What are Reactors?
A Reactor is a serverless compute service allowing Node.js code hosted in Basis Theory to be executed against your tokens completely isolated away from your application and systems.
Reactors are invokable from any system that has the ability to make HTTPS requests and access the internet.
How It Works
Reactors are serverless function runtimes, similar to AWS Lambda, Azure Functions, or Cloudflare Workers - except your applications, systems, and infrastructure never touches the sensitive plaintext data.
