How to add a custom Mapbox map style to your React Leaflet App

Learn how to add a custom Mapbox map style to your React Leaflet app. We’ll walk through how to create a new map using Mapbox Studio, configure the endpoint with your new style and API key, and add that map as a tilelayer in a React Leaflet and Gatsby Starter Leaflet app. How to add a custom Mapbox map style to React Leaflet and Gatsby Starter Leaflet

#reactjs #gatsby #javascript #webdevelopment…

[holytheoristtastemaker]

What are we going to build? We’re going to walk through creating a new basic Mapbox style in our Mapbox account. Once created, we’re going to use their Map API to add a custom basemap to our React Leaflet app. Gatsby Starter Leaflet with Mapbox basemapFor our map, we’re going to use this Leaflet Gatsby Starter I created that will allow you to easily spin up a new mapping app. Before we spin that up though, I’ll walk you through how to add it using only React Leaflet components. A mapping app? Yup! Maps are used all around the world to study datasets for geographic locations. They're important tools for scientists and others that are trying to help the world. Coronavirus (COVID-19) custom mapIf you want to learn more about building a map and adding data to it, you can check out some of my other articles first such as creating a Coronavirus (COVID-19) map or a Summer Road Trip map as well as a little bit of inspiration about why Anyone Can Map. What is Mapbox? Mapbox is a mapping platform that allows its customers to create custom mapping solutions. They also leverage a variety of APIs that provide powerful capabilities for building map features. mapbox.comFor our purposes, we’re going to utilize their Map API, specifically their Static Tiles API, to serve a custom map style that we create. Part 1: Creating a custom Mapbox style To get the look and feel that we want for our map, it’s important to have a basemap that helps make our data present itself without distractions. Plus, sometimes it’s fun to have a custom map. Mapbox account The first thing we’ll need to set up our custom Mapbox style is to have an account. I'm not going to walk you through that process, but you can head over to Mapbox’s website where you can sign up for free: mapbox.com Creating a new custom style Creating a new style in Mapbox isn’t as hard as it sounds. While it can get really complex if you want something unique, we can copy one of Mapbox’s default styles to get started. First, head over to Mapbox’s Studio dashboard by clicking your account link in the top right corner when logged in. Mapbox StudioOnce we’re on our Studio dashboard, we want to select the New Style button. Create a new style in Mapbox StudioAfter clicking the button, a modal will pop up allowing you to choose a template. You can choose whatever you want here, but I’m going to choose Monochrome with a variation of Dark. And after you’ve selected your template, click the Customize button. Select and customize a template for a new style in Mapbox StudioAnd now we’re dropped into our customization UI. Mapbox customize style UIFrom here, you can really do what you’d like. There are a ton of options to customize your map. It’s a little complex to try to dig in here, but Mapbox provides some resources to try to help you get productive. Generating a Mapbox token Once you’re happy with your new style and everything’s published, we want to generate a token that we’ll use for providing access to our Map. Head on over to the Account section of the Mapbox dashboard. Creating a new token in MapboxMapbox provides you with a “default” token that you can use in your applications. You're free to use this, but I recommend creating a new token that you can provide a unique name, that way if you ever blow past the free tier of Mapbox, you’ll be able to track your usage. Additionally, it’s best to keep a separate token for each application, that way you can easily rotate an individual key, without having to update every application using it. Once you click Create a token, you can set up the key how you’d like, with the scopes and permissions you choose, but for our purposes, you can leave all of the Public scopes checked for our map, which they do by default. Create a new access token in Mapbox Configuring our custom endpoint For this tutorial, we’re going to use Mapbox’s Static Tiles service. Mapbox Static Tiles Maps APIOur endpoint will look like the following: https://api.mapbox.com/styles/v1/{username}/{style_id}/tiles/256/{z}/{x}/{y}@2x?access_token={access_token} There are a few parameters here we need to understand: username: this will be your Mapbox account’s username style_id: this will be the ID of the style you created before z, x, y: these are parameters that Leaflet programmatically swaps out, so we want to leave them as is access_token: this is the Mapbox key you created above To find your username and style ID, we can use the Style URL for our new Mapbox style to get those values. Finding the Style URL in Mapbox StudioIn my example, my Style URL looks like: mapbox://styles/colbyfayock/ck8lryjfq0jdo1ip9ctmuhc6p colbyfayock is my username and ck8lryjfq0jdo1ip9ctmuhc6p is my style ID. And once I update my endpoint parameters, the final tilepoint URL will look like: https://api.mapbox.com/styles/v1/colbyfayock/ck8lryjfq0jdo1ip9ctmuhc6p/tiles/256/{z}/{x}/{y}@2x?access_token=MYACCESSTOKEN Part 2: Adding a custom TileLayer to React Leaflet When building a map with React Leaflet, your main component will be a that wraps the entirety of the app. This is what sets up your Map instance for Leaflet. For our purposes here, we’re going to use the example on the React Leaflet homepage as our starting point. React Leaflet TileLayer Component Inside of your component you include a component, which defines the imagery of the world that you base your map upon. The example on the React Leaflet homepage uses a public version of OpenStreetMap as their TileLayer, which is an open source map project created and updated by people all around the world. This gives you a basic map, but we want to swap in Mapbox so we can set up a custom look and feel for our map. Custom Mapbox TileLayer To add our custom style, we’ll want to update the url and attribution props of the TileLayer component. For URL, it will simply be the custom style endpoint we created earlier, so in my example, it looks like: https://api.mapbox.com/styles/v1/colbyfayock/ck8lryjfq0jdo1ip9ctmuhc6p/tiles/256/{z}/{x}/{y}@2x?access_token=MYACCESSTOKEN For attribution, we want to credit Mapbox as the service, so we want to set our attribution as: Map data © OpenStreetMap contributors, CC-BY-SA, Imagery © Mapbox When plugged in to our TileLayer, our code should now look like this: And once we open up our map, we should see our new basemap! React Leaflet with a Mapbox basemap See the code! If you want to see how I did it, check out the diff commit by commit. The only caveat there is I created an .env.development.local file in the root of my project in which I stored a new environment variable called REACT_APP_MAPBOX_KEY  to store my Mapbox key. Part 3: Adding a custom basemap to Gatsby Starter Leaflet I’ve written a few other articles on how to get started with my Leaflet Gatsby Starter, but for this part, we’ll want to have a basic app spun up that we can use to change our TileLayer endpoint. Setting up our React Leaflet Gatsby app To get started, check out the instructions on the Starter github: https://github.com/colbyfayock/gatsby-starter-leaflet Once you’re ready, you should have a basic mapping app ready to go! New Leaflet Gatsby app in the browser Configuring our Mapbox service The first thing we’ll want to do is add Mapbox as a service in our src/data/map-services.js file. Taking our custom endpoint URL that we created in Part 1, let’s set up a new object with a name of Mapbox, and with a url and attribution similar to what we did in Part 2. export const mapServices = [ { name: ‘OpenStreetMap’, attribution: '©

