## Introduction

ThunderHub is an **open-source** LND node manager where you can manage and monitor your node on any device or browser. It allows you to take control of the lightning network with a simple and intuitive UX and the most up-to-date tech stack.

---

### Integrations

**BTCPay Server**
ThunderHub is currently integrated into BTCPay for easier deployment. If you already have a BTCPay server and want to add ThunderHub or even want to start a BTCPay server from zero, be sure to check out this [tutorial](https://apotdevin.com/blog/thunderhub-btcpay)

**Raspiblitz**
For Raspiblitz users you can also get ThunderHub running by following this [gist](https://gist.github.com/openoms/8ba963915c786ce01892f2c9fa2707bc)

---

### Tech Stack

This repository consists of a **NextJS** server that handles both the backend **Graphql Server** and the frontend **React App**. ThunderHub connects to your Lightning Network node by using the gRPC ports.

- NextJS
- ReactJS
- Typescript
- Styled-Components
- Apollo
- Apollo-Server
- GraphQL

## **Requirements**

- Yarn/npm installed
- Node installed (Version 12.16.0 or higher)

**Older Versions of Node**
Earlier versions of Node can be used if you replace the following commands:

```js
//Yarn
yarn start -> yarn start:compatible
yarn dev -> yarn dev:compatible

//NPM
npm start -> npm start:compatible
npm run dev -> npm run dev:compatible
```

**HodlHodl integration will not work with older versions of Node!**

---

## Config

You can define some environment variables that ThunderHub can start with. To do this create a `.env` file in the root directory with the following parameters:

```bash
# -----------
# Server Configs
# -----------
LOG_LEVEL = 'error' | 'warn' | 'info' | 'http' | 'verbose' | 'debug' | 'silly' //Default: 'info'
HODL_KEY = '[Key provided by HodlHodl]' //Default: ''
BASE_PATH = '[Base path where you want to have thunderhub running i.e. '/btcpay']' //Default: '/'

# -----------
# Interface Configs
# -----------
THEME = 'dark' | 'light'; // Default: 'dark'
CURRENCY = 'sat' | 'btc' | 'eur' | 'usd'; // Default: 'sat'

# -----------
# Privacy Configs
# -----------
FETCH_PRICES = true | false // Default: true
FETCH_FEES = true | false // Default: true
HODL_HODL = true | false // Default: true
DISABLE_LINKS = true | false // Default: false
NO_CLIENT_ACCOUNTS = true | false // Default: false
NO_VERSION_CHECK = true | false // Default: false
```

### SSO Account

You can define an account to work with SSO cookie authentication by adding the following parameters in the `.env` file:

```bash
# -----------
# SSO Account Configs
# -----------
COOKIE_PATH = '/path/to/cookie/file/.cookie'; // i.e. '/data/.cookie'
SSO_SERVER_URL = 'url and port to node'; // i.e. '127.0.0.1:10009'
SSO_CERT_PATH = '/path/to/tls/certificate'; // i.e. '\lnd\alice\tls.cert'
SSO_MACAROON_PATH = '/path/to/macaroon/folder'; //i.e. '\lnd\alice\data\chain\bitcoin\regtest\'
```

To login to this account you must add the cookie file content to the end of your ThunderHub url. For example:

```
http://localhost:3000?token=[COOKIE]
```

Replace `[COOKIE]` with the contents of the `.cookie` file.

### Server Accounts

You can add accounts on the server by adding this parameter to the `.env` file:

```bash
# -----------
# Account Configs
# -----------
ACCOUNT_CONFIG_PATH = '/path/to/config/file.yaml'; // i.e. '/data/thubConfig.yaml'
```

You must also add a YAML file at that location with the following format:

```yaml
masterPassword: 'password' # Default password unless defined in account
accounts:
  - name: 'Account 1'
    serverUrl: 'url:port'
    macaroonPath: '/path/to/admin.macaroon'
    certificatePath: '/path/to/tls.cert'
    password: 'password for account 1'
  - name: 'Account 2'
    serverUrl: 'url:port'
    macaroonPath: '/path/to/admin.macaroon'
    certificatePath: '/path/to/tls.cert'
    # password: Leave without password and it will use the master password
```

### Privacy Configs

**Prices and Fees**
ThunderHub fetches fiat prices from [Blockchain.com](https://blockchain.info/ticker)'s api and bitcoin on chain fees from [Earn.com](https://bitcoinfees.earn.com/api/v1/fees/recommended)'s api.

