Hover Preview

Hover your mouse over any process.env.KEY or import.meta.env.KEY reference in your source code to see a tooltip showing the variable's current value from your active .env file.

What the Tooltip Shows​

ENV Manager
KEY: DATABASE_URL
Value: postgres://localhost/mydb
File: .env

For keys that look like secrets (containing TOKEN, SECRET, KEY, PASS, PWD), the value is partially masked:

Value: sk-ab••••••••••••••••••••••

Fallback Behavior​

If the key is not found in the active .env file, the tooltip shows:

ENV Manager
KEY: MISSING_VAR
⚠ Not found in any .env file

This gives you a visual cue without having to switch to the sidebar or run a diagnostic scan.

Multi-File Resolution​

The hover provider checks all .env* files in the workspace and shows the value from the most recently active file. If the key exists in multiple files with different values, the active file's value takes priority.
