Generates the project with all needed files.

Project-Name
├── frontend - HTML, CSS, Pype frontend library.
│ └── assets - Any asset file.
└── app.py

Project build

Generates an .exe executable file from the given project. The project should follow the generated structure.

Expose

Description:
Exposes a function to the frontend side to be called

Example:

app.expose(functionFromPython)

Call

Description:
Calls an exposed function from the frontend

Example:

onclick="call('functionFromPython')"

State Management

Push

Applies and finalizes state changes by triggering observers and hooks. Updates are batched for efficiency, ensuring cleaner and more controlled state management. It offers on-demand state updates, reducing unnecessary processing.

Python:

app.state["numbers"].append(value)
        
app.push(["numbers","some other key","...another"]) #finalizes state change

JavaScript:

onclick="state['count']++; push(['count'])"

Pull

Gets a state values deep copied value, for other usage then just immidietly setting state.

Python:

app.pull("count")

JavaScript:

onclick="alert(pull('count'))"

---

Binds

Description:
Binds a state to an element via its key attribute and specifies which attribute should be updated upon a state change.

Example:

app.bind('state-key', 'element-key', HTMLAttributes.INNERHTML)

---

Hooks

Description:
Attaches a function to a specific state change. When the state updates, the hooked function is called.

Example:

app.hook('state-key', hooked_function)

---

Prefabs

Creation

Description:
Users can create prefabs that can be instantiated or destroyed by the app. Attributes are passed as Python dictionaries.

Example (HTML):

<prefab id="prefab-name">
    <div class="number" style="color: $attribute-name-2; border-color: $attribute-name-2;">$attribute-name</div>
</prefab>

---

Instantiate

Description:
Instantiates a prefab with a unique key under a specified parent element, passing attributes to customize its content.

Example:

app.instantiate("prefab-name", f"key-prefix-{count}", "prefab-parent-id", {"attribute1": 'something', "attribute2": 0})

---

Destroy

Description:
Destroys a prefab with the specified ID and key. During destruction, the prefab enters its destruction phase and receives the .destroyed class for exit animations.

Example:

app.destroy("prefab-name", f"key-prefix-{prevCount}")

Observer

Description:
Observes a state array that contains attributes for prefabs, upon its change automatically instantiates or destroys prefabs.

Example:

app.observe('state-key','prefab-id','key-prefix','prefab-parent-id')

Load Page

Description:
Loads a given page exposed to the run function. .unloaded class for the current page for exit animations.

Example:

app.run([updatingFunc],["index.html","new-page.html"]) #Expose pages to app

app.load_page(1)

Custom Window Handle

Description:
All pages has a .window-handle div at top. This area is customizable too for making it fit with your app.
