cfenv 1.0.0 with new getServiceCreds() method

I've updated the node.js cfenv package at npm:

  • moved from the netherworld of 0.x.y versioned packages to version 1.0.0
  • updated some of the package dependencies
  • added a new appEnv.getServiceCreds(spec) method

In case you're not familiar with the cfenv package, it's intended to be the swiss army knife of handling your Cloud Foundry runtime environment variables, including: PORT, VCAP_SERVICES, and VCAP_APPLICATION.

Here's a quick example that doesn't including accessing services in VCAP_SERVICES:

You can start your server with this kind of snippet, which provides the correct port, binding address, and url of the running server; and it will run locally as well as on CloudFoundry.

Lately I've been finding myself just needing the credentials property value from service objects. To make this just a little bit easier than:

you can now do this, using the new appEnv.getServiceCreds(spec) API:

No need to get the whole service if you don't need it, and you don't have to type out credentials all the time :-)

what else?

What other gadgets does cfenv need? If you have thoughts, don't hesitate to open an issue, send a pull request, etc.
