## π Get Started
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.
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`.
### π Remote Ocean: Nile
To make use of all the functionality, you need to connect to the Ocean network. By default, the client will connect to Ocean components running within [Ocean's Nile test network](https://docs.oceanprotocol.com/concepts/testnets/#the-nile-testnet) remotely.
This means you need to connect with your MetaMask to the Nile network too. To do this:
1. select Custom RPC in the network dropdown in MetaMask
2. under New Network, enter `https://nile.dev-ocean.com` as the custom RPC URL
3. Hit _Save_, and youβre now connected to Nile
### π³ 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.ts` to use those local connections.
## π©βπ¬ Testing
Test suite is setup with [Jest](https://jestjs.io) and [react-testing-library](https://github.com/kentcdodds/react-testing-library).
To run all tests, including all linting tests:
```bash
npm test
```
For local development, you can start the test runners for client & server in a watch mode.
```bash
npm run test:watch
```
This will work for daily development but it misses the full interactivity of the test runner. If you need that, you will need to run them in individual terminal sessions:
```bash
cd client/
npm run test:watch
cd server/
npm run test:watch
```
## β¨ 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
```
## π³ 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.
## β¬οΈ Releases
Running any release task does the following:
- bumps the project version
- creates a Git tag
- updates CHANGELOG.md file with commit messages
- commits and pushes everything
- creates a GitHub release with commit messages as description
You can execute the script using {major|minor|patch} as first argument to bump the version accordingly:
- To bump a patch version: `npm run release`
- To bump a minor version: `npm run release-minor`
- To bump a major version: `npm run release-major`
By creating the Git tag with these tasks, Travis will trigger a new Kubernetes deployment automatically aftr a successful tag build.
For the GitHub releases steps a GitHub personal access token, exported as `GITHUB_TOKEN` is required. [Setup](https://github.com/release-it/release-it#github-releases)
