进程在节点REPL上运行

Question

I would like to run a process on top of node REPL. The objective here is to allow users to use the node REPL the way they would by simply typing a command into their terminals, but to load some modules automatically into that REPL.

The solution to this problem would be best if somehow the stdin was piped back and forth to the REPL running in the background, but also satisfactory if the REPL simply had some modules loaded into it prior to allowing the user to inout stdin.

What I could do would be to work with process.stdin.resume() to allow users to input commands, evaluate them, and process them inside of the already running node process, but this is duplicating functionality of the already existing node REPL.

Is there any way to do this? Does child_process have a medium for this kind of control?

Any proposed solution can also use es6. Thanks in advance.

EDIT: Please let me know what I can do to improve this question as it has been viewed several times, but not touched. I cannot provide an example because I do not know how I would go about doing something like this.

Answer 1

Have you seen the built in repl module?

https://nodejs.org/api/repl.html

It looks like it covers everything you want to do.

If you want a custom context, you would probably need to pass a custom eval function. The node documentation has examples.
