## README

# massa-sc-utils
Various utils for easily building smart contract

### Requirements

* NodeJS 14+
* npm / yarn (see package.json)

### Package commands

1. Run `yarn install` to install all deps
2. Run `yarn run build` to build distribution content
3. Run `yarn run test` to run integration and unit tests

### Smart contract utilities

The library provides methods for compiling smart contracts written in AssemblyScript with TypeScript, either via CLI or on the fly. With both methods, the returned values are a text, a binary and a base64 representation of the WASM.

Examples are shown below:

```ts
const SMART_CONTRACT_EXAMPLE = `export function add(x: number, y: number): number { return x+y };`;

const utils = new SmartContractUtils();

// compile smart contract from a typescript file with assemblycode
const compiledScFromSource: CompiledSmartContract = await utils.compileSmartContractFromSourceFile({
    smartContractFilePath: "helloworld.ts",
} as WasmConfig);

// compile smart contract from a .wasm file
const compiledScFromFile: CompiledSmartContract = await utils.compileSmartContractFromWasmFile("helloworld.wasm");

// compile smart contract on the fly
const compiledScFromString: CompiledSmartContract = await utils.compileSmartContractFromString(SMART_CONTRACT_EXAMPLE);
```
