If your Node.js version is 4.4.7, you need the Node.js connector provided in the latest field test. If you have a WRC login, you can find it under "developer download". Be aware this is a field test version - not ready for production use.

The existing versions you'll find in the latest official release (2016.1) are cache0100.node (for Node.js version 0.10.x) and cache0120.node (for version 0.12.x). If you install a on a 64-bit Windows, you also need to install the Node.js 64-bit binary and use the corresponding 64-bit cache.node connector you'll find in the Caché bin directory - as Caché follows the OS architecture version, everything needs to be of the same architecture version - Node.js itself and also the cache.node connector. Just put the connector in your node_modules directory (where you install your other Node.js modules using npm) and rename it to cache.node, that's all! You then just put require('cache') in your Javascript code and you can open a Caché connection.

If you need the cache.node connector for the current Node.js LTS version 4.x from the field test, you don't need to install the Caché field test completely - you can also extract it from the field test installation package (cache-2016.3.0.640.0-win_x64.exe) using e.g. 7-Zip: first extract the field test installer exe to a temp dir and next, also extract the other_~1.cab file in the temp dir to another temp dir. You'll find there a cache421.node connector you can use with Node.js version 4.x (currently v4.5.0).

One more tip: to determine if a certain cacheXXXX.node connector version will work with your Node.js version, you can check the Node.js release table: you need to look at the NODE_MODULE_VERSION column. As long as the module version number is the same, it will work with that Node.js version. E.g. in the field test installer, you'll find a cache421.node connector for version 4.2.1. As this is module version 46, it will also work on Node.js 4.4.7 and 4.5.0. But it will not work on version 6.x (module version 48 is required for that).

And in addition, always remember the OS architecture (x86 or x64) needs to be the same for Caché, Node.js and the cache.node connector!

Hi Stephan, that's really great news! Is there any progress on the npm release of the Node.js connector?

Currently I need to use the field test connector version in my production environment (!) because I need the Node.js 4.x version - many npm modules already require a much more recent Node.js version 4 to install. In the latest official 2016.1 release there is only a v0.10 and a v0.12 connector available.

Thanks in advance!
