Technologies used

(Add only the specific technologies you need to use until Midterm)

• (e.g. solidity, react, node, mysql)

Installation intructions

1. Ensure that npm, node, truffle and Ganache are installed.

2. Clone this repo, cd into the root dir and run

npm install

3. Ensure that Ganache is up and running and ensure that its RPC server (default: HTTP://127.0.0.1:7545) matches what's in truffle.js.

4. On a terminal, run the following commands to compile and migrate the smart contracts

truffle compile --all
truffle migrate --reset

Note the address of the ChanCore deployed contract for testing in step 6.

5. To open the truffle console, run the following command on the terminal:

truffle console

6. Once the truffle console is active, run the following commands to test ChanCore:

truffle(development)> var accounts;
undefined
truffle(development)> web3.eth.getAccounts(function(err,res){accounts=res;})
undefined
truffle(development)> accounts[0]
'0x627306090abab3a6e1400e9345bc60c78a8bef57'
truffle(development)> myC = ChanCore.deployed()
.
.
.
truffle(development)> myC.then(function(instance){return instance.totalSupply()})
BigNumber { s: 1, e: 0, c: [ 1 ] }
truffle(development)> myC.then(function(instance){return instance.ownerOf(0)})
'0x30753e4a8aad7f8597332e813735def5dd395028'
truffle(development)> myC.then(function(instance){return instance.ownerOf(1)})
'0x627306090abab3a6e1400e9345bc60c78a8bef57'
truffle(development)> myC.then(function(instance){return instance.getChan(0)})
[ 'AnimeGod',
  BigNumber { s: 1, e: 9, c: [ 1525245829 ] },
  BigNumber { s: 1, e: 0, c: [ 0 ] },
  true ]
truffle(development)> .exit

If you get output similar to above, then the ChanCore contract deployed successfully and the first CryptoChan called AnimeGod has been created. Note that the owner of AnimeGod is the ChanCore contract itself, which address should match the address printed in step 2 after running truffle migrate --reset.

6. Once the truffle console is active, run the following commands to test SaleClockAuction:

truffle(development)> sca = SaleClockAuction.deployed()
.
.
.
truffle(development)> sca.then(function(instance){return instance.isSaleClockAuction()})
true
truffle(development)> sca.then(function(instance){return instance.ownerCut()})
BigNumber { s: 1, e: 3, c: [ 2000 ] }

truffle(development)> myC.then(function(instance){return instance.totalSupply()})
BigNumber { s: 1, e: 0, c: [ 1 ] }
truffle(development)> myC.then(function(instance){return instance.ownerOf(0)})
'0x30753e4a8aad7f8597332e813735def5dd395028'
truffle(development)> myC.then(function(instance){return instance.ownerOf(1)})
'0x627306090abab3a6e1400e9345bc60c78a8bef57'
truffle(development)> myC.then(function(instance){return instance.getChan(0)})
[ 'AnimeGod',
  BigNumber { s: 1, e: 9, c: [ 1525245829 ] },
  BigNumber { s: 1, e: 0, c: [ 0 ] },
  true ]
truffle(development)> .exit

7. Create symlink from node_module to root Due to React.js' limitations, contracts outside of src directory must be symbolically linked from within node_module

cd build/contracts
npm link
cd ../..
npm link cryptochans

8. Run

npm run start

9.Mongodb: setup your local mongodb first in mongodb://localhost:27017 (if you use mac, use command "brew install mongodb") and then run "mongod" to start your local mongodb

then you can run "npm start" as usual, it will spawn off two processes running client and proxy server. Client will start fetching request using "fetch" to send to our proxy server(running on localhost:3001) Server will talk to mongodb and return back the db data to client. And then client can display the info on frontend.

In the future, we may change it to sql database(if the class server cannot support mongodb). But for now, we will just use mongodb.
