bcfServer

This project is a BCF server implementation based on the BCF API using Node.js and MongoDB. It aims to quickly provide small servers to test the connection to BCF servers with other applications.

Table of content

Dependencies/Setup

All necessary Node.js packages can be taken from the Package.json. Furthermore a MongoDB is needed (local or cloud-based) where the server structure is built according to the following scheme:

- BcfServerCluster
  - MainDatabase
    - Projects Collection
    - Users Collection
  - GUID Database 1...n (can be retrieved from the Projects subcollection)
    - Comments Collection
    - Extensions Collection
    - Topics Collection
    - Users Collection
    - Viewpoints Collection

This version was built and tested with MongoDB Atlas Currently there is no frontend to create users, projects or extensions. All these processes must be entered manually into MongoDB. Before you can start the you need to create the file "nodemon.json" and fill it with the following information:

{
    "env": {
        "MONGO_ATLAS_URL": "Link_to_your_mongodb",
        "MONGO_ATLAS_MAIN_SERVER" : "name_of_main_db (in this case bcfServer)",
        "JWT_KEY": "your_jwt_secret",
        "SERVER_URL": "url_to_your_server (e.g. http://localhost:3000)"
    }
}

After everything is set browse in your terminal to the directory containing the "server.js" file and execute the following command:

    cd path/to/your/dir/bcfServer/
    npm start

Authentification

For reasons of simplification, the BCF server currently deviates from the authentication methods proposed in the BCF API. The following methods must be used to create and log in a user:

Signup User

Resource URL

POST /bcf/2.1/auth/signup

To create a user you have to send a valid token. The server is then checking for the role attached to your account. There are currently two roles in the BCF server: "user" and "admin". Only the admin is allowed to create new users. All others receive 401 Status code.

Example Request

POST /bcf/2.1/auth/signup
Body: 
{
  "id" : "john-doe@example.org",
  "name" : "John Doe",
  "password" : "myAmazingPassword",
  "role" : "user"
}

Example Response

Response Code: 201 - Created
Body: 
{
  "id" : "john-doe@example.org",
  "name" : "John Doe",
  "role" : "user"
}

Login User

Resource URL

POST /bcf/2.1/auth/login

At login we send our username and password to the server and receive a token back with which we can authenticate ourselves to the server for our requests. This part is currently not yet compliant with the BCF-API and will probably be changed in the future

Example Request

POST /bcf/2.1/auth/login
Body: 
{
  "id" : "john-doe@example.org",
  "password" : "myAmazingPassword",
}

Example Response

Response Code: 200 - OK
Body: 
{
    "message": "Authentication successful",
    "token": "ExampeTokenForRequestOperations"
}

Acknowledgement

The first steps in this project are inspired by Academind's tutorial series Building a RESTful API with Node.js, which offers a good introduction to the topic and gives a rough insight into the architecture of our server
