Decoding from API using stbx-js #86

Open wires opened 5 years ago

wires commented 5 years ago

From https://hackmd.io/xtnHs1NtTcKGWjyq95Fgiw;

It should now be possible to decode transactions "DHT" (Distributed Hash Table) style.

Related issues:

Decode transactions from hash

usecase: when surf to statebox.cloud/##:hash we want see the wiring diagram on the left hand side in statebox studio.

encode wiring diagram in the browser

API:

baseUrl = https://us-central1-process-io.cloudfunctions.net

Return format

{ hash: "caca1234" // transaction SHA512 hash hex encoded
, tx: "cacabeefbabe2883" } // transaction hex encoded

Example:

<html>
    <head>

        <script src="//unpkg.com/@statebox/stbx-js"></script>
    </head>
    <body>
    <script>

            partition: [0, 1, 0, 1, 0, 0],
            names: ["x", "y"]
        }

        const mydiagram = {
            name: "z",
            width: 1,
            pixels: [1, 2],
            names: ["s", "t"]
        }

        const wiring = {
            nets: [mynet],
            diagrams: [mydiagram],
            // make nodes in the diagram point to net "a"
            labels: [0, 0]
        }

        const transaction = {
            wiring: wiring,
            previous: "deadbeef"
        }

        /* encoding and hashing the wiring */
        const thex = Stbx.encode(transaction)
