svelte-eslint-parser

• Purpose: A parser that enables ESLint to analyze and lint Svelte components, allowing developers to create custom ESLint rules for Svelte applications.
• Target Audience: Developers working with Svelte who want to enforce code quality and consistency through ESLint rules.
• Key Features:
  • Parses Svelte components into an AST (Abstract Syntax Tree) compatible with ESLint.
  • Supports TypeScript within Svelte <script> tags when configured with @typescript-eslint/parser.
  • Provides scope analysis for Svelte templates and scripts.
  • Configurable for Svelte 5 features like runes via parserOptions.svelteFeatures.
• Svelte Support: Primarily designed for Svelte, with first-class support for .svelte files and Svelte-specific syntax.
• Related Plugins:
  • eslint-plugin-svelte : Official ESLint plugin built on this parser, offering Svelte-specific rules.
  • @intlify/eslint-plugin-svelte : Adds i18n (internationalization) linting for Svelte apps.
• Tooling Integration: Works with editors like VS Code via the ESLint extension, requiring configuration to include .svelte files.
• Customization: Developers can extend functionality by writing custom ESLint rules using the provided AST structure (documented in AST.md ).
