Here is the complete code to create this. This is all done in one Python file! - Live App: https://dalle.pynecone.app ```python import pynecone as pc import openai openai.api_key = "YOUR_API_KEY" class State(pc.State): """The app state.""" prompt = "" image_url = "" image_processing = False image_made = False def process_image(self): """Set the image processing flag to true and indicate image is not made yet.""" self.image_processing = True self.image_made = False def get_image(self): """Get the image from the prompt.""" response = openai.Image.create(prompt=self.prompt, n=1, size="1024x1024") self.image_url = response["data"][0]["url"] self.image_processing = False self.image_made = True def index(): return pc.center( pc.vstack( pc.heading("DALL-E", font_size="1.5em"), pc.input(placeholder="Enter a prompt..", on_blur=State.set_prompt), pc.button( "Generate Image", on_click=[State.process_image, State.get_image], width="100%", ), pc.divider(), pc.cond( State.image_processing, pc.circular_progress(is_indeterminate=True), pc.cond( State.image_made, pc.image( src=State.image_url, height="25em", width="25em", ) ) ), bg="white", padding="2em", shadow="lg", border_radius="lg", ), width="100%", height="100vh", bg="radial-gradient(circle at 22% 11%,rgba(62, 180, 137,.20),hsla(0,0%,100%,0) 19%)", ) # Add state and page to the app. app = pc.App(state=State) app.add_page(index, title="Pynecone:DALL-E") app.compile() ``` Let's break this down. ### **UI In Pynecone** Lets start by talking about the UI this Pynecone App. ```python def index(): return pc.center( ... ) ``` This index function defines the frontend of the app. We use different components such as `center`, `vstack`, `input`, and `button` to build the front end. Components can be nested to create complex layouts and styled using CSS's full power. Just pass them in as keyword args. Pynecone comes with [50+ built-in components](https://pynecone.io/docs/library) to help you get started. We are actively adding more components, plus it's easy to create your own components. ### **State** ``` python class State(pc.State): """The app state.""" prompt = "" image_url = "" image_processing = False image_made = False ``` The state defines all the variables (called vars) in an app that can change and the functions that change them. Here the state is comprised of a `prompt` and `image_url`. There are also the booleans `image_processing` and `image_made` to indicate when to show the circular progress and image. ### **Event Handlers** ```python def process_image(self): """Set the image processing flag to true and indicate image is not made yet.""" self.image_processing = True self.image_made = False def get_image(self): """Get the image from the prompt.""" response = openai.Image.create(prompt=self.prompt, n=1, size="1024x1024") self.image_url = response["data"][0]["url"] self.image_processing = False self.image_made = True ``` Within the state, we define functions called event handlers that change the state vars. Event handlers are the way that we can modify the state in Pynecone. They can be called in response to user actions, such as clicking a button or typing in a text box. These actions are called events. Our dalle app has two event handlers, `process_image` to indicate that the image is being generated and `get_image`, which calls the OpenAI API. ### **Routing** Finally we define our app and tell it what state to use. ```python app = pc.App(state=State) ``` We add a route from the root of the app to the index component. We also add a title that will show up in the page preview/ browser tab. ```python app.add_page(index, title="Pynecone:DALL-E") app.compile() ``` You can create a multi-page app by adding more routes. ## Status As of December 2022, Pynecone has just been released publicly and is in the **Alpha Stage**. - :large_orange_diamond: **Public Alpha**: Anyone can install and use Pynecone. There may be issues, but we are working to resolve them activly. - **Public Beta**: Stable enough for non-enterprise use-cases. - **Public Hosting Beta**: **Optionally** Deploy and Host your own apps on Pynecone! - **Public**: Pynecone is production ready. Pynecone has new releases and features coming every week! Make sure to: :star: star and :eyes: watch this repository to stay up to date. ## Contributing We welcome contributions of any size!
