Introduction
inject-glob
is a simple wrapper around nject and glob.
glob provides a mechanism to traverse a directory structure and
'find' files for injection to create a dependency injection tree.
Installation
%> npm install inject-glob --save
Usage
This is the basic usage. In this usage, where all options are defaulted, the names are derived from file names, no aggregation of any of the injectables is done, and the default globs are used.
path = require('path')
di = require('inject-glob')
di(null, (err, resolved) -> resolved.app.start())
For reference, here are the defaults, where the function injectName
simply
removes the extension of a file and uses the file name for the name of the
injectable:
defaults =
globs : [ '**/*.js', '**/*.coffee', '**/*.json' ]
cwd : '.'
interceptName : (f) -> injectName(f)
aggregateOn : ->
A possibly more complete and detailed version might look like the following.
In this example everything in the app/model
directory is aggregated on to
resolved.model
. The name of the default.json file is mapped to config
and so provided on resolved.config
and injected in functions which need
those value with the normal mechanism module.exports = (config) ->
.
path = require('path')
di = require('inject-glob')
opts =
globs : [ '**/*.js', '**/*.coffee', '**/*.json' ]
cwd : 'app/'
aggregateOn : (name) ->
switch (path.dirname(name))
when 'app/model' then { aggregateOn: 'model' }
else undefined
interceptName : (name, injectName) ->
switch (name)
when 'config/default.json' then 'config'
else injectName(name)
di(null, (err, resolved) -> resolved.app.start())
