How To Make an App Like Uber in React Native | Geolocation Tutorial
Taxi apps such as Uber, Lyft, Didi or Ola have been extremely popular in the last couple of years, and that is highly correlated with the fact that the cost of building a mobile app like Uber, with Maps and Geolocation Tracking functionality has decreased dramatically. At Instamobile, we offer high-quality React Native Templates to help developers start their app faster. In this React Native tutorial, we are going to learn how to make an app like Uber in React Native, by leveraging the react-native-maps package, which is compatible with both iOS and Android.
It is used for geolocation functionalities, such as location, geofencing, map directions, trajectory monitoring, and GPS tracking.
Drawing simple polylines along the route that the device travels. The library ships with platform native code that needs to be compiled together with React Native. This requires you to configure your build tools accordingly. The actual map implementation depends on the platform.
Then, you can install react-native-maps package, by running the following npm command: npm install react-native-maps --save Here, we install react-native-maps by following the official installation instructions. You should see a simple map displaying the current device location as a random place on earth. As a result, you will see the following screen in your project simulator.
Retrieving the Device Geolocation in React Native In the next step, you need to fetch the current device location. To implement this feature, which is supported in all Taxi apps, you need to add the following code snippet. You can try to change location mode in the Debug Menu: To visualize the result, you can open the Debug Console in Chrome: Here, we can see live the data feed from the marker function. Now, by using the feed data, we can set the state as follows: navigator. You have completed the basic Taxi app functionality in your own React Native project.
From the official tutorial, you need to create an array of latitudes and longitudes. For that, you can create a new state variable name routeCoordinates and set its type to a blank array: this. Second, you need to create a new position element Third, you need to concatenate the old and new arrays together.
You should see a route path as in the image below: Showing the Traveled Distance in React Native Computing the traveled distance is a core feature of Taxi apps like Uber, since car sharing apps charge their riders based on how much that distance is. We need to configure how far we are moving to showcase the traveled distance. However, the complicated scene occurs when you need to deal with the earth curve. For calculating the distance between latitude and longitude you need to use the Haversine formula.
Install haversine npm package using the following command: yarn add haversine.
10 Best React Native Apps
Like launching any new product, building out a food delivery network came with its fair share of engineering triumphs and surprises. Although tasty, this new flavorful passenger food! For instance, it cannot specify its preferred route or chit chat with the driver and it does require more steps at pickup and dropoff.
In this article, we focus on one challenge in particular: how Uber Engineering handled introducing a third party to what had previously been a two-sided marketplace. A trip became a delivery.
Driver-partners became delivery-partners, and riders became eaters. But there was no analogous party to the restaurant, because for the past five years the assumption had been that there would only be two people involved in a single trip; not three people and one cheese pizza, order of Pad Thai, or chicken fajita. Restaurants need a way to communicate with both delivery-partners and eaters. Figure 2: A Restaurant Dashboard showing one active order. Over several months, it became clear to us that in order to continue improving the Restaurant Dashboard, a complete revamp would be necessary.
Our web app only provided limited access to the device, which proved to be a significant problem because it restricted our ability to communicate important information to restaurants. One example of this is that a user must interact with a web page before sound-based notifications can be cued. Restaurants are bustling with activity, so sound is a hugely important way to notify restaurant employees about the placement of a new order or when a delivery-partner has arrived to pick one up.
To solve this issue, we displayed a modal each time the page was loaded in order to force user interaction. While this gave us implicit permission to play sound, it did so at the expense of the user experience. Figure 3: Restaurant Dashboard showing a modal to force user interaction and therefore enable sound.
We also needed to build some features that simply were not feasible on a web browser or were only available in a highly constrained format. For example, printing physical receipts is a given for many restaurants, but web browsers only permit the function for those that use AirPrint -compatible printers. This limitation was a great source of confusion and frustration for restaurants and engineers alike. We realized that in order to overcome this hurdle, we would need access to the hardware, which would allow us to communicate directly with printers using native SDKs provided by printer vendors.
