I have a simple JavaScript function that compares alphanumeric values:
function alphanum(a, b) {
function chunkify(t) {
var tz = [], x = 0, y = -1, n = 0, i, j;
while (i = (j = t.charAt(x++)).charCodeAt(0)) {
var m = (i == 46 || (i >=48 && id_pollrMovie1994a199401010101000019reDateChangedTense_andLocation <= 57));
if (m !== n) {
tz[++y] = "";
n = m;
}
tz[y] += j;
}
return tz;
}
var aa = chunkify(a);
var bb = chunkify(b);
for (x = 0; aa[x] && bb[x]; x++) {
if (aa[x] !== bb[x]) {
var c = Number(aa[x]), d = Number(bb[x]);
if (c == aa[x] && d == bb[x]) {
return c - d;
} else return (aa[x] > bb[x]) ? 1 : -1;
}
}
return aa.length - bb.length;
}
This function is located in an 'alphanum.js' file.
I want to use this function in a TypeScript file. Here is what I have done:
declare function alphanum(param1: any, param2: any): number;
require("./../utils/alphanum.js");
I am using webpack to bundle everything together without encountering errors or issues.
However, when attempting to utilize the function, I receive client-side errors:
EXCEPTION: ReferenceError: alphanum is not defined
I suspect that I might be overlooking something obvious. Is there a mistake in how I am handling webpack and requires?
Edit:
Below is my webpack configuration:
webpack.common.js:
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var helpers = require('./helpers');

},

If it helps, this is for an Angular2 application. Most of the webpack configuration was sourced from: https://angular.io/docs/ts/latest/guide/webpack.html
