node:timers/promises

#Import

import timers_promises from "nstdlib/node/timers/promises";

Note

Behaves like Node.js. The same scheduler, compared against the host builtin.

#Support

node:timers/promises. nstd: works; Node test suite 84.8% passing. Browser: works; export coverage 100%; Node test suite 83.1% passing.

  • nstd: Gives the same output as Node.js in side-by-side tests: cold.
  • Browser: Loads with a minimal process object. 4 of Node's 4 exports are available. 1 of 1 behavior checks match Node.js.

#Exports (4)

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, undefined the other.
  • ❔ undefined both ways.
  • ❌ Not exported at all.
  • – Not measured.

#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: 4/4 of the host's export names answer inside host node. Behaviour verified against the host builtin. The same scheduler, compared against the host builtin.
  • smoke: Imports in a clean child process.
  • 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 (filed under timers, the parent module).
