How does webpack loader context work?

Question

webpack

Hello, I wrote such a loader

const loaderUtils = require("loader-utils");

module.exports = function loader(content, options, map, meta) {
  if (!options) options = loaderUtils.getOptions(this);
  if (options.output) {
    const name = loaderUtils.interpolateName(this, options.output, options);
    this.emitFile(name, content);
  }
  content = "123loadertext";
  this.callback(null, content, map, meta);
};

the bottom line is that it should be able to be called as

require(`lite-file-loader?{"output":"sameName.txt"}!..someContentOfLoaderChain`)

so

const emitFile = require("lite-file-loader");
          emitFile(code, { output: "somename.txt" });

In the first case everything works but in the second

Template execution failed: TypeError: this.emitFile is not a function

Why is the context of the loader normal the first time, but not the second time))
