yamllint-ts VS Code Extension

A VS Code extension for linting YAML files using yamllint-ts, a native TypeScript implementation of the popular Python yamllint tool.

Features

  • Native TypeScript - No Python installation required
  • Real-time linting - See errors as you type
  • Configurable - Uses standard yamllint configuration format
  • Full compatibility - Supports the same rules as Python yamllint

Configuration

The extension looks for configuration files in the following order:

  1. Path specified in yamllint.config setting
  2. .yamllint, .yamllint.yaml, .yamllint.yml, or .yamllint.json in workspace root
  3. Default configuration (if no config file found)

Settings

Setting Type Default Description
yamllint.enable boolean true Enable or disable yamllint
yamllint.config string "" Path to yamllint configuration file
yamllint.lintOnSave boolean true Lint files when saved
yamllint.lintOnChange boolean true Lint files as you type
yamllint.lintOnOpen boolean true Lint files when opened
yamllint.debounceTime number 300 Debounce time (ms) for linting on change

Example Configuration File

Create a .yamllint or .yamllint.yaml file in your workspace:

---
extends: default

rules:
  line-length:
    max: 120
    level: warning
  indentation:
    spaces: 2
  document-start: disable

Commands

  • yamllint: Lint Current File - Manually lint the current YAML file
  • yamllint: Lint All YAML Files in Workspace - Lint all YAML files in the workspace

Available Rules

All standard yamllint rules are supported:

Rule Description
anchors Control use of anchors and aliases
braces Control spacing inside braces {}
brackets Control spacing inside brackets []
colons Control spacing around colons
commas Control spacing around commas
comments Control comment formatting

Why yamllint-ts?

Unlike other VS Code YAML linters that shell out to the Python yamllint binary:

  • No dependencies - Works out of the box without Python
  • Faster - No process spawning overhead
  • Better integration - Native TypeScript enables richer IDE features
