Electron support

[ghost]

I'm building an electron (v1.4.15) app with webpack and want to use bunyan for logging. After adding the proper aliases I run into a error TypeError: dtrace.createDTraceProvider is not a function. If I block out dtrace-provider in my webpack config, everything goes according to plan but webpack throws the can't resolve warning:

WARNING in ./packages/mrtl-desktop/~/bunyan/lib/bunyan.js
Module not found: Error: Can't resolve 'dtrace-provider' in 'C:\..\mrtl-desktop\node_modules\bunyan\lib'
 @ ./packages/mrtl-desktop/~/bunyan/lib/bunyan.js 79:17-48

I've resorted to adding new IgnorePlugin(/dtrace-provider/) in my config which resolves the error, but I'm not sure if this is the best solution........

Running into a maybe related issue?. However even disabling in config doesn't seem to solve it for me. :-/ Electron 1.6.0

I've never played with Electron, so I'm not sure what mechanisms are there that would be appropriate. Help from others appreciated.

If it helps: The dtrace-provider module is an optional part of bunyan. It'll behave just fine without it. It'll just mean that you can't use dtrace and bunyan -p ... to inspect logging of the app at runtime (on platforms that support dtrace -- smartos/illumos/solaris, bsd, and Mac to a degree).

[justechn]

npm install --no-optional gets rid of the error

[sumitkm]

Just to elaborate on @justechn If you have bunyan installed already, uninstall it from your project

npm uninstall bunyan --save

Then install it with the no-optional flag.

npm install bunyan --save --no-optional

I tried to compile the dtrace module only, for electron using electron's provided steps, but it complains about missing gyp config file. @trentm unless you are in a position to fix the dtrace 'node-gyp' config issue, I would close this with the solution being install without dtrace (and ofcourse thanks for bunyan 💯 ).

Here is the error I get when following Electron's suggested steps

I am not familiar enough with the node-gyp/electron-gyp tool-chain to help any further :(
