how to use the accesssync function from the fs-extra library in typescript

To use the accesssync function from the fs-extra library in TypeScript, you need to import the library and use it as follows:

index.ts
import { accessSync } from 'fs-extra';
import { constants } from 'fs';

try {
  accessSync('/path/to/file', constants.F_OK); // the second argument is the mode
  console.log('File exists.');
} catch (error) {
  console.error('File does not exist.');
}

In the example above, we imported the accessSync function from the fs-extra library and the constants object from the fs library. We then used the accessSync function to check if a file exists at a given path. The second argument of the accessSync function is the mode, which in this case is constants.F_OK indicating that the function should check only for file existence.

If the file exists, the message "File exists." will be logged to the console. If the file does not exist, the message "File does not exist." will be logged to the console.
