Want to make a Flask site with Replit authentication? Here’s how!
Basic app with auth
Here’s a basic Flask application:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def index():
return 'Hello!'
if __name__ == '__main__':
app.run('0.0.0.0', 80)
Now let’s use replit.web to add authentication:
...
from replit import web
...
@app.route('/')
@web.authenticated
def index():
return f'Hello {web.auth.name}!'
...
If you want a custom login page:
...
@app.route('/')
@web.authenticated('Please log in: <script authed="location.reload()" src="https://auth.util.repl.co/script.js"></script>')
def index():
...
User store
replit.web comes with a DB, the user store. Here’s how you can use it:
...
users = web.UserStore()
@app.route('/')
@web.authenticated
def index():
users.current["visits"] = users.current.get("visits", 0) + 1
return f"Hello {web.auth.name}! You have visited this page {users.current["visits"]} times.'
...
You can read the blog post about replit.web here and find documentation here.
