Every quarter we share the exciting new courses, additions, and changes in GraphAcademy to keep you informed about new and better ways to learn all about making use of graphs in your work.
The last few months of 2022 were busy for us as we prepared for NODES 2022, but we’ve still got some exciting updates for you.
Sandbox Issues Resolved
We are aware that a number of users have experienced problems connecting to Neo4j Sandbox while attempting challenges in GraphAcademy.
We’re pleased to say that after some investigation, we have managed to identify and solve the problem.
If you are still experiencing problems with the integrated Sandbox window in GraphAcademy, you can also find the Sandbox credentials on the right hand side of the course overview page. Clicking on the Sandbox URL will take you to Neo4j Browser.
You can also access the Sandbox instance by logging into sandbox.neo4j.com with your GraphAcademy user credentials.
If you are still experiencing problems, please feel free to reach out to us at firstname.lastname@example.org.
If you don’t have time to complete every challenge but would still like to earn your badge, you can now take a Lightning Quiz to test your understanding and pass the course.
If you enrolled more than seven days ago, you will be able to access the Lightning Quiz from the course overview page by clicking the Start Quiz button. If you get 100% of the answers correct, you will pass the course!
New GraphAcademy Course: Building Neo4j Applications with Typescript
We are pleased to announce our new Building Neo4j Applications with Typescript course.
The course, estimated at two hours, is shorter than the other courses in the Developer learning path, featuring only three succinct code challenges designed to teach you everything you need to know without being overly repetitive.
The Creating a Driver lesson challenges you to write the code to create a Neo4j Driver instance and use that instance to find the director of a movie in the graph, while to pass the Writing Data to Neo4j lesson you must add yourself as an actor in The Matrix.
All code challenges take place using a service called Gitpod, allowing you to run and complete the tests in your browser without installing any code (Gitpod is a hosted cloud version of VS Code).
In this course you will learn:
- The lifecycle of the Neo4j Driver and how it relates to your application
- How to execute Read and Write Transactions
- How to define TypeScript types and interfaces to add type checking to your TypeScript code
Updated GraphAcademy Course: Building Neo4j Applications with Node.js
As with the new TypeScript course, the Node.js course has been updated to run in Gitpod. This means that you don’t have to clone the repository in order to complete the course. Everything can be done online directly from your internet browser.
Path Finding Algorithms with Neo4j Graph Data Science
The Path Finding with GDS course, released in October, teaches you the various methods available for finding the shortest paths between pairs of nodes in your Neo4j graph and includes examples for both weighted and unweighted relationships.
The course is the first in a series of applied courses for data scientists interested in improving their machine learning algorithms using graph features.
In this one-hour course, you will learn:
- The difference between weighted and unweighted relationships
- How to use Cypher to find the shortest paths between a pair of nodes
- How to use the Neo4j Graph Data Science library to find weighted shortest paths
Your Path to Neo4j Certification
If you have not done so already, consider becoming a Neo4j Certified Professional.
To become certified, you enroll in the Neo4j Certified Professional exam.
We recommend that you take these courses to prepare for certification:
Note that we have a limit of one t-shirt per certification so if you certified prior to 2023 and already received a t-shirt, you cannot receive another one.
NODES 2022 Videos
We hope that you were able to attend our most recent online conference, NODES 2022.
This conference had over 100 speakers from all over the world.
Some of our favorites include:
