Pipeline-style response builder for API routes.

An alternative to Nex.json/2, Nex.html/2, etc. that uses Elixir pipe syntax to build responses incrementally.

Examples

def get(req) do
  Nex.Res.new()
  |> Nex.Res.json(%{users: list_users()})
end

def post(req) do
  Nex.Res.new()
  |> Nex.Res.status(201)
  |> Nex.Res.json(%{created: true})
end

def delete(req) do
  Nex.Res.new()
  |> Nex.Res.status(204)
  |> Nex.Res.send("")
end

def get(req) do
  Nex.Res.new()
  |> Nex.Res.redirect("/login")
end

def get(req) do
  Nex.Res.new()
  |> Nex.Res.set_header("x-request-id", "abc123")
  |> Nex.Res.status(200)
  |> Nex.Res.json(%{ok: true})
end
