The standard Procfile format is supported by Nixpacks. However, only a single process is supported. The command specified in the Procfile will override the provider start command.

web: npm run start

Release process#

If a release process is found, a new phase is added that will run this command. The release phase will run after the build.

web: npm run start

# Will be run after the build phase
release: npm run migrate:deploy
