node-modbus

Intro

Use TypeScript Implement Modbus TCP/RTU Client/Server Library

Background

node-modbus-serial

is probably the most complete and easy-to-use Modbus package in the existing community. I have also contributed to this community, but there are still many issues, such as:

• Incomplete TS type definitions
  • This largely prevents developers from using editor autocompletion or type checking.
  • Although it has Modbus TCP/RTU Client/Server functionality, the lack of documentation and unclear types means that developers need to look at the source code to use it.
• The underlying implementation is too bloated to fully utilize V8's performance.
  • Many meaningless prototype chain modifications.
  • A large number of new objects, which can be inferred to cause GC/OOM/performance issues in certain situations.

For this reason, I plan to redevelop the Modbus-related package.

If successful, I may consider donating the copyright to the community or foundation...etc.

Current Status

• [x] Modbus TCP Client
• [x] Modbus TCP Server
• [x] Modbus RTU Client
• [x] Modbus RTU Server
• [x] Debugger
• [x] CI/CD
• [x] Document

Currently, the main focus is on type declaration. Due to my busy work schedule, updates may be irregular. Collaboration is welcome.
