metabolizer v1.1.0

metabolizer

Express middleware to expose meta information

Usage

Can use the app.use() Express syntax to hook up metabolizer.

Example:

app.use('/version', require('metabolizer')(['name', 'version']));

This exposes the name and version properties in package.json to the "/version" route. If you hit <application URL>/version, you will get a JSON object with those values.

If you do not pass in a list, it will return just a version by default.

Notes

If you want to expose a value from package.json, prepend the variable name with npm_package_. For example, if you wanted the package version, use the environment variable npm_package_version.

The values are determined at runtime. If the value somehow changes after startup, metabolizer WILL NOT use the new value. This is to keep the (already trivial) performance hit even smaller.
