For some strange reason, Browserify will hardcode absolute paths from the machine that generated the bundle to be able to resolve `__dirname` and `__filename` calls. This makes no sense, given that it means that the Browserify bundle will not work when we move it to another machine, which went undetected probably for months. The Browserify community apparently makes modules to fix this particular issue (like `bundle-collapser`, and `intreq`), however none of this seem to solve the problem for the Etcher CLI bundle. I also gave https://github.com/zeit/pkg a go, however I gave up after not being able to make use of native modules (nothing seems to work; the packager result will simply not find the addons). Finally, I ended up making the following workarounds: - Edit the Browserify bundle file to use its own `__dirname` to dynamically resolve the values of `__dirname` and `__filename` of the files it contains - Patch `lzma-native` to statically require its add-on rather than relying on dynamic requires from `node-pre-gyp`, which makes it impossible to resolve on the final bundle See: https://github.com/resin-io/etcher/issues/355 See: http://stackoverflow.com/questions/21993073/browserify-with-paths-to-folders-in-my-system Signed-off-by: Juan Cruz Viotti <jviotti@openmailbox.org>
