To prevent 40MB downloads for a REPL, is there a library version of Electron that can be installed globally, so that small scripts can use it to produce full applications?

(My expected response is that Electron and Node are both moving fast enough so that multiple versions may be incompatible. Global libraries tend to work for stable software, so it may be possible in the future for Electron.)

That would be great.

Why do you need to prevent 40MB downloads?

I'll look into that :-) Version 2 will be released in three days(Nov 2).

If every package was 40 MB on my computer, my distribution would be 30 GB.

More importantly, these 40 MB of code and resources expand to about 400 MB in memory when the application is running, but a global library wouldn't fix that.

Would

    npm install -g electron-prebuilt

do the trick for users, while they use a smaller version of your release without Electron included?

400MB of RAM for a REPL!? That's absurdly high.

Well, rather than commenting on download size I'll talk about the program.

This looks really awesome! I've been wanting a nice js repl for a while and this one definitely has a lot of the qualities I was looking for.

Auto complete is very nice. Color syntax looks great. The biggest thing I would like to see is to persist history. I'd love to up arrow through previous sessions.

Overall nicely done!

I was just looking for something like this. How do I load external node modules into the repl? I tried "File->Add module path" but it didn't seem to work for me. Basically, having done an npm install of lodash somewhere, I want to do

  var _ = require('lodash');

in the repl.