Creating a custom tile layer with TypeScript

The ArcGIS API for JavaScript provides you with many different layer types that support various data types and visualizations. We also provide you with the building blocks for creating your own custom layer types. These are BaseTileLayer, BaseDynamicLayer, and BaseElevationLayer which were introduced in the 4.4 version of the API.

Custom layers are useful in the following situations:

Display an unsupported data source in your JavaScript application without having to convert it to a data format supported by ArcGIS.

Process the data returned from the service before it is displayed. This could be because the service returns binary data, and the data needs to be processed to generate an image so it can be displayed on the view.

Display synthesized data such as an exaggerated elevation layer.

In this post, we will discuss about creating a custom tile layer in 4.x with TypeScript. Prior to creating custom layers with TypeScript, we need to make certain that we have the needed requirements.

TypeScript: You will need to set up your TypeScript development environment. TypeScript is a strict syntactical superset of JavaScript. Once written, it can be compiled to plain JavaScript. There is a multitude of great online resources that go into detail on what TypeScript is, why it is used, and how you use it.

Familiarity with esri/core/Accessor: Accessor aims to make developing classes easy by providing a mechanism to get, set, and watch properties. Please refer to the Implementing Accessor topic for additional details on how this works and its usage patterns.

Understanding the loadable pattern: If your custom layer requires loadable resources, then you must load all loadable dependencies on the layer. Please see the Understanding the loadable pattern topic for additional details on how this works.

We will walk through how to create a BlendLayer, based on this working sample. This layer will apply multiply blending operation to the ArcGIS World Hillshade and National Geographic World Map services. The multiply blend mode multiplies the values of each pixel of the top layer with the corresponding pixel value of the bottom layer. Multiplying the hillshade tiles with the National Geographic tiles creates a more detailed representation of the terrain than you see from the default National Geographic basemap.

