Local development

After cloning this template, run it this way:

pipenv install
export FLASK_APP=application.py
export FLASK_DEBUG=True
pipenv run flask run

The project is run through Flask and will be available at http://localhost:5000. Setting FLASK_DEBUG to True will use a local file for source data (bypassing API calls) and enable other debugging tools by default.

Other env vars that can be set:

• DASH_LOG_LEVEL - sets level of logger, default INFO
• ACIS_API_URL - Has sane default (https://data.rcc-acis.org/StnData?)
• DASH_CACHE_EXPIRE - Has sane default (1 day), override if testing cache behavior.

Deploying to AWS Elastic Beanstalk:

eb init # only needed once!
pipenv run pip freeze > requirements.txt
eb deploy

The following env vars must be set:

• REQUESTS_PATHNAME_PREFIX - URL fragment so requests are properly routed.
