Node development in TypeScript
Content length: approx.
Share code and development s∑kills across your TypeScript front end and Node-based server implementation We've been doing this for years, and will teach your team best practices for quality and productivity.
We use and recommend TypeScript for all JavaScript and Node development. TypeScript reduces defects found in production, making it more and more popular to use in the JavaScript development ecosystem.
This class introduces Node, TypeScript, and several of the most relevant libraries used for development. We focus on API endpoint server, data management, and integration across the stack.
Class topics include:
- Node (and TypeScript) tradeoffs versus other server platforms
- REST/JSON services
- GraphQL introduction
- Data push / streaming
- Built-in and advanced libraries
- Dealing with asynchrony
- Migrating to Node
- Development tooling
- Deployment
- Sharing code between Node servers and web UI
- Security
- Cloud deployment
- Node ecosystem
- Realistic examples
- Hands-on workshops
Students go beyond typical introductory Node instruction to gain a familiarity with the overall ecosystem of high productivity, advanced tooling, and serious Node development.
The class outline contains introductions to important and useful Node technology; but we can customize the class length for customers who have already narrowed their technology choices.
Proven results
We've trained thousands of developers at companies like yoursWho Should Attend?
- Architects, decision makers, and project leaders considering NodeJS for future projects
- Developers slated to create API servers or other back-end systems using Node
- Developers already working in Node, eager to expand their understanding
- Teams which can benefit from "isomorphic" code sharing and skill sharing across tiers
- Developers new to Node, coming from other popular back-end platforms like Java or C#.
You must be familiar with:
- Software development (any language).
- VSCode (free download) to work on TypeScript source code.

Meet your instructors
Your instructors will depend on your custom requests, availability, consulting needs, etc.
Private group classes
For corporate groups and other organizations, we offer live in-person or online events. Our instructors adapt the agenda to match your needs. We can include consulting assistance, or combine topics into a longer workshop week.
Training FAQs
- Q: Is this taught in person?
- A: We offer training both in-person and online via remote conferencing.
- Q: How does the remote option work?
- A: Much like an in-person class, it's conducted by our expert instructors in real time. The instructors answer questions, assist students, etc. We strive to offer as much of the in-person experience as possible, online.
- Q: Can the content be customized?
- A: For private team classes, we *always discuss your goals, the class contents, any specials areas for extra coverage, etc. in advance. We customize both the contents and length (number of days) to your needs.
- Q: Can we schedule a private class any time?
- A: Our classes are taught by developers who use the subject technologies in their daily work, so we carefully assign the right developer/trainer to your class, for a good experience and knowledge match. Please contact us to arrange a date.
