npm WARN minimatch deprecated

[vikramdurai]

While installing dependencies I find that minimatch an a few other things are deprecated:

npm WARN deprecated babel@6.5.2: Babel's CLI commands have been moved from the babel package to the babel-cli package
npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated graceful-fs@1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs@^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
npm WARN deprecated to-iso-string@0.0.2: to-iso-string has been deprecated, use @segment/to-iso-string instead.
npm WARN deprecated jade@0.26.3: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

Is this a problem with socket.io, express or is it (self)?

Now it's fixed, but something else appears:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.0.15:
 wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

You can mostly ignore warnings since they don't break code. Also, we have no control over sub-dependencies, so we can't do much to fix these.
