You can install Unison on the Mac via homebrew (brew install unison), but it's very likely that it won't work properly, resulting in errors like:

How to Use macOS Finder as a MacVim File Drawer

When I switched to Vim from TextMate 2, the feature I missed the most was a decent file drawer (no, NERDTree doesn't cut it). I'm happy with [fzf.vim][fzf], but having the project tree in front of you can be really useful from time to time, e.g. when working with unfamiliar codebase, a new project etc.

Encrypted Tokens Between Rails and Node

If you need to pass data safely between Rails and Node, you can use the built-in Rails encryption.

The script below wraps ActiveSupport::MessageEncryptor, allowing to create expiring JSON tokens that can be decoded in Node using a shared secret.

secret = "866b914a169d3969849966febafe8057bec6b82ea477e64682a11a2e61096797"
payload = { user_id: 1, name: "John Doe", role: "admin" }
EncryptedToken.encode(payload: payload, expires_at: 10.minutes.from_now, secret: secret)
