Release Notes¶

3.5.0¶

Added¶

Allow passing HTTP/WebSocket handlers directly to routes. They are automatically wrapped in Gateways-
Allow passing HTTP/WebSocket handlers directly to routes as alternative to defining a Gateway/WebsocketGateway.

Changed¶

Esmerald is now under the License BSD-3. This aims to protect the maintainers and contributors and the license will be now the final.
Pluggables can now receive plain Extensions and Extension classes.
Rename of Pluggables to Extensions:
- Breaking: The pluggables attribute and parameter are now renamed to extensions. The old name is still available but deprecated.
- Breaking: The add_pluggable method is now renamed to add_extension. The old name is still available but deprecated.
- The documentation will refer now to extensions with Pluggable as a setup wrapper.

Fixed¶

Directive runserver now allows the use of ASGI middlewares.
Remove the dependency of an app being an esmerald instance for runserver.
Check the environment variables instead of settings variable for esmerald settings in the runserver.

3.4.4¶

Added¶

Support for Taskfile when generating a project via directive.
Add taskfile for development mode.

Changed¶

Internal JSONResponse is now natively supporting ORJSON.

3.4.3¶

Changed¶

PydanticEncoder now tries mode json first as default.
Stop ignoring warnings in the tests.
Stop shadowing the BaseDirective help from Lilya.
Asyncz settings for empty tasks.
Update the docs for the templates.

3.4.2¶

Changed¶

OpenAPI for inheritance models using pydantic or any type of encoders.
Stop supporting Python 3.8.
Changed internal schema location in the helpers.

3.4.1¶

Changed¶

OpenAPI now if no description is provided from the handlers, it will read directly from the docstrings.
Internal code cleaning and organisation.

Fixed¶

OpenAPI query parameters were not rendering properly for optional dict or list types. This was due to the internal evaluation of the None field which is now skipping for OpenAPI purposes.

Example¶

Now it is possible to do something like this:

from typing import Dict, List, Union, Optional

from esmerald import Gateway, JSONResponse, Query, get


@get("/item")
async def check_item(q: Union[List[str], None]) -> JSONResponse:
    return JSONResponse({"value": q})


@get("/another-item")
async def check_item(q: Optional[Dict[str, str]]) -> JSONResponse:
    return JSONResponse({"value": q})

3.4.0¶

Added¶

New ways of providing the request data allowing to pass a more complex body using also the encoders. The complex body is explained and how to achieve this result.

Warning

This is an additional functionality to the existing one and it does not represent any replacement. Be sure you read the documentation and if you understand it.

Example¶

As per some examples of the documentation:

from pydantic import BaseModel, EmailStr

from esmerald import Esmerald, Gateway, post


class User(BaseModel):
    name: str
    email: EmailStr


class Address(BaseModel):
    street_name: str
    post_code: str


@post("/create")
async def create_user(user: User, address: Address) -> None:
    """
    Creates a user in the system and does not return anything.
    Default status_code: 201
    """


app = Esmerald(routes=[Gateway(handler=create_user)])

You can expect to send a payload like this:

{
    "user": {
        "name": "John",
        "email": "john.doe@example.com",
    },
    "address": {
        "street_name": "123 Queens Park",
        "post_code": "90241"
    }
}

More details can and must be read in the request data section.

Changed¶

Overriding the status_code in any response is now possible directly by specifying the intended response and ignoring the default from the handler.

Example¶

@get()
def create(name: Union[str, None]) -> Response:
    if name is None:
        return Response("Ok")
    if name == "something":
        return Response("Ok", status_code=status.HTTP_401_UNAUTHORIZED)
    if name == "something-else":
        return Response("Ok", status_code=status.HTTP_300_MULTIPLE_CHOICES)

If none of the conditions are met, then it will always default to the status_code of the handler which in the get case, its 200.

Fixed¶

Internal parsing of the encoders for OpenAPI representation and removed unused code (deprecated).

3.3.7¶

Added¶

New application generator using --context allowing to generate application scaffolds containing more complex structures.

Changed¶

jinja2 templating is now 100% delegated to its base, Lilya.
Added examples in the documentation for windows users.

Fixed¶

Lookup for summary in the handler for OpenAPI.

3.3.6¶

Added¶

allow_private_networks property to CORSMiddleware.

Changed¶

Gateway now allows to pass also an optional operation_id as parameter for OpenAPI documentation allowing multiple gateways to use the same handler and being recognised automatically by OpenAPI documentation.
OpenAPI documentation when multiple gateways use the same handler and no operation_id is declared, automatically tries to generate a unique operation_id for it.
Internal code organisation for class based View to generate the routes in one place and reducing code duplication.
Updated internal testing requirements for Edgy and Saffier and Lilya.

3.3.5¶

This was missed from the release 3.3.4 and it was supposed to be included.

Added¶

Native types for Esmerald transformer models/
Hashing list internally for the signature allowing lists to be declared for OpenAPI representation.

