Webpacking npm module and using its files

[psimyn]

you should be able to just require('alloy-editor') where you need it in particular components - if the path doesn't resolve you can potentially add a alias to the resolve section of webpack config.

For the css, right way is still being decided.. If you are using current master, you should be able to include in main.scss, but you'll need to resolve the path relative to node_modules. For example

@include "alloyeditor/dist/alloy-editor/assets/alloy-editor-ocean-min.css";

otherwise you can add part/all of that path to the includePaths in webpack config, e.g.:

 { test: /\.scss$/,
    loader: ExtractTextPlugin.extract('css?module&localIdentName=[local]__[hash:base64:5]' +
      '&sourceMap!sass?sourceMap&outputStyle=expanded' +
      '&includePaths[]=' + (path.resolve(__dirname, './node_modules')) +
      '&includePaths[]=' + (path.resolve(__dirname, './node_modules/alloyeditor/dist/alloy-editor/assets')))
  }

will allow you to just @include "alloy-editor-ocean-min.css"

This will slightly change after #35, but it's probably worth thinking about how we want to handle external style deps.

@choonkending thoughts?

@psimyn Good analysis.

I think having your first @include "alloyeditor/dist/alloy-editor/assets/alloy-editor-ocean-min.css"; is neater, especially if you are debugging and looking through the scss/css, it won't be immediately apparent that it belongs from a node module if we do it @include "alloy-editor-ocean-min.css".

I'm not using the current master probably the version before react-hot-loader was added. Well in this case if I wanted to use AlloyEditor,it would be import * from 'alloy-editor' (ES6) in the component I'm using it at right? Also can you explain the alias for the for the resolve part of the webpack.config file a bit more. Thanks btw I really appreciate it.

[choonkending]

@kkotwal94 Yes you can import it that way.

As for the resolve part of the webpack config, you can read more here.

 resolve: {
      extensions: ['', '.react.js', '.js', '.jsx', '.scss'],
      modulesDirectories: [
        "app", "node_modules"
      ]
    },

This tells webpack to search through those directories (besides the current directory) when it encounters a file/module with those extensions.

The resident webpack expert here is @psimyn, was that correct? Gimme a 👍

[kkotwal94]

resolve: {
      extensions: ['', '.react.js', '.js', '.jsx', '.scss', '.css'],
      modulesDirectories: [
        "app", "node_modules"
      ],
      alias: {
      alloyeditor : '../../node_modules/alloyeditor/dist/alloy-editor/alloy-editor-all.js'
      }
    },

After looking at the documentation and trying this, hitting npm runscript start or watch, both tell me that it still can't resolve the module.

[choonkending]

If your alias is alloyeditor, did you import alloyeditor or alloy-editor.

Otherwise check the path for alloyeditor, whether it really is the correct
directory. It'll be helpful if you paste your webpack config + what error
is thrown here if the above suggestions don't work out :)

As for importing it, i tried 3 ways.

import * from alloyeditor;
import * as alloy from alloyeditor;
require("alloyeditor");

My file structure is here : https://github.com/kkotwal94/IsoReportProcessor

as for the error it is

ERROR in ./components/NewReport.js
Module not found: Error: Cannot resolve module 'alloy-editor' in /home/karan/Documents/IsoReportProcessor/app/components
 @ ./components/NewReport.js 33:19-42

when importing * as alloy from alloyeditor

and

Cannot find module 'alloyeditor'

when hitting npm start (running server.js) however webpack does not spit and issues if I change it during it is watching.

I also tried finding the path from the directory, and it still gives me the same issue.

[choonkending]

@kkotwal94 No luck on my end.

Not sure about how alloyeditor is meant to be used. I tried npm installing the package, and I added a "main": "dist/alloy-editor/alloy-editor-all-min.js", into the package.json for alloyeditor.

Then I could import * from alloyeditor, but I set it up as an entry point only for the browser so the server won't throw an error. (There were certain window checks in alloyeditor).

// Browser 
    entry: {
      app: "./app",
      test: "./components/Test"
    },

I required that <script type="text/javascript" charset="utf-8" src="/assets/test.js"></script> in my base.html just to test it out. Not sure how it s meant to be used. Perhaps you could create an issue in alloyeditor and get some clarification.

[kkotwal94]

gotchya, well I guess i'll be back with a solution. Perhaps maybe you know any wysiwyg that works with requirejs/commonjs/amd loaders? Alloy-editor was the nicest/cleanest one I knew and it looks like they are working on it. They didn't write alloy-editor to be used in global environments like this from what I figured out.

EDIT: liferay/alloy-editor#304
looks like someone already opened a issue for it a couple hours ago!

@kkotwal94 Good work!!

[choonkending]

@kkotwal94 Will close unless you have more questions :)
