how to use the readfile function from fs-extra in javascript

To use the readFile function from the fs-extra module in Node.js, you first need to install it using npm:

index.tsx
npm install fs-extra

After installing the module, you can use the readFile function to read the contents of a file as follows:

index.tsx
const fs = require('fs-extra');

fs.readFile('/path/to/my/file', 'utf-8', (err, data) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(data);
});

In the above code, we first include the fs-extra module and then call its readFile function, passing the path to the file as the first argument and the encoding as the second argument (in this case, 'utf-8').

The readFile function reads the file asynchronously, so we pass a callback function as the third argument that will be called when the file has been read.

If an error occurs during the reading process, the error will be passed to the callback function as the first argument. If there is no error, the contents of the file will be passed as the second argument to the callback function, which we then log to the console.
