{"library":"meriyah","type":"library","category":null,"description":"Meriyah is a highly performant and stable JavaScript parser, currently at version 7.1.0, designed for 100% compliance with the ECMAScript® 2024 (ES-262 15th Edition) standard. It provides an ESTree-compatible Abstract Syntax Tree and operates without backtracking, contributing to its low memory footprint. While it actively supports Annex B (Web Browsers) features, JSX parsing, and select TC39 Stage 3 proposals like Decorators and JSON Modules via an opt-in `next` flag, it notably does *not* support TypeScript or Flow syntax. The project maintains a steady release cadence, frequently updating to reflect the latest ECMAScript specifications and address bug fixes, as evidenced by recent v6 and v7 patch and minor releases, ensuring it remains a cutting-edge tool for syntactic analysis.","language":"javascript","status":"active","version":"7.1.0","tags":["javascript","parsing","ecmascript","parser","estree","esnext","lexer","ast","typescript"],"install":[{"cmd":"npm install meriyah","imports":["import { parse } from 'meriyah';","import { isParseError } from 'meriyah';","import type { ParserOptions } from 'meriyah';"]},{"cmd":"yarn add meriyah","imports":[]},{"cmd":"pnpm add meriyah","imports":[]}],"homepage":null,"github":"https://github.com/meriyah/meriyah","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/meriyah","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/meriyah/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Mon Jul 20","install_tag":null}}
