code-generator-js

JavaScript implementation of code-generator

Installation

npm install -g code-generator-js

Tip

This implementation is very slow compared to the original package written in Go. The only reason for building this package was to compare performance. When generating 100.000 codes Go performs 530 % faster than this implementation.

Options

-h, --help         output usage information
-v --version       output the version number
-p, --pattern <p>  Code pattern l for letter, n for number and - for dash
-l, --length <l>   Number of codes to generate
-c, --case <c>     Number of codes to generate [upper] [lower]

Usage

Generate a single code. (codes.txt is saved in current directory)

code
//=> Generated: 1/1 codes
//=> Done. Codes saved to codes.txt
//=> Generation took: 14.118ms

Generate codes using a pattern (l for letters. n for number. - or any character for dash)

code --pattern nnnn-llll
//=> Generated: 1/1 codes
//=> Done. Codes saved to codes.txt
//=> Generation took: 14.118ms

Generate a thousand codes with nnnn-llll pattern

code --pattern nnnn-llll --length 1000
//=> Generated: 1000/1000 codes
//=> Done. Codes saved to codes.txt
//=> Generation took: 55.938ms

Generate a thousand uppercase codes with nnnn-llll pattern

code --pattern nnnn-llll --length 1000 --case upper
//=> Generated: 1000/1000 codes
//=> Done. Codes saved to codes.txt
//=> Generation took: 55.938ms
