Single page app with public asset directory about httprouter

[bhenderson]

You could just combine the two routes. (See http.StripPrefix)

prefix := "/public/"
fileServer := http.FileServer("./public")
r.GET("/*filepath", func(c *gin.Context) {
    if p := strings.TrimPrefix(c.Req.URL.Path, prefix); len(p) < len(c.Req.URL.Path) {
        c.Req.URL.Path = p
        fileServer.ServeHTTP(c.Writer, c.Req)
        return
    }
    //...
})

Thanks @bhenderson, This works well until I have to load css or js assets from another prefix. Say the page is now at web/somedir/ the index page loads but now the assets do not unless I identify each and every prefix. Ultimately I'd be able to have the routes and static functions operate independently. Being used to other languages where the order of the routes matter, httprouter is a better system but adjusting to how to set up the routes without regex for a single page app is challenging.

You can solve this problem in the view, one way to do it is pass your template the prefix you want for the particular page. This way you can use one template and always know where the assets are relative to it.

@hoffoo That's a great idea. I'll give it a shot.

Basically, I'm trying to duplicate the following node.js snippet using httprouter:

app.use(express.static(__dirname + '/public'));
app.get('*', function(req, res) {
    res.render('index');
});

@mr170 maybe you should set the NotFound handler to serve your index, and configure routes for your static files.

Using NotFound is an option, but not a good one IMO. Currently there is no nice way to implement a routing structure like this with HttpRouter.

But I see that there is a demand for something "catch-rest" like (see also #7 and #4), . I have plans to add an option for this.

@julienschmidt I browsed through the commits after this date, but didn't seem to find an option for this. Would you please provide some feedback ?
Perhaps #4's solution, adding RedirectTrailingSlash and RedirectFixedPath off, is the way to go ?
