    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()) { ... }
