Datapages — Go web framework with code generation

⚙

Code Generation

Define your pages and handlers in pure Go code and let Datapages generate the server, routing, and middleware automatically.

🚀

Always in Sync

Not just a one-time scaffold. Every time you change your source package, Datapages regenerates routing, wiring, and helpers to stay coherent.

🔒

Built-In Linter

Catches naming violations, missing fields, and invalid handler signatures at generation time. Fix mistakes before they reach runtime.

⚡

Live Reload Dev Server

datapages watch rebuilds on file changes, regenerates code, and live-reloads the browser. No manual restarts.

📡

Real-Time SSE & CQRS

Dispatch events and handle them with OnXXX methods. Datapages wires up Server-Sent Events, NATS, and CQRS for you.

🔐

Auth & Security

Token-based sessions, automatic CSRF protection, and secure cookie management. Just declare session Session in your handler and let Datapages handle the rest.

What your code looks like

// PageProfile is /profile/{id}
type PageProfile struct{ App *App }

func (p PageProfile) GET(
    r *http.Request,
    session Session,
    path struct {
        ID string `path:"id"`
    },
) (body templ.Component, err error) {
    user, err := p.App.repo.FindUser(path.ID)
    if err != nil {
        return nil, err
    }
    return profilePage(user, session), nil
}

// POSTFollow is /profile/{id}/follow
func (p PageProfile) POSTFollow(
    r *http.Request,
    session Session,
    path struct {
        ID string `path:"id"`
    },
    dispatch func(EventUserFollowed) error,
) error {
    return dispatch(EventUserFollowed{TargetID: path.ID})
}

What Datapages generates

datapagesgen/app_gen.go

Server & Routing

HTTP mux with typed handlers, middleware chain, session cookie management, CSRF validation, error recovery, SSE stream handlers, and event broker wiring.

datapagesgen/href/href_gen.go

Type-Safe URLs

Functions like href.Profile("user-42") that return correct URL strings with path parameters filled in at compile time.

datapagesgen/action/action_gen.go

Type-Safe Actions

Helpers like action.ProfileFollow("user-42") for Datastar form actions with the right HTTP method and URL.
