npm install prod
Easily perform a kitchen sink of asynchronous operations on each item in a module's dependency tree.
Put individual names and versions of all dependencies in some db by walking over the tree using an async .map:
``js
var prod = require('prod')
var moduleRoot = path.dirname(require.resolve('tape'))
prod(moduleRoot).map(function (dep, next) {
db.put(dep.name + '@' + dep.version, next)
}, function(err, deps) {
if (err) throw err
console.log(deps)
// => [
// 'tape@2.0.0',
// 'jsonify@0.0.0',
// 'deep-equal@0.1.0',
// 'defined@0.0.0',
// 'through@2.3.4'
// ]
})
})
`
`js
// pass any module's root directory to walk over it and it's dependencies
var tapeDependencies = prod(path.dirname(require.resolve('tape')))
var myDependencies = prod() // defaults to process.cwd()
Object.keys(myDependencies) // => // each, eachSeries, eachLimit, map, ...etc.
// See below.
`
prod uses timoxley/async-mixin, so you automatically have access to the following
methods from caolin/async while iterating over your dependency tree:
* each
* eachSeries
* eachLimit
* map
* mapSeries
* mapLimit
* filter
* filterSeries
* reject
* rejectSeries
* reduce
* reduceRight
* detect
* detectSeries
* sortBy
* some
* every
* concat
* concatSeries
If you don't want any of this async magic, you can simply initialize
prod with .load and use regular Array operations on its .dependencies
`js
var myDependencies = prod().load(function(err, dependencies) {
if (err) throw err
console.log(dependencies === myDependencies.dependencies) // => true
// regular ES5 Array methods
dependencies.map(function(dep) {
return dep.name
})
})
``
Alternatively, you could try using read-installed
with traverse
