product asset service

Product Asset service GraphQL API using Graphene in a Django server

What is here

• Product Asset GraphQL API that integrates with ethereum product asset contracts
• GraphQL UI

Using this

python -m venv python-graphene-graphql-ve
pip install -U pip
pip install -r requirements.txt

Run service: startups service on http://127.0.0.1:5000

cd c:\github\ProductAssetService
flask run --host 0.0.0.0

You can now query this graphql api with: http://127.0.0.1:5000/graphql

Dependent on these local services

IPFS local service

Setting up IPFS: https://www.richcanvas3.com/ipfs-vue-nft-attribute-display

To run ipfs on local host. Can run this in any directory because it is globally defined

ipfs daemon

Ethereum Private Network local service

Setting up ethereum private network: https://www.richcanvas3.com/ethereum-private-network

To run ethereum private network: Need to run this in c:\ethereum-nodes directory.

cd c:\ethereum-nodes
geth --datadir node1 --port 30308 --bootnodes enode://dd56ba62106a591288316f5b487ac0fc84046ba5438fc4e18e8d1b24bd33a6f024e32dacaf76d90912aaa198a8bebb5b8b9d53ffa47ebfeef4fd25430e21a10a@127.0.0.1:0?discport=30305 --networkid 12345 --unlock 0x4FB0032AA225a94EdB257ae1d2338DfDc6d23e7F --password password.txt --http --allow-insecure-unlock --http.corsdomain "" --http.vhosts "" --http.addr "0.0.0.0" --authrpc.port 8560 --http.port 8546 --ipcpath=node1/geth.ipc --http.api="eth,net,web3,personal,web3" --rpc.enabledeprecatedpersonal --rpc.gascap 0 --rpc.txfeecap 0 --verbosity "4"

Then you need to startup another cmd prompt, startup geth client and startup miner. Make sure you give the blockchain time to initialize.

cd c:\ethereum-nodes
geth attach \.\pipe\node1\geth.ipc
personal.unlockAccount(eth.accounts[0])
Passprase: password
miner.setEtherbase("0x4FB0032AA225a94EdB257ae1d2338DfDc6d23e7F")
miner.start(1)

Redis Cache local service

Setting up Redis:

To startup redis you need to first go to ubuntu environment wsl. Then startup redis

wsl
sudo service redis-server start
enter: --find in linux credentials--
redis-cli

Redis should now be running on 127.0.0.1:6379

Ethereum Contracts called by service

Contracts are found in C:\github\web3store\contracts

View these on visual studio code => remix extension

OpenSea collections retrieved from

decentraland key is in keys file

"decentraland" "decentraland-wearables"

GraphQL example queries

Synch decentraland assets "land" and "wearables" from OpenSea to this private network After sync of land and wearables make sure and update the .env file with contract address. Search for contract:

query {
  synchProducts  { 
    products  {
        name
    }
  }
}

Sync decentraland categories (defined within local files) After sync of categories make sure and update the .env file with contract address. Search for contract:

query {
  synchCategories  { 
    categories  {
        name
    }
  }
}

Get Categories

query {
  category (slug: "/category/1")  { 
    id
    name
    products {
      id
      name
    }
    childs {
      id
      name
      products {
        id
        name
      }
      
      childs {
        id
        name
        products {
          id
          name
        }
