Todo app (end-to-end)

This minimal example declares a model, bootstraps SQLite and reads/writes tenant-scoped. The same file runs unchanged against orm.Yugabyte(dsn) in a geo-partitioned cluster.

package main

import (
  "context"
  orm "gitlab.techeve.de/techeve/orm-plus-plus"
)

type Todo struct {
  ID    orm.ID `orm:"pk"`
  Title string `orm:"index"`
  Done  bool
}

func main() {
  ctx := context.Background()

  db, err := orm.Open(orm.SQLite("./todo.db"))
  if err != nil { panic(err) }
  defer db.Close()

  orm.Register[Todo](db, orm.CRUD())
  if err := db.Migrate(ctx); err != nil { panic(err) }
  db.StartWorkers(ctx)

  ctx = orm.WithTenant(ctx, orm.SingleTenant)

  todos := orm.Repo[Todo](db)
  t := &Todo{Title: "build ORM++"}
  _ = todos.Insert(ctx, t)

  open, _ := todos.Query(ctx).Where(orm.Eq("Done", false)).All()
  _ = open
}

From CRUD to event sourcing

If Todo becomes an aggregate with history, only the declaration changes — the operational logic (Migrate/StartWorkers) stays the same. See Event sourcing.
