Question: can geth and web3.js APIs be accessed with ijavascript? #176

I have a question.

Can ijavascript be used for bringing up and working with a geth ethereum console which is based on npm?

IJavascript runs Javascript inside a Node.js session. So the answer to your question is yes, it is.

IJavascript is able to require npm packages. You need to make sure that they've been installed and that require can find their location. This depends on your setup.

Here's a quick&dirty way to do it:

$ mkdir myproject
$ cd myproject
$ mkdir node_modules
$ npm i web3 geth
$ ijsnotebook

The key idea is that you need to ensure require can find the location where web3 and geth have been installed.

Most frontends set the working directory to the same folder where your notebook file is.

IJavascript also provides the flag --working-dir=path to set the working directory (see here).
