Run a full public node
```
./joystream-node \
--pruning archive
--ws-external
--rpc-external
--rpc-methods Safe
--rpc-cors all
--chain joy-mainnet
```

## Docker compose

```
services:

image: joystream/node:latest
command: >
--pruning archive
--ws-external
--rpc-external
--rpc-methods Safe
--rpc-cors all
--base-path /chain
--chain joy-mainnet
ports:
- "127.0.0.1:9944:9944" # Websocket JSON-RPC
- "127.0.0.1:9933:9933" # HTTP JSON-RPC
- 30333:30333
volumes:

## From source

## Test/Development node

To run a local development node remove the argument `--chain joy-mainnet` and replace it with `--dev`

# RPC interfaces on joystream node

The RPC nodes use JSON-RPC message protocol: https://www.jsonrpc.org/specification

RPC Call reference
https://polkadot.js.org/docs/api
https://polkadot.js.org/docs/substrate/rpc

RPC is available over two transports, Websocket and HTTP

## Websocket Transport - by default on port 9944
Local node: `ws://127.0.0.1:9944`
Public endpoint: wss://rpc.joystream.org

## HTTP Transport - by default on port 9933
Local node: `http://127.0.0.1:9933`
Public endpoint: https://http-rpc.joystream.org

# REST API - Sidecar

Public endpoints:

API Endpoint https://api-sidecar.joystream.org
API Docs https://docs-sidecar.joystream.org

## Running a local sidecar using public rpc endpoint

```
docker run --rm --read-only -e SAS_SUBSTRATE_URL=wss://rpc.joystream.org \
-p 8080:8080 parity/substrate-api-sidecar
```
