I would like to achieve the following in a project where I'm using browserify:
I would like to generate 2 different bundles from the same sources, each one including a given implementation of a common interface,
requires requires generates
a.js +------------> b.js +------------> c.impl1.js +-----------> bundle.1.js
|
+------------> c.impl2.js +-----------> bundle.2.js
How should I require the different implementations from the b.js file and configure browserify to not to end up with a single bundle with all the dependencies included?
Thanks in advance!
I found out a solution while looking to some unrelated code.
I'm now using this pattern to create an intermediate interface file c.js:
if (process.env.CLASS_IMPL === 'impl1') {
module.exports = require('./c.impl1')
} else {
module.exports = require('./c.impl2')
}
So I export one or other implementation depending on an environment variable I set before running the bundling process.

I am using a pre-built C++ library in my Unreal project using a dynamic library file (let's say it's called MyPluginLib.dll). The library is contained in a plugin, let’s call it MyPlugin.
Building, packaging, playing in editor works fine. However, a packaged build doesn’t start, giving the following error: Code execution cannot proceed, MyPluginLib.dll was not found.
The packaging process places MyPluginLib.dll file in MyGame\Plugins\MyPlugin\Binaries. However, the execution process is seemingly looking for it in MyGame\Binaries – moving the library there manually solves this issue.
Why is the OS unable to find the dll in the first folder? Is there something wrong in the build.cs, or my folder structure?
The folder structure of the plugin folder is as follows:
Includes in Plugins\MyPlugin\Source\ThirdParty\MyPluginLib\
Binaries in Plugins\MyPlugin\Binaries\(PLATFORM)\
The plugin’s Build.cs looks like this:
public class MyPlugin : ModuleRules
{
public MyPlugin(ReadOnlyTargetRules Target) : base(Target)
{
PCHUsage = ModuleRules.PCHUsageMode.UseExplicitOrSharedPCHs;
string PluginRoot = Path.GetFullPath(Path.Combine(ModuleDirectory, "..", ".."));
string PlatformString = Target.Platform.ToString();
string LibraryDirectory = Path.Combine(PluginRoot, "Binaries", PlatformString);
PublicIncludePaths.Add(Path.Combine(PluginRoot, "Source", "ThirdParty", "MyPluginLib"));
if ((Target.Platform == UnrealTargetPlatform.Win64))
{
PublicAdditionalLibraries.Add(Path.Combine(LibraryDirectory, "MyPluginLib.lib"));
RuntimeDependencies.Add(Path.Combine(LibraryDirectory, "MyPluginLib.dll"), StagedFileType.NonUFS);
}
else if (Target.Platform == UnrealTargetPlatform.Linux)
{
// linux binaries...
}
}
Would appreciate any help.
Check your packaged games files, unreal loves to not include certain thing in packaged builds regarding plugins.
Given this code, where should I place the file.json to be able to be found in the runtime?
// path: src/main/kotlin/Server.kt
fun main() {
val serviceAccount = require("file.json")
}
I tried place it under src/main/resources/ without luck. I also use Gradle to compile kotlin to js with kotlin2js plugin.
Assuming the Kotlin compiler puts the created JS file (say server.js) into the default location at build/classes/kotlin/main and the resource file (file.json) into build/resources/main.
And you are running server.js by executing node build/classes/kotlin/main/server.js
According to the NodeJS documentation:
Local modules and JSON files can be imported using a relative path (e.g. ./, ./foo, ./bar/baz, ../foo) that will be resolved against the directory named by __dirname (if defined) or the current working directory.
(https://nodejs.org/api/modules.html#modules_require_id)
In our case __dirname is build/classes/kotlin/main
So the correct require statement is:
val serviceAccount = js("require('../../../resources/main/file.json')")
or if require is defined as a Kotlin function like in the question
val serviceAccount = require("../../../resources/main/file.json")
You may just use js("require('./file.json')") if you do not have import for the require function in Kotlin. The result will be dynamic, so you may cast it to Map.

