Faygo is a fast and concise Go Web framework that can be used to develop high-performance web app(especially API) with fewer codes. Just define a struct Handler, Faygo will automatically bind/verify the request parameters and generate the online API doc. Go to <User Manual>
v1.2.0
Go Version ≥ 1.8
- Way 1: download source
go get -u -v github.com/andeya/faygo- Way 2: deployment tools (Go to fay)
go get -u -v github.com/andeya/fay fay command [arguments]
The commands are:
new create, compile and run (monitor changes) a new faygo project
run compile and run (monitor changes) an any existing go project
fay new appname [apptpl]
appname specifies the path of the new faygo project
apptpl optionally, specifies the faygo project template type
fay run [appname]
appname optionally, specifies the path of the new project
- One
struct Handlercan get more things:
- Define Handler/Middleware
- Bind and verify request parameters
- Generate an online document for the Swagger 2.0 API
- Database ORM mapping
- Handler and Middleware are exactly the same, both implement the Handler interface (
funcorstruct), which together constitute the handler chain of the router. - Supports multiple network types:
| Network types | Configuration net_types |
|---|---|
| HTTP | http |
| HTTPS/HTTP2(TLS) | https |
| HTTPS/HTTP2(Let's Encrypt TLS) | letsencrypt |
| HTTPS/HTTP2(Let's Encrypt TLS on UNIX socket) | unix_letsencrypt |
| HTTP(UNIX socket) | unix_http |
| HTTPS/HTTP2(TLS on UNIX socket) | unix_https |
- Support single-service & single-listener, single-service & multi-listener, multi-service & multi-listener and so on. The config of multiple services is independent of each other
- The high-performance router based on
httproutersupports both chain and tree registration styles; supports flexible static file router (such as DirFS, RenderFS, MarkdownFS, etc.) - Support graceful shutdown and rebooting, provide fay tools which has new projects, hot compilation , meta programming function
- Use the most powerful
pongo2as the HTML rendering engine - Support near-LRU memory caching (mainly used for static file cache)
- Support cross-platform color log system, and has two output interface(console and file)
- Support session management (If you use a persistent storage engine, you must use gob.Register() to register the relevant custom type before starting the service)
- Support global gzip compression config
- Support XSRF security filtering
- Most features try to use simple ini configs to avoid unnecessary recompilation, and these profiles can be automatically assigned default values
- Provide
gorm,xorm,sqlx,directSQL,Websocket,ini,http clientand many other commonly used expansion packages

*/Handler and middleware are the same, both implemente Handler interface!
- function type
// Page handler doesn't contains API doc description
func Page() faygo.HandlerFunc {
return func(ctx *faygo.Context) error {
return ctx.String(200, "faygo")
}
}
// Page2 handler contains API doc description
var Page2 = faygo.WrapDoc(Page(), "test page2 notes", "test")- struct type
// Param binds and validates the request parameters by Tags
type Param struct {
Id int `param:"<in:path> <required> <desc:ID> <range: 0:10>"`
Title string `param:"<in:query>"`
}
// Serve implemente Handler interface
func (p *Param) Serve(ctx *faygo.Context) error {
return ctx.JSON(200,
faygo.Map{
"Struct Params": p,
"Additional Param": ctx.PathParam("additional"),
}, true)
}
// Doc implemente API Doc interface (optional)
func (p *Param) Doc() faygo.Doc {
return faygo.Doc{
// Add the API notes to the API doc
Note: "param desc",
// declare the response content format to the API doc
Return: faygo.JSONMsg{
Code: 1,
Info: "success",
},
// additional request parameter declarations to the API doc (optional)
Params: []faygo.ParamInfo{
{
Name: "additional",
In: "path",
Model: "a",
Desc: "defined by the `Doc()` method",
},
},
}
}The filter function must be HandleFunc type!
func Root2Index(ctx *faygo.Context) error {
// Direct access to `/index` is not allowed
if ctx.Path() == "/index" {
ctx.Stop()
return nil
}
if ctx.Path() == "/" {
ctx.ModifyPath("/index")
}
return nil
}- tree style
// New application object, params: name, version
var app1 = faygo.New("myapp1", "1.0")
// router
app1.Filter(Root2Index).
Route(
app1.NewNamedGET("test page", "/page", Page()),
app1.NewNamedGET("test page2", "/page2", Page2),
app1.NewGroup("home",
app1.NewNamedGET("test param", "/param", &Param{
// sets the default value in the API documentation for the request parameters (optional)
Id: 1,
Title: "test param",
}),
),
)- chain style
// New application object, params: name, version
var app2 = faygo.New("myapp2", "1.0")
// router
app2.Filter(Root2Index)
app2.NamedGET("test page", "/page", Page())

| param | in | only one | cookie | (position of param) request cookie info, support: *http.Cookie,http.Cookie,string,[]byte |
| param | name | no | (e.g.id) |

| param | required | no | request param is required | |
| param | desc | no | (e.g.id) |
request param description |
| param | len | no | (e.g.3:6) |
length range [a,b] of param's value |
| param | range | no | (e.g.0:10) |
numerical range [a,b] of param's value |
| param | nonzero | no | param`s value can not be zero | |
| param | maxmb | no | (e.g.32) |
when request Content-Type is multipart/form-data, the max memory for body.(multi-param, whichever is greater) |
| param | regexp | no | (e.g.^\\w+$) |
verify the value of the param with a regular expression(param value can not be null) |
| param | err | no | (e.g.incorrect password format) |
the custom error for binding or validating |
NOTES:
- the binding object must be a struct pointer
- in addition to
*multipart.FileHeader, the binding struct's field can not be a pointer - if the
paramtag is not exist, anonymous field will be parsed - when the param's position(
in) isformDataand the field's type is*multipart.FileHeader,multipart.FileHeader,[]*multipart.FileHeaderor[]multipart.FileHeader, the param receives file uploaded - if param's position(
in) iscookie, field's type must be*http.Cookieorhttp.Cookie - param tags
in(formData)andin(body)can not exist at the same time - there should not be more than one
in(body)param tag
