Idea I have for implementing parts of a bash script in node.
Write a dictionary of JavaScript functions in a JS script. Use bash's coprocess feature to launch a node process as a slave to the bash process. node process sends a string of bash source code that stubs out bash functions, one for every JavaScript function.
When the bash function is invoked, it encodes and sends its arguments to the node process. The node process runs the JS function, encoding and returning the result to bash.
When bash terminates, coprocess pipe is closed, node process kills itself.

that exports a dictionary of
functions.
Put this snippet at the top of your bash script:
eval "$( bash-node-ipc bootstrap $__dirname/node-fns.js node_coproc )"
This will launch the node coprocess and declare a bash function corresponding to each exported node function. You can now call node functions from bash, and they'll run within the node coprocess.
For a slight improvement in startup time, inline the bootstrapper directly into your bash script:
bash-node-ipc $__dirname/node-fns.js node_coproc >> ./my-bash-script

?After running the example, bash is in a weird state where arrow keys spit out ANSI instead of interacting with readline. Why is this? FIXED
