CP-Node

This repository contains the files to run CodeParadise applications within Node.js.

Just clone this repo or copy the individual files to a directory and you're good to go. It's that simple. Well...almost. Don't forget to install CodeParadise and have it running.

Run the following command to startup the example (calculating HTTP Server):

APP="http-server-example" SERVER_URL="ws://localhost:8080/io" node cp-node.js client-environment.image

The above command will run the CodeParadise application "http-server-example" within Node.js. It is a calculating HTTP Server. You can send urls like http://localhost:8181/add:42 or http://localhost:8181/multiply:3.14 to it or combine them http://localhost:8181/subtract:7/add:3. The server will perform the calculations and keep track of the current value. To see the calculations and value send http://localhost:8181/value. You can also http://localhost:8181/undo or http://localhost:8181/reset the calculations.

Finally, you can 'snapshot' the image and restart it later. The current application (in this case server) state is kept. So any calculations present are stored in the image. To snapshot use the url http://localhost:8181/snapshot. Snapshotting means the Smalltalk image gets 'sealed', it will no longer be connected to the CodeParadise server. Updates to the code will not be propagated to the image. Once sealed it can be run without needing the CodeParadise server running, so you can distribute the application to your friends ;-). To start you can simply use node cp-node.js client-environment.image without supplying the server information. You can change the name of the image file to better match your application's name of course.

There are two bundles, both are actually minified but the .min version has name mangling turned on which might make debugging a little more difficult.

Bun

Bun is a drop-in replacement for Node.js. Bun can be used with CP-Node, but is not heavily tested.

Happy hacking!
