The app is a React app built with [Gatsby.js](https://www.gatsbyjs.org) + TypeScript + CSS modules and will connect to Ocean components in Rinkeby by default.
If you prefer to connect to locally running components instead of remote connections, you can spin up [`barge`](https://github.com/oceanprotocol/barge) and use a local Ganache network in another terminal before running `npm start`:
The `app.config.js` file is setup to prioritize environment variables for setting each Ocean component endpoint. By setting environment variables, you can easily switch between Ocean networks the app connects to, without directly modifying `app.config.js`.
[Storybook](https://storybook.js.org) is set up for this project and is used for UI development of components. Stories are created inside `src/components/` alongside each component in the form of `ComponentName.stories.tsx`.
To run the Storybook server, execute in your Terminal:
```bash
npm run storybook
```
This will launch the Storybook UI with all stories loaded under [localhost:4000](http://localhost:4000).
## ✨ Code Style
For linting and auto-formatting you can use from the root of the project:
```bash
# lint all js with eslint
npm run lint
# auto format all js & css with prettier, taking all configs into account
npm run format
```
## 👩🔬 Testing
Test suite for unit tests is setup with [Jest](https://jestjs.io) as a test runner and:
- [react-testing-library](https://github.com/kentcdodds/react-testing-library) for all React components
To run all linting and unit tests:
```bash
npm test
```
For local development, you can start the test runner in a watch mode.
```bash
npm run test:watch
```
For analyzing the generated JavaScript bundle sizes you can use:
```bash
npm run analyze
```
## 🛳 Production
