How do I get the path to the current script with Node.js?
I found it after looking through the documentation again. What I was looking for were the __filename
and __dirname
module-level variables.
__filename
is the file name of the current module. This is the resolved absolute path of the current module file. (ex:/home/kyle/some/dir/file.js
)__dirname
is the directory name of the current module. (ex:/home/kyle/some/dir
)
This command returns the current directory:
var currentPath = process.cwd();
For example, to use the path to read the file:
var fs = require('fs');
fs.readFile(process.cwd() + "\\text.txt", function(err, data)
{
if(err)
console.log(err)
else
console.log(data.toString());
});
So basically you can do this:
fs.readFile(path.resolve(__dirname, 'settings.json'), 'UTF-8', callback);
Use resolve() instead of concatenating with '/' or '\' else you will run into cross-platform issues.
Note: __dirname is the local path of the module or included script. If you are writing a plugin which needs to know the path of the main script it is:
require.main.filename
or, to just get the folder name:
require('path').dirname(require.main.filename)
Use __dirname!!
__dirname
The directory name of the current module. This the same as the path.dirname() of the __filename
.
Example: running node example.js from /Users/mjr
console.log(__dirname);
// Prints: /Users/mjr
console.log(path.dirname(__filename));
// Prints: /Users/mjr

For ESModules you would want to use:
import.meta.url
