GoAssistant-AI-powered tool for writing, coding, and more.

Example

Small, idiomatic handler with clear separation of concerns. Example (net/http style): func NewServer(svc UserService) http.Handler { r := http.NewServeMux() r.HandleFunc("/users/", makeListUsersHandler(svc)) return r } func makeListUsersHandler(svc UserService) http.HandlerFunc { return func(w http.ResponseWriter, r *http.Request) { users, err := svc.List(r.Context()) if err != nil { http.Error(w, "server error", http.StatusInternalServerError) return } tmpl.ExecuteTemplate(w, "users.html", users) // server-rendered page } } The same service interface used above makes testing straightforward because you can inject a mock UserService.

Scenario

Building a medium-sized internal tool that needs a REST-ish API and server-rendered pages. GoAssistant will propose the service/handler/template split, show how to wire a router (chi/mux/net/http), suggest request context usage for timeouts and tracing, and provide example tests for the service layer and a small integration test for the handler.

Example

HTMX pattern for partial updates (client HTML + server fragment): <!-- client page: list.html --> <button class="btn" hx-get="/tasks/42/edit" hx-swap="outerHTML">Edit</button> // server handler returns only the fragment for the single row <form hx-post="/tasks/42" hx-swap="outerHTML"> <input name="title" value="Existing title" /> <button type="submit">Save</button> </form> Server-side: render the edit template and return that fragment as the response. On success, return the updated row HTML so HTMX replaces the row immediately.

Scenario

You want an interactive admin table (inline edits, quick deletes, paginated load-more) without React/Vue. GoAssistant will provide HTMX attributes design (hx-get, hx-post, hx-trigger, hx-target, hx-boost), server behavior (when to return full page vs fragment), error-handling strategies (use hx-swap with swap-oob for notifications), and accessibility considerations (focus management after swaps).

Example

Multi-stage Dockerfile (concise example): # builder FROM golang:1.20 AS builder WORKDIR /src COPY go.mod go.sum ./ RUN go mod download COPY . . RUN CGO_ENABLED=0 GOOS=linux go build -o /app ./cmd/web # final image FROM gcr.io/distroless/static COPY --from=builder /app /app ENTRYPOINT ["/app"] CI snippet (github-actions): run go vet, golangci-lint, go test -race, and build/publish image in separate steps.

Scenario

Preparing a microservice for production: GoAssistant will recommend CI steps (lint, test, build), automated vulnerability scanning, health endpoints, graceful shutdown patterns (context cancellation), pprof endpoints behind auth for profiling, simple observability (structured logging, basic Prometheus metrics), and a deployment checklist (secrets, readiness/liveness probes, resource limits). It can also review PR diffs and suggest concrete improvements (reduce allocations, avoid unnecessary goroutines, fix data races).
