Source mapping points to incorrect path (still/again)

I worked out a temporary work-around for users of rlayers!
I'm sharing this here as-is, without any guarantees or warranties about its correctness. USE AT YOUR OWN RISK.

Put the script below into the root of your project as an .mjs file (e.g. fix-rlayers.mjs), and install the npm packages fs-extra and globby if you don't already have them.
Then run node fix-rlayers.mjs from the root of your project.

You can optionally add a script entry to your package.json if you want, maybe even the postinstall script, which is run automatically after you run npm install; this should help the fix be applied even in a CI environment.

fix-rlayers.mjs:

import fs from "fs-extra";
import { globbySync as globby } from "globby";

process.chdir("node_modules/rlayers");

fs.copySync("src", ".", { recursive: true });
const allMaps = globby("**/*.map");
for (const mapPath of allMaps) {
  const m = fs.readJSONSync(mapPath);
  m["sourceRoot"] = "";
  m["sources"] = m["sources"].map((s) => {
    const parts = s.split("/");
    return parts[parts.length - 1];
  });
  fs.writeJSONSync(mapPath, m);
}

Update: from trying around a bit myself, the quickest fix is changing tsc's sourceRoot and outDir to its default (which is right next to each .ts file), and then just packaging the whole workspace.

tsconfig.json change:

diff --git a/tsconfig.json b/tsconfig.json
index 0250660..c782d8c 100644
--- a/tsconfig.json
+++ b/tsconfig.json

This is annoying during development because it clutters your workspace, so some workarounds are probably desirable.

Still getting error after changing tsconfig.json to "inlineSources": true,

You seem to have some 3rd party source map loader installed - it is this loader that generates the message.

I will probably end up completely removing the source maps, as there seem to be various extensions that can read them and given that they are used only for debugging, they are probably of no interest to most of the users.

Fixed it using @lehnerpat fix .mjs file.

Keep up the good work!

Can you please test if your tools work with this source map in control/RFullScreen.js.map

Should be fixed in 1.3.2
