# Ethereum Lite Explorer

Use the [Ethereum Lite Explorer](https://lite-explorer.aleth.io/) to explore blockchain data at the block, transaction, 
and account level.
 
The Ethereum Lite Explorer is a client-side only web application that connects to any Ethereum 
JSON RPC enabled node. No server, hosting, or trusting third parties to display the blockchain data is 
required. 

!!! note 
     The Ethereum Lite Explorer is an [Alethio product](https://aleth.io/).

## Prerequisites

[Docker](https://docs.docker.com/install/) or [npm](https://www.npmjs.com/get-npm)

## Run Using Docker

To run the Lite Explorer using the Docker image: 

1. Start Pantheon with the [`--rpc-http-enabled`](../Reference/Pantheon-CLI-Syntax.md#rpc-http-enabled) option. 

    !!! example 
        
        To run Pantheon in development mode:
        
        ```bash
        pantheon --network=dev --miner-enabled --miner-coinbase=0xfe3b557e8fb62b89f4916b721be55ceb828dbd73 --rpc-http-cors-origins="all" --host-whitelist="all" --rpc-http-enabled --data-path=/tmp/tmpDatdir
        ```

1. Run the `alethio/ethereum-lite-explorer` Docker image specifying the RPC HTTP URL (`http://localhost:8545` in this example): 

    ```bash
    docker run -p 80:80 -e NODE_URL=http://localhost:8545 alethio/ethereum-lite-explorer
    ```

1. Open [localhost](http://localhost) in your browser to view the Lite Explorer. 

## Install and Run 

1. Clone the `ethereum-lite-explorer` repository: 
   
    ```bash
    git clone https://github.com/Alethio/ethereum-lite-explorer.git
    ```

1. Change into the `ethereum-lite-explorer` directory: 
   ```bash
   cd ethereum-lite-explorer
   ```

1. Install npm packages: 

    ```bash
    npm install
    ```

1. Copy the sample config: 

    ```bash 
    cp config.default.json config.dev.json
    ```
  
1. Update the `config.dev.json` file: 

    * Set `APP_NODE_URL` to the RPC HTTP URL of your node (`http://localhost:8545` in this example)
   
    * Remove other environment variables. 
   
1. In another terminal, start Pantheon with the [`--rpc-http-enabled`](../Reference/Pantheon-CLI-Syntax.md#rpc-http-enabled) option. 

    !!! example 
        
        To run Pantheon in development mode:
        
        ```bash
        pantheon --network=dev --miner-enabled --miner-coinbase=0xfe3b557e8fb62b89f4916b721be55ceb828dbd73 --rpc-http-cors-origins="all" --host-whitelist="all" --rpc-http-enabled --data-path=/tmp/tmpDatdir
        ```
        
1. In the `ethereum-lite-explorer` directory, run the Lite Explorer in development mode: 

    ```bash
    npm run build
    npm run start
    ```  
   
1. A browser windows should open displaying the Ethereum Lite Explorer (http://localhost:3000/)
