# Listen to Pull Requests and start ephemeral Spaces on new PRs! 🚀

**Gradio Space CI** is a tool to create ephemeral Spaces for each PR opened on your Space repo.
The goal is to improve developer experience by making the review process as lean as possible.

#### ⚠️ Disclaimer: **Gradio Space CI** works only on public Spaces.

## ⚡ Quick start (4 steps)

1. Update your requirements.

```py
# requirements.txt
gradio-space-ci @ git+https://huggingface.co/spaces/Wauplin/gradio-space-ci@0.2.2
```

2. Set `HF_TOKEN` as a Space secret.
3. Configure CI in your `README.md`.

```py
# README.md
title: ...
emoji: ...
sdk: gradio
space_ci:
   trusted_authors:
      - clefourrier
   secrets:
      - HF_TOKEN
   hardware: cpu-basic
   storage: null
```

4. Enable CI in `app.py`.

```py
# app.py
from gradio_space_ci import enable_space_ci

enable_space_ci()
```

And that's it! For more details, check out the [integration](#integration) section.

## ✨ Key features

1. **Listen to Pull Requests**.
2. **Launch ephemeral Spaces** on new PRs.
   1. When a commit is pushed to a PR, the ephemeral Space gets synchronized.
   2. When the PR is closed, the ephemeral Space is deleted.
3. Configure ephemeral Spaces automatically
   1. All **variables** are copied from the main Space.
   2. **Secrets** are copied from the main Space, based on CI configuration.
   3. **Hardware** and **storage** are set, based on CI configuration.
4. Only **trusted authors** are able to access secrets
   1. By default, repo owners are trusted authors
   2. More authors can be added in CI configuration
   3. untrusted authors can start ephemeral Space but without secrets or custom hardware

## ⚙️ Integration

Integrate *Gradio Space CI* in just a few steps:

### 1. Update your `requirements.txt`

If you don't have a `requirements.txt` file yet, create one in your Space repo.
Add the following line to it:

```bash
# requirements.txt
gradio-space-ci @ git+https://huggingface.co/spaces/Wauplin/gradio-space-ci@0.2.2
```

### 2. Add a user token as `HF_TOKEN` secret

1. Go to your [user settings page](https://huggingface.co/settings/tokens).
2. Create a new token with **write** permissions.
3. Go to your Space settings page.
4. Add `HF_TOKEN` as a Space secret with your newly created token.

(optional) You can also define a `SPACE_CI_SECRET` secret value that will be used to authenticate webhook calls. If you don't define one, a random secret value will be generated for you.

### 3. Configure CI in `README.md`

Edit the Space metadata in your `README.md` file:

```yaml
title: ...
sdk: gradio
sdk_version: ...
app_file: ...
space_ci:
   trusted_authors:
      - Wauplin
      # ^ Only PRs from trusted authors are deployed in an ephemeral Space.
      # Space owners are automatically trusted.
      # It is possible to manually trust other authors by adding them as a list.
   private: auto
      # ^ Can be 'true', 'false' or 'auto'. If 'auto', the ephemeral Spaces will have same
      # visibility as the main Space.
   variables: auto
      # ^ By default ('auto'), all variables from the main Space are copied to the ephemeral Space.
      # Otherwise, you can define a key-value mapping with variables to set.
      # Variables are injected as environment variable in the ephemeral Space and are public for anyone landing on the Space.
   secrets:
      - HF_TOKEN
      # ^ A list of secrets that must be copied from the main Space to the ephemeral Spaces.
      # Secrets are injected as environment variable in the ephemeral Space.
      # Be careful with the 'trusted_authors' list when setting secrets. 
   hardware: cpu-basic
      # ^ Defines which hardware to assign to the ephemeral Space.
      # Can be set to 'auto' to assign the same hardware as the main Space.
      # Defaults to 'cpu-basic' (free).
   storage: null
      # ^ Defines which storage to assign to the ephemeral Space.
      # Can be set to 'auto' to assign the same storage as the main Space.
      # Defaults to no storage (free).
```

### 4. Enable CI in `app.py`

Call `enable_space_ci` in your `app.py` file:

```py
# app.py
import gradio as gr
from gradio_space_ci import enable_space_ci

enable_space_ci()

# ANY gradio app
with gr.Blocks() as demo:
    ...
demo.launch()
```

And you're done! Ephemeral Spaces will be launched for each and every PR on your repo.
