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.

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
