delete a json file in typescript

To delete a JSON file in TypeScript, we need to use the File System module of Node.js. Here's how we can delete a JSON file in TypeScript:

index.ts
import * as fs from 'fs';

const filePath: string = 'path/to/your/file.json';

fs.unlink(filePath, (err: NodeJS.ErrnoException | null) => {
  if (err) {
    console.error(err);
    return;
  }
  
  console.log(`File ${filePath} has been deleted.`);
});

We first import the fs module using import * as fs from 'fs';. fs stands for File System and provides a way to interact with the file system in Node.js.

Then, we define the path to our JSON file in the filePath variable.

Next, we use the fs.unlink() method to delete the file. unlink() takes two arguments: the file path and a callback function that will be called after the file is deleted. If there's an error, the callback function will receive an error object as its first argument. Otherwise, the first argument will be null.

In our callback function, we just log a message to the console if the file was deleted successfully. If there's an error, we log the error message to the console.

That's it! With this code snippet, you can delete a JSON file in TypeScript using the File System module of Node.js.
