+# production-one-port
+
+This docker deployment runs Reflex in prod mode, exposing a single HTTP port:
+  * `8080` (`$PORT`) - Caddy server hosting the frontend statically and proxying requests to the backend.
+
+The deployment also runs a local Redis server to store state for each user.
+
+Conceptually it is similar to the `simple-one-port` example except it:
+  * has layer caching for python, reflex, and node dependencies
+  * uses multi-stage build to reduce the size of the final image
+
+Using this method may be preferable for deploying in memory constrained
+environments, because it serves a static frontend export, rather than running
+the NextJS server via node.
+
+## Build
+
+```console
+docker build -t reflex-production-one-port .
+```
+
+## Run
+
+```console
+docker run -p 8080:8080 reflex-production-one-port
+```
+
+Note that this container has _no persistence_ and will lose all data when
+stopped. You can use bind mounts or named volumes to persist the database and
+uploaded_files directories as needed.
+
+## Usage
+
+This container should be used with an existing load balancer or reverse proxy to
+terminate TLS.
+
+It is also useful for deploying to simple app platforms, such as Render or Heroku.

+# Reflex
+
+Reflex là một thư viện để xây dựng ứng dụng web toàn bộ bằng Python thuần.
+
+Các tính năng chính:
+* **Python thuần tuý** - Viết toàn bộ ứng dụng cả backend và frontend hoàn toàn bằng Python, không cần học JavaScript.
+* **Full Flexibility** - Reflex dễ dàng để bắt đầu, nhưng cũng có thể mở rộng lên các ứng dụng phức tạp.
+* **Deploy Instantly** - Sau khi xây dựng ứng dụng, bạn có thể triển khai bằng [một dòng lệnh](https://reflex.dev/docs/hosting/deploy-quick-start/) hoặc triển khai trên server của riêng bạn.
+
+Đọc [bài viết về kiến trúc hệ thống](https://reflex.dev/blog/2024-03-21-reflex-architecture/#the-reflex-architecture) để hiểu rõ các hoạt động của Reflex.
+
+## ⚙️ Cài đặt
+
+Mở cửa sổ lệnh và chạy (Yêu cầu Python phiên bản 3.9+):
+
+```bash
+pip install reflex
+```
+
+## 🥳 Tạo ứng dụng đầu tiên
+
+Cài đặt `reflex` cũng như cài đặt công cụ dòng lệnh `reflex`.
+
+Kiểm tra việc cài đặt đã thành công hay chưa bằng cách tạo mới một ứng dụng. (Thay `my_app_name` bằng tên ứng dụng của bạn):
+
+```bash
+mkdir my_app_name
+cd my_app_name
+reflex init
+```
+
+Lệnh này tạo ra một ứng dụng mẫu trong một thư mục mới. 
+
+Bạn có thể chạy ứng dụng ở chế độ phát triển.
+
+```bash
+reflex run
+```
+
+Bạn có thể xem ứng dụng của bạn ở địa chỉ http://localhost:3000.
+
+Bạn có thể thay đổi mã nguồn ở `my_app_name/my_app_name.py`. Reflex nhanh chóng làm mới và bạn có thể thấy thay đổi trên ứng dụng của bạn ngay lập tức khi bạn lưu file.
+
+
+## 🫧 Ứng dụng ví dụ
+
+Bắt đầu với ví dụ: tạo một ứng dụng tạo ảnh bằng [DALL·E](https://platform.openai.com/docs/guides/images/image-generation?context=node). Để cho đơn giản, chúng  ta sẽ sử dụng [OpenAI API](https://platform.openai.com/docs/api-reference/authentication), nhưng bạn có thể sử dụng model của chính bạn được triển khai trên local.

+</div>
+
+&nbsp;
+
+Đây là toàn bộ đoạn mã để xây dựng ứng dụng trên. Nó được viết hoàn toàn trong một file Python!
+
+
+  
+```python

+
+
+### **Reflex UI**
+
+Bắt đầu với giao diện chính.
+
+```python
+def index():
+    return rx.center(
+        ...
+    )
+```
+
+Hàm `index` định nghĩa phần giao diện chính của ứng dụng.
+
+Chúng tôi sử dụng các component (thành phần) khác nhau như `center`, `vstack`, `input` và `button` để xây dựng giao diện phía trước.
+Các component có thể được lồng vào nhau để tạo ra các bố cục phức tạp. Và bạn cũng có thể sử dụng từ khoá `args` để tận dụng đầy đủ sức mạnh của CSS.
+
+Reflex có đến hơn [60 component được xây dựng sẵn](https://reflex.dev/docs/library) để giúp bạn bắt đầu. Chúng ta có thể tạo ra một component mới khá dễ dàng, thao khảo: [xây dựng component của riêng bạn](https://reflex.dev/docs/wrapping-react/overview/).
+
+### **State**
+
+Reflex biểu diễn giao diện bằng các hàm của state (trạng thái).
+
+```python
+class State(rx.State):
+    """The app state."""
+    prompt = ""
+    image_url = ""
+    processing = False
+    complete = False
+
+```
+
+Một state định nghĩa các biến (được gọi là vars) có thể thay đổi trong một ứng dụng và cho phép các hàm có thể thay đổi chúng.
+
+Tại đây state được cấu thành từ một `prompt` và `image_url`.
+Có cũng những biến boolean `processing` và `complete`
+để chỉ ra khi nào tắt nút (trong quá trình tạo hình ảnh)
+và khi nào hiển thị hình ảnh kết quả.
+
+### **Event Handlers**
+
+```python
+def get_image(self):
+    """Get the image from the prompt."""
+    if self.prompt == "":
+        return rx.window_alert("Prompt Empty")
+
+    self.processing, self.complete = True, False
+    yield
+    response = openai_client.images.generate(
+        prompt=self.prompt, n=1, size="1024x1024"
+    )
+    self.image_url = response.data[0].url
+    self.processing, self.complete = False, True
+```
+
+Với các state, chúng ta định nghĩa các hàm có thể thay đổi state vars được gọi là event handlers. Event handler là cách chúng ta có thể thay đổi state trong Reflex. Chúng có thể là phản hồi khi người dùng thao tác, chằng hạn khi nhấn vào nút hoặc khi đang nhập trong text box. Các hành động này được gọi là event.
+
+Ứng dụng DALL·E. của chúng ta có một event handler, `get_image` để lấy hình ảnh từ OpenAI API. Sử dụng từ khoá `yield` in ở giữa event handler để cập nhật giao diện. Hoặc giao diện có thể cập nhật ở cuối event handler.
+
+### **Routing**
+
+Cuối cùng, chúng ta định nghĩa một ứng dụng.
+
+```python
+app = rx.App()
+```
+
+Chúng ta thêm một trang ở đầu ứng dụng bằng index component. Chúng ta cũng thêm tiêu đề của ứng dụng để hiển thị lên trình duyệt.
+
+
+```python
+app.add_page(index, title="DALL-E")
+```
+
+Bạn có thể tạo một ứng dụng nhiều trang bằng cách thêm trang.

+## ✅ Status
+
+Reflex phát hành vào tháng 12/2022 với tên là Pynecone.
+
+Đến tháng 02/2024, chúng tôi tạo ra dịch vụ dưới phiên bản alpha! Trong thời gian này mọi người có thể triển khai ứng dụng hoàn toàn miễn phí. Xem [roadmap](https://github.com/reflex-dev/reflex/issues/2727) để biết thêm chi tiết.
+
+Reflex ra phiên bản mới với các tính năng mới hàng tuần! Hãy :star: star và :eyes: watch repo này để thấy các cập nhật mới nhất.
