There is an overview of all parts of palava.tv at [palavatv/palava](https://github.com/palavatv/palava).\n\nThe signal tower is a signaling server for WebRTC applications written in Elixir. It implements the [palava signaling protocol][palava protocol] over websockets to be used together with the [palava client][palava client].\n\n## Setup\n\n**Install:**\n```\nmix deps.get\nmix deps.compile\n```\n\n**Test:**\n```\nmix test\n```\n\nYou can also watch file changes and rerun tests automatically:\n\n```\nmix test.watch\n```\n\n**Start locally:**\n```\n./start.sh or ./start_daemon.sh\n```\n\n**Release and use in production:**\n```\nmix release production\n```\n\n**Options:**\n\nTo use a Turn Server, generate a secret key string, e.g. via `openssl rand -base64 30` and set:\n```\nexport SIGNALTOWER_TURN_SECRET=\u003cgenerated_secret_key\u003e\n```\nThe same secret key must be configured in the turn server.\nFor example for coturn, use the following configuration in turnserver.conf:\n```\nuse-auth-secret\nstatic-auth-secret=\u003cgenerated_secret_key\u003e\n```\n\nBy default, the websocket port 4233 is used, you can change it via:\n```\nexport SIGNALTOWER_PORT=1234\n```\n\nBy default, the websocket is bound to all interfaces (0.0.0.0), you can also bind it just localhost (127.0.0.1) via:\n```\nexport SIGNALTOWER_LOCALHOST\n```\n\n## References\n\n[palava protocol]: https://github.com/palavatv/palava-client/wiki/Protocol\n[palava client]: https://github.com/palavatv/palava-client/\n[palava project]: https://github.com/palavatv/palava\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpalavatv%2Fsignaltower","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpalavatv%2Fsignaltower","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpalavatv%2Fsignaltower/lists"}
