# Local development network

The local development network consists of following services:

* Local Acala Fork
* Eth Rpc Adapter
* \*Subquery Services
  * Postgres database
  * Subquery node
  * GraphQL engine

## Starting the stack

You can download or copy + paste this [docker compose file](https://github.com/AcalaNetwork/bodhi.js/blob/master/docker-compose.yml), and then

```
docker compose up
```

Once you see logs like this, the local development stack is ready.

```

This stack contains a local Acala fork, and an eth rpc adapter.

It does not contain a subquery services, since for local testing purpose, we usually do not need subquery services, and if you would like to setup a local subquery service, you can refer to the [subquery docs](https://github.com/AcalaNetwork/bodhi.js/tree/master/packages/evm-subql#run-with-docker).

{% hint style="info" %}
**In order to have a clean start after every shutdown of the node, run the following command after the node was shut down:**

**`docker compose down -v`**
{% endhint %}

## The local development network services

Once the local development network is up and running, the following services are available:

* A local mandala node: <ws://localhost:9944>
* \*A subquery service: <http://localhost:3001>
* An ETH JSON-RPC service:
  * <http://localhost:8545>
  * <ws://localhost:8545>
* Local network substrate chain explorer: [Polkadot.js App](https://polkadot.js.org/apps/?rpc=ws%3A%2F%2Flocalhost%3A9944%2Fws#/explorer)

You can now setup [Metamask on localhost](https://evmdocs.acala.network/tooling/metamask#localhost) and interact with your local setup, or try to deploy or interact with a smart contract.
