cec-client based Typescript API
Makes it possible for you to monitor incomming cec messages and send them, using a consistent promise-based API.
This library makes it trivially easy to start supporting CEC-Remote events and the like for most TV sets. it supports
- Easily send commands to CEC-enabled devices using a ready made library.
- Promise-based API, where applicable.
- TypeScript provides intellisense/type-completion for the entire library.
- Only two node dependencies.
Features that are currently half implemented or coming to this library are:
- Helper classes for the Television and Receiever commands: Planning to make it easier to send commands to tvs and stereos without knowledge of the CEC protocol.
- More command functions in the Commander class: make it easier for beginners to send commands to any device on the cec-bus.
- Expand examples.
- Add introduction to HDMI-CEC docs.
In order to start using this example, you need to have the cec-client app installed, and (preferably) in your $PATH. Some pointers on common devices:
On recent Raspberry PI images (jessie+) cec-client is installed by default, with the exception of really bare-minimum images.
If you do need to install it (e.g.
cec-client -h gives you an error), you can install it using (with a working internet connection):
sudo apt-get updatesudo apt-get install cec-utils
Simple remote application:
;// Create a new Remote helper (called without any arguments, it will create a cec-client process itself, with the default client name);// When any button is pressed on the remote, we receive the event:remote.on'keypress',;// Alternatively, we only wait for the user to press the "select" keyremote.on'keypress.select',;
var cecRemote = Remote;// Create a new Remote helper (called without any arguments, it will create a cec-client process itself, with the default client name)var remote = ;// When any button is pressed on the remote, we receive the event:remote;// Alternatively, we only wait for the user to press the "select" keyremote;
