Webpack dynamic require throwing error

I have the following piece of code that works well:

require.ensure(['./core/sample-form.js'], require => {
    require('./core/sample-form.js');  
});

Now if I put that string into a variable:

const ajaxJs = './core/sample-form.js';
require.ensure([ajaxJs], require => {
    require(ajaxJs);  // eslint-disable-line import/no-dynamic-require
});

It throws the following error:

Uncaught (in promise) Error: Cannot find module "." at webpackMissingModule

Is there any way I can use a variable for that require?

Take a look at Webpack's Context Module.

Apparently, when you attempt to dynamicly require a module, Webpack will try to parse the input expression to a context.

Try the following code (haven't tested this):

const ajaxJs = './sample-form.js';
core = require.context('./core', true, /^\.\/.*\.js$/);
require.ensure([], () => {
    core(ajaxJs);
});

Webpack can't figure out which modules to bundle when the name is dynamic variable. You can't use variable name in require. You'll have to do something like :

require.ensure(['./core/sample-form.js'], require => {
    require('./core/sample-form.js');  // eslint-disable-line import/no-dynamic-require
});

This answer can help.
