Are you looking to resolve TypeScript warnings related to imports managed by Webpack loaders?

Setting up a new project with Svelte, Webpack, and TypeScript based on this template. Ran the scripts/setupTypeScript.js script to switch to TypeScript after initial setup.

Encountering errors in VSCode and TypeScript when importing non-TypeScript files:

import myContent from './some-file.txt';
// -> Cannot find module './some-file.txt' or its corresponding type declarations.ts(2307)

The imports work technically, but constant errors are disrupting live-reload. Is there a way for TypeScript to ignore these imports and trust Webpack to handle them? Some of the files are binary, so copying into .ts files isn't an option.

Below are the provided Webpack and TS configurations:

webpack.config.js:

const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const path = require('path');
const sveltePreprocess = require('svelte-preprocess');

const mode = process.env.NODE_ENV || 'development';
const prod = mode === 'production';

module.exports = {
    // webpack configuration here
};

tsconfig.json:

{
        "extends": "@tsconfig/svelte/tsconfig.json",
        "include": ["src/**/*.ts", "src/node_modules/**/*.ts"],
        "exclude": ["node_modules/*", "__sapper__/*", "static/*"]
}

Create a new file named global.d.ts and include the following code to ensure it is recognized by your project:

declare module "*.txt";

This declaration informs TypeScript that any import ending with .txt should be treated as type any. Alternatively, you can export a default value with a different type like this:

declare module "*.txt" {
    const content: string;
    export default content;
}
