The Dynatrace JS runtime is a server-side AppEngine sandbox that executes JavaScript/TypeScript.
Function contract
Every entry point must export a default async function:
export default async function () {
// ...
return result;
}
ES module syntax required. TypeScript accepted (type annotations, interfaces, generics). No other export shape is supported.
References
Start here, then load only the file you need.
| File | When to load |
|------|-------------|
| references/limits-and-restrictions.md | Timeout / memory / I/O quotas; what's forbidden (eval, WebSocket, sockets, filesystem) |
| references/apis-and-modules.md | Which Web APIs and Node.js compat modules are available (fetch, crypto, streams, buffer, …) |
| references/fetch.md | Calling internal /platform/... APIs or external URLs, credential vault, outbound allowlist |
| references/sdk.md | Any @dynatrace-sdk/* package — the index routes you to the right per-SDK file |
Running a function with dtctl
Use dtctl exec function to run JS runtime code without deploying an app.
# Run inline code
dtctl exec function --code 'export default async function() { return "hello" }'
# Run from file
dtctl exec function -f script.js
# Pass JSON input — accessed as event.payload inside the function
dtctl exec function -f script.js --payload '{"key":"value"}'
The function may accept an optional event parameter:
export default async function(event) {
const { payload } = event; // from --payload
// event.environmentId also available
return payload;
}
Load the dynatrace-control skill for authentication setup, context switching, and the full exec function reference.
