FastAPI And Babel

FastAPIAndBabel allows you to easily use babel in your FastAPI projects and offers some features to improve and ease things.

Install

You can either download the source code of this repository or install it via pip:

pip install fastapi-and-babel

Usage

First, we create an instance of FastAPIAndBabel in our program as shown below ‍‍‍

from fastapi import FastAPI
from fastapi_and_babel.translator import FastAPIAndBabel


app = FastAPI()
translator = FastAPIAndBabel(__file__, app, "en")

We create the following mapping file babel.cfg

[python: **.py]

Save the file and then run the following command

pybabel extract -F babel.cfg -o messages.pot .

babel uses this file for mapping and stores the patterns in messages.pot

pybabel init -i messages.pot -d translations -l en

Here -d says to save translations in translations, you can change it in config

After adding your messages, use the following command to compile

pybabel compile -d translations

Now we can translate our texts using the gettext method

from fastapi_and_babel import gettext as _

@app.get("/")
def index():
    return {"text": _("Hello World!")}
