)

func main() {
    app := neo.App()

    app.Get("/", func(ctx *neo.Ctx) (int, error) {

neo's Issues

Can we remove gorm from ctx?

I try to recommand neo to other people and they don't think gorm should be in ctx, which many people may never use it at all.

I know it's a break change, but that's make sense for a lightweight web frame. Even who need gorm, they may never use it in a route handle function. They must have some model, controller packages for that.

CORS support (or lack thereof)

I feel like neo has a potential of being a really nice Go library for building API's, but while trying to do so, I ran into another issue. CORS.

Currently, neo can only properly handle GET and simple POST requests from same origin.
Handling cors requires a bit of middleware code

    // CORS Middleware
    app.Use(func(ctx *neo.Ctx, next neo.Next) {
        if origin := ctx.Req.Header.Get("Origin"); origin != "" {
            ctx.Res.Header.Set("Access-Control-Allow-Origin", origin)
            ctx.Res.Header.Set("Access-Control-Allow-Credentials", "true")
            ctx.Res.Header.Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
            ctx.Res.Header.Set("Access-Control-Allow-Headers",
                "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization")
        }

        // back to neo
        next()
    })

, but the real pain is enabling POST, PUT, PATCH, DELETE... requests, since Neo doesn't expose router internals, one has to manually define OPTIONS region for every single endpoint.

    app.Options("/channels/:name", func(ctx *neo.Ctx) {
        ctx.Res.Raw([]byte(""), http.StatusOK)
    })
    app.Options("/channels", func(ctx *neo.Ctx) {
        ctx.Res.Raw([]byte(""), http.StatusOK)
    })

This is a lot of repetitive boilerplate, and is something the framework should be able to take care of in a more succint manner.

Note: My cors setup here isn't 100% correct and shound't be used as a reference.

Can not create skeleton using 'neo new'.

Use cases for event functionality

I have not seen a golang web framework that has events like this does.

I was looking for examples to see how and its use cases. Are there any ?

Also it seem to use a bus. Pretty smart.

Very curious and if you have more info / URLs please let me know

can you add sub region?

such as:
father := app.Region().Prefix("/login")
father.Use(fn Widdleware)
son := father.Region().Prefix("/son") (or son := father.Prefix("/son")) //whole is /login/son
son.Get("", func(ctx *neo.Ctx) (int, error) {
...
})

Would a single ctx.Error be better than ctx.Errors?

Hi, I see you add Errors to ctx, but I'm thinking what gin does may not a good idea.

Basically, when we get an error, we just want to return from route handler.
Collecting errors like gin seems doesn't make sense

Golang's team offered a best practice on their blog about handling errors: Errors are values

Their solution is: define a single error object in a top level struct ( which should be in ctx in our cases )

So we can do something like this:

ctx.Error := SomeFunc()
// we don't need to deal with error here, a middleware will handle it automatically
if ctx.Error != nil { return 0, nil}

But with ctx.Errors, I have to write more code:

err := SomeFunc()
if err != nil {
    ctx.Error(err)
    return 0, nil
}

If we handle it with ctx.Errors[0]:

ctx.Errors := make([]error, 1)
ctx.Errors[0] := SomeFunc()

In this way, ctx.HasErrors() will always be true even if ctx.Errors[0] is nil

Following golang team's strategy, with a single ctx.Error, we can even do something like this:

func SomeFunc(param1, param2, err) error {
    //check error first
    if err != nil {return}
    //do something
}

func SomeFunc2(param1, param2, err) error {
    if err != nil {return}
    //do something else
}


ctx.Error := SomeFunc(param1, param2, ctx.Error)
ctx.Error := SomeFunc2(param1, param2, ctx.Error)
ctx.Error := SomeFunc3(param1, param2, ctx.Error)
return 200, ctx.Text("done")
//then, middleware will handle ctx.Error, if there is one.

In this way, we don't need to check ctx.Error at all, since every function has checked that error at beginning, if there is an error, all those functions will just return.

I think golang team's solution is much better than gin's, a single ctx.Error may truely better than collecting all errors.

how to get wildcard param's value?

We need something like this:

    app.Get("/path/:name/*", func(c *neo.Ctx) (int, error) {
        others := c.Req.Params("*")
        //do something
    })

How can I get the value of wildcard? Thanks

p.s. neo is great, it's exactly what we need, its router is also much easy to use then gin and echo. Thanks for this great job

Remove "neo" topic from repo

Problem

The NEO blockchain team have created an official page for the neo topic on Github.

