BigInt support for JSON encoding

JSON BigInt

JavaScript library that allows encoding JSON with BigInt support.

JavaScript JSON API doesn't work with numbers too big. If you are working with 64-bit integers in your server, this library got you covered. 64-bits integers will be parsed as bigint 😉

No dependencies. 443 bytes.

Example

import JSONBigInt from 'https://unpkg.com/@nicolasparada/json-bigint@0.5.0/json-bigint.js'

const input = '{"big":9223372036854775807,"small":123}'
console.log('input:', input)

const r1 = JSON.parse(input)
console.group('built-in JSON')
console.log('parsed:', r1)
console.log('stringified:', JSON.stringify(r1))
console.groupEnd()

const r2 = JSONBigInt.parse(input)
console.group('JSONBigInt')
console.log('parsed:', r2)
console.log('stringified:', JSONBigInt.stringify(r2))
console.groupEnd()
input: {"big":9223372036854775807,"small":123}

built-in JSON
    parsed: { big: 9223372036854776000, small: 123 }
    stringified: {"big":9223372036854776000,"small":123}

JSONBigInt
    parsed: { big: 9223372036854775807n, small: 123 }
    stringified: {"big":9223372036854775807,"small":123}
