Note: A tsconfig.json or similar project file is required. See TSConfig section below for more details

📜 Help

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)

🧬 TSConfig: Linting with Type Information

By default ts-standard will search the current working director (cwd) for the following in order

  1. tsconfig.eslint.json
  2. tsconfig.json

You can also manually configure the location of the tsconfig file by either passing the path to the --project flag or adding a ts-standard configuration property to your package.json file.

{
  "ts-standard": {
    "project": "path/to/tsconfig.json"
  }
}

🗑 Ignoring files and folders

You can add an ignore property to your package.json ts-standard configuration settings.

{
  "ts-standard": {
    "ignore": [
      "dist",
      "src/**/*.js"
    ]
  }
}

🚫 Please change X rule

This project has no control over the rules implemented, as such this project cannot change any of the rules that have been configured. If you want to discuss the rules, please visit the rules configuration repo eslint-config-standard-with-typescript.

🧙 Why

This utility was designed to be the standard equivalent for typescript. Underneath the hood, this utility uses the same standard-engine and combines that engine with the official eslint-config-standard-with-typescript ruleset.

You can also choose to just use eslint with the eslint-config-standard-with-typescript shareable config instead and achieve the same results as this project. But ts-standard saves you from having to manually install all the extra dependencies and may reduce configuration overhead.

🎉 Special Thanks

Special thanks to standard for inspiration and some shared code and to eslint-config-standard-with-typescript for creating a typescript specific standard.
