2. Setting up the development environment

There are a few technical requirements before we start. Please install the following:

Node.js 10.0.0
Npm - installed with Node.js

Developing and Running

Execute these commands in the project's root directory:

Download

git clone 'https://github.com/OntologyCommunityDevelopers/punica-ts.git'
cd punica-ts

Install dependencies

npm install

Build

This will build the project with minimum polyfilling for better debug experience.

npm run build

You will get the packaged code under '/lib'.

3. Global install without building

npm install punica-ts -g

4. Quickstart

To use most Punica commands, you need to run them against an existing Punica project. So the first step is to create a Punica project.

4.1. Create a Project

4.1.1. Initializing a New Project

You can create a bare Punica project with no smart contracts included, use punica-ts init command.

Once this operation is completed, you'll now have a project structure with the following items:

contracts/: Directory for Ontology smart contracts.
src/: Directory for DApp source file.
test/: Directory for test files for testing your application and contracts.
wallet/: Directory for save Ontology wallet file.

punica-ts init --help
Usage: init [options]
 
initialize new and empty Ontology DApp project
 
Options:
  -h, --help  output usage information

Note: If you not run punica cli in you project root directory, you need to use -p or --project option to specify your DApp project's path.

4.1.2. Creating a Box Project

You can create a bare project template, but for those just getting started, you can use Punica Boxes, which are example applications and project templates.

We'll use the ontology-tutorialtoken box, which creates a OEP4 token that can be transferred between accounts:

Create a new directory for your Punica project:

mkdir tutorialtoken
cd tutorialtoken

Download ("unbox") the MetaCoin box:

punica-ts unbox --box_name tutorialtoken

punica-ts unbox --help
Usage: unbox [options]
 
download a Punica Box, a pre-built Ontology DApp project.
 
Options:
  --box_name <BOX_NAME>  specify which box to unbox
  -h, --help             output usage information

Note:

You can use the punica-ts unbox --box_name <box-name> command to download any of the other Punica Boxes.
If you not run punica cli in you project root directory, you need to use -p or --project option to specify your DApp project's path.

4.2. Compiling

You can use the following command to compile your Ontology smart contracts:

punica-ts compile

If everything goes smoothly, you can find the avm and abi file in contracts/build folder.

contacts
    ├─build
    │      contract.avm
    │      contract_abi.json

For more usage, you can use punica-ts compile --help command.

punica-ts compile --help
Usage: compile [options]
 
compile the specified contracts to avm and abi files
 
Options:
  --contracts [CONTRACTS]  specify contracts files in contracts dir
  -h, --help               output usage information

Note: If you not run punica cli in you project root directory, you need to use -p or --project option to specify your DApp project's path.

4.3. Deployment

To deploy your contract, run the following:

punica-ts deploy

This will deploy your smart contract in build directory.

A simple deployment process looks like this:

Deploying...
Using network 'testNet'.
Running deployment: hello_ontology.avm
Contract has been deployed to address 0x24ed10357c6a6506297367f29ed80065a42a4625.

For more usage, you can use punica-ts deploy --help command.

punica-ts deploy --help
Usage: deploy [options]
 
deploy the specified contracts to specified chain
 
Options:
  --network [NETWORK]  specify which network the contracts will be deployed to
  --avm [AVM]          specify which avm file will be deployed
  --wallet [WALLET]    specify which wallet file will be used
  --config [CONFIG]    specify which deploy config file will be used
  -h, --help           output usage information

Note:

If you not run punica cli in you project root directory, you need to use -p or --project option to specify your DApp project's path.
If multi avm file exist in your build directory, you need to use --avm option to specify which contract you want to deploy.
If multi wallet file exist in your wallet directory, you may need to use --wallet option to specify which wallet you want to use. otherwise, a random wallet file in wallet directory will be used.

4.4. Invocation

If you want to invoke a list of function in your deployed smart contract, a convenience way is to use invoke command.

Suppose we have an invoke config in our default-config.json:

"invokeConfig":{
    "abi": "oep4_token_abi.json",
    "defaultPayer": "ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6",

                    },
                    {

                        "to": "ByteArray:Ad4H6AB3iY7gBGNukgBLgLiB6p3v627gz1",
                        "amount": 2
                    }
                ]
            },
            "signers": {
                "m": 1,
                "signer": ["ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6", "AazEvfQPcQ2GEFFPLF1ZLwQ7K5jDn81hve"]
            },
            "payer": "ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6",
            "preExec": false
        },
        {
        "name": "Allowance",
            "params": {
                "owner": "ByteArray:ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6",
                "spender": "ByteArray:AazEvfQPcQ2GEFFPLF1ZLwQ7K5jDn81hve"
            },
            "signers": {
                "m": 1,
                "signer": ["ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6"]
            },
            "preExec": false
        },
        {
        "name": "TransferFrom",
            "params": {
                "sender": "ByteArray:AazEvfQPcQ2GEFFPLF1ZLwQ7K5jDn81hve",
                "from_acct": "ByteArray:ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6",
                "to_acct": "ByteArray:Ad4H6AB3iY7gBGNukgBLgLiB6p3v627gz1",
                "amount": 1
            },
            "signers": {
                "m": 1,
                "signer": ["ANH5bHrrt111XwNEnuPZj6u95Dd6u7G4D6"]
            },
            "preExec": false
        },
        {
        "name": "Init",
            "params": {},
            "signers": {},
            "preExec": true
        }
    ]
}
