Getting started

$3

``
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:

`javascript
const { CasparCG } = require('casparcg-connection')

const connection = new CasparCG()
const { error, request } = await connection.play({ channel: 1, layer: 1, clip: 'amb' })
if (error) {
console.log('Error when sending', error)
} else {
const response = await request
console.log(response)
}
`

_Note: as of 6.0.0 the library has had a major rewrite with significant API changes and support for CasparCG 2.0 was dropped._

Installing with yarn adds the dev-dependencies needed to compile TypeScript. A set of commands help you managing development and testing:

- yarn clean Empties the /dist directory.
- yarn build Runs a single build command without watching for changes.
- yarn build -w Rebuilds on every change.
- yarn lint Runs code linting. Pull Requests won't be accepted without lint compliance.
- yarn test Runs code tests through Jest.

Doing a release

* Run yarn changelog` to generate the changelog, tags and commit.
* Push these changes and the newly made tag.
* Trigger a run of the Publish to NPM workflow in GitHub Actions.
