nodejs-MEC
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 1234mec.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", "outputs":[1], "payable":false, "stateMutability":"view", "type":"function" }, {}, {} ]}
Globaly available sub-networks
mec.layer.getInterface()
Response contains all available sub-networks interfaces:
{ "abi": [3], "address": "0xeac784b35b697740a3dc17ec59247749cc298c37", "enode": "enode://b61f72cb88eed0ea9c2214492186a473774a8a9bb318194ac38d3900062a11a0b48d1a4e8d36e04432c2e287e485f2f30a38cc9d0230a81d8fde59724ea313fa@212.20.41.42:30303", "name": "signup"},{ "abi": [3], "address": "0x1234567890123456789012345678901234567890", "enode": "enode://.....", "name": "main"}

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

INFO: Ready: true
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.
- at development newly created sub-networks can't be found outside your computer
