# Chatangle Backend [](https://greenkeeper.io/) The backend for [Chatangle](https://github.com/pRizz/Chatangle); a free, decentralized, global chatroom, powered by the IOTA tangle. # Installation Instructions ## General Installation For global installation: ```bash npm install -g chatangle-backend ``` This will make Chatangle Backend available as the command `chatangle-backend`. ### Installation Errors If you get errors during install about bad permissions, your `npm` was probably installed as the root user. It is recommended to install `npm` as non-root, like with `nvm`. A workaround is to install with the `--unsafe-perm` flag like so: ```bash npm install -g --unsafe-perm chatangle-backend ``` # Usage You must have a working [IOTA Transaction Stream](https://github.com/pRizz/IOTA-Transaction-Stream). If globally installed, example: ```bash chatangle-backend --iotaTransactionStreamIP 123.45.67.890 --iotaTransactionStreamPort 8008 --isIotaTransactionStreamSecured false --webSocketServerPort 8008 ``` If installed locally or running from an IDE: ```bash npm run start -- --iotaTransactionStreamIP 123.45.67.890 --iotaTransactionStreamPort 8008 --isIotaTransactionStreamSecured false --webSocketServerPort 8008 ``` Running in the background, example: ```bash nohup --iotaTransactionStreamIP 123.45.67.890 --iotaTransactionStreamPort 8008 --isIotaTransactionStreamSecured false --webSocketServerPort 8008 >> output.log & ``` Then tail the logs with ```bash tail -f output.log ``` If `PORT` is specified in the environment, this will override `webSocketServerPort` ### Hooking Into The Backend These lines of Javascript can be copy-pasted into the Chrome console after starting the server locally to test if the backend is working: ```Javascript let ws = new WebSocket('ws://chatangleBackendIP:8008') ws.addEventListener('message', message => {console.log('message', message)}) ws.addEventListener('error', message => {console.error('error', message)}) ws.addEventListener('open', message => {console.log('open', message)}) ```
