js-toolbelt.js Is a basic javascript library to help us with day-to-day development for do not waste time with small tasks, do us wasting time researching books, google and filling our code with unnecessary lines.
$ npm install js-toolbelt --saveThe current version of js-toolbelt has one library (ValidNumber) with a set of useful functions. To enable
them, just use the require as shown below:
var vn = require('js-toolbelt').ValidNumber;vn.isNumeric(fieldToCheck)
Checks the fieldToCheck argument and returns true if it owns only number, otherwise returns false
console.log(vn.isNumeric('12345')); // true
console.log(vn.isNumeric('abc12345')); // falsevn.returnOnlyNumber(fieldToModify)
Returns only numbers from the fieldToModify argument
console.log('abc123/4-5'); //12345
console.log(vn.returnOnlyNumbers('02.934.311/0001-53')); // '02934311000153'vn.isCnpj(cnpjToCheck)
Checks if the cnpj number is a valid document, if yes return true, otherwise, false.
P.S. cnpj is the main and only registration number of a company in Brazil, valid in national territory, has its own format and verification code.
console.log(vn.isCnpj('02.934.311/0001-53')); // true
console.log(vn.isCnpj('02.934.311/0001-53')); // true
console.log(vn.isCnpj('s0s2s.s9s3s4s.s3s1s1s/s0s0s0s1s-s5s3s')); // true
console.log(vn.isCnpj('12.934.311/0001-53')); // false
console.log(vn.isCnpj('')); // false
console.log(vn.isCnpj()); // falsevn.returnCnpjWithMask(cnpj)
Return the cnpj with a valid mask (99.999.999/9999-99)
P.S. cnpj is the main and only registration number of a company in Brazil, valid in national territory, has its own format and verification code.
console.log(vn.returnCnpjWithMask('02934311000153')); // '02.934.311/0001-53'
console.log(vn.returnCnpjWithMask('0abc29 3431--1000153')); // '02.934.311/0001-53'
console.log(vn.returnCnpjWithMask('12934311000153')); // false (is an invalid cnpj)
console.log(vn.returnCnpjWithMask('abc')); // falsevn.generateCnpj(withMask)
Returns a valid cnpj number (but fake). If the withMask argument is true, cnpj will returned in its default format (02.934.311/0001-53), otherwise, it returns only numbers (02934311000153)
P.S. cnpj is the main and only registration number of a company in Brazil, valid in national territory, has its own format and verification code.
console.log(vn.isCnpj(vn.generateCnpj())); // true : confirm that is a valid cnpj (fake)
console.log(vn.generateCnpj()); // only numbers (99999999999999) and a valid cnpj (fake)
console.log(vn.generateCnpj(true).length); // 18 : length with mask (99.999.999/9999-99)vn.validateObjectId(ObjectId)
Return true if the ObjectId argument is a valid ObjectId for MongoDB.
console.log(vn.isObjectId('58835cf81490ba3ac4898f5e')); // true);
console.log(vn.isObjectId()); // false);
console.log(vn.isObjectId('abcdefghijklmnopqrstuvx')); // false);- Rick Biruel @RicardoBiruel