There was also a wealth of knowledge about how the restaurant component of the service functioned, which we had accumulated by working on UberEATS since its inception. These considerations made React Native, which provides a platform for mobile development in the language of the web, a compelling option.
Multi-platform support was also a big concern for us. Currently, Uber works closely with restaurants to find tablet devices and install the Restaurant Dashboard app, but this practice may become less sustainable as UberEATS continues to expand.
The driver-partner side of Uber went through a similar shift when we moved to a BYOD bring your own device model. By structuring the UberEATS app in a platform-agnostic manner we have the option of expanding to Android later and supporting both platforms moving forward. For React Native to be a viable option for us, it was also important that it work within our existing mobile infrastructure and support the kinds of features that had originally prompted our move towards a native application.
Building a Migration Path The initial goal was to build the bare minimum amount of scaffolding needed to get Restaurant Dashboard running natively.
In order to accomplish this, we created a native navigation and authentication system along with a WebView pointing to our existing web app. Figure 4: The above diagram showcases interaction between the native and web Restaurant Dashboard Flux stores. This gave us a lot of flexibility in terms of gradually migrating functionality. Having this minimal viable product MVP effectively at feature parity allowed us to rapidly start testing on real restaurants. We integrated with several native printer SDKs to expand the range of compatible printers beyond those supported by AirPrint.
With this functionality also comes the patterns and concepts of the mobile and web communities, respectively. This melting pot of ideas gives us more options, but also presents new challenges in terms of choosing the right abstraction. Fortunately for our needs and preferences, web concepts and technologies on the whole translate quite nicely to native development.
On the web, Restaurant Dashboard uses the popular react-router library which enables routes to be defined declaratively, much in the same way as a View. However this system assumes the existence of URLs which tend to be lacking outside of the browser. React Native provides an imperative navigation library, which resembles the interface provided by UINavigationController. For the sake of speed, we initially kept the react-router library with the aim of replacing the routing framework once an MVP was up and running.
In the context of UberEATS, a bad update refers to a bundle update causing Restaurant Dashboard to crash before the bundle handling logic has a chance to run.
The timing of the crash would make it impossible to fix the problem by pushing a new bundle. Updates causing this type of instability will happen eventually so it is important to have a resilient system which can detect and recover from unstable builds. One way of avoiding the deployment of bad updates is to treat every release as an experiment, which allows for a gradual rollout and, if necessary, a rollback of updates.
If the most recent bundle can be loaded, it graduates to being the safe bundle. In the event that no safe bundle exists, the original one remains in use with no updates. This method of updating Restaurant Dashboard has significantly less friction than a regular mobile app update because new builds can be released as needed, cutting down the time to ship a new feature from a matter of weeks to days. Updates are downloaded in the background and loaded once complete, avoiding user interaction.
This lack of immediate user interaction enables updates to be propagated faster and that a majority of devices can be kept on the most recent build. The same mechanism also allows us to quickly roll back bad builds, minimizing the disruption to restaurant partners. While pushing updates in this manner has not completely replaced normal app releases which are still occasionally needed for changes to the iOS or Android native code , it has reduced their frequency.
As the native layer matures with the project, we expect this trend to continue. Testing and Type Checking Within Uber Engineering, teams move fast and web projects tend to ship as changes are pushed to the repository rather than waiting for a build train.
This stands in stark contrast to the multi-week release processes typically associated with mobile applications. When we contemplated shifting to a native application during the development of Restaurant Dashboard, we were concerned that the stability of the application might suffer due to this tight turnaround; after all, if you crash in the React Native interpreter, you crash in real life. Even with bundle pushes providing a way to reduce this risk, crashing is far from ideal.
Indeed, it has proven to be an invaluable tool for testing code and catching errors before they reach production. As detailed below, a reducer takes the current state and an action as input, and in turn, it is expected to return a new state as output: Handling Side Effects Using Flow to type check allows us to verify that our state maintains its correct shape after this process, and it is a credit to the Flow community that new releases have continued to find possible sources of bugs in our application.
