This example uses the TypeScript SDK to build a small HTTP API. Each request gets a fresh sandbox, writes submitted code to /app/main.js, runs it with Node.js, returns the result, and destroys the sandbox.

​
Prerequisites

  • Node.js 18+.
  • A running StacyVM server.
  • Docker provider access on the StacyVM host.
  • A StacyVM API key if auth is enabled.
The source lives in examples/code-runner-typescript.

​
Install

cd examples/code-runner-typescript
npm install

​
Configure

export STACYVM_URL="http://localhost:7423"
export STACYVM_API_KEY="sk_test_YOUR_API_KEY"
export STACYVM_IMAGE="node:20"

​
Run The App

npm run dev

​
Submit Code

curl -sS -X POST http://localhost:8081/run-javascript \
  -H "Content-Type: application/json" \
  -d '{"code":"console.log([10, 20, 12].reduce((a, b) => a + b, 0));","timeout":"10s"}'

​
Response

{
  "exit_code": 0,
  "stdout": "42\n",
  "stderr": "",
  "duration": "120ms"
}

Production Notes

Before exposing this service, add authentication, request size limits, per-user quota attribution, audit logging, and host runtime certification.
