key-value style in-memory database.

• persistant serverside error handling on for edge cases.
• interactive cli mode, which stores variable-like data (for now only supports values of type string and int) to then be retrieved later with methods like "GET", "SET", "DEL", and "EXIT" to exit the program.
• serializes values to bytes before appending to the database struct for optimised performance.
• utilises a tcp server for database logic and validation.

usage:

to start off, you can either set data using SetInt() for key-values with values having type int, or SetString() for key-values with values having type string:

package main

import (
	"fmt"
	"github.com/72sevenzy2/in-memory-database/db"
)

func main() {
	v := db.NewDB()

	err := v.SetInt("test1", 200) // setting ints
	if err != nil {
		panic(err)
	}

	err2 := v.SetString("test2", "hello") // setting strings
	if err2 != nil {
		panic(err2)
	}
}

afterwards, you may retrieve them like so:

package main


import (
	"fmt"
	"github.com/72sevenzy2/in-memory-database/db"
)

func main() {
	v := db.NewDB()

	val, ok := v.GetInt("test1")
	if ok {
		fmt.Println(val)
	}

	val2, ok2 := v.GetString("test2")
	if ok2 {
		fmt.Println(val2)
	}
	
}

if you want to retrieve all key-values with values of type strings/ints:

package main

import (
	"fmt"
	"github.com/72sevenzy2/in-memory-database/db"
)

func main() {
	v := db.NewDB()

	vals, ok := v.GetAllString() // vals is of type map[string]string
	if ok {
		for k, v := range vals {
			fmt.Println(k, v)
		}
	}

	vals2, ok2 := v.GetAllInt() // vals2 is of type map[string]uint32
	if ok2 {
		for k, v := range vals2 {
			fmt.Println(k, v)
		}
	}

}

and finally, to delete keys:

package main

import (
	"fmt"
	"github.com/72sevenzy2/in-memory-database/db"
)

func main() {
	v := db.NewDB()

	v.Del("keyName")

}

interactive cli tutorial:

run the following to begin:

go run .

and follow up by declarin`g a variable:

SET [KeyName] [Value]

(key names only support either integers or strings as of now).

after setting a variable, you can then retrieve it like so:

GET [KeyName]

and it returns the value of the key given.

to delete a variable/key:

DEL [KeyName]

finally, to exit the program, run:

EXIT
