Coloco

A kit for creating full-stack apps with co-located code, built on FastAPI and Svelte. Bundle your front-end and back-end code and easily tie them together with codegen.

Example:

hello/api.py

from coloco import api

@api
def test(name: str):
    return f"Hello {name}!"

hello/index.svelte

<script lang="ts">
  import { test } from "./api";
</script>

{#await test({ name: "Coloco" })}
	Loading...
{:then result}
	The server says {result}
{/await}

Serves the page myapp.com/hello, which calls myapp.com/hello/test?name=Coloco and prints the message Hello Coloco!

Getting Started

pip install coloco
coloco createapp myapp
From myapp - coloco dev

Running in Production

coloco build
Artifacts will be saved to dist
From dist, run coloco serve

Opinions

This framework is opinionated and combines the following excellent tools:

FastAPI
Svelte
openapi-ts (codegen)
svelte5-router (file-based routing)
tortoise-orm (optional)

TBD Required features for launch

Config with secrets encryption
Package/share modules with git
Docs

Features in development

CRUD
Caching
User module
Dev tools module
Admin panel module

Dreams

Move node_modules into +node

Other TODO

Swap to copier for template creation
Textual CLI app / installer / dev tools?
Resolve duplicate types in openapi spec (due to model serializers)
