Timezone lookup using latitude and longitud (part 2)

jms — Wed, 12 Aug 2020 00:00:00 +0000

For the fastapi project we are going to use Sqlalchemy and postgresql taking some reference from the fastapi documentation.

        
# create a virtualenv, with any tool: poetry, pipenv, virtualenv module, etc 
pip install fastapi uvicorn aiofiles SQLAlchemy psycopg2-binary

First timezones are evil, but sometimes you need to work with them. Sometimes is easy to consume some third party api to get timezone information based on a given location using geocoding but there also exists some alternatives.

Then inspired on this blog post and the project Timezone boundary builder decided to create a test project using fastapi and postgis to do the timezone lookup using the latitude and longitude.
