Question

In TypeScript, the 'fs' module can be imported using the syntax `import * as fs from "

import * as fs from "fs";

const image1 = Media.addImage(document, fs.readFileSync("new.png"));

Here is the configuration from my tsconfig.json:

  "compileOnSave": false,
  "compilerOptions": {
    "importHelpers": true,
    "outDir": "./dist/out-tsc",
    "sourceMap": false,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ],
    "module": "commonjs",
  },
    "include": [
        "src/*"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

I am using the fs module to add an image file in my word document with Docx, you can find more information here.

Unfortunately, I encountered an error while trying to import. Can someone provide me with a solution?

Error: ERROR TypeError: fs__WEBPACK_IMPORTED_MODULE_1__.readFileSync is not a function

It has been pointed out in the previous comments that accessing the file system directly from the browser using JavaScript is not possible due to security reasons.

An alternative approach for your task would be to utilize an input of type "file" and then read the content once the corresponding event is triggered.

To achieve this, you can include the following HTML code:

<input type="file" (change)="onFileChanged($event)" accept="image/png, image/jpeg">

On the JavaScript side, you will need to define the onFileChanged method:

onFileChanged(event) {
   const file = event.target.files[0];
   const reader = new FileReader();
   reader.onload = function(e) {
    const result = e.target.result;
    // The actual content of 'result' will vary depending on the method you invoke on the 'reader' object.
    console.log(e.target.result)
  };

  reader.readAsText(file);
  // reader.readAsArrayBuffer(file);
  // reader.readAsBinaryString(file);
}

You should adjust the implementation according to your specific requirements... however, this is the basic process for reading a file's content from the file system.
