algo.md

Files

• diojarn.go => Main file. It detects databases, checks URL is valid, make connection between other files.
• database.go => Database file. It creates/deletes databases, adds columns to them.
• ping.go => Ping file. It sends ping (ICMP) packet to target URL and returns datas like response time, response code, date, URL status (up or down)
• server.go => Server file. It opens a web server in local network, displays websites and their data in their databases.

Algorithm

• Main file (diojarn.go)

  • Read config file
  • Detect database in "databases/" or specified directory FOR LOOP
    • Compare database names with websites in config file
      • If all database names are equal, return True
      • Else, return False
    • Check return value
      • If False, create database with that name
      • Else, do nothing
  • Send website to Ping file (ping.go)
    • Check URL is valid
      • If True, do nothing
      • Else, return error
    • Send packet
      • Get response code, response time, date and URL status (up or down)
      • Send it to Main file (diojarn.go) with URL
  • Get values from Ping file (ping.go)
    • Send them to Database file (database.go)
      • Open database named URL
        • Add columns using returned values (response code, response time etc.)

• Run server (server.go)

  • Get database from Main file (diojarn.go)
    • Send it to JavaScript chart script
  • Stay alive, loop baby.

What to use?

• front-end
  • Charts (using JavaScript with d3.js)
    • Bar chart (for displaying requests)
    • Horizontal line chart (for displaying errors)
    • Circle chart (for displaying uptime)
  • CSS framework
    • Skeleton
• back-end
  • Chart (terminal)
    • Bar chart (for displaying requests)
  • Web server (local)
    • fasthttp ('cause its fast)
  • Database (local)
    • IDK

Ideas

• Send SMS to user when returned error (like site is down or 404 code received) using Twilio API
• Terminal chart? Maybe?
• Send mails.. Yeah people still using them.

nice work :) ty
