This repo contains a client and a server, both written in TypeScript:
- **client**: React app setup with [squid-js](https://github.com/oceanprotocol/squid-js), bootstrapped with [Create React App](https://github.com/facebook/create-react-app)
- **server**: Node.js app, utilizing [Express](https://expressjs.com). The server provides various microservices, like remote file checking.
## 🏄 Get Started
To spin up both, the client and the server in a watch mode for local development, execute:
```bash
npm install
npm start
```
Open [http://localhost:3000](http://localhost:3000) to view the client in the browser. The page will reload if you make edits to files in either `./client` or `./server`.
To make use of all the functionality, you need to connect to the Ocean network. By default, the client will connect to [Ocean's Nile test network](https://docs.oceanprotocol.com/concepts/testnets/#the-nile-testnet) remotely.
### 🐳 Use with Barge
If you prefer to connect to locally running components instead of remote connections to Ocean's Nile network, you can spin up [`barge`](https://github.com/oceanprotocol/barge) and use a local network:
```bash
git clone git@github.com:oceanprotocol/barge.git
cd barge
./start_ocean.sh --latest --no-pleuston --local-spree-node
```
Modify `./client/src/config/config.ts` to use those local connections.
## 🛳 Production
To create a production build of both, the client and the server, run from the root of the project:
```bash
npm run build
```
Builds the client for production to the `./client/build` folder, and the server into the `./server/dist` folder.
## 👩🔬 Testing
```bash
npm test
```
Launches the test runner in the interactive watch mode.
## ✨ Code Style
For linting and auto-formatting you can use from the root of the project:
```bash
# auto format all ts & css with eslint & stylelint
npm run lint
# auto format all ts & css with prettier, taking all configs into account
npm run format
```
