toLocaleString not working on firebase cloudFunctions

Question

My node 8 function, hosted at Firebase Cloud Functions isn't working as expected. I've a toLocaleString call passing all parameters to format in Brazilian currency format, but I getting the default EN format. The function: const value = 10825.20645 const formatted = value.toLocaleString('pt-br', { style: 'currency', currency: 'BRL', decimals: 2 }) Expected result R$ 10.825,21 Actual result at CloudFunction R$ 10,825.21 Running the same function on browser is working fine const value = 10825.20645 const formatted = value.toLocaleString('pt-br', { style: 'currency', currency: 'BRL', decimals: 2 }) console.log(formatted) // R$ 10.825,21 Run code snippetExpand snippet JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

To solve this (in part, I'll explain), I used INTL API as suggested by @hybrdthry911. By default, nodejs only load the EN lang. const intl = require('intl') const locale = intl.NumberFormat('pt-br', { style: 'currency', currency: 'BRL', decimals: 2 }) const value = 10825.20645 const formatted = locale.format(value) console.log(formatted) // R$10.825,21 But, it still different from my expected result. In browsers, I get an space after the currency symbol, but with INTL. Expected: R$ 10.825,21 Result: R$10.825,21 It's a small problem, I'll do a search about.
