# fabric-network-simple
A simplified wrapper for fabric-network. Typescript usage is recommended for auto config checks.
## Installation
```
npm install fabric-network-simple
yarn add fabric-network-simple
```
##Include
```typescript
import fabricNetworkSimple from "fabric-network-simple";
```
## Configuration
fabric-network-simple reads configurations from a config object as an argument in function initGateway
Example Configuration
```typescript
const config: fabricNetworkSimple.config = {
channelName: "test-channel",
contractName: "test-contract",
connectionProfile: {
name: "Network",
version: "1.1",
channels: {
"test-channel": {

## Usage
Say we have a query function "set", and invoke function "get" that gets/sets a number to a variable on the chaincode
```typescript
//constructor
const fabricNetwork =
new fabricNetworkSimple(
config //config object, see example config section
);
//sets variable to 5
const invokeResult =
await fabricNetwork.invokeChaincode(
'set', //chaincode method
[5], //arguments
{} //transient data
);
//gets variable from ledger
const queryResult =
await fabricNetwork.queryChaincode(
'get', //chaincode method
[] //arguments
);
console.log('queryResult'); //prints 5
```
