# Render [](http://godoc.org/github.com/unrolled/render) [](https://travis-ci.org/unrolled/render) |
||||
|
||||
Render is a package that provides functionality for easily rendering JSON, XML, text, binary data, and HTML templates. This package is based on the [Martini](https://github.com/go-martini/martini) [render](https://github.com/martini-contrib/render) work. |
||||
|
||||
## Block Deprecation Notice |
||||
Go 1.6 introduces a new [block](https://github.com/golang/go/blob/release-branch.go1.6/src/html/template/example_test.go#L128) action. This conflicts with Render's included `block` template function. To provide an easy migration path, a new function was created called `partial`. It is a duplicate of the old `block` function. It is advised that all users of the `block` function update their code to avoid any issues in the future. Previous to Go 1.6, Render's `block` functionality will continue to work but a message will be logged urging you to migrate to the new `partial` function. |
||||
|
||||
## Usage |
||||
Render can be used with pretty much any web framework providing you can access the `http.ResponseWriter` from your handler. The rendering functions simply wraps Go's existing functionality for marshaling and rendering data. |
||||
|
||||
- HTML: Uses the [html/template](http://golang.org/pkg/html/template/) package to render HTML templates. |
||||
- JSON: Uses the [encoding/json](http://golang.org/pkg/encoding/json/) package to marshal data into a JSON-encoded response. |
||||
- XML: Uses the [encoding/xml](http://golang.org/pkg/encoding/xml/) package to marshal data into an XML-encoded response. |
||||
- Binary data: Passes the incoming data straight through to the `http.ResponseWriter`. |
||||
- Text: Passes the incoming string straight through to the `http.ResponseWriter`. |

### Available Options |
||||
Render comes with a variety of configuration options _(Note: these are not the default option values. See the defaults below.)_: |
||||
|
||||
~~~ go |
||||
// ... |
||||
r := render.New(render.Options{ |
||||
Directory: "templates", // Specify what path to load the templates from. |
||||
FileSystem: &LocalFileSystem{}, // Specify filesystem from where files are loaded. |
||||
Asset: func(name string) ([]byte, error) { // Load from an Asset function instead of file. |
||||
return []byte("template content"), nil |
||||
}, |
||||
AssetNames: func() []string { // Return a list of asset names for the Asset function |
||||
return []string{"filename.tmpl"} |
||||
}, |
||||
Layout: "layout", // Specify a layout template. Layouts can call {{ yield }} to render the current template or {{ partial "css" }} to render a partial from the current template. |
||||
Extensions: []string{".tmpl", ".html"}, // Specify extensions to load for templates. |
||||
Funcs: []template.FuncMap{AppHelpers}, // Specify helper function maps for templates to access. |
||||
Delims: render.Delims{"{[{", "}]}"}, // Sets delimiters to the specified strings. |
||||
Charset: "UTF-8", // Sets encoding for content-types. Default is "UTF-8". |
||||
DisableCharset: true, // Prevents the charset from being appended to the content type header. |
||||
IndentJSON: true, // Output human readable JSON. |
||||
IndentXML: true, // Output human readable XML. |
||||
PrefixJSON: []byte(")]}',\n"), // Prefixes JSON responses with the given bytes. |
||||
PrefixXML: []byte("<?xml version='1.0' encoding='UTF-8'?>"), // Prefixes XML responses with the given bytes. |
||||
HTMLContentType: "application/xhtml+xml", // Output XHTML content type instead of default "text/html". |
||||
IsDevelopment: true, // Render will now recompile the templates on every HTML response. |
||||
UnEscapeHTML: true, // Replace ensure '&<>' are output correctly (JSON only). |
||||
StreamingJSON: true, // Streams the JSON response via json.Encoder. |
||||
RequirePartials: true, // Return an error if a template is missing a partial used in a layout. |
||||
DisableHTTPErrorRendering: true, // Disables automatic rendering of http.StatusInternalServerError when an error occurs. |
||||
}) |
||||
// ... |
||||
~~~ |
||||
|
||||
### Default Options |
||||
These are the preset options for Render: |
||||
|
||||
~~~ go |
||||
r := render.New() |
||||
|
||||
// Is the same as the default configuration options: |
||||
|
||||
r := render.New(render.Options{ |
||||
Directory: "templates", |
||||
FileSystem: &LocalFileSystem{}, |
