# BTC RPC Explorer

[![npm version][npm-ver-img]][npm-ver-url] [![NPM downloads][npm-dl-img]][npm-dl-url]


Simple, database-free Bitcoin blockchain explorer, via RPC. Built with Node.js, express, bootstrap-v4.

This tool is intended to be a simple, self-hosted explorer for the Bitcoin blockchain, driven by RPC calls to your own bitcoind node. This tool is easy to run but currently lacks features compared to database-backed explorers.

Whatever reasons one might have for running a full node (trustlessness, technical curiosity, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can not only explore the blockchain (in the traditional sense of the term "explorer"), but also explore the functional capabilities of your own node.

# Getting started

The below instructions are geared toward BTC, but can be adapted easily to other coins.

## Prerequisites

1. Install and run a full, archiving node - [instructions](https://bitcoin.org/en/full-node). Ensure that your bitcoin node has full transaction indexing enabled (`txindex=1`) and the RPC server enabled (`server=1`).
2. Synchronize your node with the Bitcoin network.
3. "Recent" version of Node.js (8+ recommended).

## Instructions

```bash
npm install -g btc-rpc-explorer
btc-rpc-explorer
```

If you're running on mainnet with the default datadir and port, this Should Just Work.
Open [http://127.0.0.1:3002/](http://127.0.0.1:3002/) to view the explorer.

You may set configuration options in a `.env` file or using CLI args.
See [configuration](#configuration) for details.

### Configuration

Configuration options may be passed as environment variables
or by creating an env file at `~/.config/btc-rpc-explorer.env`
or at `.env` in the working directory.
See [.env-sample](.env-sample) for a list of the options and details for formatting `.env`.

You may also pass options as CLI arguments, for example:

```bash
btc-rpc-explorer --port 8080 --bitcoind-port 18443 --bitcoind-cookie ~/.bitcoin/regtest/.cookie
```

See `btc-rpc-explorer --help` for the full list of CLI options.

## Run via Docker

1. `docker build -t btc-rpc-explorer .`
2. `docker run -p 3002:3002 -it btc-rpc-explorer`
