demo-backend

About

This is an example implementation of services and devices on the IOTA network using a weather station, FPGA, and a garage door opener. The IOTA network is still a young protocol with a lot of room for interpretation on how to best utilize it. While there have been attempts to market data for financial gain, I believe the more practical application lies in the sale of IoT devices with an ASIC POW chip to talk on the IOTA network effortlessly.

This demo server is essentially a means of managing devices and how they interact with the IOTA tangle.

Install

# yarn
yarn add @iftt/demo-backend
# npm
npm i --save @iftt/demo-backend

How to use

Create Environment file

create a file called .env with these keys and replacing the variables:

PORT=3001
JWT_SECRET=m7ugp0jKc4RoRJvXtnCJrETheIRZENay
JWT_EXPIRES=15d
WEATHER_API=00000000bec84a09aa12094c4b3eac071c733dbc80834fc5a8d02fe840000000
WEATHER_APP_API=000000005ac24e28a5d6f76bb4b710c4fa5c76f1129b4002905afe31c0000000
WEATHER_TANGLE_SEED=I9XZHZETFFDYRWISYGGONGSULUTERQXQYZRALTNXWXQMRIORUSTTCKJVYNHCBWKGSDVEKIBXMQMOJKPQBX

How to generate a unique JWT secret

# Linux
cat /dev/urandom |tr -dc a-zA-Z0-9|head -c${1:-32}
# OS X
cat /dev/urandom |LC_ALL=C tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1

How to generate a unique IOTA seed

# Linux
cat /dev/urandom |tr -dc A-Z9|head -c${1:-81}
# OS X
cat /dev/urandom |LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1

Create the NodeJS server

Option 1: download this repository and run from the lib

# clone the repo
git clone https://github.com/iftt/demo-backend.git
# install dependences
yarn # or npm install
# run the server
yarn run server  # npm run server

Option 2: install the npm package and run

After installing the package, create a JS file and input the following

// ES6
import '@iftt/demo-backend'
// ES5
require('@iftt/demo-backend')
