Glutinum.Express

Glutinum.Express

Fable bindings for express, generated by Glutinum

Generated by Glutinum from @types/express.

The bindings live in the Glutinum.Express module. Express.Exports.express () creates the application, Exports.json, Exports.urlencoded and Exports.Router are the values of the express namespace, and its types are Express.Request, Express.Response and Express.RequestHandler.

open Glutinum
open Glutinum.Express

let app = Exports.express ()

// The JSON body parser, a middleware of connect
app.``use`` (ExpressAdapter.Middleware(Exports.json None)) |> ignore

// A handler takes the request and the response, `ExpressAdapter.RequestHandler` also accepts `next`
app.get ("/users/:id", ExpressAdapter.RequestHandler(fun request response ->
    let id = unbox<string> request.``params``.["id"]
    response.json {| id = id; name = "Ada" |} |> ignore))
|> ignore

app.post ("/users", ExpressAdapter.RequestHandler(fun request response ->
    response.status(201).json {| name = request.body?name |} |> ignore))
|> ignore

app.listen 3000 |> ignore

ExpressAdapter is hand-written in Glutinum.Express.Extensions.fs, shipped with the package. The route methods (get, post, all, use...) return the application, so a call ends with |> ignore. The tests/App.fs file of this folder is a complete example.

Install the npm package next to the NuGet package, or run femto to do it.
