Node.js File System Exercise

Getting Started

  1. Open your command line and navigate to your repos directory (if you do not have a repos folder, then you can use mkdir repos to create one)
  2. Use this template repository to start a new project in your repos folder: git clone <repo_name>
  3. cd repo_name to navigate into your new repo directory
  4. Start Visual Studio Code and select 'Open Folder'. Then select repo_name to open the folder in the editor (or just type code . in your terminal inside the repo directory)
  5. Follow the instructions on the README.md file to complete exercises

Exercise

Steps

  • Create a new project folder called node_fs
  • Inside of node_fs, create the 4 following js files:
    • createFile.js
    • readFile.js
    • updateFile.js
    • deleteFile.js
  • Inside of createFile.js:
  • Require the fs module
  • Implement the fs.writeFile() function, creating a txt file called HelloWorld.txt, with Hello, World! inside
  • Use the async version
  • Run node createFile.js to create the file
  • Inside of readFile.js:
    • Require the fs module
    • Implement the fs.readFile()
    • You can either read the contents of the HelloWorld.txt file, or any other file you create in your project
    • Run node readFile.js to read the file to the console
  • Inside of updateFile.js
    • Require the fs module
    • Using the appendFile() function, append some text to the end of your HelloWorld.txt
    • Run node update.js
  • Inside of deleteFile.js
    • Require the fs module
    • Implement the fs.unlink()
    • Run node deleteFile.js

BONUS

Part 1:

  • Using both the http and fs module, create a server that sends an html page back to the client upon request. You must have at minimum two html pages with corresponding routes, and a 404 not found page.

Part 2:

  • Create a custom logger for accounting for requests to your server. Each time a request event is emitted by your server, send the appropriate html file back, but also log the following information to a file: Request method, url, response status code, and timestamp
  • The timestamp can be any format you like, but it a least should show the time of day that the request was made
