About

Abi-wan-kanabi is an UNLICENSE standalone TypeScript parser for Cairo smart contracts. It enables on the fly typechecking and autocompletion for contracts call directly in typescript. Developers can now catch typing mistakes early, prior to executing the call on-chain, and thus enhancing the overall Dapp development experience.

Getting Started

Prerequisites

Abiwan is a standalone typescript library. Its only dependence is on typescript version 4.9.5 or higher. Also, it makes use of BigInt, so the tsconfig.json should target at least ES2020:

// tsconfig.json
{
  "compilerOptions": {
    "target": "ES2020",                         
    "lib": ["ES2020", "ESNext"],
  }
}

Build

To use abiwan, you must first generate types from your contracts' ABI json files, for example using the helper script (deprecated):

./scripts/extract_abi.sh <path>/<to>/<abi>.json <path>/<to>/<other_abi>.json ./

This will create a declaration file (.d.ts) for the abi. You can then import it in any script and you are set to go:

import abi from './abi_demo.ts'
import {call} from './kannabi.ts'
call(abi, "balance_of", 5n);

If you think that we should be able to import types directly from the json files, we think so too! See this typescript issue and thumb it up!

Warning

Abiwan is still very young and has not yet been subject to an official release. We do not recommand using it in production yet.
