Lintmesh

Unified linter runner. One command, JSON output, all issues sorted by file:line.

Usage

# Lint everything (default: eslint + oxlint + tsc)
lintmesh --quiet

# Lint specific paths
lintmesh --quiet src/

# Select linters
lintmesh --quiet --linters eslint,oxlint

Always use --quiet to suppress stderr progress.

Output Schema

{
  issues: Array<{
    path: string;           // Relative to cwd
    line: number;           // 1-indexed
    column: number;
    severity: "error" | "warning" | "info";
    ruleId: string;         // "eslint/no-unused-vars", "oxlint/no-debugger", "tsc/TS2322"
    message: string;
    source: string;         // Which linter
    fix?: {                 // Present if autofixable
      replacements: Array<{ startOffset: number; endOffset: number; text: string }>;
    };
  }>;
  summary: { total: number; errors: number; warnings: number; fixable: number };
  linters: Array<{ name: string; success: boolean; error?: string }>;
}

Patterns

# Error count
lintmesh --quiet | jq '.summary.errors'

# Files with issues
lintmesh --quiet | jq -r '.issues[].path' | sort -u

# Only errors
lintmesh --quiet | jq '[.issues[] | select(.severity == "error")]'

# Check if clean
lintmesh --quiet && echo "No errors"

When to Use

• After editing code: catch issues early
• Before committing: verify no regressions
• Debugging CI: reproduce locally with same format
