Differences between Total.js v5 and Total.js v4

This blog post describes the main differences between Total.js v4 and Total.js v5. Total.js v5 contains almost new and nicely written code. This blog post will be gradually updated.



What is new in Total.js v5?

Only shorter, cleaner and improved code. Finally, the repository contains much nicer code. It’s fully optimised for Node >18.

Should I update the Total.js v4 apps?

No. We started testing Total.js v5. You can develop upcoming projects with Total.js v5. For stability reasons, wait before converting older apps to Total.js v5.

Is the Total.js v5 stable?

Almost yes. We use Total.js v5 in several projects, and they work without critical issues. We are working on unit-tests, documentation, etc..

How can I determine Total.js v5 in the code?

Internal session mechanism

The SESSION() method is removed in Total.js v5. The workaround is to use the AUTH() method with predefined session functionality. More information at the link below:
