How can I set up BaconJS in conjunction with Webpack and CoffeeScript?

Currently in the process of transitioning old code to Webpack and encountering some issues...

Utilizing a dependency loader in TypeScript

import "baconjs/dist/Bacon.js"

And a module in CoffeeScript

@stream = new Bacon.Bus()

Upon running the code, I encountered this error message

zone.js?fad3:269 Uncaught ReferenceError: Bacon is not defined

Attempted to resolve by modifying my webpack configuration....

new webpack.ProvidePlugin({
    ...
    Bacon: "Bacon"
}),

However, it did not yield the desired result.

Module not found: Error: Cannot resolve module 'Bacon' in ...

What steps can be taken to address this issue?

Answer №1

Seems like the issue may lie in importing a module.

Importing a Module for Side Effects Only

While it is not generally recommended, some modules set up global state that can be used by other modules. These modules may not have any exports, or the consumer may not need to use any of their exports. To import these modules, you can do the following:

import "./my-module.js";

Bacon.js is a UMD module and cannot be imported in this manner. You should try:

import {Bacon} from "baconjs/dist/Bacon.js";

Or in CoffeeScript:

Bacon = require('baconjs/dist/Bacon.js')

Also, ensure that the file is in the correct path.

Answer №2

The previous solution was on the right track, but I wanted to avoid having to include 

Bacon = require("baconjs/dist/Bacon.js")
in every coffee script file that needed it. So, I decided to make a change in my Typescript dependencies file...

window['Bacon'] = require('baconjs/dist/Bacon.js');

It appears that this approach is effective and eliminates the need for a require statement in each individual coffeescript file.

I initially attempted:

window.Bacon = require('baconjs/dist/Bacon.js');

However, Typescript did not approve (How do you explicitly set a new property on `window` in TypeScript?)
