+```go +f.Get("/", handler) // Root +f.Get("/", handler) // Basic param +f.Get("//", handler) // Multiple params +f.Get("/", handler) // Regex +``` + +## Handler Signatures + +### Basic Handler + +**Macaron:** +```go +func Handler(c *macaron.Context) { + c.JSON(200, map[string]string{"msg": "hello"}) +} +``` + +**Flamego:** +```go +func Handler(c flamego.Context) { +

+**Macaron:** +```go +m.Use(session.Sessioner(session.Options{ + Provider: "memory", + ProviderConfig: "", + CookieName: "session_id", + CookiePath: "/", + Gclifetime: 3600, + Maxlifetime: 3600, +}))

+``` + +**Flamego:** +```go +f.Use(csrf.Csrfer(csrf.Options{ + Secret: "secret-key", + Cookie: "_csrf", + CookiePath: "/", + Secure: false, +})) +``` + +### Cache + +**Macaron:** +```go

Pattern: Get User by Username + +**Macaron:** +```go +func UserProfile(c *context.Context) { + username := c.Params(":username") + user, err := database.GetUserByName(username) + if err != nil { + c.NotFoundOrError(err, "get user") + return + } + c.Data["User"] = user + c.HTML(200, "user/profile") +} +``` + +**Flamego:** +```go +func UserProfile(c *context.Context, t template.Template, data

t.HTML(200, "user/profile") +} +``` + +### Pattern: Form Submission + +**Macaron:** +```go +// Form struct +type CreateRepoForm struct { + Name string `form:"name" binding:"Required;AlphaDashDot"` +} + +// Route +m.Post("/repo/create", binding.Bind(CreateRepoForm{}), CreateRepoPost) + +// Handler +func CreateRepoPost(c *context.Context, form CreateRepoForm) { + if c.HasError() { + c.RenderWithErr(c.GetErrMsg(), "repo/create", &form) + return + } + // Create repo... + c.Redirect("/") +} +``` + +**Flamego:** +```go +// Form struct +type CreateRepoForm struct { + Name string `form:"name" validate:"required,alphaDashDot"` +} + +// Route +f.Post("/repo/create", binding.Form(CreateRepoForm{}), CreateRepoPost) + +// Handler +func CreateRepoPost(c *context.Context, form CreateRepoForm, t template.Template, data template.Data) { + if c.HasError() { + c.RenderWithErr(c.GetErrMsg(), "repo/create", &form, t, data) + return + } + // Create repo... + c.Redirect("/") +} +``` + +### Pattern: JSON API + +**Macaron:** +```go +func APIHandler(c *context.APIContext) { + data := map[string]any{ + "id": 123, + "name": "example", + } + c.JSON(200, data) +} +``` + +**Flamego:** +```go +func APIHandler(c *context.APIContext) { + data := map[string]any{ + "id": 123, + "name": "example", + } + + c.ResponseWriter().Header().Set("Content-Type", "application/json") + c.ResponseWriter().WriteHeader(200) + json.NewEncoder(c.ResponseWriter()).Encode(data) +} + +// Or create helper method on APIContext +func (c *APIContext) JSON(status int, v any) error { + c.ResponseWriter().Header().Set("Content-Type", "application/json") + c.ResponseWriter().WriteHeader(status) + return json.NewEncoder(c.ResponseWriter()).Encode(v) +} +``` + +### Pattern: Middleware Chain + +**Macaron:** +```go +m.Group("/repo", func() { + m.Get("/create", repo.Create) + m.Post("/create", binding.Bind(form.CreateRepo{}), repo.CreatePost) +}, reqSignIn, context.RepoAssignment()) +``` + +**Flamego:** +```go +f.Group("/repo", func() { + f.Get("/create", repo.Create) + f.Post("/create", binding.Form(form.CreateRepo{}), repo.CreatePost) +}, reqSignIn, context.RepoAssignment()) +``` + +## Error Handling + +### Not Found + +**Macaron:** +```go +func Handler(c *context.Context) { + user, err := getUser() + if err != nil { + if isNotFound(err) { + c.NotFound() + return + } + c.Error(err, "get user") + return + } +} +``` + +**Flamego:** +```go +func Handler(c *context.Context) { + user, err := getUser() + if err != nil { + if isNotFound(err) { + c.NotFound() + return + } + c.Error(err, "get user") + return + } +} +``` + +## Testing + +### Mock Context + +**Macaron:** +```go +import "gopkg.in/macaron.v1" + +func TestHandler(t *testing.T) { + m := macaron.New() + req, _ := http.NewRequest("GET", "/", nil) + resp := httptest.NewRecorder() + m.ServeHTTP(resp, req) +} +``` + +**Flamego:** +```go +import "github.com/flamego/flamego" + +func TestHandler(t *testing.T) { + f := flamego.New() + req, _ := http.NewRequest("GET", "/", nil) + resp := httptest.NewRecorder() + f.ServeHTTP(resp, req) +} +``` + +## Migration Checklist (Quick) + +- [ ] Update imports +- [ ] Change `:param` → `` in routes +- [ ] Change `macaron.Handler` → `flamego.Handler` +- [ ] Change `*macaron.Context` → `flamego.Context` +- [ ] Change `c.Params(":name")` → `c.Param("name")` +- [ ] Change `c.Resp` → `c.ResponseWriter()` +- [ ] Change `c.Req` → `c.Request()` +- [ ] Change `session.Store` → `session.Session` +- [ ] Change `x.GetToken()` → `x.Token()` +- [ ] Change `cache.Put()` → `cache.Set()` +- [ ] Add template parameters to handlers +- [ ] Update form validation tags +- [ ] Test everything! + +## Common Pitfalls + +| Issue | Solution | +|-------|----------| +| Forgot to remove `:` from param name | Use `c.Param("name")` not `c.Param(":name")` | +| Template not rendering | Add `template.Template` and `template.Data` to handler | +| Session not working | Changed interface from `Store` to `Session` | +| CSRF validation fails | Use `Token()` not `GetToken()` | +| Cache not working | Use `Set()` not `Put()` | +| Form validation errors | Update tags: `binding` → `validate` | +| Context methods fail | Use methods not fields: `c.ResponseWriter()` not `c.Resp` | + +## Performance Notes + +### Flamego Advantages + +1. **O(1) static route lookup** - Faster than Macaron's tree +2. **Better regex handling** - Compiled patterns cached +3. **Reduced allocations** - More efficient memory usage +4. **Faster middleware chain** - Optimized injection + +### Expected Improvements + +- 10-30% faster route matching for static routes +- 5-15% faster overall request handling +- Slightly lower memory usage +- Better scalability under load + +## Support and Resources +
