subspace - react graphql example
|
||||
===
|
||||
Simple application using graphql queries to receive a stream of events
|
||||
This app will deploy a test contract to **Ganache**.
|
||||
|
||||
## Requirements
|
||||
- `ganache-cli`
|
||||
- `yarn` or `npm` installed.
|
||||
|
||||
## Install
|
||||
In the parent folder, install, build and link the package with `yarn` or `npm`
|
||||
```
|
||||
yarn
|
||||
yarn build:dev
|
||||
yarn link
|
||||
```
|
||||
Then in the current folder link `@embarklabs/subspace`, and install the packages
|
||||
```
|
||||
yarn link "@embarklabs/subspace"
|
||||
yarn
|
||||
```
|
||||
|
||||
## Usage
|
||||
In a terminal execute
|
||||
```
|
||||
ganache-cli
|
||||
```
|
||||
|
||||
In a different session, execute
|
||||
|
||||
```
|
||||
yarn run deploy
|
||||
```
|
||||
|
||||
And then:
|
||||
|
||||
```
|
||||
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.

### node-gyp problems
|
||||
node-gyp can cause problems, because it requires a C++ compiler.
|
||||
|
||||
If you do have problems caused by it, first follow the installation steps for your OS [here](https://github.com/nodejs/node-gyp#installation).
|
||||
|
||||
If you still have problems and are on Windows, try the following:
|
||||
- run `npm config set msvs_version 2015` before `npm install`
|
||||
- Repair Windows Build tools that the node-gyp doc made you install. If it tells you to remove a conflicting version do it. After the repair succeeded, reboot.
