It supports syntax up to ECMA 2025 and is built on a faithful Python port of the original esprima library, extended with modern ECMAScript features that the upstream projects no longer maintain. The parser produces output in the ESTree standardized format, making it compatible with tools and libraries that expect that structure.\n\nYou use it to analyze or manipulate JavaScript code from Python\u2014tokenizing to extract individual language elements, or parsing to build a complete syntax tree for traversal, transformation, or code generation. It includes experimental JSX support and optional source location tracking. The package is backed by roughly 1500 unit tests and requires Python 3.10 or later.","worth_installing":"Yes, if you need to parse modern JavaScript from Python. The package is actively maintained, has no dependencies, installs easily, carries a permissive license, and supports current ECMAScript syntax. It is relatively new (first release July 2025) but shows active development and reasonable test coverage. No known security vulnerabilities. The main caveat is that JSX support is marked experimental, so verify it meets your needs if you rely on that feature."},"id":"esprima2","links":{"html":"https://skillfed.io/packages/esprima2","md":"https://skillfed.io/packages/esprima2.md","pypi":"https://pypi.org/project/esprima2/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-22","license_spdx":null,"license_treatment":"permissive","name":"esprima2","python_support":"supports_current","summary":"high-performance javascript parser, tokenizer and lexical analyser"},"popularity":{"monthly_downloads":262895,"position":8366,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"6.0.0"}
