ts-standard configuration in MegaLinter	How to use ts-standard (configure, ignore files, ignore errors, help & version documentations) to analyze TYPESCRIPT files

TypeScript Standard Style is the TypeScript edition of the popular JavaScript Standard Style that brings zero-configuration linting and formatting to TypeScript projects. It extends the proven JavaScript Standard rules with TypeScript-specific enhancements and type-aware analysis.

Key Features:

Zero Configuration: No setup files or configuration required - install and run immediately
TypeScript-Aware: Built-in understanding of TypeScript syntax, types, interfaces, and modern features
Automatic Fixing: Built-in --fix option automatically corrects most style violations and type issues
Standard Rules: Maintains the same proven style rules as JavaScript Standard (2-space indent, single quotes, no semicolons)
Type Safety: Enforces TypeScript best practices and type safety patterns
Fast Performance: Quick analysis suitable for large TypeScript codebases
Wide Adoption: Used by TypeScript projects that prefer the Standard style approach over ESLint configurations
Consistent Output: Deterministic formatting across different development environments and team members

Help content

ts-standard - Standard for TypeScript! (https://github.com/standard/ts-standard)

Usage:
  ts-standard <flags> [FILES...]

  If FILES is omitted, all JavaScript/TypeScript source files (*.js, *.jsx, *.mjs, *.cjs, *.ts, *.tsx)
  in the current working directory are checked, recursively.

  Certain paths (node_modules/, coverage/, vendor/, *.min.js, and
  files/folders that begin with '.' like .git/) are automatically ignored.

  Paths in a project's root .gitignore file are also automatically ignored.

Flags:
      --fix       Automatically fix problems
  -p, --project   Specify ts-config location (default: ./tsconfig.eslint.json or ./tsconfig.json)
      --version   Show current version
  -h, --help      Show usage information

Flags (advanced):
      --stdin     Read file text from stdin
      --ext       Specify JavaScript/TypeScript file extensions
      --global    Declare global variable
      --plugin    Use custom eslint plugin
      --env       Use custom eslint environment
      --parser    Use custom ts/js parser (default: @typescript-eslint/parser)
