require-without-cache

require without cache

How to use

npm install require-without-cache
var requireWithoutCache = require('require-without-cache')
  , hoge = requireWithoutCache('./path/to/module', require)
  ;
 
// ...

Using case

It is intended to be used in the spec file.

target file

var model = require('path/to/model').create();
 
exports.handle = function (cb) {
  model.get('foo/model', function (err, res) {
    cb(err, res);
  });
};

spec file

var requireWithoutCache = require('require-without-cache')
  , sinon = require('sinon')
  , assert = require('assert')
  ;
 
describe('#handle', function () {
  it('should be error', function (done) {
    var model = require('path/to/model')
      , sinon = require('sinon')
      , target
      ;
 
    sinon.stub(model, 'create', function () {
      return {get: function (name, cb) { return cb('an_error'); }};
    });
 
    target = requireWithoutCache('./path/to/module', require); // [1]
    target.handle(function (err, data) {
      assert.ok(err);
      model.create.restore();
      done();
    });
  });
});

if [1] use normal require, target may be cache.

In that case, model does not replace the stub.

by require.cache

However, you may want to carry out the test without a problem if you use the require-without-cache.

API

  • requireWithoutCache(path, require)
    • path {String} filePath
    • require {Function} require method

If using custom require

Please define an API for use by the following.

var path = require('path');
 
function requireFromAppRoot(relativePath) {
  var absolutePath
    ;
 
  // sample require system
  absolutePath = requireFromAppRoot.resolve(relativePath);
  return require(absolutePath);
};
 
requireFromAppRoot.resolve = function (relativePath) {
  var absolutePath = path.resolve(app_route, relativePath);
  return require.resolve(absolutePath);
}
 
Object.defineProperty(requireFromAppRoot, 'cache', {
  get: function () {
    return require.cache;
  }
});

require-without-cache need require.resolve and require.cache
