   |--template.html
|--package.json
|--webpack.config.js

Contents of index.js:
console.log("Hello webpack");

Contents of template.html:

    <!DOCTYPE html>

How to make this folder completely portable, i.e. when running npx webpack or npm run build this always can run well, no matter if working with C:\root_folder\ or with C:\very\longpath\root_folder.
Have successfully ran npx webpack for this example in C:\root_folder\ and then i copied ** root_folder ** like it is into D:\testing\root_folder\ and when running npx webpack from D:\testing\root_folder\ it worked, which obviously shows it is portable.
Summary: It is helpful to store root folders of webpack bundling projects if they belong to other projects in their own project subfolder, so it is useful to be able to have root_folder sometimes in nested folders.
Question: Is there available a way to resolve all root_folder/ scripts with local paths in windows with simple npm scripts or even npx command, so it will not return error for long paths?
Current Answer: Well found which works is copying the nested root_folder to a temporary C:\temp\root_folder and from there do all the npm webpack processing and also module bundling.

Solution

  • So answer which worked here was to mount the project directory and from there run the build.

    All of what is necessary is to have the following npm scripts (in package.json):

    "scripts": {
        "test": "ECHO \"Error: no test specified\" && EXIT 1",
        "build": "(IF EXIST \"%CD%/dist\" RMDIR dist /S /Q) && webpack",
        "nestingcompliance:build": "SUBST Z: \"%CD%\" && PUSHD Z: && npm run build && POPD && SUBST Z: /D"
      }
    

    And then run in cmd line:

    npm run nestingcompliance:build
