{"library":"oppa","type":"library","category":null,"description":"Oppa is a typesafe options and arguments parser for Node.js, designed for command-line interfaces. It provides a fluent API for defining command-line arguments, including support for long/short names, aliases, boolean flags (with `--no-` prefix auto-handling), multi-value arguments, and custom validators. A key differentiator is its strong TypeScript integration, which ensures the parsed result is fully type-checked at compile-time, eliminating common runtime errors associated with parsing untyped arguments. It also automatically generates comprehensive `--help` and `--version` output. The current stable version is 0.4.0, released in June 2021, indicating a slower release cadence. It requires Node.js >=10, with specific build fixes for Node.js 10 in versions 0.3.3 and later.","language":"javascript","status":"maintenance","version":"0.4.0","tags":["javascript","oppa","argument","option","parser","options","arguments","typescript"],"install":[{"cmd":"npm install oppa","imports":["import { oppa } from 'oppa'","import { Oppa } from 'oppa'","import { TypeOf } from 'oppa'"]},{"cmd":"yarn add oppa","imports":[]},{"cmd":"pnpm add oppa","imports":[]}],"homepage":null,"github":"https://github.com/grantila/oppa","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/oppa","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/oppa/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Sat Jul 18","install_tag":null}}
