Lab Info
Lab exercises in this course are designed to work either on native hardware, or using a virtual machine (VM), under a hypervisor, such as those in the KVM, VMWare, or Virtual Box families. Detailed instructions to set up your lab environment are provided in the course.
If using a cloud provider like GCP or AWS, you should be able to complete the lab exercises using the free tier or credits provided to you. However, you may incur charges if you exceed the credits initially allocated by the cloud provider, or if the cloud provider’s terms and conditions change.

Exam Details & Resources
This exam is an online, proctored, performance-based test that requires implementing multiple solutions within a Remote Desktop Linux environment. Visual Studio Code, Vim and Webstorm (kindly sponsored by JetBrains) are included as editors in this environment.
The exam includes tasks simulating on-the-job scenarios, and Candidates have 2 hours to complete the tasks.
 

Objectives

This course provides core skills for effectively harnessing a broad range of Node.js capabilities at depth, equipping you with rigorous skills and knowledge to build any kind of Node.js application or library. While by design the training content covers everything but HTTP and web frameworks, the crucial fundamentals presented prepares the student to work with web applications along with all types of Node.js applications. This includes command line tools, real-time applications, network applications, desktop applications, build tools and more. By taking this course, students will be fully prepared for the OpenJS Node.js Application Developer Certification (JSNSD) and acquire pragmatic knowledge and core skills that accelerate both Node.js productivity and career growth.
 

Audience

This course is for those starting out in web application development who want to gain more practical skills and improve their abilities. The course is also useful for web application developers preparing for the JSNAD certification exam. Only a basic knowledge of the command line is required.
