Connect to database

D3 uses wrappers on existing database drivers. Currently, available two PostgreSQL drivers for a single connection and for the connection pool (based on pgx) and SQLite driver (based on go-sqlite3).

This is an example of creating a drivers:

import (
	d3pgx "github.com/godzie44/d3/adapter/pgx"
	"github.com/godzie44/d3/adapter/sqlite"
	"github.com/jackc/pgx/v4"
)


// postgres driver
cfg, err := pgx.ParseConfig(os.Getenv("DB"))
if err != nil {
    log.Fatal(err)
}

driver, err := d3pgx.NewPgxDriver(cfg)
if err != nil {
    log.Fatal(err)
}

// postgres connection pool driver
cfg, err := pgxpool.ParseConfig(os.Getenv("DB"))
if err != nil {
	log.Fatal(err.Error())
}

driver, err := d3pgx.NewPgxPoolDriver(cfg)
if err != nil {
	log.Fatal(err.Error())
}

// sqlite driver
driver, err := sqlite.NewSQLiteDriver("./test.db")
if err != nil {
	log.Fatal(err.Error())
}