Changed¶

Query parameters when declared as list, List, dict and Dict automatically parses the values to the declared type.
OpenAPI understands the native types, objects and lists (arrays).

3.3.4¶

Added¶

Missing documentation for Query Parameters and Path Parameters.

Changed¶

Documentation for Extra, Advanced && Useful is now renamed Advanced & Useful and its located in the Features section.
Removed unused internal functions for validations now used by Esmerald encoders.

Fixed¶

Regression caused by the introduction of the dynamic encoders when diplaying the query parameters in the OpenAPI documentation.
Annotation discovery for the Signature.

Changed¶

Internal implementation of the exceptions.
Removed redundant exception declaration and delegate the internals to Lilya.
Internal code cleaning.

Added¶

ValidationError for custom independent raising exceptions within any Esmerald application

Fixed¶

is_server_error for dependencies was causing an exception to be raised in a loc[-1].

3.3.2¶

Changed¶

3.3.1¶

Changed¶

Automatic detection of a response for a default status code when using OpenAPI documentation.

Added¶

Esmerald is ow using python-slugify instead of awesome-slugify for internals.
OpenAPI Schemas Pydantic is now fully integrated with Esmerald OpenAPI.
Esmerald now supports app as decorator prodiving another way of declaring the routing.

Example¶

#!/usr/bin/env python
import uvicorn

from esmerald import Esmerald, Gateway, JSONResponse, Request, get


app = Esmerald()


@app.get("/esmerald")
def welcome() -> JSONResponse:
    return JSONResponse({"message": "Welcome to Esmerald"})


@app.get("/esmerald/{user}")
def user(user: str) -> JSONResponse:
    return JSONResponse({"message": f"Welcome to Esmerald, {user}"})


@app.get("/esmerald/in-request/{user}")
def user_in_request(request: Request) -> JSONResponse:
    user = request.path_params["user"]
    return JSONResponse({"message": f"Welcome to Esmerald, {user}"})


if __name__ == "__main__":
    uvicorn.run(app, port=8000)

The same is also applied to the Router object.

New scheduler_config parameter to Esmerald and EsmeraldAPISettings.

Changed¶

Deprecate scheduler_class, scheduler_configurations and scheduler_tasks in favour of the new SchedulerConfig approach.

Breaking changes¶

You must update the imports to be:

From:

from asyncz.contrib.esmerald.decorator import scheduler

To:

from esmerald.contrib.schedulers.asyncz.decorator import scheduler

Check the documentation about the Scheduler, handlers and the SchedulerConfig to see how to update your current project to the new version with the minimum disruption.

This change should not break existing functionality, instead, its just an update to make it more modular. There is an example how to simply use this.

Fixed¶

Added missing options --settings into the runserver directive.

3.2.3¶

Changed¶

EsmeraldScheduler integration with Asyncz is not assembled before the configuration of the routing, allowing multiple events to be triggered without overriding.

Added¶

settings_module when passed in the instance of Esmerald will take precedence over the global settings, removing the need of using constantly the ESMERALD_SETTINGS_MODULE.
ApplicationSettingsMiddleware as internal that handles with the settings_module provided and maps the context of the settings.

Example of the way the settings are evaluated¶

from esmerald import Esmerald, EsmeraldAPISettings, Gateway, Include, JSONResponse, get, settings


@get()
async def home() -> JSONResponse:
    return JSONResponse({"title": settings.title})


class NewSettings(EsmeraldAPISettings):
    title: str = "Main app"


class NestedAppSettings(EsmeraldAPISettings):
    title: str = "Nested app"


app = Esmerald(
    settings_module=NewSettings,
    routes=[
        Gateway("/home", handler=home),
        Include(
            "/child",
            app=Esmerald(
                settings_module=NestedAppSettings,
                routes=[
                    Gateway("/home", handler=home),
                ],
            ),
        ),

Missing Request document.
Removed the use of random for the secrets in favour of the secrets library instead.
Contrib documentation updates regarding the Authorization headers.

2.3.1¶

Fixed¶

Middleware as an independent ASGI app on an Include level.

Warning

This was supposed to go in the release 2.3.0 but it was not merged on time to make the release.

2.3.0¶

Changed¶

OpenAPI fields are permanently moved to OpenAPIConfig making the codebase cleaner. The options are still available via settings in case of wanting to override the defaults but not via instantiation parameters. Via instantiation the OpenAPIConfig is the one to be used.

Added¶

Annotated for documentation generators.
Add new documentation structure for Esmerald base.
Add API Reference . #196

Fixed¶

Allow tags for levels. When a tag is added to an Include, Gateway, or any other level, the tags are appended to the final handler. This allows inheriting from existing tags for OpenAPI.

2.0.5¶

Changed¶

Updated the way esmerald client operates internally.
Updated internal minimum requirements.

Fix¶

Regression in OpenAPI when adding middleware to Gateway or HTTPHandler. When a middleware was added, the OpenAPI would not generate the docs for it. The API would still work but not OpenAPI docs.

