| Single-Page Applications | |
| ======================== | |
| Flask can be used to serve Single-Page Applications (SPA) by placing static | |
| files produced by your frontend framework in a subfolder inside of your | |
| project. You will also need to create a catch-all endpoint that routes all | |
| requests to your SPA. | |
| The following example demonstrates how to serve an SPA along with an API:: | |
| from flask import Flask, jsonify | |
| app = Flask(__name__, static_folder='app', static_url_path="/app") | |
| @app.route("/heartbeat") | |
| def heartbeat(): | |
| return jsonify({"status": "healthy"}) | |
| @app.route('/', defaults={'path': ''}) | |
| @app.route('/<path:path>') | |
| def catch_all(path): | |
| return app.send_static_file("index.html") | |