||||
Asset: nil, |
||||
AssetNames: nil, |
||||
Layout: "", |
||||
Extensions: []string{".tmpl"}, |
||||
Funcs: []template.FuncMap{}, |
||||
Delims: render.Delims{"{{", "}}"}, |
||||
Charset: "UTF-8", |
||||
DisableCharset: false, |
||||
IndentJSON: false, |
||||
IndentXML: false, |
||||
PrefixJSON: []byte(""), |
||||
PrefixXML: []byte(""), |
||||
BinaryContentType: "application/octet-stream", |
||||
HTMLContentType: "text/html", |
||||
JSONContentType: "application/json", |
||||
JSONPContentType: "application/javascript", |
||||
TextContentType: "text/plain", |
||||
XMLContentType: "application/xhtml+xml", |
||||
IsDevelopment: false, |
||||
UnEscapeHTML: false, |
||||
StreamingJSON: false, |
||||
RequirePartials: false, |
||||
DisableHTTPErrorRendering: false, |
||||
}) |
||||
~~~ |
||||
|
||||
### JSON vs Streaming JSON |
||||
By default, Render does **not** stream JSON to the `http.ResponseWriter`. It instead marshalls your object into a byte array, and if no errors occurred, writes that byte array to the `http.ResponseWriter`. If you would like to use the built it in streaming functionality (`json.Encoder`), you can set the `StreamingJSON` setting to `true`. This will stream the output directly to the `http.ResponseWriter`. Also note that streaming is only implemented in `render.JSON` and not `render.JSONP`, and the `UnEscapeHTML` and `Indent` options are ignored when streaming. |
||||
|
||||
### Loading Templates |
||||
By default Render will attempt to load templates with a '.tmpl' extension from the "templates" directory. Templates are found by traversing the templates directory and are named by path and basename. For instance, the following directory structure: |
||||
|
||||
~~~ |
||||
templates/ |
||||
| |
||||
|__ admin/ |
||||
| | |
||||
| |__ index.tmpl |
||||
| | |
||||
| |__ edit.tmpl |
||||
| |
||||
|__ home.tmpl |
||||
~~~ |
||||
|
||||
Will provide the following templates: |
||||
~~~ |
||||
admin/index |
||||
admin/edit |
||||
home |
||||
~~~ |
||||
|
||||
You can also load templates from memory by providing the Asset and AssetNames options, |
||||
e.g. when generating an asset file using [go-bindata](https://github.com/jteeuwen/go-bindata). |
||||
|
||||
### Layouts |
||||
Render provides `yield` and `partial` functions for layouts to access: |
||||
~~~ go |
||||
// ... |
||||
r := render.New(render.Options{ |
||||
Layout: "layout", |
||||
}) |
||||
// ... |
||||
~~~ |
||||
|
||||
~~~ html |
||||
<!-- templates/layout.tmpl --> |
||||
<html> |
||||
<head> |
||||
<title>My Layout</title> |
||||
<!-- Render the partial template called `css-$current_template` here --> |
||||
{{ partial "css" }} |
||||
</head> |
||||
<body> |
||||
<!-- render the partial template called `header-$current_template` here --> |
||||
{{ partial "header" }} |
||||
<!-- Render the current template here --> |
||||
{{ yield }} |
||||
<!-- render the partial template called `footer-$current_template` here --> |
||||
{{ partial "footer" }} |
||||
</body> |
||||
</html> |
||||
~~~ |
||||
|
||||
`current` can also be called to get the current template being rendered. |
||||
~~~ html |
||||
<!-- templates/layout.tmpl --> |
||||
<html> |
||||
<head> |
||||
<title>My Layout</title> |
||||
</head> |
||||
<body> |
||||
This is the {{ current }} page. |
||||
</body> |
||||
</html> |
||||
~~~ |
||||
|
||||
Partials are defined by individual templates as seen below. The partial template's |
||||
name needs to be defined as "{partial name}-{template name}". |
||||
~~~ html |
||||
<!-- templates/home.tmpl --> |
||||
{{ define "header-home" }} |
||||
<h1>Home</h1> |
||||
{{ end }} |
||||
|
||||
{{ define "footer-home"}} |
||||
<p>The End</p> |
||||
{{ end }} |
||||
~~~ |
||||
|
||||
By default, the template is not required to define all partials referenced in the |
||||
layout. If you want an error to be returned when a template does not define a |
||||
partial, set `Options.RequirePartials = true`. |
||||
|
||||
### Character Encodings |
||||
Render will automatically set the proper Content-Type header based on which function you call. See below for an example of what the default settings would output (note that UTF-8 is the default, and binary data does not output the charset): |
||||
~~~ go |
||||
// main.go |
||||
package main |
||||
|
||||
import ( |
||||
"encoding/xml" |
||||
"net/http" |
||||
|
||||
"github.com/unrolled/render" // or "gopkg.in/unrolled/render.v1" |
