{"library":"estree-util-is-identifier-name","type":"library","category":null,"description":"estree-util-is-identifier-name is a focused utility from the unified collective designed to determine whether a given string or Unicode code point can constitute a valid ECMAScript (JavaScript) identifier name. The package, currently at stable version 3.0.0, provides functions like `name` to validate full identifier strings, and `start` and `cont` to check individual code points for starting or continuing an identifier. Major releases, such as v3.0.0, typically coincide with updates to Node.js compatibility (now requiring Node.js 16+) and significant internal changes like the adoption of `exports` for module resolution and enhanced Unicode support for astrals and code points. A key differentiator is its strict adherence to ECMAScript identifier rules, including optional support for JSX identifiers, while intentionally not handling language keywords. It's an ESM-only package since v2.0.0 and ships with full TypeScript types.","language":"javascript","status":"active","version":"3.0.0","tags":["javascript","estree","ast","ecmascript","tree","identifier","character","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install estree-util-is-identifier-name","imports":["import { name } from 'estree-util-is-identifier-name'","import { start } from 'estree-util-is-identifier-name'","import { cont } from 'estree-util-is-identifier-name'","import type { Options } from 'estree-util-is-identifier-name'"]},{"cmd":"yarn add estree-util-is-identifier-name","imports":[]},{"cmd":"pnpm add estree-util-is-identifier-name","imports":[]}],"homepage":null,"github":"https://github.com/syntax-tree/estree-util-is-identifier-name","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/estree-util-is-identifier-name","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/estree-util-is-identifier-name/compatibility"}}
