code-pump 

Live develop your nodejs app and inspect its state, from a nodejs-workspace in
Lively Web!

nodejs code injection, extraction, and evaluation. Can evaluate in the context
of modules by using lively.vm.

Also supports nodejs process creation for "workspace processes". Controlled
either directly via the evaluator / process interfaces or via websockets. Ws
server is part of the package.

Usage

$3

1. npm install code-pump --save-dev
2. PATH=$(npm bin):$PATH code-pump localhost:9004
3. In Lively, open a nodejs-workspace, click on the red "disconnected" button,
and enter ws://localhost:9004

$3

``js
require("code-pump").start("localhost", 9004, err =>
console.log(err ? "Code pump error:" + err : "code-pump started!"););
`

Then connect as in 3. above.

API

$3

Given a file some-module.js in the base directory of your app that includes

`js
var internalState = {of: {module: 23}};
`

you can access it via

`js
var e = require("code-pump").evaluator;
e.evalIn("./some-module", "internalState.of.module"); // => 23
`

$3

`js
var p = require("code-pump").process;
p.startNodejsWorkspace({}, (err, procMgr) => {
procMgr.sendToChild("eval", {code: "1+2"}, (err, answer) {
console.log(answer.data.value); // => 3
});
});
`

$3

If you want your own client then setup a server like above

`js
require("code-pump").start("localhost", 9004, err =>
console.log(err ? "Code pump error:" + err : "code-pump started!"););
`

In your client (nodejs or browser) run

`js
var ws = new WebSocketClient("ws://localhost:9004/");
ws.send(JSON.stringify({
action: "eval",
data: {module: "./some-module", code: '3 + 4 + internalState.of.module'}
}));
ws.onmessage(function(e) {
JSON.parse(e.data).data.value; // => 30
});
``
