Examples

instanceVarDir returns the absolute path to the instance’s folder on the server, e.g. /usr/local/neolane/nl6/var/instance1. Use it to build file paths instead of hardcoding them, so the same script runs unchanged across instances and environments. For the upload subfolder specifically, prefer 📕 instanceUploadDir.

It is available as a read-only string on the application singleton, set by the deployment and not changeable from script.

Build a path under the instance folder

Create path for temporary or working files to the var folder rather than an absolute path:

var rejectFile = application.instanceVarDir + "/" + getUUID() + ".csv"; // /usr/local/neolane/nl6/var/instance1/3f2a...csv

In a workflow attribute

when used in a workflow activity:

<%= application.instanceVarDir %>/<%= [email protected]() %>_<%= formatDate(new Date(), "%4Y%2M%2D") %>.csv

Unit tests

Tested with acc by running acc instance exec -f test/integration/instanceVarDir.spec.js in a sandbox: 

loadLibrary("/nl/core/shared/nl.js"); // import NL.assert
context.test1 = NL.assert(typeof application.instanceVarDir === "string");
context.test2 = NL.assert(application.instanceVarDir.length > 0);
