Sending Data

    Hemlock tries its best to serialize data in the correct way, based on the data provided.

    Basic types are cast to strings.

    res.Data("string")  // string
    res.Data(1.24523)   // 1.24523
    res.Data(true)      // true

    Structs are serialized to JSON.

    type User struct {
    	Name string `json:"name"`
    res.Data(&User{Name: "Gregory"})
    // {"name": "Gregory"}

    Files (and all io.Readers) are streamed directly to the response.

    f, _ := os.Open("myfile.txt")


    Errors can be handled using the Error method. This will return a 500 response and render the default error page.

    f, err := os.Open("foo.txt")
    if err != nil {
        return res.Error(err)

    The default behavior can be overridden by setting things before calling Error.

    The following example overrides both status code and the response body so calling Error will only log the error.

    res.Status(400).Data("Bad Request").Error(err)

    Rendering Views

    Templates can be rendered using the Render method.

    res.View("name", "layout", map[string]string{"name": "Gregory"})

    The last two arguments are both optional.

    res.View("name", "", nil)



    	Name: "session_id",
    	Value: "123",
        Expires: time.Now().Add(time.Hour * 24 * 7),

    HTTP Headers

    Headers can be set using the Header method.

    res.Data(`{"foo": "bar"}`).Header("Content-Type", "application/json")
