To get the directory of the currently executing script, you can use the __dirname environment variable in Node.js
For example, let's say we have a file called myscript.js inside a directory called scripts.
Inside this myscript.js file let's log the value of the __dirname environment variable like this,
scripts/myscript.js
console.log("Script executing in directory:", __dirname);
If we were to execute the script using the command node scripts/myscript.js from the terminal, we would get the full absolute path to the directory holding the script file
Script executing in directory: /Users/bob/scripts
like this.
See this example live in repl.it.
