Doesn't work with webpack 5

[ajotka]

Hi,

I am working on upgrade your different package - svg sprite loader.
And I found out that webpack-toolkit is also not compatible with Webpack 5.

I have solution (I hope), but I don't know how do you want to keep/provide backward compatibility.

Solution:

lib/createCachedInputFileSystem.js

var fs = require('fs');
var CachedInputFileSystem = require('enhanced-resolve/lib/CachedInputFileSystem');

module.exports = function createCachedInputFileSystem() {
  return new CachedInputFileSystem(fs, 60000);
};

lib/addEntry.js

var EntryPlugin = require('webpack/lib/EntryPlugin');

/**
 * Add single entry programmatically. Loaders syntax allowed in entryPath param.
 * @param {Compiler} compiler
 * @param {String} entry Entry location. Relative to compiler context path. Can contains loaders requests
 * @param {String} [name='main'] Entry name
 * @param {String} [context]
 */
module.exports = function addEntry(compiler, entry, name, context) {
  var ctx = context || compiler.options.context;
  var n = name || 'main';

  var dep = new EntryPlugin(ctx, entry, n);

  compiler.apply(dep);
};
