Blockchain API

Blockchain API which handles GET of the block by height and POST of any new block with a non-blank body in the request.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Clone the repository to somewhere you want to work on it.

git clone <git url>

Installing

Navigate to the directory inside terminal and then:

npm install

Then just run:

node app.js

to start the server.

Use Postman or Curl at http://localhost:8000

Routing

Use the following to interact with the API

GET (Returns block)

Use this to GET the block at given height.

http://localhost:8000/api/block/{index}

set index = the desired height:

index = int

Example:

http://localhost:8000/api/block/5

{
    "hash": "3df18561aeb128cacb59ec38f5f21cdac0f099af37470e6eb10a7cc07ff4eb5d",
    "height": 5,
    "body": "Test Data #5",
    "time": "1549933540"
}

POST (puts block in chain)

Use this to POST the block with your given body to end of chain.

http://localhost:8000/api/block

set body = your data

body = string

Example:

POST
http://localhost:8000/api/block/
body = 'yes'

Pushed block {
  "hash": "5795e5778ce3968a9ff7ea2466efb3f7e7d97c030cf451827c9985acc8b38e79",
  "height": 10,
  "body": {
    "yes": ""
  },
  "time": "1549938441"
} 
to the chain!
