//this is helpers.js
'use strict'

var jsonSafeStringify = require('json-stringify-safe')
var crypto = require('crypto')
var Buffer = require('safe-buffer').Buffer

var defer = typeof setImmediate === 'undefined'
  ? process.nextTick
  : setImmediate

function paramsHaveRequestBody (params) {
  return (
    params.body ||
    params.requestBodyStream ||
    (params.json && typeof params.json !== 'boolean') ||
    params.multipart
  )
}

function safeStringify (obj, replacer) {
  var ret
  try {
    ret = JSON.stringify(obj, replacer)
  } catch (e) {
    ret = jsonSafeStringify(obj, replacer)
  }

function toBase64 (str) {
  return Buffer.from(str || '', 'utf8').toString('base64')
}

function copy (obj) {
  var o = {}
  Object.keys(obj).forEach(function (i) {
    o[i] = obj[i]

    patch: parseInt(numbers[2], 10)
  }
}

exports.paramsHaveRequestBody = paramsHaveRequestBody
exports.safeStringify = safeStringify
exports.md5 = md5
exports.isReadStream = isReadStream
exports.toBase64 = toBase64
exports.copy = copy

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

It looks like you did something wrong with your installation of crypto, I don't see how this is a react-native issue.

Even when i didnt install crypto its not from crypto installation

Please create a repro that shows that the issue is caused by react-native and I'll reopen the issue.

@mameya007 a few things:

1. have you tried replicating in the latest version of RN? (the proj you linked is on 0.55)
2. it seems that you have both crypto (which I feel you should not have in the package.json) and an outdated version of react-native-crypto, have you tried migrating to the latest version and reinstalling properly? It seems that it's kinda hacky, the installation flow, so I suggest that you open an issue there since I feel it may be related to that https://github.com/tradle/react-native-crypto
