web3 with NativeScript
How can I use the web3.js library (for Ethereum development) in NativeScript?
I tried:
npm install web3@0.20.7 --save
const Web3
=require('https://cdn.jsdelivr.net/gh/ethereum/web3.js/dist/web3.min.js');
const Web3 = require("./web3.min.js");
console.log(Web3)
Also, I added the NativeScript plugin nativescript-nodeify
In the first three cases, I get an exception saying (amongst others) "Calling js method onCreate failed"
Note: I explicitly do not want to go via a back end to handle the interaction with Ethereum
