Serving Angular front end with Flask does not render images
In server.py, add a static_proxy to ensure that supporting files are served.
from flask import Flask, send_from_directoryapp = Flask(__name__)@app.route('/<path:path>', methods=['GET'])def static_proxy(path): return send_from_directory('./', path)@app.route('/')def root(): return send_from_directory('./', 'index.html')if __name__ == '__main__': # This is used when running locally only. When deploying use a webserver process # such as Gunicorn to serve the app. app.run(host='127.0.0.1', port=8080, debug=True)@app.errorhandler(500)def server_error(e): return 'An internal error occurred [main.py] %s' % e, 500Additional resource

Extra note from asker
In order to be able to make requests from the Flask server serving the angular front-end to itself, in app.run() you must also set threaded=True.
