ErrorMap: IDE Plugin for Full-Project Error Aggregation

A VS Code/JetBrains plugin that runs TypeScript/JavaScript compiler in the background, aggregates ALL project errors (not just open files), and displays them in a dedicated sidebar panel with file-tree navigation, error grouping by severity/file, and one-click jump-to-fix. Developers see the complete error landscape without touching the terminal.

19 weeks • 70% confidence

Value Proposition

Eliminates terminal context-switching entirely by making full-project errors visible inside the IDE. Saves 5-10 hours/week per developer by surfacing all breaking changes instantly and letting them batch-fix by file or error type, not by random discovery.

Target Audience

Mid-to-large team leads and senior developers at agencies, startups, and enterprises shipping TypeScript/JavaScript projects with 100+ files

Key Features

  • Real-time full-project error aggregation (no manual build command needed)
  • Sidebar error tree grouped by file, severity, error type, or custom filters
  • One-click navigation to error location with inline fix suggestions (powered by TS language server)
  • And more, with full implementation detail...

Original Problem

Developers waste hours context-switching between terminal and IDE to find and fix errors across large codebases

In large TypeScript/JavaScript projects with hundreds of files, developers must manually run build commands in the terminal to see all project errors, then tediously search through their IDE to locate and fix each one. This fragmented workflow breaks focus and creates a painful gap between error discovery and resolution. Current IDE solutions only show errors in open files, forcing developers into a broken feedback loop of terminal-to-editor navigation.
