Kinsta automatically installs dependencies defined in your package.json file during the deployment process.
Kinsta automatically sets the PORT environment variable. You should not define it yourself and you should not hard-code it into the application.
When deploying an application, Kinsta automatically creates a web process with npm start as the entry point. Make sure to use this command to run your server.
Whenever a deployment is initiated (through creating an application or re-deploying due to an incoming commit) the npm build command is run, followed by the npm start command.
