Edit: is-default-value.js
'use strict'; // This example shows how to understand if a default value is used or not. // 1. const { parseArgs } = require('node:util'); // from node // 2. const { parseArgs } = require('@pkgjs/parseargs'); // from package const { parseArgs } = require('..'); // in repo const options = { file: { short: 'f', type: 'string', default: 'FOO' }, }; const { values, tokens } = parseArgs({ options, tokens: true }); const isFileDefault = !tokens.some((token) => token.kind === 'option' && token.name === 'file' ); console.log(values); console.log(`Is the file option [${values.file}] the default value? ${isFileDefault}`); // Try the following: // node is-default-value.js // node is-default-value.js -f FILE // node is-default-value.js --file FILE
