# @kodex-data/evm-prototypes

The `@kodex-data/evm-prototypes` package provides a set of utility functions and prototypes for working with Ethereum Virtual Machine (EVM) data types such as strings, addresses, and numbers.

## Installation

You can install the package using `yarn` or `npm`:

```bash
yarn add @kodex-data/evm-prototypes 
# or
npm install @kodex-data/evm-prototypes
```

## Usage

Once installed, you can import the package in your TypeScript code as follows:

```typescript
import '@kodex-data/evm-prototypes'
```

This will extend the `String` and `Number` prototypes with additional methods, as shown below.

```ts
declare global {
    interface String {
        strip0x(): string;
        isHex(): boolean;
        toHex(): string;
        fromHex(): string;
        toAscii(): string;
        isAddress(): boolean;
        isEtherAddress(): boolean;
        addrIsEqual(address: string): boolean;
        toChecksumAddress(): string;
        isKeccakHash(): boolean;
        trimAddress(): string;
        findHex(): string[];
        findHex(type: 'address'): string[];
        findHex(type: 'keccak'): string[];
        toSha3(): string;
        toUtf8Bytes(): Uint8Array;
        isNumber(): boolean;
        toUint(add0x?: boolean): string;
        isValidJSON(): boolean;
        isTwitterUrl(): boolean;
        getTwitterUsername(): string | undefined;
        rndHex(l?: number): string;
    }
    interface Number {
        toUint(add0x?: boolean): string;
        toHex(): string;
        isOdd(): boolean;
    }
}

declare global {
    interface String {
        toBN(base?: number): BigNumber;
        shiftedBy(n: number): string;
        shiftedBy(n: number, asBN: undefined | false | null): string;
        shiftedBy(n: number, asBN: true): BigNumber;
    }
    interface Number {
        toBN(): BigNumber;
        toUint(add0x?: boolean): string;
        shiftedBy(n: number): string;
        shiftedBy(n: number, asBN: boolean): BigNumber;
        noExponents(): string;
    }
}
```
