What is the best way to add .xlsx and .docx files to the Typescript compilation output?

For my server, I have decided to use Typescript with NodeJS.

One of the challenges I encountered in my server logic is manipulating .xlsx and .docx files. Unfortunately, these file types are not included in the Typescript compilation output. These specific files serve as templates for generating other files.

This is an overview of my project structure:

package.json
package-lock.json
ormconfig.json
tsconfig.json
/src
  /reports
    --other-.ts-files
    Router.ts
    Report.xlsx //Desire this file to be incorporated in the Typescript compilation output
    Report.docx //Desire this file to be incorporated in the Typescript compilation output

I am seeking guidance on how to include .xlsx and .docx files in the Typescript compilation output. Specifically, what modifications should be made in the tsconfig.json file?

Answer №1

1) Deprecated method: It used to be possible to add additional extensions to nodejs, but this approach is no longer recommended.

var fs = require('fs');

require.extensions['.txt'] = function (module, filename) {
    module.exports = fs.readFileSync(filename, 'utf8');
};

var words = require("./words.txt");

2) Utilizing the file API: To read files in Node, you can always leverage the file API.

const fs = require('fs')
const path = require('path')
const css = fs.readFileSync(path.resolve(__dirname, 'email.css'), 'utf8')

3) Loading custom file types with TypeScript and webpack: With TypeScript and webpack, it's feasible to load custom file types such as SVG files. Additional typings are required for Typescript in this scenario, especially for frontend applications.

declare module "*.svg" {
  const content: any;
  export default content;
}

4) XLSX sheet reading library: When it comes to reading XLSX sheets, there is a reliable library named xlsx.
