Converting the 'require' call to an import may be a more efficient method when importing package.json in a typescript file

Question

Converting the 'require' call to an import may be a more efficient method when importing package.json in a typescript file

In my current project, I am creating a class where I am directly accessing the package version number like this:

const pkg = require('../package.json')

export class MyClass() {
    constructor() {
        // Set the base version from package.json:
        this.version = pkg.version
    }
}

However, the Typescript compiler is giving me a friendly warning about using 'require' and suggesting to convert it to an import statement.

I wonder if it's possible to do so with a .json file?

What is considered the best practice for importing a package.json in a .ts file?

To easily access the JSON data in your TypeScript project, you can activate the resolveJsonModule option by updating the compilerOptions within the tsconfig.json file.

tsconfig.json

{
  "compilerOptions": {
     "resolveJsonModule" : true,
  }
}

myclass.ts

import {releaseDate} from ('../package.json');

export class MyNewClass() {
  releaseDate: string;

  constructor() {
    this.releaseDate = releaseDate;
  }
}

To bring in external modules, you can utilize the import keyword.

import myPackage from './package.json';

export default class NewClass {
    public version: string;
    constructor(pkg: any) {
        this.version = pkg.version;
    }
}

It's important to remember that by importing a module, your class becomes reliant on that specific file. It is recommended to pass the package as an argument in the constructor function instead.