Cleaner codebase for the application settings.
Updated version of Asyncz to be at least 0.5.0.

Added¶

Fixed¶

Removed old pydantic v1 syntax from tests and applications.
add_include() that wasn't generating signature models upon import.
OpenAPI query params with defaults weren't loading properly.

2.0.3¶

Note

This addition was supposed to go in the release 2.0.2 but somehow it was missed in the merge of the pull requests. It is not a bug fix but instead is a simple new directive that can be useful for those who like using the command-line.

It is important to understand that this support won't be available on releases of Esmerald 1.X.

Added¶

Interactive shell support directive for any Esmerald application.

2.0.2¶

Changed¶

Updated Field, Form and Body from esmerald.params with current defaults.

Added¶

Added strict and max_digits esmerald params esmerald.params.

File and Form from esmerald.params now accept annotation.
OpenAPI for UploadFile as single and list now being parsed as a model.

2.0.1¶

This is a small fix into the parser of lists for the OpenAPI specification.

Fixed¶

OpenAPIResponse now allows proper parse of lists as definition. More details.

2.0.0¶

Warning

When upgrading Esmerald to version 2, this also means the use of Pydantic 2.0 at its core as well as corresponsing technologies already updated to version 2 of Pydantic (Saffier, Asyncz...). If you still wish to continue to use Pydantic 1 with Esmerald, it is recommended to use Esmerald prior to version 2.0 which it will be maintained for a shor period but we strongly recommend to always use the latest version.

Changed¶

Major update of the core of Esmerald from Pydantic v1 to Pydantic v2.
ResponseSpecification renamed to OpenAPIResponse, from esmerald.openapi.datastructures import OpenAPIResponse.
Changed deprecated functions such as validator and root_validator to field_validator and model_validator.

Deprecated OpenAPIView in favour of the new OpenAPI documentation generator.
Changed OpenAPI config to reflect the new generation of OpenAPI documentation.
Internal data field is now returning Body type parameter making it easier to integrate with Pydantic 2.0.
General codebase cleanup.
Removed old OpenAPI document generator in favour to the newest, fastest, simplest and more effective approach in v2.
Remove the support of pydantic 1.0. Esmerald 2+ will only support pydantic 2+.

Added¶

Support for Ruff.
New esmerald core admin management directives #83.
New directives client.

New handlers. OPTIONS, HEAD and TRACE. Check out the handlers for more details.

Fixed¶

New Starlette Lifespan #75. This is now also available to be done in the same way Starlette does. Internally Esmerald also implements the on_startup and on_shutdown but that is an unique implementation. This implementation follows the same pattern as the official Starlette Bridge

1.0.0¶

Changed¶

ChildEsmerald now supports the parent which means it can share middlewares and interceptors across main application and children.

Note

Prior to version 1.0.0, sharing resources between Esmerald and ChildEsmerald was not allowed and it needed to be treated as completely isolated application. In the version 1.0.0 you can still isolate them but you can also share resources.

Added¶

Esmerald Pluggables #60.

This is the feature for the esmerald ecosystem that allows you to create plugins and extensions for any application as well as distribute them as installable packages.

New base_user and middleware support for Saffier with Esmerald.
New docs regarding the Saffier integration. Those include also an example how to use it.

Changed¶

Breaking change - Removed support for python 3.7. This was blocking the technology from evolving at a normal pace and blocking security patches from being properly applied.

Fixed¶

Old package versioning conflicts.

0.11.1¶

Changed¶

Improved OrJSON, UJSON, ORJSONResponse and UJSONResponse when importing dependency.

0.11.0¶

Added¶

To make esmerald more optional and feature modular, this release brings some backwards incompatibilities that should be addressed when moving to this version. Check out the dcumentation for more details if this release notes doesn't cover it all.

Changed¶

Moved UJSON, UJSONResponse, OrJSON and ORJSONResponse to be optional dependencies #45.
Changed the imports for ORJSONResponse to from esmerald.responses.encoders import ORJSONResponse #45.
Changed the imports for UJSONResponse to from esmerald.responses.encoders import UJSONResponse #45.
Changed the imports for OrJSON to from esmerald.datastructures.encoders import OrJSON #45.
Changed the imports for UJSON to from esmerald.datastructures.encoders import UJSON #45.
Moved the scheduler to optional installation with pip install esmerald[schedulers] #45.

Backwards compatibility¶

This is only applied for those who have esmerald prior to 0.11.0. If you already had template configurations, jwt, schedulers or all the features you need to update the imports to:

TemplateConfig:

from esmerald.config.template import TemplateConfig

JWTConfig:

from esmerald.config.jwt import JWTConfig

Scheduler class is now imported directly from asyncz:

from asyncz.schedulers import AsyncIOScheduler # for the Scheduler class
from asyncz.contrib.esmerald.decorator import scheduler # for the decorator

0.10.0¶

Added¶

add_apiview to the Esmerald class.
JSON, OrJSON and UJSON responses #44.
