Uni Ecto Plugin -

step = Ecto.delete(struct_or_changeset)

Traditional Phoenix contexts often mix concerns:

Ecto is the standard database wrapper and query generator for Elixir applications. While Ecto provides powerful primitives for managing schemas, changesets, and queries, larger applications often require reusable database logic. This is where the concept of custom Ecto plugins—frequently referred to in the ecosystem as custom extensions or "uni" (universal/unified) Ecto plugins—becomes essential.

Ecto returns :error, changeset . But what about validation errors vs. database constraint errors vs. connection errors? Uni normalizes all Ecto errors into a standard Uni.Error.t() structure. uni ecto plugin

: Applications that require real-time data processing and updates can benefit from the plugin's performance enhancements and streamlined database operations.

Even with UniEcto, your Context modules should remain the source of truth for business logic. Use UniEcto for (like refreshing a LiveView or clearing a cache), not for primary data validation. Monitor Your PubSub

:ok, prefix end

Because UniEcto makes broadcasting so easy, it’s tempting to broadcast everything. Monitor your Phoenix PubSub usage to ensure you aren't flooding your nodes with unnecessary messages, which can lead to increased memory usage.

Deleting rows permanently ( DELETE FROM ) can be dangerous. Soft deleting sets a timestamp instead. A Uni Ecto plugin can automate this globally. Automatically adds deleted_at . step = Ecto

This is where the plugin comes into play. If you are looking to streamline your workflow and bridge the gap between your database layer and real-time frontend updates, this guide is for you. What is UniEcto?

defmodule MyApp.Accounts.User do use Ecto.Schema import Ecto.Changeset # Inject plugin functionality use UniEctoPlugin use UniEctoPlugin.SoftDelete schema "users" do field :name, :string field :email, :string field :tracking_id, :string # Injected by UniEctoPlugin.SoftDelete macro # field :deleted_at, :utc_datetime timestamps() end def changeset(user, attrs) do user |> cast(attrs, [:name, :email]) |> validate_required([:name, :email]) # Pipe through the unified plugin lifecycle handler |> track_lifecycle() end end Use code with caution. 5. Performance and Best Practices

If you encounter older Ecto code (pre-version 0.16.0), you might come across validate_unique/3 . This function was deprecated in favor of unique_constraint/3 because it performed uniqueness checks by querying the database before insertion, which left the code vulnerable to race conditions. Ecto returns :error, changeset
