To get you started check out roslib to connect to your ROS server. It's important you have Ros3djs installed to provide the visualization in the browser.
These docs provide a decent tutorial to get you started. Also make sure you have the rosbridge websocket to connect to your ROS instance in the web browser.
Finally if your robot is not already moving you can use the joint state publisher gui to provide a quick and easy way to update the joint positions.
I was able to set up rosbridge WebSocket. I did take a look at the joint state publisher GUI, but I was hoping to build a standalone web app. So basically anyone should be able to access the web app, view a 3d map, move the robot to the desired location without making any installations on their system. I am building this app with a drone in mind so I won't be able to use the nav2djs for it either, as it would require taking off, move to a particular altitude, forward, backward, or land. Is there any other package that I could use?
Package to move the drone to a specific location? Not sure about that. You may be able retrieve the point in the scene the user clicked by implementing this SO answer
Advertise a service in ROS that takes a requested location and move the drone. From the web app call the service with the desired position. If the joint_states topic is updated correctly then it should be reflected in the web app viewer
