# Example with React + Typescript + Webpack 5 + MUI
An example of using default Webpack and Typescript settings with React and MUI, including theming.
You can use this example as a seed for a new project.
Remember to build the dependency packages from the root of this repo by running:
```
yarn
yarn build
```
If you need to make changes to the dependency packages, you can run `yarn watch` in that package to watch for chagnes and build them. This project will pick up the changes in the built package and hot-reload / recompile.
## Features
### Yarn workspaces
Packages from `ts-packages` are shared using Yarn workspaces. Make sure you add you new project to [package.json](../../package.json) to use the shared packages.
> ⚠️ **Warning**: Yarn workspaces will share all dependencies between projects and works by falling back to parent directories until a `node_modules` directory is found. So be careful when messing around with `node_modules` and resolution, because unexpected things could happen - for example, if you do not run `yarn` from the root and you have a `node_modules` in a directory that is a parent of the directory where you checkout out this repository, that `node_modules` will be used for resolving packages 🙀.
### Typescript
Shared Typescript config is in [tsconfig.json](./tsconfig.json), with specific production settings in [tsconfig.prod.json](./tsconfig.prod.json) that:
- exclude Storybook stories and Jest tests
- do not output typing `*.d.ts` files
### Webpack
Inherit config for Webpack 5 with additional tweaks including:
- favicon generation from [favicon asset files](../../assets/favicon/favicon.png)
- asset handling (svg, png, fonts, css, etc)
- minification
The development settings include:
- `ts-loader` for quick transpilation
- threaded type checking using `tsc`
- hot reloading using `react-refresh`
### Storybook
Storybook is available in [@nymproject/react](../react-components/src/stories/Introduction.stories.mdx) and can be run using `yarn storybook`.
### MUI and theming
The [Nym theme](../mui-theme/src/theme/theme.ts) provides a theme provider that you can add as follows:
```typescript jsx
export const App: React.FC = () => (
);
export const AppTheme: React.FC = ({ children }) => {
const { mode } = useAppContext();
return {children};
};
export const Content: React.FC = () => {
...
}
```
And augment typings for the Theme by adding [mui-theme.d.ts](./src/theme/mui-theme.d.ts):
```typescript
import { Theme, ThemeOptions, Palette, PaletteOptions } from '@mui/material/styles';
import { NymTheme, NymPaletteWithExtensions, NymPaletteWithExtensionsOptions } from '@nymproject/mui-theme';
declare module '@mui/material/styles' {
interface Theme extends NymTheme {}
interface ThemeOptions extends Partial {}
interface Palette extends NymPaletteWithExtensions {}
interface PaletteOptions extends NymPaletteWithExtensionsOptions {}
}
```
Adding the above, means that any component now has the correct typings, for example, below the Nym palette interface is available for all MUI `Theme` instances with code completion for VSCode and IntelliJ:
```typescript jsx
import { Typography } from '@mui/material';
...
theme.palette.nym.networkExplorer.mixnodes.status.active }}>
The quick brown fox jumps over the white fence
```
