Learn Neo4j, Nwjs and Tachyons

In this course we will learn some of the basics of getting data into and out of Neo4J, as well as touch on some of the libraries and tooling available in the Neo4J community ecosystem, which we will leverage to quickly create and use a full-featured GraphQL API.

We will start by learning how to run and interact with Neo4J locally. Then we will develop a graph model in which to store the data that we pull from SWAPI via REST. We will then create an Apollo GraphQL API driven by a few simple schemas which fit into this model. We will then write some simple code to crawl SWAPI and insert the data into Neo4J through our GraphQL API. Once there is data in the store, we will learn about some of the features in `neo4j-graphql-js` that make connecting and accessing our graph Nodes easier.

Neo4j delivers the lightning-fast read and write performance you need. Neo4j combines native graph storage, scalable architecture optimized for speed, and ACID compliance to ensure predictability of relationship-based queries.

NW.js is an app runtime based on `Chromium` and `node.js`. You can write native apps in HTML and JavaScript with NW.js. It also lets you call Node.js modules directly from the DOM and enables a new way of writing native applications with all Web technologies.

Let's add some module loading to our NW.js. Webpack and dependency management FTW!

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

You can easily add CSS libraries to Nuxt using `yarn` or `npm` to install them, then simply adding them to the `nuxt.config.js` so they're included in each page. Then all the classes will be available for use in all of your templates. This lesson walks your through installing a library then adding it to your `nuxt.config.js`.

Tachyons provides extensions (-ns, -m, and -l) to many of its classes to help you design for responsive layouts. This lesson walks you through designing for mobile first then adding a design for desktop.

Design for Mobile First with Tachyons

Building responsive css layouts is critical in any modern website. Tachyons makes this easy by designing for mobile first then enabling you to switch directions and positions of elements when the site scales up to desktop sizes. This lesson walks you through using Tachyons with flexbox and leveraging the `flex-column` and `flex-row` classes to respond to mobile and desktop sizes.

There are different types of data in Neo4J: Nodes and Relationships. We will cover the ways to create each type of data: creating nodes with properties, creating nodes with relationships, and creating constraints on nodes and relationships.

Create Nodes and Relationships in Neo4J with Cypher

Once there is data in Neo4J, we need to be able to access it. We will cover the structure of a cypher query to return parts of our graph.

Read Nodes and Relationships in Neo4J with Cypher

The data in our graph is unlikely to stay the same forever. We will cover the syntax used to find and modify existing data in different ways through the use of parameters.

Update Nodes and Relationships in Neo4J with Cypher

Nothing lives forever, so we need to know how to use DELETE and DETACH to get rid of nodes and relationships we no longer want in our graph.

We will learn about `neo4j-graphql-js` and how to leverage it to quickly create a full-featured API backed by Neo4J. We will create a few simple schemas to represent our model.

Use neo4j-graphql-js to Create a Simple API

We will learn to use the `@relation` directive provided by `neo4j-graphql-js` to make the relationships in our model explicit in our schemas.

Explicitly Model Schema Relationships with the @relation Directive in neo4j-graphql-js

We will use automatically generated mutations in a Apollo GraphQL API augmented with `neo4j-graphql-js` to insert data that we get from SWAPI into Neo4J.

Create Data in Neo4J Through a GraphQL API

We will use the `@cypher` directive provided by `neo4j-graphql-js` to return data about how nodes are related to each other in our schemas without writing custom resolvers.


Build Complex Schema Relationships with the @cypher Directive in neo4j-graphql-js

We will use our own custom mutations in an Apollo GraphQL API to update or create data that we scrape from SWAPI into Neo4J with. We will use the `@cypher` directive to use custom merge statements in these mutations.
