker image into Docker Hub
A commit into master branch triggers:
- build
- lint
- unit tests
- sonar
- Increases the minor version
- Publish the artifact to npmrc registry
- Publish a new docker image into Docker Hub

NOTE: It's neccessary to generate a new key pair. Follow these instructions

TechU Bank OAuth Server Docker image

Start TechU Bank OAuth Server docker image

docker run -it -p 4000:4000 -p 4443:4443 -e PORT=4000 -e PORT_SSL=4443 -e MLAB_HOST=<host>:<port> -e MLAB_DATABASENAME=<databasename> -e MLAB_USERNAME=<mlab-username> -e MLAB_PASSWORD=<mlab-password> -e ENV=docker ${DOCKER_HUB_USERNAME}/techubank-auth-server

Stop TechU Bank OAuth Server docker image

docker stop techubank__oauth__server__testing

Remove TechU Bank OAuth Server docker image

docker rm techubank__oauth__server__testing

Building and push the docker image

docker build -t ${DOCKER_HUB_USERNAME}/techubank-oauth-server .
docker login --username=${DOCKER_HUB_USERNAME} --password=${DOCKER_HUB_PASSWORD}
docker push ${DOCKER_HUB_USERNAME}/techubank-oauth-server

Setup https

Create an self-signed SSL certificate

Write down the Common Name (CN) for your SSL Certificate. The CN is the fully qualified name for the system that uses the certificate. If you are using Dynamic DNS, your CN should have a wild-card, for example: *.api.com. Otherwise, use the hostname or IP address set in your Gateway Cluster (for example. 192.16.183.131 or dp1.acme.com).
Run the following OpenSSL command to generate your private key and public certificate. Answer the questions and enter the Common Name when prompted.

$ openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem


Country Name (2 letter code) [AU]:localhost
string is too long, it needs to be no more than 2 bytes long
Country Name (2 letter code) [AU]:ES
State or Province Name (full name) [Some-State]:MADRID
Locality Name (eg, city) []:MADRID
Organization Name (eg, company) [Internet Widgits Pty Ltd]:techubank
Organizational Unit Name (eg, section) []:techubank
Common Name (e.g. server FQDN or YOUR name) []:techubank
Email Address []:[email protected]

key.pem is the private key
certificate.pem is the self-signed certificate
Copy the pem files on the basepath
