Setup

1. Configure a ./flow.json to deploy the 5 contracts to the Emulator Account

   https://docs.onflow.org/flow-cli/configuration/

   "contracts": {
     "Moments": "./contracts/Moments.cdc",
     "MomentsMarket": "./contracts/MomentsMarket.cdc",
     "FungibleToken": "./contracts/FungibleToken.cdc",
     "FUSD": "./contracts/FUSD.cdc",
     "NonFungibleToken": "./contracts/NonFungibleToken.cdc"
   },

   "accounts": {
     "emulator-account": {
       "address": "f8d6e0586b0a20c7",
       "keys": "xxxxx",
       "chain": "flow-emulator"
     }
   },

   "deployments": {
     "emulator": {
       "emulator-account": [
         "Moments",
         "MomentsMarket",
         "NonFungibleToken",
         "FungibleToken",
         "FUSD"
       ]
     }
   },

2. Configure .env with the Emulator HTTP server port and Emulator account address

Test

Run Jest testing suites to test contracts with Scripts and Transactions

1. Start the flow emulator in the same repo directory

   flow emulator

2. Deploy Contracts to the Emulator Account

   flow project deploy --network=emulator

3. npm test

   This runs all tests sequentially, so there are no overlapping transaction errors in the emulator - which look like this:

   invalid proposal key: public key 0 on account f8d6e0586b0a20c7 has sequence number 19, but given 18

   Once the test suites are run, 4 accounts will be set up, FUSD and Moments minted, sent, put up for sale, removed from the market, and bought/sold.

Use Cadence Scripts & Transactions

Examples:

• Simple Transaction

  flow transactions send ./transactions/accounts/setupAccount.cdc --signer emulator-account

• Transactions with Args Emulator

  flow transactions send ./transactions/FUSD/mintFUSD.cdc --arg Address:0xf8d6e0586b0a20c7 --arg UFix64:1000.0000 --signer emulator-account
  flow transactions send ./transactions/FUSD/sendFUSD.cdc --arg UFix64:1200.0000 --arg Address:0x01cf0e2f2f715450 --signer emulator-account

  Testnet

  flow transactions send ./transactions/accounts/setupAccount.cdc --network=testnet --signer testnet-account
  flow transactions send ./transactions/Moments/mintMoments.cdc --network=testnet --signer testnet-account --args-json '[{"type":"Address","value":"0x633d28d54651d07c"},{"type":"Int","value":"3"},{"type":"Dictionary","value":[{"key":{"type":"String","value":"name"},"value":{"type":"String","value":"test"}},{"key":{"type":"String","value":"ipfs"},"value":{"type":"String","value":"ipfs link string"}}]}]'

• Scripts

  flow scripts execute ./scripts/FUSD/getFUSDbalance.cdc --arg Address:0xf8d6e0586b0a20c7
  flow scripts execute ./scripts/Moments/getMoments.cdc --network=testnet --arg Address:0x633d28d54651d07c
  

• Using node scripts

  main({args}); Must be added to the bottom of the .js file to run the function **

  node transactions/FUSD/mintFUSD.js

Testnet Deployment

flow project deploy --network=testnet

Attribution

Most of the cadence smart contracts are templated off of the kitty-items example application.
