Google Maps

We need some advice about the map services provider. We are a mobility app that just launched 5 months ago in Tunisia offering P2P carpooling. We are currently using Google Maps API for maps (Places API, Geocoding API, Directions API & Distance Matrix API). Thus, we received expensive bills from Google Cloud following the number of requests we are using. We are looking forward to reduce the number of requests in general because we can't afford these large bills at this stage, knowing that they are going to increase proportionally to the active users of the app. We tried to optimize multiple times but it isn't enough. We are searching for optimization advice or ideas on how we use the APIs, or other map providers (like OpenStreetMap or similar) that offers free or cheaper options than Google Maps, without lacking quality of information (we are in Tunisia and we have to choose options that have enough data about Tunisia). Thanks!

A huge component of our product relies on gathering public data about locations of interest. Google Places API gives us that ability in the most efficient way. Since we are primarily going to be using as google data as a source of information for our MVP, we might as well start integrating the Google Places API in our system. We have worked with Google Maps in the past and we might take some inspiration from our previous projects onto this one.

Replacing Google Maps in a medium size GIS Application for public sector...

For a small mobile app that uses mostly localization, to display Google Maps with hotspots nearby, which Cross-Platform would you prefer and why? It will make requests to a Sails.js app.

I need to implement a web application with a sidenav "drawer".

It's a very common UI nowadays. For example, Google Maps has a collapsable sidenav on the left that shows a "drawer": inside the drawer, things can be pretty complex and interact with the main screen. Also, Google Slide has one if you choose format options.

I'm not sure which frontend framework to use. AngularJS alone will be enough? Or is there something else on top? Any useful boilerplate? I need to concentrate on the features, not much on technical details.

I want to make a delivery logistics web app for a small business that will run on our local server that uses Google Maps API and I’m wondering what would be the best language for that.
