CORS in x.vweb

[MedLabs]

Describe the feature

Enabling CORS in a REST API is very important, there is an example created by @spytheman in vweb/cors app.add_header("Access-Control-Allow-Origin", "*")
but in x.vweb it doesn't work, and I think it could be a better and faster way to configure CORS, instead of adding a preflight function on @['/:path...'; options]

Why not add a Context function that takes the CORS config and could be added to before_request if we want the same config to all endpoints, or to be added to some endpoints as an argument...

Use Case

Usually in other frameworks, I import cors library and set the cors options in a variable then app.use(corsOptions)

Proposed Solution

a Context function that takes Origin, Methods etc as arguments...
ctx.set_cors("*", "GET, POST, PUT, DELETE")

hi.
i looked inside x.vweb module and find out that there is a complete and powerfull cors middleware for handling cors that you can use.

Example:

app.use(vweb.cors[Context](vweb.CorsOptions{
    origin: '*'
    allowed_methods: [.get, .head, .patch, .put, .post, .delete]
}))
