# Changelog
## v1.5.1 (2020-12-06)
- Performance improvement: removing 1 allocation by foregoing context.WithValue, thank you @bouk for
your contribution (https://github.com/go-chi/chi/pull/555). Note: new benchmarks posted in README.
- `middleware.CleanPath`: new middleware that clean's request path of double slashes
- deprecate & remove `chi.ServerBaseContext` in favour of stdlib `http.Server#BaseContext`
- plus other tiny improvements, see full commit history below
- History of changes: see https://github.com/go-chi/chi/compare/v4.1.2...v1.5.1
## v1.5.0 (2020-11-12) - now with go.mod support
`chi` dates back to 2016 with it's original implementation as one of the first routers to adopt the newly introduced
context.Context api to the stdlib -- set out to design a router that is faster, more modular and simpler than anything
else out there -- while not introducing any custom handler types or dependencies. Today, `chi` still has zero dependencies,
and in many ways is future proofed from changes, given it's minimal nature. Between versions, chi's iterations have been very
incremental, with the architecture and api being the same today as it was originally designed in 2016. For this reason it
makes chi a pretty easy project to maintain, as well thanks to the many amazing community contributions over the years
to who all help make chi better (total of 86 contributors to date -- thanks all!).
Chi has been an labour of love, art and engineering, with the goals to offer beautiful ergonomics, flexibility, performance
and simplicity when building HTTP services with Go. I've strived to keep the router very minimal in surface area / code size,
and always improving the code wherever possible -- and as of today the `chi` package is just 1082 lines of code (not counting
middlewares, which are all optional). As well, I don't have the exact metrics, but from my analysis and email exchanges from
companies and developers, chi is used by thousands of projects around the world -- thank you all as there is no better form of
joy for me than to have art I had started be helpful and enjoyed by others. And of course I use chi in all of my own projects too :)
For me, the asthetics of chi's code and usage are very important. With the introduction of Go's module support
(which I'm a big fan of), chi's past versioning scheme choice to v2, v3 and v4 would mean I'd require the import path
of "github.com/go-chi/chi/v4", leading to the lengthy discussion at https://github.com/go-chi/chi/issues/462.
Haha, to some, you may be scratching your head why I've spent > 1 year stalling to adopt "/vXX" convention in the import
path -- which isn't horrible in general -- but for chi, I'm unable to accept it as I strive for perfection in it's API design,
aesthetics and simplicity. It just doesn't feel good to me given chi's simple nature -- I do not foresee a "v5" or "v6",
and upgrading between versions in the future will also be just incremental.
I do understand versioning is a part of the API design as well, which is why the solution for a while has been to "do nothing",
as Go supports both old and new import paths with/out go.mod. However, now that Go module support has had time to iron out kinks and
is adopted everywhere, it's time for chi to get with the times. Luckily, I've discovered a path forward that will make me happy,
while also not breaking anyone's app who adopted a prior versioning from tags in v2/v3/v4. I've made an experimental release of
v1.5.0 with go.mod silently, and tested it with new and old projects, to ensure the developer experience is preserved, and it's
largely unnoticed. Fortunately, Go's toolchain will check the tags of a repo and consider the "latest" tag the one with go.mod.
However, you can still request a specific older tag such as v4.1.2, and everything will "just work". But new users can just
`go get github.com/go-chi/chi` or `go get github.com/go-chi/chi@latest` and they will get the latest version which contains
go.mod support, which is v1.5.0+. `chi` will not change very much over the years, just like it hasn't changed much from 4 years ago.
Therefore, we will stay on v1.x from here on, starting from v1.5.0. Any breaking changes will bump a "minor" release and
backwards-compatible improvements/fixes will bump a "tiny" release.
For existing projects who want to upgrade to the latest go.mod version, run: `go get -u github.com/go-chi/chi@v1.5.0`,
which will get you on the go.mod version line (as Go's mod cache may still remember v4.x). Brand new systems can run
`go get -u github.com/go-chi/chi` or `go get -u github.com/go-chi/chi@latest` to install chi, which will install v1.5.0+
built with go.mod support.
My apologies to the developers who will disagree with the decisions above, but, hope you'll try it and see it's a very
minor request which is backwards compatible and won't break your existing installations.
Cheers all, happy coding!

# Render [![GoDoc](http://godoc.org/github.com/unrolled/render?status.svg)](http://godoc.org/github.com/unrolled/render) [![Build Status](https://travis-ci.org/unrolled/render.svg)](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)
}
~~~
## Integration Examples
### [Echo](https://github.com/labstack/echo)
~~~ go
// main.go
package main
import (
"io"
"net/http"

)
type RenderWrapper struct { // We need to wrap the renderer because we need a different signature for echo.
rnd *render.Render
}
func (r *RenderWrapper) Render(w io.Writer, name string, data interface{},c echo.Context) error {
return r.rnd.HTML(w, 0, name, data) // The zero status code is overwritten by echo.
}
func main() {
r := &RenderWrapper{render.New()}
e := echo.New()
e.Renderer = r
e.GET("/", func(c echo.Context) error {
return c.Render(http.StatusOK, "TemplateName", "TemplateData")
