This tutorial aims at integrating the google maps API to your React components and enabling you to display maps on your website. For a basic Google Map, this is literally all the code you need. Go ahead and run your app and ensure that the map loads to the browser. First we need to import Marker and infoWindow components from the google-maps-react library inorder to help us achieve loading of the two. Sidenote: the visibility of the infoWindow is controlled by the boolean visible prop which shows the InfoWindow component when true and hides it when false.
As a follow-up practice, you can go and add a few more markers on your map and more interactivity to your infoWindow. In our src folder create a new file and name it Map.
This is handled by the boolean prop centerAroundCurrentLocation. Map instance to change the center of the map. Next, we need to handle the instance when the map has already loaded.
This will be handled by the componentDidMount Lifecycle method which will set a call back to fetch the current location. The loadMap function is only called after the component has been rendered and grabs a reference to the DOM component to where we want our map to be placed. Our CurrentLocation component is almost looking up, But we need to ensure that our previous Marker picks our current location ie the browsers current location and so we need to introduce Parent-Child concept through the renderChildren method which will be responsible for calling the method on the child component.
Read more about Parent-Child communication here. Lastly, before we wind up we need to update our MapContainer component to include our new changes. We also made the map pick our current location. From here, you can implement more advanced features such as having polylines and polygons or adding event listeners into your maps.
Having both the frontend and backend together like this reduces the effort it takes to make a web server.
Build rich map experiences with Mapbox and React 🗺 🚀
In this tutorial, you will learn how to build web servers using the http module that's included in Node. In this guide, we will show you three different ways of getting Node. These allow developers to initialize a function with default values if the arguments are not supplied to the function call. Initializing function parameters in this way will make your functions easier to read and help you avoid errors caused by undefined arguments and the destructuring of objects that don't exist.
In this article, you will learn how to use default parameters. Twitter Facebook Hacker News. DigitalOcean home. Community Control Panel. Hacktoberfest Contribute to Open Source.Mapbox provides a collection of APIs to add directions-related services to your application.
From routing deliveries efficiently to providing navigation steps for wayfinding, Mapbox provides the tools necessary to integrate directions into your application. This guide provides an overview of how the routing network is created, how to add directions services to applications across platforms, how to provide feedback, and relevant documentation to help you get started.
Type in two locations to view the raw JSON response for that query. When using the Mapbox GL Directions plugin, all this information will be automatically added to the map when a request is complete.
By default, the plugin will also display turn-by-turn instructions. This example hides the turn-by-turn instructions and displays the raw JSON response to illustrate what information is included in the directions response object. When you provide two or more points to the Mapbox Directions API, it returns a route as a GeoJSON line that you can add to your map, text for turn-by-turn instructions that you can choose to display in your application, and the distance and estimated travel times for the mode of transportation you selected.
There are many other services that extend Mapbox directions that allow you to fix messy GPS traces to the network or optimize trips to multiple stops on a single journey. The Mapbox routing network can create routes and optimized trips, and is used to calculate the most efficient path for a given mode of transportation driving, cycling, and walking. The routing network includes a robust network of roads and paths also known as ways with distinct attributes like speed limits, turn lane restrictions, mode of travel, and accessibility for bikes and pedestrians.
A way is an OpenStreetMap term used to describe an ordered list of nodes points which normally also has at least one tag, or description. For the purposes of the Mapbox Navigation service APIs, ways can be roads, foot paths, or bicycle lanes. The time it takes to travel from one point to another is determined by many factors, including:.
Read more about our traffic tileset in Our map data. Traffic data collected in these countries is comprehensive across geographies and times, resulting in highly accurate travel times. Traffic data collected in these countries is less comprehensive.
Travel times may be inaccurate, especially in heavy and unusual traffic conditions. Travel times are less reliable, with partial coverage of traffic conditions. There are many tools you can use to enable directions-related services for your Mapbox web or mobile application.
You can access these services directly using the web services APIs, through our Navigation SDK, or using one of several plugins and libraries to integrate these services into applications across platforms.
Requesting directions from the Mapbox Directions API requires at least two waypoints — an origin and a destination — but can also include up to 23 additional waypoints between or a total of 25 waypoints. When making a request, you can specify additional parameters such as which profile to use walking, cycling, driving, or driving with traffic and whether alternate routes should be included in the response.
You can also add optional annotations to your request, including duration, distance, speed, and congestion. We calculate congestion by comparing night-time traffic speeds with real-time traffic speeds and assign a level of congestion given the percentage difference.
You can read more about the directions response object in our API documentation. Each location is either a source or destination. The number of sources and destinations are multiplied to create the matrix, or timetable, and calculate the number of elements needed to make the request. The Matrix API will always return the duration on the most efficient route for each location in the matrix, where an element is an origin-destination pair in the matrix.

