API - Clarify Upgrade Path for Deprecated Functionality

[smably]

Reading through the loader documentation, I noticed that this.exec is deprecated, but the docs don't mention why it was deprecated or whether there is a different API that should be used in its place. This would be helpful information for loader authors, especially since webpack-maintained loaders that rely on this functionality (e.g.) still appear to use this API.

Sounds reasonable, thanks for pointing this out @smably. Once we figure out the answer to this would you be interested in submitting a pr to resolve this?

@webpack/documentation-team can someone point us to the replacement method or new workflow that replaced this.exec?

[smably]

Yes, I'd be happy to open a PR to fix this!

You can replace it with the following function:

const Module = require("module");
function exec(code, filename) {
  const module = new Module(filename, this);
  module.paths = Module._nodeModulePaths(this.context);
  module.filename = filename;
  module._compile(code, filename);
  return module.exports;
}

@smably I know it's been a little while but does the above comment answer your question? Would you still be interested in submitting a PR?

Usage:

const tmpModule = exec.call(this, content, this.resource)
...
// Don't forget
delete require.cache[this.resource]
