crumbl-hoster

Easy hosting server for the Crumbl™ platform

This application is a simple hosting service for the Crumbl™ technology patented by Cyril Dever.

Usage

1. Either you have set your own MongoDB environment compatible with crumbl-hoster's requirements:

   npm i crumbl-hoster && npm run compile && npm start

2. Or you start the Docker container:

   git clone https://github.com/cyrildever/crumbl-hoster.git && cd crumbl-hoster && docker-compose up --build -d

   You might want to use the ./cleanup script (or ./cleanup.bat on Windows) before launching any new Docker session (especially when you've built the NPM project).

Running the application will write a 'crumbl-hoster.log' file.

Production

Change or adapt the following environment variables if need be:

• HTTP_PORT: the HTTP port number (default: 8000);
• MONGO_DOMAIN: the MongoDB server name (default: localhost);
• MONGO_PORT: the MongoDB port number (default: 27017);
• MONGO_DB: the name of the MongoDB database (default: crumbl);
• MONGO_USERNAME: the MongoDB username;
• MONGO_PASSWORD: the MongoDB password for this username;
• MONGO_COLLECTION: the name of the collection to use (default: hoster).

API

// TODO Add headers identifying the requester.

The following endpoints are available:

• GET /crumbl

This endpoint returns the full crumbled string from the passed related hashered prefix of a Crumbl, eg. http://localhost:8000/crumbl?hasheredSrc=1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef&token=12345678-90ab-cdef-1234-567890abcdef1

It expects 2 mandatory arguments:

• hasheredSrc: the hashered prefix of the Crumbl;
• token: a valid token (in the form of a UUID string).

It returns a 200 status code if found along with a JSON object in the body respecting the following format:

{
  "crumbled": "<The full found crumbled string>",
  "hasheredSrc": "1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
}

• POST /crumbl

This endpoint records a crumbled string in the local database. It expects the request body to be the full crumbled string, eg.

$ curl --location --request POST 'localhost:8000/crumbl' --header 'Content-Type: text/plain' --data-raw '<The full crumbled string>'

It returns a 201 status code if success along with the verification hash string in the body.
