PromisePipe is a library that allows building chains of asynchronous transformations and calling business logic functions directly on the server rather than converting data to HTTP requests. It makes business logic look like a Promise by returning a Promise from functions wrapped with PromisePipe(). This allows defining reusable chains that can be cached and passed through "connectors" to integrate business logic on clients and servers.

1. PromisePipe
inception

2. business logic
with
PromisePipe()

3. looks like a Promise

4. is a function

5. that returns a Promise

6. you just build a chain of
transformations

7. and use them multiple times

8. chains could be async

9. the core API is lean

10. but you can extend it

11. and build your own domain
specific API for business logic

12. what conventional APIs do
• convert the data into the combination of HTTP
method, API URL and body.
• make an HTTP request
• catch the request on server side
• try to decode the combination of method, API URL
and body into original data and function to call.
• call the business logic function with the data.

13. what you actually want to do
• call the business logic function with the data on
server.

14. business logic
on client on server

15. business logic
on client on server

16. business logic

17. business logic

18. business logic

20. Connectors

21. connect PP stream to
connector

22. pass files through
connectors

23. cache chains with
PromisePipes
