Emmett

Emmett is a full-stack Python web framework designed with simplicity in mind.

The aim of Emmett is to be clearly understandable, easy to be learned and to be used, so you can focus completely on your product's features:

from emmett import App, request, response
from emmett.orm import Database, Model, Field
from emmett.tools import service, requires

class Task(Model):
    name = Field.string()
    is_completed = Field.bool(default=False)

app = App(__name__)
app.config.db.uri = "postgres://user:password@localhost/foo"
db = Database(app)
db.define_models(Task)
app.pipeline = [db.pipe]

def is_authenticated():
    return request.headers.get("api-key") == "foobar"

def not_authorized():
    response.status = 401
    return {'error': 'not authorized'}

@app.route(methods='get')
@requires(is_authenticated, otherwise=not_authorized)
@service.json
async def todo():
    page = request.query_params.page or 1
    tasks = Task.where(
        lambda t: t.is_completed == False
    ).select(paginate=(page, 20))
    return {'tasks': tasks}

Status of the project

Emmett is production ready and is compatible with Python 3.8 and above versions.

Emmett follows a semantic versioning for its releases, with a {major}.{minor}.{patch} scheme for versions numbers, where:

Deprecations are kept in place for at least 3 minor versions, and the drop is always communicated in the upgrade guide.
