# 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/)
