EZ DB

This package provides simple interfaces for working with basic key-value storage in your Go application.

EZ DB is not a database unto itself. If you want more control or features, just use the appropriate database software and connector for your needs.

System requirements

• Go v1.21

Basic usage

The primary interface in EZ DB is Collection[T] which reflects a single key-value store. This is analogous to tables in RDBMS, collections in NoSQL databases etc.

Collections use a generic type T to specify the document type. You can use this to enforce a document schema. This example creates a collection which only accepts Student documents:

package main

import "github.com/annybs/ezdb"

type Student struct {
	Name string
	Age int
}

var db = ezdb.Memory[Student](nil)

func main() {
	db.Open()
	db.Put("annie", Student{Name: "Annie", Age: "32"})
	db.Close()
}

In other cases, such as media stores, you may prefer not to specify a document type. This example allows arbitrary bytes to be written:

package main

import "github.com/annybs/ezdb"

var db = ezdb.Memory[[]byte](nil)

func main() {
	db.Open()
	db.Put("data", []byte("arbitrary bytes"))
	db.Close()
}

Marshaling data

Some database backends require marshaling and unmarshaling data. The DocumentMarshaler[T1, T2] interface allows you to use whatever marshaler suits your needs or the requirements of your chosen database.

The following marshalers are included in EZ DB:

• Bytes allows you to write []byte directly to a database that requires []byte
• JSON[T] marshals your data T to []byte using encoding/json

Supported databases

The following databases are included in EZ DB:

• LevelDB[T] is fast key-value storage on disk
• Memory[T] is essentially a wrapper for map[string]T. It can be provided another Collection to use as a persistence backend
