Par exemple, si vous devez le stocker dans une base de données.

Pour cela, **FastAPI** fournit une fonction `jsonable_encoder()`.

## Utiliser `jsonable_encoder` { #using-the-jsonable-encoder }

Imaginons que vous ayez une base de données `fake_db` qui ne reçoit que des données compatibles JSON.

are subject to change. They can be modified in any way, or even
removed, at any time. If your code is a library itself (i.e. it is
used on the CLASSPATH of users outside your own control), you should
not use beta APIs, unless you [repackage] them. **If your
code is a library, we strongly recommend using the [Guava Beta Checker] to
ensure that you do not use any `@Beta` APIs!**

manage.bat(sh) => 24 (sql2entity):
A execution command of Sql2Entity task
which generates classes corresponding your outside-SQL files,
for example, entities, parameter-beans to specified
directories by DBFlute properties on "dfprop" directory.

manage.bat(sh) => 0 (replace-schema):
A execution command of ReplaceSchema task
which creates your tables and loads data by
resources located to the "playsql" directory.

Et pour communiquer en utilisant WebSockets avec votre backend, vous utiliseriez probablement les outils fournis par votre frontend.

Ou vous pouvez avoir une application mobile native qui communique directement avec votre backend WebSocket, en code natif.

Ou vous pouvez avoir toute autre façon de communiquer avec l'endpoint WebSocket.

Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.
