Kill Feed

Touches every layer | typed params, compression, server push, broadcast, wildcard routes, and middleware.

Server

local app       = RoExpress("App")
local broadcast = RoExpress("Broadcast")
local bridge    = RoExpress("Bridge")
local killFeed  = {}

app:Use("logger", function(Player, Payload)
    print(Player.Name, Payload.method, Payload.route)
end)

app:Post("stats/save", function(Player, Payload, req, res)
    local entry = { killer=req.data.killerName, victim=req.data.victimName, weapon=req.data.weapon, timestamp=os.time() }
    table.insert(killFeed, 1, entry)
    app:PushAll("killFeed.entry", entry)          -- reliable
    broadcast:EmitAll("killFeed.ping", { killer=req.data.killerName, victim=req.data.victimName }) -- unreliable
    bridge.Fire("kill.registered", entry)           -- internal bus
    res:Send({ success = true })
end)

app:Get("stats/:userId=number", function(Player, Payload, req, res)
    res:Send(stats[req.params.userId])  -- userId already a number
end)

app:Get("feed/all",    handler, { compress = true })
app:Get("feed/recent", handler)  -- ?limit=20
app:Get("feed/*/kills", handler) -- req.captures[1] = period

Client

listener:On("killFeed.entry", function(data) FeedUI:Add(data) end)
listener:On("killFeed.ping",  function(data) HUD:Flash(data) end)
network:Get("feed/all", nil, function(res) FeedUI:Load(res.data.entries) end)
