preá.goA modular web framework for Go

Split your app into small preás. Declare what each one needs, and Preá wires it, checks it and serves it.

Get started

Build a todo API

GitHub

🧩

One feature, one preá

A preá keeps a feature together, from its routes to its rules and its table. Your app is the list of its preás.

🔌

Ask, and it is wired

Tag a field with inject:"" and Preá fills it at startup. A missing dependency stops the app before it serves a single request.

🗄️

Your models are the schema

Struct tags describe the tables. Preá writes the migrations, applies them and gives every model a ready-made repository.

⚙️

One file per environment

A base configuration plus one file for dev, prod and tests. Secrets come from the environment, never from the repository.

🛡️

Safe defaults

CORS, CSRF protection, security headers, timeouts and a graceful shutdown come configured in every new project.

🚀

A CLI for the whole cycle

prea new, prea dev with hot reload, generators, migrations, tests and builds, all from the same command.

From zero to a running API

bash

curl -fsSL https://raw.githubusercontent.com/prea-framework/prea/main/install.sh | sh

prea new todo --with-db
cd todo
prea dev

A preá is a few plain Go files. You declare its components, and every component asks for what it needs:

var Module = &core.Module{
	Name:      "task",
	Providers: []any{Repository{}, Service{}, Handler{}},
}

type Service struct {
	Repo *Repository `inject:""` // Preá fills this when the app starts
}
