I'm using Webpack to bundle dependencies, one of which is the emailing service postmark. This service depends upon something called child_process that apparently ships with node.
The problem is, when I attempt to run webpack to bundle my app, it complains:
Module not found: Error: Cannot resolve module 'child_process' in ...
Most of the answers online say that, in response to this error, I should add the line:
node: {
child_process: 'empty'
}
to my webpack config. But this makes no sense, because then webpack just doesn't try to look for child_process, and consequently, when I run my app, I get the following error:
Uncaught TypeError: exec is not a function
which is an error from postmark (the service that relies upon child_process) complaining that the exec function within the child_process module doesn't exist.
Thus, I'm wondering how I can include the child_process module in my build without webpack complaining?
Front-end developer of Postmark here.
It looks like you're trying to bundle postmark.js into your client-side JavaScript but https://github.com/wildbit/postmark.js is a Node.js library. This means it will not run in the browser and requires a running Node.js server.
The main reason for not supporting browser environment is security. As you can see in this example:
var postmark = require("postmark");
var client = new postmark.Client("<server key>");
it requires you to insert the auth token. Bundling this with your client-side JS would expose it and allow everyone access your postmark account API.
Hope this clarifies it.
