browser-resolve
node.js resolve algorithm with browser field support.
api
resolve(id, opts={}, cb)
Resolve a module path and call cb(err, path [, pkg])
Options:
basedir
- directory to begin resolving frombrowser
- the 'browser' property to use from package.json (defaults to 'browser')filename
- the calling filename where therequire()
call originated (in the source)modules
- object with module id/name -> path mappings to consult before doing manual resolution (use to provide core modules)packageFilter
- transform the parsedpackage.json
contents before looking at themain
fieldpaths
-require.paths
array to use if nothing is found on the normalnode_modules
recursive walk
Options supported by node-resolve can be used.
resolve.sync(id, opts={})
Same as the async resolve, just uses sync methods.
Options supported by node-resolve sync
can be used.
basic usage
you can resolve files like require.resolve()
:
var resolve = require('browser-resolve');
resolve('../', { filename: __filename }, function(err, path) {
console.log(path);
});
$ node example/resolve.js
/home/substack/projects/node-browser-resolve/index.js
core modules
By default, core modules (http, dgram, etc) will return their same name as the path. If you want to have specific paths returned, specify a modules
property in the options object.
var shims = {
http: '/your/path/to/http.js'
};
var resolve = require('browser-resolve');
resolve('fs', { modules: shims }, function(err, path) {
console.log(path);
});
$ node example/builtin.js
/home/substack/projects/node-browser-resolve/builtin/fs.js
browser field
browser-specific versions of modules
{
"name": "custom",
"version": "0.0.0",
"browser": {
"./main.js": "custom.js"
},
"chromeapp": {
"./main.js": "custom-chromeapp.js"
}
}
var resolve = require('browser-resolve');
var parent = { filename: __dirname + '/custom/file.js' /*, browser: 'chromeapp' */ };
resolve('./main.js', parent, function(err, path) {
console.log(path);
});
$ node example/custom.js
/home/substack/projects/node-browser-resolve/example/custom/custom.js
skip
You can skip over dependencies by setting a
browser field
value to false
:
{
"name": "skip",
"version": "0.0.0",
"browser": {
"tar": false
}
}
This is handy if you have code like:
var tar = require('tar');
exports.add = function (a, b) {
return a + b;
};
exports.parse = function () {
return tar.Parse();
};
so that require('tar')
will just return {}
in the browser because you don't
intend to support the .parse()
export in a browser environment.
var resolve = require('browser-resolve');
var parent = { filename: __dirname + '/skip/main.js' };
resolve('tar', parent, function(err, path) {
console.log(path);
});

upgrade notes
Prior to v1.x this library provided shims for node core modules. These have since been removed. If you want to have alternative core modules provided, use the modules
option when calling resolve.
This was done to allow package managers to choose which shims they want to use without browser-resolve being the central point of update.
