CasparCG is an open source graphics- and video server for broadcast and streaming productions. This library lets you connect and interact with CasparCG servers from Node.js in Javascript.

• CasparCG AMCP 2.0 and 2.1 protocol implemented
• Parsing and validation of command parameters and response
• Queueing of commands
• Promise-based commands for easy chaining and sequences
• Helper functions for parsing of Config, Version and System info

• Node.js
• npm package
• TypeScript/Javascript, strongly typed
• ES5 target, easily compiled to ES2015 (ES6) or higher for more modern syntax as described here
• Linted with standard ESLint rules (TSLint)
• API Docs
• Getting started guide
• MIT license

npm install casparcg-connection --save

This installs the full project with sourcecode and dependencies, typescript project files and the compiled .js output with typings.

In your code, include and use the CasparCG object from this library with a code similar to:

const {CasparCG} = require("casparcg-connection");

var connection = new CasparCG();
connection.play(1, 1, "amb");

Note: starting with version 4.0.0 the default queue mode is now SALVO. You can optionally set the queue mode back to sequential if you need compatibility with CasparCG 2.0.7 or earlier. Note that the implementation of scheduled commands requires asynchronous behaviour and therefore only works in salvo mode.

Installing from NPM adds the dev-dependencies needed to compile TypeScript and using Gulp as build tool. A set of commands help you managing development and testing:

• npm run gulp Runs the build command and watches all /src files for changes, re-running the build upon each file change.
• npm run clean Empties the /js directory.
• npm run build Runs a single build command without watching for changes.
• npm run cleanBuild Runs the clean command before a build command.
• npm run lint Runs code linting. Pull Requests won't be accepted without lint compliance.
• npm run test Runs code tests through Jasmine.
