-- Put a dev server behind another port, proxying everything but one route.

local http = require("@neyuki/http")
local os = require("@neyuki/os")

-- Run a dev server first, e.g. `npm run dev` (Vite listens on 5173), then:
--   http://127.0.0.1:1234  is the dev server, byte for byte (HMR works too)
--   http://127.0.0.1:8080  answers /api/time itself and proxies the rest
local dev = http.forward(1234, 5173)
print("forwarding " .. dev.url .. " -> " .. dev.target)

http.serve(8080, function(request: Request): any
    local path = request:query()
    if (path == "/api/time") then
        return { headers = { ["content-type"] = "application/json" }, body = "{\"now\":" .. tostring(os.time()) .. "}\n" }
    end
    -- Anything else is the dev server's business; the answer is sent as is.
    -- (Vite's HMR socket cannot upgrade through here, so its client falls
    -- back to connecting to the dev server directly; the TCP forward above
    -- carries websockets fine.)
    return request:forward({host = "localhost", port = 3021})
