Convert a dependency path into a filepath
npm install resolve-dependency-path
const resolvePath = require('resolve-dependency-path');
const resolved = resolvePath({
dependency: './foobar',
filename: 'path/to/file/containing/dependency.js',
directory: 'path/to/all/files'
});
dependency
: the actual dependency path (probably extracted from arequire()
)filename
: the file that required this dependency (likely the file whose dependencies are being extracted)directory
: the root of all modules being processed. Dependencies are often about this root unless they're relative.
If you have a file like:
myapp/foo.js
var require('./bar');
Then if you want to open the file associated with the dependency, you need to resolve ./bar
onto the filesystem.
Since ./bar
is a relative path, it should be resolved relative to foo.js
,
more specifically the directory containing foo.js
, myapp/
. This resolution would yield
myapp/bar.js
.
This is why the filename
attribute is required to use this library.
If you have a non-relative dependency path like:
myapp/foo.js
define([
'bar'
], function(bar) {
});
Then bar
is relative to the root of all files, myapp
. The resolution would yield
myapp/bar.js
.
A more complex example with subdirectories:
myapp/feature1/foo.js
define([
'feature2/bar'
], function(bar) {
});
The dependency feature2/bar
is relative to the root of all files, myapp
, not the file foo.js
.
This is why the directory
attribute is required to use this library.
