What causes the EISDIR, read error?

The EISDIR, read error typically occurs when the Node.js program tries to read a directory as if it were a file. This can happen if you're using the "fs" module to read files and accidentally pass a directory path instead of a file path.

How to fix the EISDIR, read error

Here are some tips and solutions to fix the EISDIR, read error:

1. Check the file path

Make sure that you're passing the correct file path to the "fs" module. If you're trying to read a directory, use the "fs.readdir" method instead of "fs.readFile".

<pre>
const fs = require('fs');

fs.readdir('/path/to/directory', (err, files) => {
  if (err) throw err;
  console.log(files);
});
</pre>

2. Use try-catch blocks

Wrap your file reading code in a try-catch block to handle any errors that may occur.

<pre>
const fs = require('fs');

try {
  const data = fs.readFileSync('/path/to/file');
  console.log(data);
} catch (err) {
  console.error(err);
}
</pre>

3. Ensure file permissions are set correctly

Check that you have the necessary permissions to read the file or directory. You may need to change the file permissions using the "chmod" command.

Conclusion

The EISDIR, read error is a common issue in Node.js that can be easily fixed by checking the file path, using try-catch blocks, and ensuring correct file permissions. With these tips and solutions, you should be able to overcome this error and continue with your programming tasks.
