 - [Helux-nextjs-starter](https://github.com/heluxjs/helux-nextjs-starter)
 
 It has the following features:
+
 - Developed based on the fastest immutable js library [limu](https://github.com/tnfe/limu), with super performance
 - Atom supports dependency collection, which means that atom does not need to be split into details. Atom can be equivalent to model, which is naturally friendly to `DDD` domain-driven design.
 - Built-in signal response mechanism, which can achieve 0 hook encoding + DOM granular update
