### RFC 9457 Problem Details Example

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Illustrates the structured RFC 9457 Problem Details format for API errors, providing consistency over ad-hoc responses.

```json
{
  "type": "...",
  "title": "...",
  "status": 400,
  "detail": "..."
}
```

--------------------------------

### Curl Command for Core Request Parsing

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Example cURL command to test the /users/{id} endpoint created with the core request parsing snippet.

```bash
curl -X POST http://localhost:8080/users/123 \
  -H "Content-Type: application/json" \
  -d '{"name":"Ada"}'
```

--------------------------------

### Global Validator Configuration

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Configures a global validator for request parsing using a custom validator implementation. This setup enables automatic validation for all subsequent ParseRequest calls.

```go
validator := playground.NewWithValidator(nil, &httpsuite.ProblemConfig{
	BaseURL: "https://api.example.com",
})

httpsuite.SetValidator(validator)

req, err := httpsuite.ParseRequest[*CreateUserRequest](
	w,
	r,
	chi.URLParam,
	&httpsuite.ParseOptions{
		MaxBodyBytes: 1 << 20,
	},
	"id",
)
```

--------------------------------

### Simplified Request Handling With httpsuite

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Demonstrates the concise and safer way to handle HTTP requests using httpsuite, consolidating parsing, binding, and response logic.

```go
req, err := httpsuite.ParseRequest[*MyRequest](w, r, chi.URLParam, nil, "id")
if err != nil {
    return
}

httpsuite.OK(w, req)
```

--------------------------------

### Problem Builder and Response

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Demonstrates building a custom problem response using a builder pattern. This allows for detailed configuration of problem types, titles, details, and instances before writing the response.

```go
problem := httpsuite.Problem(http.StatusNotFound).
	Type(httpsuite.GetProblemTypeURL("not_found_error")),
	Title("User Not Found").
	Detail("user 42 does not exist").
	Instance("/users/42").
	Build()

httpsuite.RespondProblem(problem).
	Header("X-Trace-ID", traceID).
	Write(w)
```

--------------------------------

### Direct Response Helpers

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Provides direct helper functions for common HTTP responses like OK, Created, and Problem responses. These are useful for simple, straightforward response generation.

```go
httpsuite.OK(w, user)
httpsuite.OKWithMeta(w, users, httpsuite.NewPageMeta(page, pageSize, totalItems))
httpsuite.Created(w, user, "/users/42")
httpsuite.ProblemResponse(w, httpsuite.NewNotFoundProblem("user not found"))
```

--------------------------------

### Manual Request Handling Without httpsuite

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Shows the traditional, more verbose approach to handling HTTP requests in Go without using a library like httpsuite. This often involves manual JSON decoding, path parameter parsing, and error handling.

```go
var req MyRequest

if err := json.NewDecoder(r.Body).Decode(&req); err != nil {
    http.Error(w, "invalid body", 400)
    return
}

idStr := chi.URLParam(r, "id")
id, err := strconv.Atoi(idStr)
if err != nil {
    http.Error(w, "invalid id", 400)
    return
}

// validation...
// more error handling...
```

--------------------------------

### Advanced Problem Response Builder

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Demonstrates the advanced builder pattern for constructing custom RFC 9457 Problem responses.

```go
httpsuite.Problem(...).Title(...).Build()
```

--------------------------------

### Parse Request with Path Parameter Binding

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Parses a request body, binds path parameters, and optionally performs validation. Use this for a consolidated request handling flow.

```go
req, err := httpsuite.ParseRequest[*MyRequest](w, r, chi.URLParam, nil, "id")
if err != nil {
    return
}
```

--------------------------------

### Simple Success Response

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Uses a direct helper to send a simple success response with data.

```go
httpsuite.OK(w, data)
```

--------------------------------

### Fluent Success Response with Metadata

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Uses a fluent API to construct a success response, including optional generic metadata.

```go
httpsuite.Reply().Meta(meta).OK(w, data)
```

--------------------------------

### Fluent Response Builders

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Offers a fluent API for constructing HTTP responses, allowing chaining of methods for setting metadata, headers, and response bodies. This provides a more readable and composable way to build responses.

```go
httpsuite.Reply().
	Meta(httpsuite.NewPageMeta(page, pageSize, totalItems)).
	OK(w, users)

httpsuite.Reply().
	Header("X-Request-ID", requestID).
	Created(w, user, "/users/42")
```

--------------------------------

### Core Request Parsing with Chi

Source: https://github.com/rluders/httpsuite/blob/main/README.md

Parses an incoming HTTP request into a strongly-typed Go struct using the 'chi' router. It demonstrates how to extract URL parameters and handle potential parsing errors.

```go
package main

import (
	"net/http"
	"strconv"

	"github.com/go-chi/chi/v5"
	"github.com/rluders/httpsuite/v3"
)

type CreateUserRequest struct {
	ID   int    `json:"id"`
	Name string `json:"name"`
}

func (r *CreateUserRequest) SetParam(fieldName, value string) error {
	if fieldName != "id" {
		return nil
	}

	id, err := strconv.Atoi(value)
	if err != nil {
		return err
	}
	r.ID = id
	return nil
}

func main() {
	router := chi.NewRouter()

	router.Post("/users/{id}", func(w http.ResponseWriter, r *http.Request) {
		req, err := httpsuite.ParseRequest[*CreateUserRequest](w, r, chi.URLParam, nil, "id")
		if err != nil {
			return
		}

		httpsuite.OK(w, req)
	})

	_ = http.ListenAndServe(":8080", router)
}
```
