When utilizing the file-loader in Webpack with a function in the outputPath parameter, an EISDIR error occurs,

I am attempting to create a specific output format for my locale files in the form of _locales/[locale_shortcut]/[file].json

To achieve this, I am utilizing the file-loader plugin within webpack. While the documentation mentions the use of a function within the outputPath option, there is no clear explanation provided on its structure or expected return value. I assumed it should return a string similar to what you would directly input into outputPath...

The code snippet below is intended for files named like [locale_shortcut].locale.json:

{
    loader: "file-loader",
    options: {
        name: "[name].[ext]",
        outputPath: (t: any) => {
            return "_locales/" + t.replace(".locale.json") + "/";
        },
    },
},

Upon running this code, I encounter an error:

EISDIR: illegal operation on a directory, open '/Users/[user]/projects/[project]/dist/_locales/en/'

List of dependencies used:

  • file-loader 2.0.0
  • webpack 4.27.1
  • typescript 3.1.1

Answer №1

It seems like I need to include the filename in the return path for it to function correctly :/
