The official repository for mec npm package. The mec package is designed to quickly deploy a MEC client in a nodejs application and quickly integrate with any service from a decentralized MEC network

Use-case

Searching for specific blockchain sub-network:

const mec = require('mec')
 
// mec.layer.init(your_password), by default set to 1234
mec.layer.init("1234")
 
mec.layer.search("signup")

Response contains interface needed to start new sub-network connection:

{
  "name": "signup",
  "enode": "enode://b61f72cb88eed0ea9c2214492186a473774a8a9bb3…38cc9d0230a81d8fde59724ea313fa@212.20.41.42:30303",
  "address": "0xeac784b35b697740a3dc17ec59247749cc298c37",
  "abi": [
    {
      "constant":true,
      "inputs":[0],
      "name":"abidata",

Starting new connection

mec.layer.start("signup")
// mec.layer.start(name_of_subnet_you_connecting)

Successfull response means that now you can interact with sub-network applications over http/ipc/API

Or your may create your own sub-network blockchain:

mec.newLayer("my")
// the name you set will be used to find you globaly

Successfull response means that now you can develop or anything else with your own sub-network blockchain.
