Control Flow

retry, when, and forEach — alineo's built-in workflow control-flow primitives.

control-flow

Demonstrates all of alineo's built-in workflow control-flow primitives in a single sandbox.

bunx alineo-cli init   # starts OpenSandbox in Docker (one-time setup)

bun install
bun start

Primitive	Description
`retry`	Retries a flaky command up to 5 times with exponential backoff
`when`	Branches conditionally based on the previous exec's exit code
`forEach`	Iterates over a list, running a command per item

Exposing Ports

Start an HTTP server inside a sandbox and reach it from the host via sb.proxy().
