Answer 1

Well, I faced the same issue. For new users who may land at this page. Just follow their official documentation.

Install flask-cors

pip install -U flask-cors

then after app initialization, initialize flask-cors with default arguments:

from flask import Flask
from flask_cors import CORS

app = Flask(__name__)
CORS(app)

@app.route("/")
def helloWorld():
   return "Hello, cross-origin-world!"
