Hey everyone,
I’ve been working on a project and I’m stuck. I made a login and signup page using HTML and AngularJS. That part was okay. I also set up PostgreSQL as my database.
Now I’m trying to figure out how to get the data from my AngularJS front-end to my Node.js back-end, and then into PostgreSQL. I’m not sure about the right approach here.
Has anyone done something similar? What’s the best way to handle this data flow? Any tips or examples would be super helpful.
Thanks in advance!
For sending data from an AngularJS front-end to a Node.js back-end with PostgreSQL, I’d recommend using RESTful API endpoints. Create a service in AngularJS that uses $http to make AJAX calls to your Node.js server. On the server-side, set up Express.js to handle these requests, process the data, and interact with PostgreSQL using a library like node-postgres or Sequelize.
Ensure you implement proper data validation and sanitization on both the client and server sides. For security, use HTTPS and consider implementing token-based authentication. Also, structure your API to follow REST principles for consistency and scalability.
Remember to handle errors gracefully and provide meaningful feedback to the user. This approach offers a clean separation of concerns and allows for easy maintenance and future expansion of your application.
hey there! have u considered using websockets? it might be a cool way to send data in real-time between ur angularjs frontend and node backend. how about socket.io? it’s easy to set up and works great with postgres. what kinda data r u sending? we can brainstorm?
hey luke, i’ve done smthing similar. use $http in angularjs to send POST requests to ur node.js server. set up express routes to handle requests. then use a postgres client lib like pg to insert data into ur db. sanitize inputs and handle errors. good luck!
