Source

detect-libc

Node.js module to detect details of the C standard library (libc) implementation provided by a given Linux system.

Currently supports detection of GNU glibc and MUSL libc.

Provides asychronous and synchronous functions for the family (e.g. glibc, musl) and version (e.g. 1.23, 1.2.3).

For previous v1.x releases, please see the v1 branch.

Install

npm install detect-libc

API

GLIBC

const GLIBC: string = 'glibc';

A String constant containing the value glibc.

MUSL

const MUSL: string = 'musl';

A String constant containing the value musl.

family

function family(): Promise<string | null>;

Resolves asychronously with:

  • glibc or musl when the libc family can be determined
  • null when the libc family cannot be determined
  • null when run on a non-Linux platform
const { family, GLIBC, MUSL } = require('detect-libc'); switch (await family()) { case GLIBC: ... case MUSL: ... case null: ... }

familySync

function familySync(): string | null;

Synchronous version of family().

const { familySync, GLIBC, MUSL } = require('detect-libc'); switch (familySync()) { case GLIBC: ... case MUSL: ... case null: ... }

version

function version(): Promise<string | null>;

Resolves asychronously with:

  • The version when it can be determined
  • null when the libc family cannot be determined
  • null when run on a non-Linux platform
const { version } = require('detect-libc'); const v = await version(); if (v) { const [major, minor, patch] = v.split('.'); }

versionSync

function versionSync(): string | null;

Synchronous version of version().

const { versionSync } = require('detect-libc'); const v = versionSync(); if (v) { const [major, minor, patch] = v.split('.'); }

isNonGlibcLinux

function isNonGlibcLinux(): Promise<boolean>;

Resolves asychronously with:

  • false when the libc family is glibc
  • true when the libc family is not glibc
  • false when run on a non-Linux platform
const { isNonGlibcLinux } = require('detect-libc'); if (await isNonGlibcLinux()) { ... }

isNonGlibcLinuxSync

function isNonGlibcLinuxSync(): boolean;

Synchronous version of isNonGlibcLinux().

const { isNonGlibcLinuxSync } = require('detect-libc'); if (isNonGlibcLinuxSync()) { ... }
