Teloce-Py

Build interactive Python apps with .vel components. No Node.js required.

Teloce-Py compiles a template, browser behavior, and scoped CSS from a single .vel file into plain browser assets. Your Python framework (Flask, FastAPI, Django, or Flaxon) keeps handling routes, APIs, databases, auth, and security.

Features

• Single-file components: template, script, and scoped style in one .vel file.
• Bring your own backend: works with Flask, FastAPI, Django, and Flaxon.
• No Node.js: production builds use MinifyJS, a native esbuild engine bundled in the wheel.
• Fast builds: tree shaking, mangling, code splitting, source maps, and hashed assets.

Getting Started

Install:

python -m pip install teloce-py Flask

Create static/js/App.vel:

<script>
export default {
  data() { return { count: 0 }; },
  methods: {
    increment() { this.count += 1; }
  }
};
</script>

<template>
  <button @click="increment">Clicked {{ count }} times</button>
</template>

Create app.py:

from pathlib import Path
from flask import Flask, render_template
from teloce.build import build_project

ROOT = Path(__file__).parent
build_project(ROOT, out_dir=ROOT / "dist", options={"dev": True})
app = Flask(__name__, static_folder="dist/static", static_url_path="/static")

@app.get("/")
def home():
    return render_template("app.html")

if __name__ == "__main__":
    app.run(debug=True)

Create templates/app.html:

<!doctype html>
<html>
  <body>
    <div id="app"></div>
    <script type="module">
      import { mount } from "{{ url_for('static', filename='js/App.js') }}";
      mount("#app");
    </script>
  </body>
</html>

Run it and open http://127.0.0.1:5000:

python app.py
