npm start  # run the webpack dev server and flask server using concurrently

You will see a pretty welcome screen.

Once you have installed your DBMS, run the following to create your app's database tables and perform the initial migration

flask db init
flask db migrate
flask db upgrade
npm start

Deployment

To deploy:

heroku buildpacks:add heroku/nodejs
heroku buildpacks:add heroku/python

heroku config:set NODE_ENV=production
heroku config:set FLASK_ENV=production
heroku config:set FLASK_DEBUG=0
heroku config:set SECRET_KEY="$(openssl rand -base64 64)"
heroku addons:create heroku-postgresql
heroku labs:enable runtime-dyno-metadata

git push heroku main

flask test

Migrations

Whenever a database migration needs to be made. Run the following commands

flask db migrate

This will generate a new migration script. Then run

flask db upgrade

To apply the migration.

For a full migration command reference, run flask db --help.

Asset Management

Files placed inside the assets directory and its subdirectories (excluding js and css) will be copied by webpack's file-loader into the static/build directory, with hashes of their contents appended to their names. For instance, if you have the file assets/img/favicon.ico, this will get copied into something like static/build/img/favicon.fec40b1d14528bf9179da3b6b78079ad.ico. You can then put this line into your header:

<link rel="shortcut icon" href="{{asset_url_for('img/favicon.ico') }}">

to refer to it inside your HTML page. If all of your static files are managed this way, then their filenames will change whenever their contents do, and you can ask Flask to tell web browsers that they should cache all your assets forever by including the following line in your settings.py:

SEND_FILE_MAX_AGE_DEFAULT = 31556926  # one year
