100 Days of Node

A Node.js curriculum for 100 days of code. A 100 Days of Code challenge, strictly focusing on Node and Node-adjacent code.

I created this repository to learn the breadth and depth of Node. It became a source to help other developers learn more about using Node. Spend 100 days learning all about the in and outs of Node; what it can do; and where it's the best (and worst) technology to solve any particular challenge.

Any suggestions for little programs, code challenges, or applications that can showcase different features and abilities of Node that could be added to this list would be greatly appreciated...

101. Profit!

000 "Hello World"

• Install Node.js
• Write "Hello World"

Let's start with an easy win!

1. Install Node.js
2. Create a directory named 000
3. Create a script named hello-world.js
4. Import http with require
5. Serve a text respons of Hello World to port 8124
6. Console.log an message saying what port is running

001 Read env variables

1. Create a directory named 001
2. Create a script named env.js
3. Console.log the values of process.version and process.env

002 Write a script that adds two numbers

1. Create a directory named 002
2. Create a script named add.js
3. Write a function that adds two numbers
4. Console.log the results of adding two numbers

003 Use the Node REPL

REPL stands for Read Evaluate Print Loop. The REPL session provides a way to quickly test simple JavaScript code.

1. Create a directory named 003
2. Create a script named repl.js
3. Write a script that enters a REPL session
4. Have the script console.log a message on exiting the REPL session
5. Run your REPL script
6. Console.log the global variable
7. Add a variable to the global variable
8. Console.log your new variable

004 Accept arguments from the command line

Adding arguments into your node command (node arguments.js env=dev) will add them as strings to the process.argv array.

1. Create a directory named 004
2. Create a script named arguments.js
3. Write a script to console.log all of the arguments passed in, but only the arguments that you pass in
4. Run a command that passes in multiples arguments such as: node 004/arguments.js name=nathan surname=lilly devMode=test singularArg

005 Explore console commands

There is a built in console command in Node, much like you'd find in the browser.

1. Create a directory named 005
2. Create a script named console.js
3. Write a script using the log method with variables passed in console.log('My %s has %d ears', 'cat', 2)
4. Use the count method several times
5. Use the clear method
6. Use the count method at least one more time
7. Reset the count
8. Print the stack trace
9. Print an error message with an error code
10. Print a table
11. Measure the time from the first console event to the end of the console events

006 Accept input on the command line

1. Create a directory named 006
2. Create a script named input.js
3. Ask three questions and print their input
4. Use a conditional to check the answer for at least one of the questions

007 Use node import/export modules

1. Create a directory named 007
2. Create a script named import.js
3. Create a script named export.js
4. Write an object into export.js
5. Import the contents of export.js into 'import.js and log it to the console
6. Add a function to the object
7. Import and use the function