I try to use Cro to create a Rest API that will publish messages in rabbitMQ. I would like to split my routes in different modules and compose them with an "include". But I would like to be able to share the same connection to rabbitMQ in each of those modules too. I try with "our" but it does not work :
File 1:
unit module XXX::YYY;
use Cro::HTTP::Router;
use Cro::HTTP::Server;
use Cro::HTTP::Log::File;
use XXX::YYY::Route1;
use Net::AMQP;
our $rabbitConnection is export = Net::AMQP.new;
await $rabbitConnection.connect;
my $application = route {
include <api v1 run> => run-routes;
}
...
File 2:
unit module XXX::YYY::Route1;
use UUID;
use Cro::HTTP::Router;
use JSON::Fast;
use Net::AMQP;
my $channel = $XXX::YYY::rabbitConnection.open-channel().result;
$channel.declare-queue("test_task", durable=> True );
sub run-routes() is export { ... }
Error message:
===SORRY!===
No such method 'open-channel' for invocant of type 'Any'
Thanks!
When you define your exportable route function you can specify arguments then in your composing module you can create the shared objects and pass them to the routes. For example in your router module :
sub run-routes ($rmq) is export{
route {
... $rmq is available in here
}
}
Then in your main router you can create your Queue and pass it in when including
my $rmq = # Insert queue creation code here
include product => run-routes( $rmq );
I've not tried this but I can't see any reason why it shouldn't work.
The answer by #Scimon is certainly correct, but it does not addresses the OP. On the other hand, the two comments by #ugexe and #raiph are spot-on, so I'll try to summarize them here and explain what's going on.
The error itself
This is the error:
Error message:
===SORRY!=== No such method 'open-channel' for invocant of type 'Any'
It indicates the invocant ($XXX::YYY::rabbitConnection) is of type Any, which is the type usually assigned to variables when they don't have a defined value; that is, basically, $XXX::YYY::rabbitConnection is not defined. It certainly is not since XXX::YYY is not included among the imported modules, as indicated by #ugexe.
The additioal problem indicated by the OP
That module was eliminated from the imported list because, as indicated by the OP
I certainly code it the wrong way because if i try to add use
XXX::YYY;, i get a Circular module loading detected error
But of course. since use XXX::YYY::Route1; which is file 2, is included in File 1.
The final solution is to reorganize files
That circular dependence probably points out to the fact that they should be in the same file, or else common code should be factored out to a third file, which would be eventually be included by both. So you should have something like
unit module XXX::YYY::Common;
use Net::AMQP;
our $rabbitConnection is export = Net::AMQP.new;
await $rabbitConnection.connect;
And then
use XXX::YYY::Common;
in both modules.
Is it possible to use "dojo/text!" in an Intern functional test?
I am able to setup my test page as a JSON string, but ideally I'd like to externalise the string in a file for ease of editing. I'm just getting started with Intern at the moment so I'm just experimenting with what's possible, but here is the start of my test code).
This works with the commented "testData" variable used, but is currently failing when I try to provide the same String by the dojo/text! statement.
Code:
define([
'intern!object',
'intern/chai!assert',
'dojo/text!./firstTestPageConfig.json',
'require'
], function (registerSuite, assert, PageConfig, require) {
registerSuite({
name: 'firstTest',
'greeting form': function () {
var testData = PageConfig;
// var testData = '{"widgets":[{"name":"alfresco/menus/AlfMenuBar","config":{"widgets":[{"name":"alfresco/menus/AlfMenuBarPopup","config":{"id":"DD1","label":"Drop-Down","iconClass":"alf-configure-icon","widgets":[{"name":"alfresco/menus/AlfMenuGroup","config":{"label":"Group 1","widgets":[{"name":"alfresco/menus/AlfMenuItem","config":{"label":"Item 1","iconClass":"alf-user-icon"}},{"name":"alfresco/menus/AlfMenuItem","config":{"label":"Item 2","iconClass":"alf-password-icon"}}]}},{"name":"alfresco/menus/AlfMenuGroup","config":{"label":"Group 2","widgets":[{"name":"alfresco/menus/AlfMenuItem","config":{"label":"Item 3","iconClass":"alf-help-icon"}}]}}]}}]}}]}';
var testPage = 'http://localhost:8081/share/page/tp/ws/unittest?testdata=';
return this.remote
.get(testPage + testData)
.waitForElementByCssSelector('.alfresco-core-Page.allWidgetsProcessed', 5000)
.elementById('DD1')
.clickElement()
.end()
}
});
});
The error I'm getting is this:
/home/dave/ScratchPad/ShareInternTests/node_modules/intern/node_modules/dojo/dojo.js:742
throw new Error('Failed to load module ' + module.mid + ' from ' + url +
^
Error: Failed to load module dojo/text from /home/dave/ScratchPad/ShareInternTests/dojo/text.js (parent: dojo/text!17!*)

at fs.js:207:20
at Object.oncomplete (fs.js:107:15)
I've tried playing around with the loader/package/map configuration but without any success. It's not clear (to me at least) from the error message whether or not it can't find the file I'm passing to dojo/text (but I've tried full as well as relative paths) or the Dojo module itself ?
I'd just like to confirm that what I'm attempting is possible, before I spend any more time with this... but obviously any solution or example would be greatly appreciated!!
Many thanks,
Dave
To your specific error: You need to install Dojo for your own project if you want to use it. You are trying to load a module that does not exist. You may also try using the copy that comes with Intern, by loading modules from intern/dojo, but this isn’t recommended if you don’t understand the potential caveats of loading this internal library.
To using dojo/text in a functional test, generally: This is not currently possible unless you use the Geezer branch or explicitly use the Dojo 1 loader, because that module relies on functionality that is only exposed by the Dojo 1 loader when running in Node.js. A different text loader module that is fully generic would work, or you could load intern/dojo/node!fs and load the text yourself. This will be addressed in the future.
I just came across the same issue and for me this worked:
define([
"dojo/_base/declare",
"intern/dojo/text!/[PathToText]"
], function (declare, base) {
Seems as if Sitepen has included this in the meantime...
I have a few common files like logger, stopwatch, metrics, etc. Now, I would like to add all of them in 1 common.coffee and place this files in a common folder under lib.
lib/common/logger.coffee
lib/common/metrics.coffee
lib/common/stopwatch.coffee
lib/common.coffee
Now, when I have to use these files. I just do a
require( 'lib/common' )
and should be able to call the logger class
like logger.info, etc in the lib files.
How to go about doing it ? Below is the common.coffee but it requires me to say "Common.logger" whenever I have to use it. I dont want the Common prefix
nconf = require('nconf')
environment = process.env.NODE_ENV || 'development'
nconf.file 'environment', "config/#{environment}.json"
nconf.file 'default', 'config/default.json'
module.exports = {
logger: require('lib/common/logger')
metrics: require('lib/common/metrics') nconf
stopwatch: require('lib/common/stop_watch')
}
Also, how can I make a module of the common folder so that I can just use npm to install it.
You could use destructuring assignments on your require call.
{logger, metrics, stopwatch} = require("lib/common")
another way would be to use a build tool like grunt.js and call a concatination task before building the final deployment articfact.
