npm package: @meowcoin-foundation/meowcoin-rpc
Description: Helps you access your Meowcoin full node using RPC from JavaScript
Author: Zach Price
Latest version: 0.4.0

# meowcoin-rpc

A package that will help you do RPC calls from Node.js to your Meowcoin core node, that is your full Meowcoin node.

URLs for locally installed Meowcoin nodes.

- http://127.0.0.1:8766 for mainnet
- http://127.0.0.1:18766 for testnet

Meowcoin as a service, you don't need your own node

- https://mewc-rpc-mainnet.mewccrypto.com/rpc for mainnet
- https://tls-rpc-testnet.ting.finance/rpc for testnet

# Install

```
npm install @meowcoin-foundation/meowcoin-rpc
```

# Example using ES modules

This example uses Meowcoin as a service from https://rpc.ting.finance.

In node.js you need to give the file the ending .mjs for modular JavaScript.
Like `example.mjs`

```
import { getRPC, methods } from "@meowcoin-foundation/meowcoin-rpc";

const username = "anonymous";
const password = "anonymous";
const URL = "https://mewc-rpc-mainnet.mewccrypto.com/rpc";
const rpc = getRPC(username, password, URL);

const params = [];
rpc(methods.getblockcount, params).then(console.log);
```

# Example using CommonJS

```

const { getRPC, methods } = require("@meowcoin-foundation/meowcoin-rpc");
//methods is a list of all available methods/functions/commands/procedures

const rpc = getRPC("UsernameSecret", "PasswordSecret", "http://localhost:8766");

const promise = rpc(methods.getassetdata, ["ELVIS"]);
promise.catch((e) => {
  console.dir(e);
});

promise.then((response) => {
  console.log(response);
});


```

will print out

```
{ name: 'ELVIS', amount: 1, units: 8, reissuable: 1, has_ipfs: 0 }
```

## Example list all generated addresses in a Wallet (Meowcoin core)

Use method `listreceivedbyaddress` to receive a list of all generated addresses.
Write the result to a .json file

```
const { getRPC, methods } = require("@meowcoin-foundation/meowcoin-rpc");
//methods is a list of all available methods/functions/commands/procedures

const method = methods.listreceivedbyaddress;
const minConfirmations = 1;
const includeEmpty = true;

const params = [minConfirmations, includeEmpty];

const rpc = getRPC("UsernameSecret", "PasswordSecret", "http://localhost:8766");

const promise = rpc(method, params);
promise.catch((e) => {
  console.dir(e);
});

promise.then((response) => {
  const addresses = [];
  response.map(function (obj) {
    addresses.push(obj.address);
  });
  writeToFile(addresses);
  console.log("DONE, check out addresses.json");
});

function writeToFile(list){
    const json = JSON.stringify(list, null, 4);
    require("fs").writeFileSync("./addresses.json", json);

}

```

# Methods / commands / Procedure calls

Here is a list of all method/commands [All methods](meowcoin_methods.md)

In your local Meowcoin core wallet, you can go to

help > debug window > console

type `help`
..and you get a list of all available commands
