@scramjet/adapter-process

Process adapter for Transform Hub. Runs Sequences as child processes on the host machine using Node.js, Bun, or Python runners.

When to use

The process adapter is the default adapter for Transform Hub. It is suitable for development, testing, and production deployments where each Sequence runs as a dedicated OS process on the same machine as the Hub. No Docker or Kubernetes infrastructure is required.

The adapter is selected via the --runtime-adapter process flag or the adapters configuration. It provides:

• ProcessSequenceAdapter — manages sequence storage and retrieval
• ProcessInstanceAdapter — manages instance lifecycle as child processes

Configuration

The process adapter is configured through STH configuration and does not require additional setup beyond ensuring the runtimes (Node.js, Bun, Python) are available on the host.

scramjet-transform-hub --runtime-adapter process

Stability

This package is stable. The process adapter is the default and most-tested adapter.
