Baapan

Baapan brings the all of the NPM goodness right into your REPL. On-the-fly!!.

Using Node REPL for quick local testing is a common practice among JavaScript/Node developers. But the problem with the REPL is, you don't have the luxury to take advantage of the entire NPM ecosystem out-of-the-box.

An alternative is, using something like RunKit. But fiddling with sensitive data in an online tool is not the best choice for many developers.

While using Node REPL, if you feel you need an NPM module to quickly test something (e.g, lodash to do some quick object/array manipulation, uuid to quickly generate some uuid), you'll have to manually install it via NPM and load it onto the REPL. Here's how baapan makes it easy!!!

Baapan - the life saver

Baapan intercepts require() calls and automatically install the module if the module is not locally available. You can require() whatever you want, and Baapan will require() it for you? Don't you think it's cool??

Getting Started

Step 1: Install baapan globally

Simply run:

npm install -g baapan

This will install baapan CLI command.

Step 2: Load Baapan

You can launch Baapan by just running baapan command on terminal after installation. baapan will launch the NodeJS REPL for you.

$ baapan

That's it. You can now require() everything you want!!

This time I need to generate a random IP address. I can require chance to do that.

Workspace loaded!
> const chance = require('chance').Chance()
undefined
> chance.ip()

Baapan Workspace

Every instance of baapan REPL server has its own workspace independent of each other. All module installations are done within the boundary of the workspace. This helps you open multiple baapan REPLs at once, install different modules without any conflicts. Current workspace for the REPL is automatically cleaned-up when you gracefully exit the REPL shell (e.g, pressing ctrl+c twice or .exit command).

Note! If the REPL process was killed forcefully, the workspace directory will not be cleaned up automatically. You have to clean up these stale workspace directories manually.

Workspaces are by-default created in $HOME/.baapan/ directory. You can see the workspace directory for your REPL session by reading the BAAPAN_WS_PATH environment variable.

e.g,

> process.env.BAAPAN_WS_PATH
'/Users/djayasekara/.baapan/workspace_44023_1562678000424'
