CasparCG to Node interface

Build Status

This project is early in development and API may change. The query, playout, data and template commands are mostly finished and I will be adding more as I need them. If you need something that is missing add an issue.

For now docs are in the source only.

Install

npm install caspar-cg

Usage Example

var CasparCG = require("caspar-cg");

ccg = new CasparCG("localhost", 5250);
ccg.connect(function () {
	ccg.info(function (err, serverInfo) {
		console.log(serverInfo);
	});

	ccg.play("1-1", "AMB");

	setTimeout(function () {
		ccg.clear("1");
		ccg.disconnect();
	}, 10 * 1000);
});

ccg.on("connected", function () {
	console.log("Connected");
});

Usage with Express and to render html5 templates

This code example requires express. The templates are rendered by using CALL and stringifying your json payload. The template on your caspar server can cast that string back to json.

	var express = require("express");
	var app = express();
	var router = express.Router();
	var path = __dirname + '/app/'; // source code directory
	var bodyParser = require("body-parser");

	var CasparCG = require("caspar-cg");
	ccg = new CasparCG("your-casparcg-ip-address", 5250);

	router.post("/caspar/:template",function(req,res){ // 
	  ccg.connect(function () {
	    var addCommand = 'CG 1-99 ADD 0 your-template-dir/'+req.params.template+' 1';
	    var updateCommand = 'CALL 1-99 UPDATE "'+JSON.stringify(req.body)+'"';
	    ccg.sendCommand(addCommand);
	    ccg.sendCommand(updateCommand, function(){
	      console.log('Command was sent')
	    })
	  });

	  res.send('Command was sent');
	});

	app.use(bodyParser.urlencoded({ extended: false }));
	app.use(bodyParser.json());

	app.use(express.static('node_modules'))
	app.use(express.static('app'))

	app.use("/",router);

	app.use("*",function(req,res){
	  res.sendFile(path + "404.html");
	});

	app.listen(3000,function(){
	  console.log("Live at Port 3000");
	});
