expand-target
Expand target definitions in a declarative configuration.
Install
Install with npm:
$ npm install --save expand-target
Usage
var target = require('expand-target');
Write declarative "target" definitions similar in concept to those used by grunt and make. This is useful for shared configs or to dynamically build-up a configuration that can be passed to any build system (even gulp!).
Basic example
target({
files: {
'a/': ['*.js'],
'b/': ['*.js'],
'c/': ['*.js']
}
});
results in
{
files: [
{
src: ['examples.js', 'index.js'],
dest: 'a/'
},
{
src: ['examples.js', 'index.js'],
dest: 'b/'
},
{
src: ['examples.js', 'index.js'],
dest: 'c/'
}
]
}
the same example with
expand: true
defined on the options
target({
options: { expand: true },
files: {
'a/': ['*.js'],
'b/': ['*.js'],
'c/': ['*.js']
}
});
results in
{
options: {
expand: true
},
files: [
{
src: ['examples.js'],
dest: 'a/examples.js'
},
{
src: ['index.js'],
dest: 'a/index.js'
},
{
src: ['examples.js'],
dest: 'b/examples.js'
},
{
src: ['index.js'],
dest: 'b/index.js'
},
{
src: ['examples.js'],
dest: 'c/examples.js'
},
{
src: ['index.js'],
dest: 'c/index.js'
}
]
}

Plugins
Plugins must be registered before the configuration is expanded, which means you need to use the expand
method instead of passing your config directly to the constructor.
var target = new Target({cwd: 'foo'});
target
.use(foo)
.use(bar)
.use(baz);
target.expand({
src: '*.js',
dest: ''
});
Writing plugins
Plugins are just functions where the only parameter exposed is the current "context".
Examples
In the following plugin, config
is the target instance:
target.use(function(config) {
config.foo = 'bar';
});
console.log(target.foo);
//=> 'bar'
To have the plugin called in a "child" context, like for iterating over files nodes as they're expanded, just return the plugin function until you get the node you want:
target.use(function fn(config) {
if (!config.node) return fn;
console.log(config);
});
Contexts
To see all available contexts, just do the following:
target.use(function fn(config) {
console.log('-----', config._name, '----');
console.log(config);
console.log('---------------------------');
return fn;
});
Options
Any option from expand-files may be used. Please see that project for the full range of options and documentation.
options properties
The below "special" properties are fine to use either on an options
object or on the root of the object passed to expand-files
.
Either way they will be normalized onto the options
object to ensure that globby and consuming libraries are passed the correct arguments.
special properties
base
cwd
destBase
expand
ext
extDot
extend
flatten
rename
process
srcBase
example
Both of the following will result in expand
being on the options
object.
files({src: '*.js', dest: 'dist/', options: {expand: true}});
files({src: '*.js', dest: 'dist/', expand: true});
