On application start-up: "TypeError: Cannot set property 'expose' of undefined"

It looks like you might be using an old version of express that doesn't expose the express app prototype that way that express-expose expects. If you upgrade to express 3 this should fix itself.

According to express-expose Readme.md, latest [email protected] is only compatible with [email protected]:

• [email protected] (use express-expose at >= 0.3.4)
• [email protected] (use express-expose at >= 0.2.3 and <= 0.3.3)
• [email protected] (use express-expose at <= 0.2.2)

Using the same patch version for different major releases of express seems like a violation of Semantic Versioning to me.

@lbeschastny pull request welcome

@niftylettuce I don't think that anything could be done about [email protected]/[email protected].

As for [email protected]/[email protected], you could re-release latest express-expose under 0.4.0 version, marking current [email protected] release as deprecated (or even unpublishing it). It'll resolve all versioning problems for [email protected] users.

As for pull-request, maintiners usually don't like contributors messing with package version, but if you want, I'll create one. Though, it'll be pointless without either deprecating or unpublishing current [email protected] release.
