Does not build under webpack

[pospi]

It should also be mentioned that the above fixes won't actually resolve issues when including the module as-is, only when including the cjsx source. You'll have to configure webpack to define a browser-check environment variable and support coffeescript/react transforms; then you should be able to use something similar to the below to work around the issue:

var ReactCardFormContainer;
if (process.env.IS_BROWSER) {
  ReactCardFormContainer = require('card-react/src/components/card-react-form-container.cjsx');
} else {
  ReactCardFormContainer = require('card-react');
}

What is that for?

} else {
  ReactCardFormContainer = require('card-react');
}

Why not to require cjsx always directly?

It's to do with the way webpack checks files when building. My understanding is basically-

• if you're running in a node environment, you generally want to load precompiled ES5 files to avoid parsing them at runtime. This should be the default behaviour of a module - you don't want to force anyone integrating your library to have to prehandle your module with coffeeify.
• if you're running in webpack, then weback wants to handle your build process for you. This means it wants you to reference source files from your own source files; in fact if you don't it will throw a critical error that you're using preminified files and abort. Hence the two different require paths.

@pospi i'm kinda new to webpack, so i'll ask you this:
If I'll change card-react.js file in the root folder from

module.exports = require('./lib/card-react-form-container');

to

var ReactCardFormContainer;
if (process.env.IS_BROWSER) {
  ReactCardFormContainer = require('src/components/card-react-form-container.cjsx');
} else {
  ReactCardFormContainer = require('lib/card-react-form-container');
}
module.exports = ReactCardFormContainer;

and will change the main file in package.json to card-react.js

will it allow webpack to include the module as-is? and in the same time not interfering with the non-webpack require?

Hey there, after looking into it unfortunately things are a bit more complicated than that. Definitely leave your main export as-is.

I should have mentioned in my earlier post, but IS_BROWSER is a check specific to the app I'm currently working on. Webpack provides a plugin for setting variables in your compilation process, so the way I determine whether I'm running things serverside in node vs. clientside via a compiled webpack build is to use DefinePlugin to set an environment variable I can switch on.

It's a workaround to be sure, but it's enough to get webpack running. The real issue is that @jessepollak has precompiled payment's modules (payment itself and qj) all into the same file, and I believe it's multiple instances of module.exports within one source file that webpack specifically complains about (it's not technically valid node module structure either, but it'll work).

The real fix would be for all modules to compile their files into separate source files and to reference each other separately, so the final build of payment should only include its own source in payment/payment.js and still reference QJ by requireing directly from node_modules. If that change was completed then card-react would be able to load payment by its main entrypoint under both node and webpack without issues.

I'll leave it up to you guys as to whether you think it's worth fixing, with things as they are at the moment it's possible to get both your modules working under either environment so I'm happy either way (:

@pospi I've released version 1.0.18 a few days ago with the merged fix and with the new payment version. I'll be happy to know if it worked for you. Thanks!

Hi @shatran
We are using this module, but we are still having the "Not found module payment/src/payment" which seems pretty reasonable since we are using v3 of npm and the "payment" dependency it's being installed independently from card-react. For now, we bypassed the error editing the "card-react-form-container.js" and "card-react-component.js" files to just require "payment" as an independent module (Payment = require('payment')).
But it would be nice to have a solution for this.

Yes, we are using webpack too 💃

HI @nicoecheza,
Thanks for your comment. are you using version 1.0.18 of card-react? i added payment there as a dependency.

[nicoecheza]

Yes, we are.

[shatran]

I've decided to restore the old require (Payment = require('payment'). I think that's the right way, and like @pospi said "The real fix would be for all modules to compile their files into separate source files and to reference each other separately". so by doing this + hoping the payment requiring qj issue will be solved, it should work fine. @nicoecheza please use version 1.0.19 and let me know if it solved your issue.

@shatran nice, thanks you!