If you want to deactivate these requests you can set `FETCH_PRICES=false` and `FETCH_FEES=false` in your `.env` file or manually change them inside the settings view of ThunderHub.

**Links**
ThunderHub shows you links for quick viewing of nodes by public key on [1ml.com](https://1ml.com/) and for viewing onchain transactions on [Blockchain.com](https://www.blockchain.com/).

If you don't want to show these links, you can set `DISABLE_LINKS=true` in your `.env` file.

**HodlHodl**
ThunderHub has a HodlHodl integration to view offers from this platform.

If you want to disable this integration, you can set `HODL_HODL=false` in your `.env` file.

**Client Accounts**
ThunderHub allows you to create accounts on the browser which are also encrypted and stored in the same browser.

If you want to disable this option and only allow accounts that are created on the server, you can set `NO_CLIENT_ACCOUNTS=true` in your `.env` file.

**Version Check**
ThunderHub gets the latest available version from [Github](https://api.github.com/repos/apotdevin/thunderhub/releases/latest) and shows you a message if you are on an older version.

If you want to disable this option you can set `NO_VERSION_CHECK=true` in your `.env` file.

### Running on different base path

Adding a BASE_PATH will run the ThunderHub server on a different base path.
For example:

- default base path of `/` runs ThunderHub on `http://localhost:3000`
- base path of `/thub` runs ThunderHub on `http://localhost:3000/thub`

To run on a base path, ThunderHub needs to be behind a proxy with the following configuration (NGINX example):

```nginx
location /thub/ {
  rewrite ^/thub(.*)$ $1 break;
  proxy_pass http://localhost:3000/;
}
```

---

## Installation

To run ThunderHub you first need to clone this repository.

```js
git clone https://github.com/apotdevin/thunderhub.git
```

After cloning the repository run `yarn` or `npm install` to get all the necessary modules installed.

After all the dependencies have finished installing, you can proceed to build and run the app with the following commands.

```javascript
// Yarn
yarn build
yarn start

// NPM
npm run build
npm start
```

This will start the server on port 3000, so just go to `localhost:3000` to see the app running.

If you want to specify a different port (for example port `4000`) run with:

```js
// Yarn
yarn start -p 4000

// NPM
npm start -- -p 4000
```

---

## Updating

There are multiple ways to update ThunderHub to it's latest version.

_Commands have to be called inside the thunderhub repository folder._

**1. Script Shortcut**

```sh
// Yarn
yarn update

// NPM
npm run update
```

**2. Script**

```sh
sh ./scripts/updateToLatest.sh
```

**3. Step by Step**

```sh
// Yarn
git pull
yarn
yarn build

// NPM
git pull
npm install
npm run build
```

**Then you can start your server:**

```sh
// Yarn
yarn start

// NPM
npm run start
```

## Development

If you want to develop on ThunderHub and want hot reloading when you do changes, use the following commands:

```js
//Yarn
yarn dev

//NPM
npm run dev
```

---

## Docker

ThunderHub also provides docker images for easier deployment. [Docker Hub](https://hub.docker.com/repository/docker/apotdevin/thunderhub)

To get ThunderHub running with docker follow these steps:

1. `docker pull apotdevin/thunderhub:v0.5.5` (Or the latest version you find)
2. `docker run --rm -it -p 3000:3000/tcp apotdevin/thunderhub:v0.5.5`

You can now go to `localhost:3000` to see your running instance of ThunderHub
