// will send an error to slack channel
streamErrorSlack(slackWebHook, error);The package that stored the frequently used constant values on SSN.
var ssnConstants = require('sdk.nodejs.ssn.digital');
console.log(ssnConstants.STATUS_PENDING); // pendingconst STATUS_PENDING = 'pending';
const STATUS_VERIFYING = 'verifying';
const STATUS_COMPLETED = 'completed';
const STATUS_FAILED = 'failed';
const STATUS_CANCELED = 'canceled';
const STATUS_REJECTED = 'rejected';The package is use for api response standard format with options send to slack.
const { apiResponse } = require('sdk.nodejs.ssn.digital');
// NOTE: Please use in middleware as example below:
module.exports = function (req, res, next) {
const opts = {
slack: true | false, // by default false is not send to slack
name: 'environment',
url: 'slack webhook url'
}
apiResponse(req, res, opts)
next()
}Generic functions for formatting phone numbers.
var { toPrefixWithEightFiveFive } = require('sdk.nodejs.ssn.digital');
console.log(toPrefixWithEightFiveFive('085222111'));
// output: 85585222111var { toPrefixWithZero } = require('ssn-phone');
console.log(toPrefixWithZero('85585222111'));
// output: 085222111
