why can't i deploy react flask app on heroku?

由 百般思念 提交于 2021-02-05 12:01:46
问题 Newbie here again asking another question. This time is more about Heroku itself. So, I have a project built with react for the main front-end and Flask as an Internal API. So far, Flask is deployed on Heroku fine, endpoints working as expected. However, i am having a difficult time on deploying the React files on Heroku with the FLASK server deployed already.. Googled, came across some good resources but no luck on implementing any idea or how to go about it. Main issue is how can i tell

Use a production WSGI server instead. * Debug mode: on * Restarting with stat *

I expect that a user could access the products data without being authorized (as a guest), but it certainly needs to be logged to access to a pay view or for buying something. So how could I get this? Oauth (which flow type), basic authentication, cookies. Which steps do I
