path.resolve for absolute paths in Node.js - Mini Project: Build & Apply

Using path.resolve to Create Absolute Paths in Node.js

📖 Scenario: You are building a Node.js script that needs to work with file paths. To avoid errors caused by relative paths, you want to convert file paths to absolute paths using path.resolve.

🎯 Goal: Build a simple Node.js script that uses path.resolve to convert a relative file path to an absolute path.

📋 What You'll Learn

Create a variable with a relative file path string

Import the path module

Use path.resolve to convert the relative path to an absolute path

Store the absolute path in a variable

💡 Why This Matters

🌍 Real World

In real projects, converting relative paths to absolute paths helps avoid errors when reading or writing files, especially when scripts run from different folders.

💼 Career

Understanding path.resolve is important for backend developers working with file systems, build tools, or server scripts in Node.js.

1

Create a relative file path variable

Create a variable called relativePath and set it to the string './files/data.txt'.

Node.js

# Create a variable called relativePath with the value './files/data.txt'
# Your code here

Need a hint?

Use const relativePath = './files/data.txt'; to create the variable.

2

Import the path module

Import the built-in Node.js module path using const path = require('path');.

Node.js

const relativePath = './files/data.txt';
// Import the path module
# Your code here

Need a hint?

Use const path = require('path'); to import the module.

3

Use path.resolve to get absolute path

Create a variable called absolutePath and set it to the result of path.resolve(relativePath).

Node.js

const relativePath = './files/data.txt';
const path = require('path');
// Use path.resolve to convert relativePath to absolutePath
# Your code here

Need a hint?

Use const absolutePath = path.resolve(relativePath); to get the absolute path.

4

Complete the script with module export

Add module.exports = { relativePath, absolutePath }; at the end to export both variables.

Node.js

const relativePath = './files/data.txt';
const path = require('path');
const absolutePath = path.resolve(relativePath);
// Export the variables
# Your code here

Need a hint?

Use module.exports = { relativePath, absolutePath }; to export the variables.
