subspace - react example
===
Simple application using a react observable component to receive a stream of emitted events. This app will deploy a test contract to **Ganache**.
## Requirements
- `ganache-cli`
- `yarn` or `npm` installed.
## Install
In the parent folder, link the package with `yarn` or `npm`
```
yarn link
```
Then in the current folder link `@status-im/subspace`, and install the packages
```
yarn link "@status-im/subspace"
yarn
```
## Usage
In a terminal execute
```
ganache-cli
```
In a different session, execute
```
yarn run start
```
Browse the DApp in [http://localhost:3000](http://localhost:3000)
*Note*: this is a simple example application that does not include error handling for the web3 connection. Be sure `ganache-cli` is running in `localhost:8545` before browsing the dapp.