See here: https://github.com/topics/neo

This repo has added the neo topic however it isn't relevant as a topic, more just as a name.

Solution

Remove neo topic from repo.

Notes

None

Error running neo run command

I'm having problem running neo run at the moment. What might be at fault here?

Content-Type of JSON/XML responses

I think neo should automatically set Content-Type header for JSON/XML responses.

AssertNil will blow up

Doing this does blow up sometimes:

    app.Get("/downloads", func(ctx *neo.Ctx) {
        data, err := util.FolderScanner(util.RelativePath("tmp"), util.File)
        neo.AssertNil(err, http.StatusNoContent, []byte(err.Error()))
        ctx.Res.Json(data, http.StatusOK)
    })

If there is no error

neo.AssertNil(err, http.StatusNoContent, []byte(err.Error()))

Will cause nil pointer panic.

invalid character '-' in numeric literal

parsed := &myType{}
err := ctx.Req.JsonBody(parsed)
if err != nil {
return 200, ctx.Res.Text(err.Error())
}
Error：invalid character '-' in numeric literal

Neo cli to restart on static file changes

Is there anyway to just use neo cli to detect changes in all the files in the project? I love Neo and it's Express like architecture!

would we change the color of document site?

From dark theme into some bright theme, for example:

Sure dark theme is better for eyes, but bright theme make it looks more modern. I've already changed it in my fork, if it's ok to you, I'll create a pull request.

ctx.Req.JsonBody return EOF

client post json {'id':200,'name':"neo"} to route /api
want server return same json
test code :

package main
import (
    "github.com/ivpusic/neo"
_     "io/ioutil"
    "fmt"
)
func main() {
    app := neo.App()
    app.Get("/", func(ctx *neo.Ctx) (int, error) {
    	html:=`<html><head><script src="https://unpkg.com/axios/dist/axios.min.js"></script></head>
<body><script>
	axios.post('/api', {'id':200,'name':"neo"}).then(res => {  console.log(res.data); });
</script>
axios post 
</body><html>
	`
    	
        return 200, ctx.Res.Text(html)
    })

    app.Post("/api", func(ctx *neo.Ctx) (int, error) {
    	
   /*  body,err:=ioutil.ReadAll(ctx.Req.Body)
  	  fmt.Println(string(body))
      
	fmt.Println(ctx.Req.JsonBody(ctx.Req.Body))
	  
 	   if ( nil != err){
	   	    fmt.Println("err")
	      return 500,err
	   }
  */	
     fmt.Println(ctx.Req.Body)

    return 200,  ctx.Res.Json(ctx.Req.JsonBody(ctx.Req.Body))
    })

	    app.Start()
}

body,err:=ioutil.ReadAll(ctx.Req.Body)
read json correct
but ctx.Req.JsonBody(xxx) return EOF

Pls do not list all static file when visit /static

Maybe it need configuration to show it.

Is there a place to put all middlewares together?

So users of neo can get them more easily. maybe a list on a wiki page?

How to use Router group like iris's app.Party or gin's app.Group

How to wildcard "" and "/" for route?

Now need two func for route "/login" and "/login/"?
such as for "/"
app.Get("/", func(ctx *neo.Ctx) (int, error) {
...
})
i need another func for "":
app.Get("", func(ctx *neo.Ctx) (int, error) {
...
})

Why shell-script?

I want to try neo on Windows. But currently, neo/scripts is written in bash. So not possible.

https://github.com/ivpusic/neo/tree/master/cmd/neo/scripts

Can neo has Region params like gin‘s Group

Ex:

app:=neo.App()
g:=app.Region(“/admin”)
g.Use(xxx)
g.Get("/list",List)

the router should be "/admin/list",and use middle xxx

cannot create directory at 'aux'

When git wants to checkout it will show this error: fatal: cannot create directory at 'aux': Invalid argument. That's because aux is a reserved name on Windows.

neo cli run main.go won't work

Will get this panic:
panic: template: application-build-1454079793108505400.exe:1887: unexpected unrecognized character in action: U+FFFD '�' in command

There're many useless characters in log, which can not be displayed correctly on windows and get panic.

could we just remove them?

How neo use https?

app.Start() use http only,how can i use https?
