json + boltDB = joltDB

An api written in Go to simplify working with boltdb/bolt. JoltDB saves structs as json and retrieves the stored data as json.

Please have a look at the example.

Usage

package main
import (
    "fmt"
    "github.com/jasonmain/joltDB"
)
type User struct {
    ID   string `json:"id"`
    Name string `json:"name"`
    Age  string `json:"age"`
}
func main() {
    // Open boltDB database in working dir.
    // If one isn't there it will be created.
    joltDB.Open("./data.db")
    // Add some users.
    users := []*User{
        {"100", "Ken", "39"},
        {"101", "Max", "25"},
        {"102", "Bill", "23"},
        {"103", "Martin", "54"},
        {"104", "Kross", "33"},
    }
    // Save users.
    for _, user := range users {
        // With simple key
        if err := joltDB.Save("users", user.ID, user); err != nil {
            fmt.Println(err)
        }
        // With a prefixed key.
        if err := joltDB.Save("users", user.Name+":"+user.ID, user); err != nil {
            fmt.Println(err)
        }
    }
    // Get one user.
    getUser, err := joltDB.GetOne("users", "103")
    if err != nil {
        fmt.Println(err)
    }
    // Get full user list.
    userList, err := joltDB.List("users")
    if err != nil {
        fmt.Println(err)
    }
    // Get user list by range.
    userListRange, err := joltDB.ListRange("users", "101", "103")
    if err != nil {
        fmt.Println(err)
    }
    // Get user list by Prefix.
    userListPrefix, err := joltDB.ListPrefix("users", "K")
    if err != nil {
        fmt.Println(err)
    }
    // Print the saved user lists.
    fmt.Printf("\n\rGet One User:\n\r%s\n\r\n\r", getUser)
    fmt.Printf("Full User List:\n\r%s\n\r\n\r", userList)
    fmt.Printf("User List By Range:\n\r%s\n\r\n\r", userListRange)
    fmt.Printf("User List By Prefix:\n\r%s", userListPrefix)
