'Node.js' addon wrapper ('NJSq')



  • GNU/Linux & OS X : Travis CI
  • Windows : AppVeyor


As each major version of Node.js (4, 5, 6…) has its own ABI which are incompatible with each other, a specific binary version of an Node.js addon has to be provided for each Node.js major version.

NJSq is a Node.js addon and, as hinted above, has to be compiled specifically for each major version of Node.js. But NJSq is only a wrapper to the true addons, which are dynamic libraries loaded by NJSq. This allows to compile this libraries only once, and the resulting binary can be used, with all version of Node.js, by using the dedicated NJSq binary .

Of course, regardless of the version of Node.js, both NJSq and the true addon dynamic library still have to match the platform (IA-32, AMD64, ARM…).

NJSq works with GNU/Linux (and probably other POSIX compliant operating systems), macOS and Windows, on IA-32, AMD64 and ARM (AArch32 and AArch64, like those on Raspberry Pi, Banana Pi, ODROID… devices) architectures.


You should not have to install NJSq explicitly, as it's only a wrapper which will be installed when needed, but you can by launching npm install njsq.

Under GNU/Linux (and other POSIX compliant systems, including macOS), you have a suitable development environment to be installed.

See also the compilation related page.


You should not have to modify the configuration file.
