Implementing NodeJS without using NPM

What is it?

A boilerplate or a sample built in NodeJS without using any NPM packages covering all (or most) of the Node’s API modules

What is needed?

NodeJS (LTS) ie. >= 8.11.3

How to download & setup?

# Clone this repo using your terminal
git clone https://github.com/faizahmedfarooqui/nodejs.git;

# Go inside the repo
cd nodejs;

# Make a data directory into the root of the project
mkdir .data && cd .data;

# Create 3 more directories into the .data directory
mkdir users checks tokens;

# Go back to project's root 
cd ..;

# Make a logs directory into the root of the project
mkdir .logs;

# Goto the https directory
cd https;

# Now run the command given in the file keyGeneration.txt
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

---------------------------------------------------------------------------------------------------------------------------------------------------------
exit                          Kill the CLI (and the rest of the application)
man                           Show this help page
help                          Alias of the "man" command
stats                         Get statistics on the underlying operating system and resource utilization
List users                    Show a list of all the registered (undeleted) users in the system
More user info --{userId}     Show details of a specified user
List checks --up --down       Show a list of all the active checks in the system, including their state. The "--up" and "--down flags are both optional."
More check info --{checkId}   Show details of a specified check
List logs                     Show a list of all the log files available to be read (compressed only)
More log info --{fileName}    Show details of a specified log file

7. Handling error crash:

• Server request are handled using try-catch block & now rather than app crash send 500 error response (View Code)

8. Debugger Mode:

• For detailed information please use official NodeJS Documentation
• To run this app in debugger mode use command node inspect index-debug.js

9. Performance Hooks:

• Added PerformanceObserver Node Class to observe all the entries & log them out to the CLI (View Code)
• Added Performance Mark & Measure methods to measure all the marked performance steps (View Code)
• To see how it works, run command NODE_DEBUG=performance node index.js in your terminal

10. Cluster:

• Added a new file with clusters, here forks are created by the count of the cpus available (View Code)
• To see how it works, run command node index-cluster.js in your terminal

11. Child Process:

• Using ls commands into the .logs folder from CLI commands list logs (View Code)

12. Other NodeJS Modules:

• Use of Async Hooks module (View Code)
• Use of HTTP/2 module in Client & Server Logic (View Code)
• Use of NET module in Client & Server Logic (View Code)
• Use of REPL module (View Code)
• Use of TLS/SSL module in Client & Server Logic (View Code)
• Use of UDP module in Client & Server Logic (View Code)