Question feed.If you are a developer and had to build a web map you probably came across the question of selecting wether you go for a DOM or WebGl map.
In this article, I will develop on the second option which to me open new doors for developing rich map based applications. For a bit of context before diving in a use case application, a WebGl map bring the possibility to render vector tiles on the client side, this way we get all the data accessible on the browser and we can interact with pretty much everything on the map.
Vector maps are also lighter than image tiles based maps, they render fast and provide smooth zoom interpolation. Knowing this, I would like to talk to you about a side project I have been working on, where the idea would be to display all the UNESCO sites in a rich vector based map application.
I think it is a good real world example of map we could find out there in term of complexity and user experience. The use case is actually close to the Airbnb one with a side by side list of flats also represented on a map. We have been working with React and Mapbox on this project and it has been a pleasant developer experience.
Mostly because all the tooling exposed by Mapbox are very well integrated between each other which make everything smooth and simple to use. Not only, the result is really pleasant too with a user experience which feel really natural compared to any average map found on any web application using DOM map leaflet … rather than WebGl map. Beforehand I would like to thanks three friends I have been working with for the project.
Note: If you are not interested about the process to get the data, you can jump to the next section. First of all we needed the right data after some exploration we found the UNESCO would provide an XML we could use to get all the different places locations, name and a descriptionunfortunately there was no way for us to get also get the images from the UNESCO because of a restricted license.
We would then use the title of each site from the XML as a search query to retrieve the images on Flickr. So far we had no time to improve this point but we identified two ways to get a search with more results from Flickr:. Then for most of the sites missing an image we would display a placeholder image:. With the data sorted and ready to be queried, we could move on and design the map on mapbox studioa web application made by Mapbox that provide the possibility to style all the data of a map.
From colours of the building to the width of the roads or even controlling the style depending on the zoom value, you can literally play with each elements of your map. To me it is an essential tool if you want to make the best map experience.
Note: Having an highly customisable map is only possible because of the vector tiles which bring more flexibility when it come to play with the different shapes. Also the map style can be modified on the fly at runtime of your application. At this point it is important to think what data you integrate with Mapbox studio and which ones you want to control at runtime in your application.
For this application it seemed obvious, the data to build the map itself Mapbox geographic information mostly built on top of OSM would be passed down using the Mapbox style you can get by exporting from Mapbox studio as an URL or JSON.Knowing the similarities and differences between Google Maps and MapBox within a React app will help you pick the right tool for the job. This article compares and contrasts these two popular libraries, getting you up and running with whichever one you choose.
Airbnb, Uber, Realtor, and so many other websites provide a map view of their data. Unsurprisingly, it's the easiest way to visualize geographic data, which many apps have. A problem arises, though, when you read the documentation for the two most popular mapping libraries: Google Maps and MapBox. You won't find documentation for how to easily use them within React, the most popular frontend framework.
In this article, we will see how to display data on a map within React, showing examples with both Google Maps and MapBox. The final Google Maps version and MapBox version can be found here. If you'd like to follow along with a video, check out the Google Maps and MapBox videos I have posted. Ottawa, the capital of Canada, has a great set of open data for their city. In this example, we will be working with data showing where all the city's skateparks are.
The entire JSON file can be found herebut I have stripped out the fields we aren't using to show a small sample of what it looks like. The most important thing, and a requirement to place anything on a map, is a location's latitude and longitude. In the example below, the coordinates property has an array where the longitude is the first element, and latitude is the second.
We will be using a React library called react-google-maps to help us integrate React with Google Maps. After installing it, the next thing we need to do is grab an API key. This can be done within the Google Developer Console.
You should be fine with a free account as long as it's just a personal project or for a demo. Rather than placing our API Key inside our code, let's use an environment variable to make it available. We'll place it in a file called. The first component we will build is the Map component. Its purpose is to render the data inside of the GoogleMap component, which comes from the package we installed. It doesn't require any initial props, but passing in the zoom level and where to center the map are pretty typical.
With the Map component rendering the GoogleMapit's time to put some data inside of it. We are importing our data from a local JSON file, but you could just as easily load it from a remote API within a useEffect hook when the component is mounted. The idea is to loop through each of the skateparks, rendering a Marker for each one.
Display driving directions
The key prop is always necessary when you are mapping an array in React, while the position says where to place it. The icon prop isn't necessary, but it lets you override the typical red marker with something custom of your own. With all of our markers being shown, we can now handle when the user clicks one of them. What we're going to do is use some state with useState to know which marker was clicked, showing its details inside of an InfoWindow popup.
An onClick prop has been added to each Markersetting that park as the selectedPark in state. Below the markers, we check if there is a selectedParkand if so, show an InfoWindow with all of the details of the selected park. This component also requires a position, and an onCloseClick prop to know what to do when the user closes it. We're almost there!
