Injecting variables into webpack

Question

I\'m trying to inject a variable into each module within my webpack bundle in order to have debugging information for JS errors per file. I\'ve enabled

node: {
         


        

Answer 1

Write your own loader:

my_project/my_loaders/filename-loader.js:

module.exports = function(source) {
  var injection = 'var __filename = "' + this.resourcePath + '";\n';
  return injection + source;
};

Add it to your pipeline and make sure to add also the configuration:

resolveLoader: {
  modulesDirectories: ["my_loaders", "node_modules"]
}

See the documentation on how to write a loader.
