🚀 New

• Ctx: Context method for query paramters with numbers (#2306) https://docs.gofiber.io/api/ctx#queryint

// GET http://example.com/?id=5555 app.Get("/", func(c *fiber.Ctx) error { c.QueryInt("id", 1) // 5555 // ... })

• Middleware/earlydata: Add earlydata middleware (v2 backport) (#2314) https://docs.gofiber.io/api/middleware/earlydata

adds support for TLS 1.3's early data ("0-RTT") feature

app.Use(earlydata.New())

• Middleware/idempotency: Add idempotency middleware (v2 backport) (#2288) https://docs.gofiber.io/api/middleware/idempotency

allows for fault-tolerant APIs where duplicate requests — for example due to networking issues on the client-side — do not erroneously cause the same action performed multiple times on the server-side.

app.Use(idempotency.New(idempotency.Config{ Lifetime: 42 * time.Minute, // ... }))

• Middleware/proxy: Add forward from domain (#2323) https://docs.gofiber.io/api/middleware/proxy

// If you want to forward with a specific domain. You have to use proxy.DomainForward. app.Get("/payments", proxy.DomainForward("docs.gofiber.io", "http://localhost:8000")) // Or this way if the balancer is using https and the destination server is only using http. app.Use(proxy.BalancerForward([]string{ "http://localhost:3001", "http://localhost:3002", "http://localhost:3003", }))
