Error Radar

See every workspace error in one place.

Error Radar is a free VS Code extension that surfaces diagnostics (errors + warnings) across your entire codebase in a single panel, with fast filters and click-to-jump navigation.

What it does

Stop opening files one by one just to find what's broken.

Aggregates all diagnostics — errors and warnings from every file in your workspace, not just the currently open one
One-click navigation — click any item to jump directly to the exact file and line
Filter by severity — view all diagnostics, errors only, or warnings only
Sort controls — sort by severity (errors first) or alphabetically by file name
Auto-refresh — the panel updates automatically as diagnostics change
Status bar indicator — see your error/warning count at a glance without opening the panel
Multi-root workspace support — aggregates diagnostics across all workspace roots

Install

Install from the VS Code Marketplace.

Or press Ctrl+Shift+X (Windows/Linux) / Cmd+Shift+X (Mac), search for Error Radar, and click Install.

Usage

Click the Error Radar icon in the Activity Bar (radar icon on the left sidebar)
The Diagnostics panel shows all errors and warnings across your workspace
Click any item to jump to that exact location in the file
Use the toolbar icons to Refresh, Set Filter, or Set Sort

Commands

Command	Description
`Error Radar: Open Panel`	Focus the diagnostics panel
`Error Radar: Refresh`	Force-refresh the diagnostics list
`Error Radar: Set Filter`	Choose All / Errors only / Warnings only
`Error Radar: Set Sort`	Sort by Severity or File name

Access commands via Ctrl+Shift+P / Cmd+Shift+P and type Error Radar.

Running from Source (Dev)

git clone https://github.com/lmagee3/error-radar
cd error-radar
npm install

Then press F5 in VS Code to launch the Extension Development Host with Error Radar loaded.

Known Limitations

Diagnostics from language servers that haven't loaded yet won't appear until they initialize (use Refresh after the workspace fully loads)
For very large projects (>1000 diagnostics), scroll performance may vary depending on VS Code's tree view rendering
The icon.png marketplace icon needs to be exported from resources/icon.svg before publishing

Roadmap

[ ] Group diagnostics by file (collapsible tree)
[ ] Filter by source (ESLint, TypeScript, etc.)
[ ] Keyboard shortcut to cycle filter modes
[ ] Persistent filter/sort preferences across sessions
[ ] Export diagnostics to a report file
