git clone https://github.com/CityOfZion/NeoLink.git

npm install

npm run start (for development with live reload)

npm run build (production)

Your unpacked extension will be in the ./build/ folder.

See https://developer.chrome.com/extensions/getstarted#unpacked for instructions on manually loading an unpacked Chrome extension in developer mode.

Use NeoLink with your dApp

Add the following code to your dApp:

<input type='text' id='contractScriptHash' />
<input type='text' id='operationName' />
<input type='text' id='runInvokeArgument1' />
<input type='text' id='runInvokeArgument2' />
<input type='text' id='assetType' />
<input type='text' id='assetAmount' />

<button id="runInvokeButton">Invoke</button>
<script>
document.getElementById("runInvokeButton").addEventListener("click",
    function() {
      var scriptHash = document.getElementById("contractScriptHash").value
      var operation = document.getElementById("operationName").value
      var invokeArg1 = document.getElementById("runInvokeArgument1").value
      var invokeArg2 = document.getElementById("runInvokeArgument2").value
      var type = document.getElementById("assetType").value
      var amount = document.getElementById("assetAmount").value

      var invocationObject = {
        'scriptHash': scriptHash, // Your contract's script hash.
        'operation': operation,   // Operation as defined in your contract.
        'arg1': invokeArg1,       // Depending on your input/contract, you may need to use u.str2hexstring, u.reverseHex
        'arg2': invokeArg2,       // or other utility methods from neon-js for these arguments.
        'assetType': type,        // NEO or GAS currently.
        'assetAmount': amount     // Amount, decimals allowed for GAS.
      }

      window.postMessage({ type: "NEOLINK_SEND_INVOKE", text: invocationObject }, "*");
}, false);
</script>

Please note that currently the code is limited to a maximum of two arguments to the smart contract.
