# MyEtherWallet
MyEtherWallet (v4+)

#### Run:

```bash
npm run dev # run app in dev mode
```

#### Build:

```bash
npm run build # build app
```

It generates app in `dist` folder.

#### Test:

```bash
npm run test # run tests with Jest
```

## Docker setup
You should already have docker and docker-compose setup for your platform as a pre-req.

```bash
docker-compose up
```

## Style Guides and Philosophies

The following are guides for developers to follow for writing compliant code.

### Styling

Legacy styles are housed under `common/assets/styles` and written with LESS.
However, going forward, each styled component should create a a `.scss` file of
the same name in the same folder, and import it like so:

```js
import React from "react";

import "./MyComponent.scss";

export default class MyComponent extends React.component {
	render() {
		return (
			<div className="MyComponent">
				<div className="MyComponent-child">Hello!</div>
			</div>
		);
	}
}
```

These style modules adhere to [SuitCSS naming convention](https://github.com/suitcss/suit/blob/master/doc/naming-conventions.md):

```scss
.MyComponent {
	/* Styles */

	&-child {
		/* Styles */

		&.is-hidden {
			display: none;
		}
	}
}
```

All elements inside of a component should extend its parent class namespace, or
create a new namespace (Potentially breaking that out into its own component.)

Variables and mixins can be imported from the files in `common/styles`:

```scss
@import "sass/colors";

code {
	color: $code-color;
}
```

#### Converting Styles

When working on a module that has styling in Less, try to do the following:

* Screenshot the component in question
* Create a new SCSS file in the same directory
* Remove styling from LESS file, convert it to the SCSS file (Mostly s/@/$)
* Convert class names to SuitCSS naming convention
* Convert any utility classes from `etherewallet-utilities.less` into mixins
* Convert as many element selectors to class name selectors as possible
* Convert as many `<br/>` tags or `&nbsp;`s to margins
* Ensure that there has been little to no deviation from screenshot
