如何使用webpack从node_modules加载脚本

Question

I need to use the script-loader to load a script from node_modules. I've tried doing the following require in my client_entry.js

require('script-loader!canvas-to-blob');

but I get the following error in my browser:

VM1702:1Uncaught ReferenceError: module is not defined
    at eval (eval at module.exports (http://patientwisdom-dev.com:8080/index.js:164122:9), <anonymous>:1:1)
    at eval (<anonymous>)

I also tried:

require('script-loader!canvas-to-blob/index.js');

still no luck

fyi, this works for js files with a relative path:

require('script-loader!./test.js'); // works

but not for stuff from node_modules

Answer 1

You just need the complete relative path including node_modules .

Depending on where in your project your js file is relative to node_modules it might look something like this.

require('script-loader!../../node_modules/canvas-to-blob/index.js');