||||
) |
||||
|
||||
type ExampleXml struct { |
||||
XMLName xml.Name `xml:"example"` |
||||
One string `xml:"one,attr"` |
||||
Two string `xml:"two,attr"` |
||||
} |
||||
|
||||
func main() { |
||||
r := render.New(render.Options{}) |
||||
mux := http.NewServeMux() |
||||
|
||||
// This will set the Content-Type header to "application/octet-stream". |
||||
// Note that this does not receive a charset value. |
||||
mux.HandleFunc("/data", func(w http.ResponseWriter, req *http.Request) { |
||||
r.Data(w, http.StatusOK, []byte("Some binary data here.")) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "application/json; charset=UTF-8". |
||||
mux.HandleFunc("/json", func(w http.ResponseWriter, req *http.Request) { |
||||
r.JSON(w, http.StatusOK, map[string]string{"hello": "json"}) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/xml; charset=UTF-8". |
||||
mux.HandleFunc("/xml", func(w http.ResponseWriter, req *http.Request) { |
||||
r.XML(w, http.StatusOK, ExampleXml{One: "hello", Two: "xml"}) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/plain; charset=UTF-8". |
||||
mux.HandleFunc("/text", func(w http.ResponseWriter, req *http.Request) { |
||||
r.Text(w, http.StatusOK, "Plain text here") |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/html; charset=UTF-8". |
||||
mux.HandleFunc("/html", func(w http.ResponseWriter, req *http.Request) { |
||||
// Assumes you have a template in ./templates called "example.tmpl" |
||||
// $ mkdir -p templates && echo "<h1>Hello {{.}}.</h1>" > templates/example.tmpl |
||||
r.HTML(w, http.StatusOK, "example", "World") |
||||
}) |
||||
|
||||
http.ListenAndServe("127.0.0.1:3000", mux) |
||||
} |
||||
~~~ |
||||
|
||||
In order to change the charset, you can set the `Charset` within the `render.Options` to your encoding value: |
||||
~~~ go |
||||
// main.go |
||||
package main |
||||
|
||||
import ( |
||||
"encoding/xml" |
||||
"net/http" |
||||
|
||||
"github.com/unrolled/render" // or "gopkg.in/unrolled/render.v1" |
||||
) |
||||
|
||||
type ExampleXml struct { |
||||
XMLName xml.Name `xml:"example"` |
||||
One string `xml:"one,attr"` |
||||
Two string `xml:"two,attr"` |
||||
} |
||||
|
||||
func main() { |
||||
r := render.New(render.Options{ |
||||
Charset: "ISO-8859-1", |
||||
}) |
||||
mux := http.NewServeMux() |
||||
|
||||
// This will set the Content-Type header to "application/octet-stream". |
||||
// Note that this does not receive a charset value. |
||||
mux.HandleFunc("/data", func(w http.ResponseWriter, req *http.Request) { |
||||
r.Data(w, http.StatusOK, []byte("Some binary data here.")) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "application/json; charset=ISO-8859-1". |
||||
mux.HandleFunc("/json", func(w http.ResponseWriter, req *http.Request) { |
||||
r.JSON(w, http.StatusOK, map[string]string{"hello": "json"}) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/xml; charset=ISO-8859-1". |
||||
mux.HandleFunc("/xml", func(w http.ResponseWriter, req *http.Request) { |
||||
r.XML(w, http.StatusOK, ExampleXml{One: "hello", Two: "xml"}) |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/plain; charset=ISO-8859-1". |
||||
mux.HandleFunc("/text", func(w http.ResponseWriter, req *http.Request) { |
||||
r.Text(w, http.StatusOK, "Plain text here") |
||||
}) |
||||
|
||||
// This will set the Content-Type header to "text/html; charset=ISO-8859-1". |
||||
mux.HandleFunc("/html", func(w http.ResponseWriter, req *http.Request) { |
||||
// Assumes you have a template in ./templates called "example.tmpl" |
||||
// $ mkdir -p templates && echo "<h1>Hello {{.}}.</h1>" > templates/example.tmpl |
||||
r.HTML(w, http.StatusOK, "example", "World") |
||||
}) |
||||
|
||||
http.ListenAndServe("127.0.0.1:3000", mux) |
||||
} |
||||
~~~ |
||||
|
||||
### Error Handling |
||||
|
||||
The rendering functions return any errors from the rendering engine. |
||||
By default, they will also write the error to the HTTP response and set the status code to 500. You can disable |
||||
this behavior so that you can handle errors yourself by setting |
||||
`Options.DisableHTTPErrorRendering: true`. |
||||
|
||||
~~~go |
||||
r := render.New(render.Options{ |
||||
DisableHTTPErrorRendering: true, |
||||
}) |
||||
|
||||
//... |
||||
|
||||
err := r.HTML(w, http.StatusOK, "example", "World") |
||||
if err != nil{ |
||||
http.Redirect(w, r, "/my-custom-500", http.StatusFound) |
||||
} |
||||
