You didn't answer my question. How to access the data in the stream?
The big advantage of Pascal streams is the ability to easily read/write
any datatype. This is not possible in JS.
What kind of alternative overloads do you plan?

And reading/writing for example a word is fast in Pascal. I guess it
will be a lot slower in JS.
NodeJS has streams. They support writing strings/buffer/uint8array and
strings support encoding. So the NodeJS implementation is easier than
the browser implementation.
I started the nodejs external classes in unit nodejsfs. Feel free to
complete the external classes. Note that nodejsfs is currently a mix
up of streaming classes, filesystem class and Pascal RTL functions like
FileExists. It is planned to distribute these parts to multiple units.
