What is the reason behind webpack attempting to interpret my readme.md files?

When using Webpack, I encountered the errors below. Despite the build appearing to be successful, I am still puzzled as to why these errors are occurring.

WARNING in ./{snip}/readme.md Module parse failed: C:{snip}\readme.md Unexpected token (1:7) You may need an appropriate loader to handle this file type.

I have been unable to find a solution to ignore certain files, and the fact that it is attempting to render these specific files remains a mystery to me.

Below are snippets from my webpack settings file:

module: {
    loaders: [
        {test: /\.hb.html$/, loader: "handlebars-loader/?helperDirs[]=" + __dirname + "/src/handlebarsHelpers"},
        { test: /\.tsx?$/, loader: "ts-loader?" + JSON.stringify({
            transpileOnly: true
        })}
    ]
},

Entry:

entry: "./src/entry.ts",

Additionally,

resolve: {
    extensions: ["", ".webpack.js", ".web.js", ".ts", ".tsx", ".js"],

I attempted to exclude .md files in the typescript configuration file without success.

The issue wasn't with the configurations, but rather with my code containing query expressions similar to these:

exports.getModule = function (moduleName) {
    var mod = require('./' + moduleName + '');
    return mod;
};

This caused webpack to attempt loading all files, instead of just those in the entry point dependency tree.

The correct diagnosis of the issue is provided in the accepted answer, although the solution could use further clarification. The error occurred during the transition from a non-bundled server to a bundled server.

In my case, the problem manifested as follows:

  // Load the plugin.
  allMods[modName] = require(`../myDir/${modFile}`);

A Possible Fix - Avoid Bundling Files

To address the issue, I needed to prevent webpack from attempting to import the file during build time, as it cannot determine the contents of the variable. However, this approach also means that dynamic imports will not be bundled, which suited my needs since it pertained to a video game modding system.

Here is an illustration:

  // Load the plugin.
  allMods[modName] = eval('require')(`../myDir/${modFile}`);

An Alternative Strategy - Utilize webpack's require.context()

If bundling the files is necessary, one can explore the option of using require.context() (documentation, explanation).

This feature offers flexibility, and here is one implementation method:

const allMods = {};

function importAll(fileContext) {
  fileContext.keys().forEach((key) => {
    // This assumes default exports are used instead of named exports.
    allMods[key] = fileContext(key).default;
  })
}

importAll(require.context('./myDir1', true, /\.js$/));
importAll(require.context('./myDir2', true, /\.js$/));

// Imported files are now stored in allMods.
// File names with extensions serve as keys for reference.

Remember to integrate this function into your application where regular requires are typically coded.
