After installing json-server by
pip install json_server
You can run
json_server <path-to-JSON-file> <port:optional>
The port argument defaults to 5000
This shall output:
* Serving Flask app 'json_server.main' (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: on
* Restarting with stat
* Debugger is active!
* Debugger PIN: 816-527-262
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
Which is similar to what a standard Flask app logs.
Now that you have run the command, http://127.0.0.1:<port>/ shall respond with your JSON.
