How to use the join function from path

Find comprehensive JavaScript path.join code examples handpicked from public code repositorys.

In Node.js, the path.join function is used to join two or more path segments together, using the platform-specific separator as a delimiter.

How does path.join work?

path.join is a method in the Node.js path module that takes one or more path segments as arguments and returns a new string representing the concatenated path segments using the appropriate platform-specific separator (i.e., / for Unix-based systems or \ for Windows-based systems).

If the input path segments contain a leading separator, the resulting concatenated path will begin with that separator. Otherwise, the resulting path will be relative to the current working directory of the Node.js process.

The path.join method also normalizes the resulting path by resolving any . or .. segments in the path, and by converting all path separators to the appropriate platform-specific separator.

By using path.join, developers can safely and easily construct file paths in their Node.js applications, regardless of the underlying platform on which the application is running.

const path = require("path");

// Joining two path segments
const joinedPath = path.join("/Users/john", "Documents", "example.txt");
console.log(joinedPath); // Outputs: /Users/john/Documents/example.txt

// Joining multiple path segments
const joinedPaths = path.join(
  "/Users/john",
  "Documents",
  "folder",
  "subfolder",
  "example.txt"
);
console.log(joinedPaths); // Outputs: /Users/john/Documents/folder/subfolder/example.txt

In this example, we're using path.join to construct two file paths. The first example joins two path segments (/Users/john and Documents) into a single path, and then appends the filename example.txt. The resulting file path is /Users/john/Documents/example.txt. The second example joins multiple path segments (/Users/john, Documents, folder, subfolder, and example.txt) into a single path. The resulting file path is /Users/john/Documents/folder/subfolder/example.txt. Notice how path.join automatically inserts the appropriate platform-specific separator between each path segment, and normalizes the resulting path to use that separator consistently. This ensures that the resulting path is valid and can be used reliably on any platform.
