Provides a Go API for interactive maps within Via applications:
- Plugin serves vendored MapLibre GL JS v4.7.1 assets
- Map struct with pre/post-render source, layer, marker, popup management
- Viewport signal sync (center, zoom, bearing, pitch) via hidden inputs
- FlyTo, SetCenter, SetZoom and other viewport setters via ExecScript
- Idempotent init script with SPA cleanup via MutationObserver
- Example app demonstrating markers, GeoJSON layers, and FlyTo actions
Streams listed in Options.Streams are created by Start() when the
embedded NATS server initializes, replacing manual EnsureStream calls
during setup. Migrates nats-chatroom and pubsub-crud examples.
Extract chat, profile, types, and user data into separate files.
Embed CSS via go:embed. Add a layout with nav, session-based profile
persistence, and a middleware guard that redirects to /profile when
no identity is set.
Swap page content over the existing SSE connection without full page
loads. A persistent Context resets its page-specific state (signals,
actions, intervals, subscriptions) on navigate while preserving the
SSE stream, CSRF token, and session.
- c.Navigate(path) for programmatic SPA navigation from actions
- Injected JS intercepts same-origin <a> clicks (opt out with
data-via-no-boost) and handles popstate for back/forward
- v.Layout() wraps pages in a shared shell for DRY nav/chrome
- View Transition API integration via WithViewTransitions() on
PatchElements and h.DataViewTransition() helper
- POST /_navigate endpoint with CSRF validation and rate limiting
- pageStopChan cancels page-level OnInterval goroutines on navigate
- Includes SPA example with layout, counter, and live clock pages
Replace the exported OnIntervalRoutine struct (Start/Stop/UpdateInterval)
with a single function that auto-starts the goroutine and returns an
idempotent stop closure. Uses close(channel) instead of send-on-channel,
fixing a potential deadlock when the goroutine exits via context disposal.
Closes#5 item 4.
Pub/sub now works out of the box — New() starts a process-scoped
embedded NATS server with JetStream. The PubSub interface remains
for custom backends via Config(Options{PubSub: ...}).
- Move vianats functionality into nats.go (eliminates circular import)
- Add NATSConn(), JetStream(), EnsureStream(), ReplayHistory[T]() to via
- Delete vianats/ package
- Simplify nats-chatroom and pubsub-crud examples
- Rewrite pubsub tests to use real embedded NATS
Fields created via Context.Field are now tracked on the page context,
so ValidateAll() and ResetFields() with no arguments operate on all
fields by default. Explicit field args still work for selective use.
Also switches MinLen/MaxLen to utf8.RuneCountInString for correct
unicode handling and replaces fmt.Errorf with errors.New where
format strings are unnecessary.
Introduces Field, Rule, ValidateAll, ResetFields, and AddError for
declarative input validation. Includes built-in rules (Required,
MinLen, MaxLen, Min, Max, Email, Pattern, Custom) and a signup
example exercising the full API surface.
* feat: add middleware example demonstrating route groups
Self-contained example covering v.Use(), v.Group(), nested groups,
Group.Use(), and middleware chaining with role-based access control.
* feat: add per-action middleware via WithMiddleware ActionOption
Reuses the existing Middleware type so the same auth/logging functions
work at both page and action level. Middleware runs after CSRF and
rate-limit checks, with full access to session and signals.
* feat: add RedirectView helper and refactor session example to use middleware
RedirectView lets middleware abort and redirect in one step. The session
example now uses an authRequired middleware on a route group instead of
an inline check inside the view.
* fix: remove dead code, fix double Load and extractParams mismatch
- Remove componentRegistry (written, never read)
- Remove unused signal methods: Bytes, Int64, Float
- Remove unreachable nil check in registerCtx
- Simplify injectRouteParams (extractParams already returns fresh map)
- Fix double sync.Map.Load in injectSignals
- Merge Shutdown/shutdown into single method
- Inline currSessionNum
- Fix extractParams: mismatched literal segment now returns nil
- Minor: new(bytes.Buffer), go c.Sync(), genRandID reads 4 bytes
Add typed Publish[T] and Subscribe[T] generic helpers that handle
JSON marshaling, along with vianats.EnsureStream and ReplayHistory
helpers. Refactor nats-chatroom to use the new APIs.
Add pubsub-crud example demonstrating CRUD operations with DaisyUI
toast notifications broadcast to all connected clients via NATS.
Switch from the standard library log package to rs/zerolog with
ConsoleWriter for colorful terminal output in dev mode and JSON
output in production. Users can now provide their own logger via
Options.Logger or set the level via Options.LogLevel.
Define PubSub and Subscription interfaces in the core via package with
a vianats sub-package providing the embedded NATS + JetStream
implementation. Expose c.Publish() and c.Subscribe() on Context with
automatic subscription cleanup on session close. Refactor the NATS
chatroom example to use the built-in methods instead of manual
subscription tracking.
Demonstrates pub/sub messaging as an alternative to custom Rooms
implementation. Uses delaneyj/toolbelt/embeddednats to run NATS
with JetStream inside the binary - no external server required.
Add NewSQLiteSessionManager helper that creates an SCS session manager
backed by SQLite, allowing sessions to persist across server restarts.
The function handles table creation automatically.
Add SSE-based navigation methods to Context:
- Redirect(url) / Redirectf() - navigate to new page
- ReplaceURL(url) / ReplaceURLf() - update URL without navigation
Update session example to demonstrate full login flow with redirects.
* Remove unused method. Don't panic if unknown room.
* Need a Connected() check for rooms publishing - don't do the work of rendering for a dead connection
* Make vars private.
* Linter issues
* Remove Connected()
* Mutation observer. Publish 4x / second.
