xyproto/simplehstore: :convenience_store: Easy way to use a PostgreSQL database (and the HSTORE feature) from Go

Easy way to use a PostgreSQL database (and the HSTORE feature) from Go.

godoc.org

• Requires PostgreSQL 9.1 or later.
• Requires Go 1.10 or later.
• Supports simple use of lists, hashmaps, sets and key/values.
• Deals mainly with strings.
• Uses the pq package.
• Modeled after simpleredis.
• Uses SQL queries with HSTORE for the KeyValue and HashMap types.
• Uses regular SQL for the List and Set types.

package main

import (
    "log"

    db "github.com/xyproto/simplehstore"
)

func main() {
    // Check if the local db service is up
    if err := db.TestConnection(); err != nil {
        log.Fatalln("Could not connect to local database. Is the service up and running?")
    }

    // Create a Host, connect to the local db server
    host := db.New()

    // Connecting to a different host/port
    //host := db.NewHost("server:5432/db")

    // Connect to a different db host/port, with a username and password
    // host := db.NewHost("username:password@server/db")

    // Close the connection when the function returns
    defer host.Close()

    // Create a list named "greetings"
    list, err := db.NewList(host, "greetings")
    if err != nil {
        log.Fatalln("Could not create list!")
    }

    // Add "hello" to the list, check if there are errors
    if list.Add("hello") != nil {
        log.Fatalln("Could not add an item to list!")
    }

    // Get the last item of the list
    if item, err := list.GetLast(); err != nil {
        log.Fatalln("Could not fetch the last item from the list!")
    } else {
        log.Println("The value of the stored item is:", item)
    }

    // Remove the list
    if list.Remove() != nil {
        log.Fatalln("Could not remove the list!")
    }
}

• A PostgreSQL server must be up and running locally for go test to work, and a database named test must exist.
