# Redux DevTools Command Line Interface

Bridge for remote debugging via [Redux DevTools extension](https://github.com/zalmoxisus/redux-devtools-extension), [Remote Redux DevTools](https://github.com/zalmoxisus/remote-redux-devtools) or [RemoteDev](https://github.com/zalmoxisus/remotedev).

### Usage

#### Install the package globally

with npm:

```
npm install -g redux-devtools-cli
```

or with yarn:

```
yarn global add redux-devtools-cli
```

and start as:

```
redux-devtools --hostname=localhost --port=8000
```

> Note the package is called `redux-devtools-cli` not `redux-devtools` (the latter is a React component).

#### Or add in your project

with npm:

```
npm install --save-dev redux-devtools-cli
```

or with yarn:

```
yarn add --dev redux-devtools-cli
```

and add to `package.json`:

```
"scripts": {
  "redux-devtools": "redux-devtools --hostname=localhost --port=8000"
}
```

So, you can start redux-devtools server by running `npm run redux-devtools`.

##### Import in your `server.js` script you use for starting a development server:

```js
var reduxDevTools = require('redux-devtools-cli');
reduxDevTools({ hostname: 'localhost', port: 8000 });
```

So, you can start redux-devtools server together with your dev server.

### Open Redux DevTools

You can add `--open` argument (or set it as `electron`) to open Redux DevTools as a standalone application:

```
redux-devtools --open
```

Set it as `browser` to open as a web app in the default browser instead:

```
redux-devtools --open=browser
```

To specify the browser:

```
redux-devtools --open=firefox
```

### Connection settings

Set `hostname` and `port` to the values you want. `hostname` by default is `localhost` and `port` is `8000`.

To use WSS, set `protocol` argument to `https` and provide `key`, `cert` and `passphrase` arguments.

#### Available options

### Inject to React Native local server

##### Add in your React Native app's `package.json`:

```
"scripts": {
  "redux-devtools": "redux-devtools --hostname=localhost --port=8000 --injectserver=reactnative"
}
```

The `injectserver` value can be `reactnative` or `macos` ([react-native-macos](https://github.com/ptmt/react-native-macos)), it used `reactnative` by default.

Then, we can start React Native server and Redux DevTools server with one command (`npm start`).

##### Revert the injection

Add in your React Native app's `package.json`:

```
"scripts": {
  "redux-devtools-revert": "redux-devtools --revert=reactnative"
}
```

Or just run `$(npm bin)/redux-devtools --revert`.

### Connect from Android device or emulator

> Note that if you're using `injectserver` argument explained above, this step is not necessary.

If you're running an Android 5.0+ device connected via USB or an Android emulator, use [adb command line tool](http://developer.android.com/tools/help/adb.html) to setup port forwarding from the device to your computer:

```
adb reverse tcp:8000 tcp:8000
```

If you're still use Android 4.0, you should use `10.0.2.2` (Genymotion: `10.0.3.2`) instead of `localhost` in [remote-redux-devtools](https://github.com/zalmoxisus/remote-redux-devtools#storeconfigurestorejs) or [remotedev](https://github.com/zalmoxisus/remotedev#usage).

### Save reports and logs

You can store reports via [`redux-remotedev`](https://github.com/zalmoxisus/redux-remotedev) and get them replicated with [Redux DevTools extension](https://github.com/zalmoxisus/redux-devtools-extension) or [Remote Redux DevTools](https://github.com/zalmoxisus/remote-redux-devtools). You can get action history right in the extension just by clicking the link from a report. Open `http://localhost:8000/graphiql` (assuming you're using `localhost` as host and `8000`) to explore in GraphQL. Reports are posted to `http://localhost:8000/`. See examples in [tests](https://github.com/zalmoxisus/remotedev-server/blob/937cfa1f0ac9dc12ebf7068eeaa8b03022ec33bc/test/integration.spec.js#L110-L165).

Redux DevTools server is database agnostic using `knex` schema. By default everything is stored in the memory using sqlite database. See [`defaultDbOptions.json`](https://github.com/reduxjs/redux-devtools/tree/master/packages/redux-devtools-cli/defaultDbOptions.json) for example of sqlite. You can replace `"connection": { "filename": ":memory:" },` with your file name (instead of `:memory:`) to persist teh database. Here's an example for PostgreSQL:

```
{
  "client": "pg",
  "connection": { "user": "myuser", "password": "mypassword", "database": "mydb" },
  "debug": false,
  "migrate": true
}
```
