node:assert

#Import

import assert from "nstdlib/node/assert";

Note

Behaves like Node.js.

#Support

node:assert. nstd: some support; Node test suite 35.7% passing. Browser: works; export coverage 100%; Node test suite 57.1% passing.

  • nstd: 5/14 of Node's own eligible tests pass under nstd.
  • Browser: Loads with a minimal process object. 21 of Node's 21 exports are available. 1 of 1 behavior checks match Node.js.

#Exports (21)

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: 21/21 of the host's export names answer inside host node. Behaviour verified against the host builtin.
  • smoke: Imports in a clean child process.
  • node-suite: 9/14 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.
