Learn 11ty, Leaflet and Particle

If you've ever worked on a website for a business, there's a good chance you've included a map.

A Google Map embed is sufficient for showing a location, but doesn't leave you many customization options.

React Leaflet to the rescue!

In this course, Colby Fayock will guide you through a series of lessons and challenges that will build your map making skills as you build out a web app for a fictional restaurant.

You'll get practice with handling API keys and using React Hooks to implement a custom interactive map complete with metadata and additional overlays.

This course has built-in challenges that you are encouraged to pause and work through, but feel free to just watch.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Build Maps with React Leaflet

In this collection, you'll learn the basics of creating a new map in your React application with React Leaflet. We'll walk through adding the map itself as well as adding markers with popups, different shapes, and increasingly complex features to your map!

Mapping with React Leaflet

Eleventy, or 11ty,  is a simple yet very powerful static site generator. It does not require any config to get started.

This what it will take you to get an 11ty project running.

```
npm install -g @11ty/eleventy
echo '# Page header' > README.md
eleventy
```

After watching this collection you will be able to:

* Bootstrap a simple 11ty website
* Use 11ty layouts
* Chaining multiple 11ty layouts
* Use 11ty Collections
* Create pages from data

...and much more

Eleventy was created to be a JavaScript alternative to Jekyll. It’s zero-config by default but has flexible configuration options. Eleventy works with your project’s existing directory structure.

Eleventy uses independent template engines. We don’t want to hold your content hostage. If you decide to use something else later, having your content decoupled in this way will make migration easier.

Getting Started with Eleventy

Start from a blank project and build up to an Eleventy site that includes a blog collection and is prepared to source content from a headless CMS. You'll also learn how to add Sass as the styling solution, complete with triggering 11ty to re-compile when the Sass changes.

These lessons will help explain key 11ty features and concepts to help you make the most of this amazing static site generator.

By the last lesson, you'll have learned how to:
- define custom `input` and `output` directories
- create a layout that accesses front matter variables
- watch for Sass changes and include CSS in the build proces
- create an 11ty collection using `tags`
- define front matter for an entire collection
- make and apply a filter to a collection
- generate pages from an external data source, such as a CMS or API

Build An Eleventy (11ty) Site From Scratch

In this video, you will learn to bootstrap an eleventy project.

we'll start from an empty directory, initialize it as an npm package, install `@11ty/eleventy` package and create the website entry point.

Eleventy can compile multiple file formats, HTML, markdown, liquid, and njk.

Check out the eleventy [docs](https://www.11ty.dev/docs/) for more information.

Bootstrap an eleventy project

In this video, you will learn how to use the eleventy layouts feature.
Eleventy Layouts are special templates that can be used to wrap other content.


for more information check the layouts [docs](https://www.11ty.dev/docs/layouts/)

Use eleventy layouts

In this video, you will learn how to use layout chaining with eleventy.
Layouts in eleventy can use other layouts. You can also use a different template engine across layouts. This is very handy if we want to wrap some pages with extra markup but not all the pages.

Use Layout Chaining in eleventy

In this video, you will learn how to create pages from data in eleventy. a data source can be a JSON file or a js file.

Create pages from data in eleventy

In this video, you will learn how to use the collection feature in eleventy.
Collections will allow to group content under one tag and loop through it in your template files

Use Collections in eleventy

In this lesson, you will learn how to add a map to your React application using React Leaflet. We will walk through importing and configuring the Map and TileLayer components from React Leaflet to set up the new map.

Create a New Map using React Leaflet

In this lesson, you will learn how to add a Marker and Popup component to a Map when using React Leaflet. We'll walk you through importing the components and adding each one to the Map. Additionally, we'll resolve an issue with loading marker images that's inherent to creating a new React Leaflet map in Create React App, which we'll fix by manually importing the image from Leaflet and configuring those images to the marker.

Add a React Leaflet Marker with a Popup to a Map

In this lesson, you will learn how to add the Polygon and Circle shape components to a Map when using React Leaflet. We'll walk you through importing both components, adding each component to the Map, and setting a unique color for each shape.

Add Shapes to a Map in React Leaflet

In this lesson, you'll learn how to style shapes on your map to change the look and feel using React Leaflet's API. We'll use React component props like color and weight on our shapes to change the colors and styles.

Style React Leaflet Shapes using Component Props

In this lesson, you'll learn how to use CSS to style and animate shapes on your React Leaflet map. We'll use the className prop to add a custom class and add CSS to customize our shapes.

Style and Animate a React Leaflet Shape with Custom CSS

In this lesson, you will learn how to use React hooks to interface with the Leaflet Map API in React Leaflet. We'll connect a ref to our Map component using the useRef hook and then use the useEffect hook to access that ref, find our Map instance, and use it to fly to a new location.

[More details on the Leaflet Map API](https://leafletjs.com/reference-1.6.0.html#map)

Interface with the React Leaflet Map API with the useRef and useEffect React Hooks

In this lesson, you learn how to use the React Leaflet ZoomControl component to add a custom zoom control to your map. We'll walk through removing the default control to avoid duplicates, using the ZoomControl position prop to change its location, and setting custom icons with the zoomInText and zoomOutText props.

Change the React Leaflet Map ZoomControl Location and Icons

In this lesson, you will learn how to add GeoJSON data to a map in React Leaflet. Using the National Parks in the United States, we'll import a GeoJSON document, create a new Leaflet GeoJSON instance, and add a marker with a popup for each park.

[Parks Locations Example](https://www.nps.gov/maps/tools/npmap.js/examples/geojson-layer/)
[Parks GeoJSON](https://www.nps.gov/lib/npmap.js/4.0.0/examples/data/national-parks.geojson)

Add GeoJSON Location Data to a Map Using Markers and Popups in React Leaflet

In this lesson, we'll add a new tile service as our basemap in React Leaflet. Using the NASA GIBS Blue Marble, we'll update the TileLayer component's url and attribution props to the new service. We'll also add the maxNativeZoom prop which allows us to configure the maximum zoom allowable for the service.

Change the Map Tile Service of a React Leaflet TileLayer Basemap to NASA GIBS Blue Marble

In this lesson, we'll add a LayersControl toggle to allow us to change between multiple TileLayer basemaps in React Leaflet. Using the NASA GIBS Blue Marble, we'll add an additional TileLayer component, wrap our two TileLayers in BaseLayer components, and wrap all of our layers in a LayersControl to toggle our basemaps.

Add a LayersControl Toggle to Switch Between TileLayer Basemaps in React Leaflet

In this lesson, we'll use the LayerGroup and FeatureGroup components to organize feature shapes on our map. Using these grouping features, we'll learn how the LayerGroup is used for organizational purposes like adding or removing multiple layers at once and how we can update the color of all of our grouped shapes with the color prop on our FeatureGroup.

Manage Map Data and Feature Shapes Together in a React Leaflet LayerGroup or FeatureGroup

In this lesson, we'll use an image to create a custom map marker icon for GeoJSON location data on our map. We'll walk through importing a custom image, creating a new Leaflet Icon and Marker instance, and use them to customize our National Parks markers.
