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
