Learn 11ty, Elasticsearch and Radium

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

In this course, you will learn the basics of using Elasticsearch within your application. You will learn how to store and retrieve data in Elasticsearch as well as how to leverage its powerful search features.
 
You will be able to design indices, types and maps for your application to leverage the most from Elasticsearch and you will learn how to monitor the health and performance of your Elasticsearch servers to identify and resolve capacity issues before they impact your application.

Throughout this course, we will be using the [Simpsons dataset](https://www.kaggle.com/wcukierski/the-simpsons-by-the-data) containing all of the Simpsons episodes, characters, and lines. It will be the foundation for learning to retrieve data from Elasticsearch, perform complex searches, and understand and implement best practices for storing data in Elasticsearch.

Get Started with Elasticsearch

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.


for more information check out the eleventy [docs](https://www.11ty.dev/docs/layout-chaining/)

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.

for more information check out the eleventy [docs](https://www.11ty.dev/docs/pages-from-data/)

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

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

Use Collections in eleventy

Begining from a brand new project, learn how to install Eleventy (11ty), and add `develop` and `build` scripts. Next, define a custom configuration to set preferred input and output directories. Then create a home page file and your first layout while learning how 11ty handles mixing templating languages.

Create an Eleventy (11ty) Site From Scratch

Learn how to add Sass to an Eleventy (11ty) project including directing 11ty to re-compile when Sass changes are made. This step involves adding two new functions to the `.eleventy.js` configuration: `addWatchTarget()` and `addPassthroughCopy()`. Then, define the link to the compiled CSS file within an 11ty layout.

Add Sass Compiling and Watch for Changes in Eleventy (11ty)

Create a blog directory with posts for your Eleventy (11ty) project, and learn how to define the posts as an 11ty collection using `tags`. Then make a blog index page and write a `for` loop with Nunjucks to output a list of each post linked to the post page.

Define an Eleventy (11ty) Collection to Create a Blog

Filters in Eleventy (11ty) are a way to mutate data including string variables or arrays such as collections. Learn to create a filter for use on a collection which will select a random item from the collection.

Apply a Filter to an Eleventy (11ty) Collection

Eleventy (11ty) is able to run any JavaScript or Node functions at build time. This makes it possible to source external data such as from a headless CMS or other API. Learn how to generate pages from data pulled from a mock CMS using the 11ty `pagination` method and designate the data as an 11ty collection. You'll also learn how to define variables for the page using `eleventyComputed`, and then write a `for` loop to output a link to each page.

Generate Eleventy (11ty) Pages From External Data

Closing and opening indices on Elasticsearch allow you to free up resources in your cluster when they aren’t needed, preventing you from scaling or growing your cluster to support unused indices. In this lesson, you will see how easy it is to do both and learn to do so on your own indices.

Close and open an Elasticsearch index

In this lesson, you will learn how to add new documents to the Elasticsearch data store using HTTP methods and the Elasticsearch API. You will also learn how Elasticsearch uniquely identifies each document and what happens when you attempt to create a document that already exists.

Add data to Elasticsearch

Elasticsearch provides several methods for using its powerful search features. In this lesson, you will be introduced to the `_search` endpoint, the datapoints returned in results, how to set a query timeout (and what a timeout *doesn’t* do), and how to search specific indices and types.

Search for data in Elasticsearch using the _search endpoint

Elasticsearch provides a powerful API over http for accessing its features. In this lesson, you will be introduced to the API and learn how to use it to get data from Elasticsearch using the browser and the popular command curl.
We will see how adding  query stream parameters can exclude or include the properties that we desire from our data.

Setup is specified in the `README.md` of the repository linked below.

Get data from Elasticsearch by id using http

By default, search results are limited to the top 10 results. In this lesson, you will learn how to change the pagination size, paginate through results, and you will learn about the performance implications of pagination on Elasticsearch.

Paginate through search results in Elasticsearch

Elasticsearch offers two API endpoints for updating documents. In this lesson you will learn how to use those endpoints to replace entire documents in the store and update partial information within a document.

Update data in Elasticsearch

Elasticsearch provides a full featured client for nodejs available via npm. In this lesson, you will learn to how install the client and use it to retrieve data from your Elasticsearch server.
We will walk through retrieving data through callbacks as well as using promises.

Get data from Elasticsearch by id using the Elasticsearch npm client

Simple searches can be done using query parameters, also known as “Search Lite” by Elasticsearch. You will learn how to perform query parameter searches in this lesson and also discover the upper limits of its usability in this lesson.