Implement BlendLayer class We will create the BlendLayer class (app/BlendLayer.ts) which will extend BaseTileLayer. You can view or download the source code for the entire application from here. The application has the following folder structure.

root-folder/ index.html package.json tsconfig.json app/ main.ts BlendLayer.ts node_modules/

Add dependency paths and import statements When creating custom classes for ArcGIS API for JavaScript with TypeScript, the following triple-slash references are always added at the top of the class. They instruct the compiler to import AMD modules: __extends and __decorate, which are helpers when extending a class or decorating members of a class.

/// <amd-dependency path="esri/core/tsSupport/declareExtendsHelper" name="__extends" /> /// <amd-dependency path="esri/core/tsSupport/decorateHelper" name="__decorate" />

Next, we will import the modules that will be used in this class as shown below. In the first line, we are importing subclass, declared and property decorators from esri/core/accessorSupport/decorators module. These decorators can be thought of as the underlying glue that is used to create 4.x classes.

import { subclass, property, declared } from "esri/core/accessorSupport/decorators"; import TileLayer = require("esri/layers/TileLayer"); import BaseTileLayer = require("esri/layers/BaseTileLayer");

Extend BaseTileLayer class Here, we are extending the BaseTileLayer class. The @subclass decorator is used in conjunction with declared and is necessary as they are both key components needed for instructing subclasses off of a given base class.

@subclass("esri.layers.BlendLayer") class BlendLayer extends declared(BaseTileLayer) { }

Add properties to BlendLayer class Within this class implementation, we can define properties of the class using @property decorator. We define a property called multiplyLayers, which is an array of tile layers that will be blended together as shown below:

@property() multiplyLayers: TileLayer[] = [];

Add methods to BlendLayer class We can now add public and private methods to the class. The tile layers added to the multiplyLayers property are loadable resources. If a custom tile layer requires loadable resources, then you must load them in the layer using the load() method. This ensures that all loadable resources required for the layer to function are loaded prior to the custom layer resolving and becoming loaded.

load(): any { // call load method on each tile layer stored in multiple property this.multiplyLayers.forEach(function (layer) { // The tile layers must load() prior to the BlendLayer // resolving and moving to the "loaded" status. this.addResolvingPromise(layer.load()); }, this); }

Once the layer is loaded with its required resources, we must override the fetchTile() method of the BlendLayer. Within this method, call fetchTile() on each tile layer returned in the multiplyLayers property. Once each tile layer returns the tile(s) visible in the view, we apply multiply operation to the tiles so that the BlendLayer will show the blended image.

// Fetches the tile(s) visible in the view fetchTile(level: number, row: number, col: number): IPromise<HTMLCanvasElement> { const tilePromises = this.multiplyLayers.map(layer => { // calls fetchTile() on the tile layers returned in multiplyLayers property // for the tiles visible in the view return layer.fetchTile(level, row, col, { allowImageDataAccess: true }); }); return all(tilePromises) .then(images => { // create a canvas let width = this.tileInfo.size[0]; let height = this.tileInfo.size[0]; let canvas = document.createElement("canvas"); let context = canvas.getContext("2d"); canvas.width = width; canvas.height = height; // multiply - multiplies the numbers for each pixel of the top layer (nat geo) // with the corresponding pixel for the bottom layer (hillshade). context.globalCompositeOperation = "multiply"; images.forEach(function (image) { context.drawImage(image, 0, 0, width, height); }); return canvas; }); }

Finally, we export the BlendLayer class. The export = syntax specifies a single object that is exported from the class so that the class can imported using import module = require(“Class”) elsewhere.

export = BlendLayer;

We are done implementing the BlendLayer class. Now let’s use this custom layer in an application. We will import the class in in the app/main.ts file as shown below:

import BlendLayer = require("app/BlendLayer")

Now the BlendLayer can be used in the application.

const natGeoLayer = new TileLayer({ url: "http://ift.tt/2gP3yny" }); const hillShadeLayer = new TileLayer({ url: "http://ift.tt/2ifhiZd" }); // Create a new instance of BlendLayer const blendLayer = new BlendLayer({ multiplyLayers: [ hillShadeLayer, natGeoLayer ], title: "Blended NatGeo World Map", copyright: "Blended National Geographic Layer" });
