Sails: When using Sails ≤ v0.12: file uploads displaying deprecation warning about "os.tmpDir()"

[sanjaykumarns]

Sails version: 0.12.14
Node version: v9.4.0
NPM version: 5.6.0
DB adapter name: N/A
DB adapter version: N/A
Operating system: Debian GNU/Linux 8 (jessie)

I am trying to implement file upload api in sailsjs (Followed this), but the DeprecationWarning is showing while dealing with file type.

(node:23566) [DEP0022] DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead.

Sailsjs version: 0.12.14

I have solved the deprecated warning by changing the 55th line in node_modules/sails/node_modules/skipper/node_modules/multiparty/index.js

from self.uploadDir = options.uploadDir || os.tmpDir(); to self.uploadDir = options.uploadDir || os.tmpdir();
But it is not a good solution as we are ignoring these node_modules folders while pushing into git and moving into production servers.

The question is available in stack overflow also:

@sanjaykumarns thanks for posting. We must have sorted this out in a subsequent release of Skipper, because I haven't seen it myself and we've been doing a lot of file upload work recently. But we're also using the current LTS version of Node (v8.x).

Would you mind trying this out in your app on Node 8, just to verify that this is a Node 9-only problem? If you're also seeing it on Node 8, then something else must be going on

@mikermcneil I see the same behaviour myself with my own application under Node 8.12.0 and Sails 0.12.4 on macOS 10.13.6 and was able to replicate it with a super-simple app as well: https://github.com/VirtualWolf/sails-file-upload-test

@sanjaykumarns @VirtualWolf - Thanks for all the help so far and sharing the examples. I see there are newer versions of Node 8 LTS (8.16.0) and Node 9 (9.11.2) that may help resolve this issue - has anyone seen any improvement after updating?

[VirtualWolf]

@johnabrams7 Just tested and it still occurs with both 8.16.0 and 9.11.2. (I'm now on macOS 10.14.4 if that matters).

@VirtualWolf Thanks for that! (updated issue title accordingly)

@sanjaykumarns @VirtualWolf You know, I suspect what might have happened is that this deprecation warning started appearing with a different Node version we were developing with when working with our last remaining Sails v0.12 app last year.

Since this is just a warning, and since its no longer an issue in Sails v1, let's triage any further action on this. If anyone notices this occurring in Sails v1.0 or later though, please drop a comment in here -- I will definitely address that if it comes up.

Thanks again to you both!
