This learning path dives into putting the fundamentals of Node into use by creating a Todo CLI application. You will learn about the process module and how to access the argv array to capture arguments from the command line. You will work with a JSON file as a database by using the filesystem and path module to read and write todos.


Learning Objectives


  • Understand the structure of the argv array
  • Learn how to capture commands from the argv array
  • Implement functions to capture the arguments and execute code
  • How to require the read and write methods from the Node filesystem promise module
  • Explain the path module’s __dirname argument
  • Understand how to use a JSON file as a database
  • Understand the purpose of using the filesystem promise module
  • Implement functions to read and write to the JSON file
  • Implement handler functions to invoke the read/write functions.
  • Understand the coding practice to create a separation of concerns between handler functions and module methods
  • Explain how to export functions through the use of the Node CommonJS system
  • Understand how to use exported functions in another file
  • Implement handler functions to complete and remove todos
  • Implement the Filter method to exclude specific data from an array
  • Implement the Map method to modify a specific element from an array
  • Implement with the spread operator to modify object data
  • Use the NOT operator to reverse the current value of the todo object’s complete property 
  • Understand how to use exported functions in another file