Furthermore, the minimal overhead associated with optional typing means it does not get in the way of rapid iteration and development. Restaurant Dashboard uses Redux for managing the flow of data. Redux provides us with a simple, predictable way to model application state by following a few key principles: All state is in the store, which is a single immutable object Views take the store as input and render React Native components The View can dispatch actions, which are requests to modify the store Reducers take the action and current state as input, returning a new store It is often necessary to alter the store in response to asynchronous actions, such as network requests.
Redux does not prescribe a way of doing this, but a common approach is to use Thunks , a middleware for Redux that allows actions to be functions that return a promise and dispatch additional actions along the way. Figure 7: In Restaurant Dashboard, data flows through a Redux application.
Our initial approach was to use Thunks, but we quickly ran into problems as our application logic and side effects became more complicated. Specifically, we encountered two side effect patterns that did not naturally fit into the Thunk model: Periodic updates to application state Coordination between side effects Sagas , an alternative side effect model for Redux apps, leverage ES6 ECMAScript 6 generator functions to provide a less complicated option.
Rather than extending the concept of an action, they are modeled as a separate thread which can access the store, listen to Redux actions, and dispatch new ones. No endless saga here! One area where Sagas really shine is in the management of periodic changes in application state, such as retrieving a new list of active orders.
This is achievable using Thunks, but is far from elegant. Who would have thunk? Not us!

They receive contact information as well as other useful information, such as license plate number, car make, location on a map, etc. They can also chat or call to clarify some details. Payment When registering, the user indicates the most comfortable payment methods. The more features your application provides, the better.
How to create an app like Uber: React Native app development cost
The required minimum is bank cards and cash. But you can also add the ability to make payments using mobile wallets, online banking, QR codes, etc. Lyft: adding a new payment method or promo codes Rating At the end of the trip, both parties can rate each other. When developing an application, it is important to ensure the transparency of this system to avoid bias and negative comments. Think about what algorithms will be incorporated into this process to motivate drivers.
For example, a bad rating can affect the number of orders and the size of the commission, and sometimes even the dismissal. Tech Support This option is necessary to stay connected with both passengers and drivers regardless of their rides. It is an opportunity to leave a claim, share new ideas on improving the app, or lost search ads. Support service of Uber: they have no problem! How does Uber work?
The first thing that makes Uber so popular among 80 million users is its outstanding service. One tap on the phone and you have a personal driver who will pick you up in a few minutes. On the one hand, this influence on the market is called destructive.
But Uber has set the bar high that other companies are just trying to reach. This will increase the React Native app development cost but you cannot start without it. Booking interface: As soon as the user opens the application, he sees a screen with a field for entering the address, choosing the type of taxi, and setting a specific landing spot. Price calculator: If one wants to know the estimated cost from point X to point Y before ordering, the price calculator is here to help.

Payments: There are several payment options, such as credit card, cash, Uber credits, and certificates. Any time one needs, one can check previous bookings, rate them, leave a review. One should verify the tax number and wait for approval by an administrator. Uber app also provides drivers with online status and schedule. They also have access to the booking history. Push notifications: They are necessary for order updates and their completion.
Navigation: Drivers do not need to install other navigation apps because Google Maps or Google Places provide them with optimal directions just in the Uber app. They could also be voiced. Technologies are used to build an app like Uber You probably know that Uber does not hide its API at all, and therefore there is no difficulty in building a similar application.
You will need three giant basics like server, mapping, and payments. These affect React Native app development cost. First off, it is impossible to process all user requests, driver routes, and other data without your own server. Developing the backend, you may use Node. Take care of the tech stack for push messages as well. How to estimate React Native app development cost?
First of all, make sure you know the pros of the framework. Choosing the solution for the app development, we would recommend you to rely on React Native primarily.
