node:timers
#Import
import timers from "nstdlib/node/timers";Note
Behaves like Node.js. Scheduled on the host setTimeout. ref()/unref() reach the host timer handle, and process.nextTick is installed only into a realm that has none. A host that already has one keeps it.
#Support
- nstd: 50/59 of Node's own eligible tests pass under nstd.
- Browser: Loads with a minimal
processobject. 7 of Node's 7 exports are available. 1 of 1 behavior checks match Node.js.
#Exports (7)
Every name Node.js exports from this module, and what you get when you read it, as a named import or as a property of the default import:
- ✅ A value, both ways. An export that throws an error naming the missing feature also counts.
- ⚠️ A value one way,
undefinedthe other. - ❔
undefinedboth ways. - ❌ Not exported at all.
- – Not measured.
| Export | Node.js | Browser |
|---|---|---|
clearImmediate | ✅ | ✅ |
clearInterval | ✅ | ✅ |
clearTimeout | ✅ | ✅ |
promises | ✅ | ✅ |
setImmediate | ✅ | ✅ |
setInterval | ✅ | ✅ |
setTimeout | ✅ | ✅ |
#Diagnostics
nstdlib running inside Node.js. This isn't an environment it's meant for, so it isn't shown above, but it tells a library problem from an environment one:
coverage: 7/7 of the host's export names answer inside host node. Behaviour verified against the host builtin. Scheduled on the hostsetTimeout.ref()/unref()reach the host timer handle, andprocess.nextTickis installed only into a realm that has none. A host that already has one keeps it.smoke: Imports in a clean child process.vitest: Test/runtime/timers.test.ts: 46/46 assertions pass.node-suite: 52/59 of Node's own eligible tests pass with ./dist inside host node. A failure there and in the page is the library's, one only in the page is the engine's.
