#Import

import zlib from "nstdlib/zlib";

Note

Only the API surface is available. No compression binding, so every stream and one-shot throws ERR_NSTDLIB_NO_BINDING. The 154 exports and all of constants and codes are real and compared against the host builtin.

#Runtime support

Where it runs	Status	Export coverage	Details
nstd	⚠️ some support	–	3/64 of Node's own eligible tests pass under nstd.
Browser	❔ not tested	100% of Node.js	It imports with the small process shim. 154/154 Node.js exports are available. No module-specific behavior test ran.
Node.js (host)	⚠️ some support	100% of Node.js	154/154 exports.

#Exports (154 of 154)

Each cell shows what happens when code reads an export:

✅ Available through every import style. A named error also counts.
⚠️ Available through only some import styles.
❔ The export exists but has no value.
❌ The export does not exist.
– This environment was not measured.
