Server-sent events (SSE) is a technology where a browser receives automatic updates from a server via HTTP connection. The Server-Sent Events EventSource API is [standardized as part of HTML5[1] by the W3C](http://www.w3.org/TR/2009/WD-eventsource-20091029/).
|
||||
|
||||
- [Read this great SSE introduction by the HTML5Rocks guys](http://www.html5rocks.com/en/tutorials/eventsource/basics/)
|
||||
- [Browser support](http://caniuse.com/#feat=eventsource)
|
||||
|
||||
## Sample code
|
||||
|
||||
```go
|
||||
import "github.com/gin-contrib/sse"
|
||||
|
||||
func httpHandler(w http.ResponseWriter, req *http.Request) {
|
||||
// data can be a primitive like a string, an integer or a float
|
||||
sse.Encode(w, sse.Event{
|
||||
Event: "message",
|
||||
Data: "some data\nmore data",
|
||||
})
|
||||
|
||||
// also a complex type, like a map, a struct or a slice
|
||||
sse.Encode(w, sse.Event{
|
||||
Id: "124",
|
||||
Event: "message",
|
||||
Data: map[string]interface{}{
|
||||
"user": "manu",
|
||||
"date": time.Now().Unix(),
|
||||
"content": "hi!",
|
||||
},
|
||||
})
|
||||
}
|
||||
```
|
||||
```
|
||||
event: message
|
||||
data: some data\\nmore data
|
||||
|
||||
id: 124
|
||||
event: message
|
||||
data: {"content":"hi!","date":1431540810,"user":"manu"}
|
||||
|
||||
```
|
||||
|
||||
## Content-Type
|
||||
|
||||
```go
|
||||
fmt.Println(sse.ContentType)
|
||||
```
|
||||
```
|
||||
text/event-stream
|
||||
```
|
||||
|
||||
## Decoding support
|
||||
|
||||
There is a client-side implementation of SSE coming soon.

# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at teamgingonic@gmail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
|
||||
|
||||

Equal returns true iff protocol buffers a and b are equal.
|
||||
The arguments must both be pointers to protocol buffer structs.
|
||||
|
||||
Equality is defined in this way:
|
||||
- Two messages are equal iff they are the same type,
|
||||
corresponding fields are equal, unknown field sets
|
||||
are equal, and extensions sets are equal.
|
||||
- Two set scalar fields are equal iff their values are equal.
|
||||
If the fields are of a floating-point type, remember that
|
||||
NaN != x for all x, including NaN. If the message is defined
|
||||
in a proto3 .proto file, fields are not "set"; specifically,
|
||||
zero length proto3 "bytes" fields are equal (nil == {}).
|
||||
- Two repeated fields are equal iff their lengths are the same,
|
||||
and their corresponding elements are equal. Note a "bytes" field,
|
||||
although represented by []byte, is not a repeated field and the
|
||||
rule for the scalar fields described above applies.
|
||||
- Two unset fields are equal.
|
||||
- Two unknown field sets are equal if their current
|
||||
encoded state is equal.
|
||||
- Two extension sets are equal iff they have corresponding
|
||||
elements that are pairwise equal.
|
||||
- Two map fields are equal iff their lengths are the same,
|
||||
and they contain the same set of elements. Zero-length map
|
||||
fields are equal.
|
||||
- Every other combination of things are not equal.
|
||||

||||
The return value is undefined if a and b are not protocol buffers.

Package proto converts data structures to and from the wire format of
|
||||
protocol buffers. It works in concert with the Go source code generated
|
||||
for .proto files by the protocol compiler.
|
||||
|
||||
A summary of the properties of the protocol buffer interface
|
||||
for a protocol buffer variable v:
|
||||
|
||||
- Names are turned from camel_case to CamelCase for export.
|
||||
- There are no methods on v to set fields; just treat
|
||||
them as structure fields.
|
||||
- There are getters that return a field's value if set,
|
||||
and return the field's default value if unset.
|
||||
The getters work even if the receiver is a nil message.
|
||||
- The zero value for a struct is its correct initialization state.
|
||||
All desired fields must be set before marshaling.
|
||||
- A Reset() method will restore a protobuf struct to its zero state.
|
||||
- Non-repeated fields are pointers to the values; nil means unset.
|
||||
That is, optional or required field int32 f becomes F *int32.
|
||||
- Repeated fields are slices.
|
||||
- Helper functions are available to aid the setting of fields.
|
||||
msg.Foo = proto.String("hello") // set field
|
||||
- Constants are defined to hold the default values of all fields that
|
||||
have them. They have the form Default_StructName_FieldName.
|
||||
Because the getter methods handle defaulted values,
|
||||
direct use of these constants should be rare.
|
||||
- Enums are given type names and maps from names to values.
|
||||
Enum values are prefixed by the enclosing message's name, or by the
|
||||
enum's type name if it is a top-level enum. Enum types have a String
|
||||
method, and a Enum method to assist in message construction.
|
||||
- Nested messages, groups and enums have type names prefixed with the name of
|
||||
the surrounding message type.
|
||||
- Extensions are given descriptor names that start with E_,
|
||||
followed by an underscore-delimited list of the nested messages
|
||||
that contain it (if any) followed by the CamelCased name of the
|
||||
extension field itself. HasExtension, ClearExtension, GetExtension
|
||||
and SetExtension are functions for manipulating extensions.
|
||||
- Oneof field sets are given a single field in their message,
|
||||
with distinguished wrapper types for each possible field value.
|
||||
- Marshal and Unmarshal are functions to encode and decode the wire format.
|
||||
|
||||
When the .proto file specifies `syntax="proto3"`, there are some differences:
|
||||
|
||||
- Non-repeated fields of non-message type are values instead of pointers.
|
||||
- Enum types do not get an Enum method.
|
||||
|
||||
The simplest way to describe this is to see an example.
|
||||
Given file test.proto, containing
|
||||
|
||||
package example;
|
||||
|
||||
enum FOO { X = 17; }
|
||||
|
||||
message Test {
|
||||
required string label = 1;
|
||||
optional int32 type = 2 [default=77];
|
||||
repeated int64 reps = 3;
|
||||
optional group OptionalGroup = 4 {
|
||||
required string RequiredField = 5;
|
||||
}
|
||||
oneof union {
|
||||
int32 number = 6;
|
||||
string name = 7;
|
||||
}
|
||||
}