The last step is to use this Map component. The MapWrapped component needs to be inside of a div that has some dimensions. Mine takes up the whole screen vh and vw. We're required to pass it the googleMapURLwhich includes the API Key mentioned earlier, along with three elements which are used internally by the package.
If the standard styles are too boring for you, head on over to Snazzy Maps and grab the JS for your favorite style.That way the idea of playing a bit with maps libraries came to my mind. I knew some cool map libraries for React but I have never used them with data visualization tools on the top of it. With these goals I decided to start a small project mainly using react-map-gl and deck.
At this point I got the tools but… what data can I use and where I can take it from? The only way I found was downloading my whole location data using their data liberation project called Google Takeout. With it you can download your own data of some google products. In my case I just wanted location history for this project.
I decided to simplify the location data and load it directly in the project avoiding the usage of any external service for querying it. Inside the JSON file I got an array of objects with properties like longitude, latitude and timestamps as shown in the following snippet so I got everything I need to start coding.
I started a simple react project using create-react-app tool.
For complex projects I have my own template with my custom configurations about Redux or routing. Having my base app as the starting point of the project, I removed some template stuff like example components and styles that I got as the output of create-react-app. Then I installed react-map-gl library to start rendering some maps. As part of the configuration process I had to create a free project in Mapbox website just to get an Access Token as Uber library depends on it.
But at the end I used some basics styles and only an extra component for navigation control. So then, render function returns the following:. Last step and the most interesting one was data visualization with Deck. I had all my data and my map ready so I was looking forward to having my data rendered on the top of it. For all the location points I used GridLayer class as it was the better one according to my needs. The performance was better than I expected as I was rendering more than 60k location points read directly from a JSON file.This tutorial aims at integrating the google maps API to your React components and enabling you to display maps on your website.How to add markers to a map with Mapbox GL JS
At some point of our lives, we've all gotten a chance to use and interact with the google maps, either through finding directions, viewing our current location, ordering cabs or estimating distance and time from one point to another. Including the Google maps API in a React App is actually far much easier than expected due to its rich documentation which I highly suggest that you look into, and the npm package by Fullstack React. Go on ahead and grab your API key here.
PS: Do not be hesitant of adding your billing info as the Google cloud platform offers you a month free trial period and will not bill you after the trial period until you give your permission. For some quick setup, we are going to use facebook's create-react-app which saves us the hassle of having to configure webpack or babel. Let's go on and edit our src folder and remove files and imports that we do not need ie. We will need to edit our App.
For a simple Google Map, this is literally all the code you need. Go ahead and run your app and ensure that the map loads to the browser. The Map component takes in some optional props such as style the CSS style objectZoom number value representing a tighter focus on the map's center and initialCenter an object containing latitude and longitude coordinates.
Alternatively, the GoogleApiWrapper HOC can be configured by passing a function that will be called with the wrapped component's props and should return the configuration object like so. Wouldn't it be exciting to have a Marker and an infoWindow on our map showing our set initialCenter position? So let's add this functionality to our code. First we need to import Marker and infoWindow components from the google-maps-react library inorder to help us achieve loading of the two.
Sidenote: the visibility of the infoWindow is controlled by the boolean visible prop which shows the InfoWindow component when true and hides it when false. Let's complete our component by adding our Marker and InfoWindow components to our render method.
Let's spice things up by having our map pick our browser's current location. We will be using navigator which is a read-only property that returns a Geolocation object that gives Web content access to the location of the device. In our src folder create a new file and name it Map. We will begin by adding some default props to our CurrentLocation component, since we will need to set the map with a center incase the current location is not provided.
This is handled by the boolean prop centerAroundCurrentLocation. Let's also update our CurrentLocation component to cater for the instance when the Map is first loaded as we cannot solely depend upon the google API being always available, hence we need to check if it's loaded. And also check if the browser's current location is provided and recenter the map to it. Let's define the recenterMap function which only gets called when the currentLocation in the component's state is updated and uses the.
Map instance to change the center of the map. Next, we need to handle the instance when the map has already loaded. This will be handled by the componentDidMount Lifecycle method which will set a call back to fetch the current location.
Basically, the loadMap function is only called after the component has been rendered and grabs a reference to the DOM component to where we want our map to be placed. Our CurrentLocation component is almost looking up, But we need to ensure that our previous Marker picks our currenct location ie the browsers current location and so we need to introduce Parent-Child concept through the renderChildren method which will be responsible for actually calling the method on the child component.
Read more about Parent-Child communication here. Lastly, before we wind up we need to update our MapContainer component to include our new changes.
So let's change it to this. In this article we've been able to load our google maps React component, add a marker and have an infoWindow onto it and also have the map pick our current location. While we did not dive into adding more functionalities to our map such as, having polylines and polygons or adding event listeners, I highly recommend that you look into them.
