# MyEtherWallet V4+ (ALPHA - VISIT [V3](https://github.com/kvhnuke/etherwallet) for the production site)
|
|
|
|
#### 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
|
|
```
|
|
|
|
#### Dev (HTTPS):
|
|
|
|
1. Create your own SSL Certificate (Heroku has a [nice guide here](https://devcenter.heroku.com/articles/ssl-certificate-self))
|
|
2. Move the `.key` and `.crt` files into `webpack_config/server.*`
|
|
3. Run the following command:
|
|
|
|
```bash
|
|
npm run dev:https
|
|
```
|
|
|
|
#### Derivation Check:
|
|
##### The derivation checker utility assumes that you have:
|
|
1. Docker installed/available
|
|
2. [dternyak/eth-priv-to-addr](https://hub.docker.com/r/dternyak/eth-priv-to-addr/) pulled from DockerHub
|
|
|
|
##### Docker setup instructions:
|
|
1. Install docker (on macOS, [Docker for Mac](https://docs.docker.com/docker-for-mac/)is suggested)
|
|
2. `docker pull dternyak/eth-priv-to-addr`
|
|
|
|
##### Run Derivation Checker
|
|
```bash
|
|
npm run derivation-checker
|
|
```
|
|
|
|

## Style Guides and Philosophies
|
|
|
|
The following are guides for developers to follow for writing compliant code.
|
|
|
|
|
|
### Redux and Actions
|
|
|
|
Each reducer has one file in `reducers/[namespace].ts` that contains the reducer
|
|
and initial state, one file in `actions/[namespace].ts` that contains the action
|
|
creators and their return types, and optionally one file in
|
|
`sagas/[namespace].ts` that handles action side effects using
|
|
[`redux-saga`](https://github.com/redux-saga/redux-saga).
|
|
|
|
The files should be laid out as follows:
|
|
|
|
#### Reducer
|
|
|
|
* State should be explicitly defined and exported
|
|
* Initial state should match state typing, define every key
|
|
|
|
```ts
|
|
import { NamespaceAction } from "actions/[namespace]";
|
|
import { TypeKeys } from 'actions/[namespace]/constants';
|
|
|
|
export interface State { /* definition for state object */ };
|
|
export const INITIAL_STATE: State = { /* Initial state shape */ };
|
|
|
|
export function [namespace](
|
|
state: State = INITIAL_STATE,
|
|
action: NamespaceAction
|
|
): State {
|
|
switch (action.type) {
|
|
case TypeKeys.NAMESPACE_NAME_OF_ACTION:
|
|
return {
|
|
...state,
|
|
// Alterations to state
|
|
};
|
|
default:
|
|
return state;
|
|
}
|
|
}
|
|
```
|
|
|
|
#### Actions
|
|
* Define each action creator in `actionCreator.ts`
|
|
* Define each action object type in `actionTypes.ts`
|
|
* Export a union of all of the action types for use by the reducer
|
|
* Define each action type as a string enum in `constants.ts`
|
|
* Export `actionCreators` and `actionTypes` from module file `index.ts`
|
|
|
|
```
|
|
├── common
|
|
├── actions - application actions
|
|
├── [namespace] - action namespace
|
|
├── actionCreators.ts - action creators
|
|
├── actionTypes.ts - action interfaces / types
|
|
├── constants.ts - string enum
|
|
├── index.ts - exports all action creators and action object types
|
|
```
|
|
##### constants.ts
|
|
```ts
|
|
export enum TypeKeys {
|
|
NAMESPACE_NAME_OF_ACTION = 'NAMESPACE_NAME_OF_ACTION'
|
|
}
|
|
```
|
|
##### actionTypes.ts
|
|
```ts
|
|
/*** Name of action ***/
|
|
export interface NameOfActionAction {
|
|
type: TypeKeys.NAMESPACE_NAME_OF_ACTION,
|
|
/* Rest of the action object shape */
|
|
};
|
|
|
|
/*** Action Union ***/
|
|
export type NamespaceAction =
|
|
| ActionOneAction
|
|
| ActionTwoAction
|
|
| ActionThreeAction;
|
|
```
|
|
##### actionCreators.ts
|
|
```ts
|
|
import * as interfaces from './actionTypes';
|
|
import { TypeKeys } from './constants';
|
|
|
|
export interface TNameOfAction = typeof nameOfAction;
|
|
export function nameOfAction(): interfaces.NameOfActionAction {
|
|
return {
|
|
type: TypeKeys.NAMESPACE_NAME_OF_ACTION,
|
|
payload: {}
|
|
};
|
|
};
|
|
```
|
|
##### index.ts
|
|
```ts
|
|
export * from './actionCreators';
|
|
export * from './actionTypes';
|
|
```
|
|
### Higher Order Components
|
|
|
|
#### Typing Injected Props
|
|
Props made available through higher order components can be tricky to type. Normally, if a component requires a prop, you add it to the component's interface and it just works. However, working with injected props from [higher order components](https://medium.com/@franleplant/react-higher-order-components-in-depth-cf9032ee6c3e), you will be forced to supply all required props whenever you compose the component.
|
|
|
|
```
|
|
interface MyComponentProps {
|
|
name: string;
|
|
countryCode?: string;
|
|
router: InjectedRouter;
|
|
}
|
|
|
|
...
|
|
|
|
class OtherComponent extends React.Component<{}, {}> {
|
|
render() {
|
|
return (
|
|
<MyComponent
|
|
name="foo"
|
|
countryCode="CA"
|
|
// Error: 'router' is missing!
|
|
/>
|
|
);
|
|
}
|
|
```
|
|
|
|
Instead of tacking the injected props on to the MyComponentProps interface itself, put them on another interface that extends the main interface:
|
|
|
|
```
|
|
interface MyComponentProps {
|
|
name: string;
|
|
countryCode?: string;
|
|
}
|
|
|
|
interface InjectedProps extends MyComponentProps {
|
|
router: InjectedRouter;
|
|
}
|
|
```
|
|
|
|
Now you can add a [getter](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) to the component to derive the injected props from the props object at runtime:
|
|
|
|
```
|
|
class MyComponent extends React.Component<MyComponentProps, {}> {
|
|
get injected() {
|
|
return this.props as InjectedProps;
|
|
}
|
|
|
|
render() {
|
|
const { name, countryCode } = this.props;
|
|
const { router } = this.injected;
|
|
...
|
|
}
|
|
}
|
|
```
|
|
|
|
All the injected props are now strongly typed, while staying private to the module, and not polluting the public props interface.
|
|
|
|
### 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:
|
|
|
|
```ts
|
|
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 ` `s to margins
|
|
* Ensure that there has been little to no deviation from screenshot
|
