Infer the data-type of your variables
Sometimes you want to dynamically infer/guess the best datatype to allocate to a variable.
This module was written as a part of a CMS that guesses the most appropriate data-type to save data in where the user has not defined it.
Getting started
npm install --save typize
OR if you fancy yarn
yarn add typize
Start Checking Types
const typize = ; var values = "http://www.ietf.org/rfc/rfc2732.txt" '💯' '2015-1-11 13:57:24'; values
This will output:
Understanding the results
First, I wrote this module for a project I was working on to be able to detect data-types but also attempt to infer what type of strings I had.
So I added two properties:
- value.inferred : This property holds the value of the data as converted to the inferred datatype. For example, a value of "1" will be inferred to as an "integer" datatype and thus "value.inferred" will be the numeral 1.
- schema.format : This value indicates whether any more detailed data-types can be inferred from strings. The example above tells us that "http://www.ietf.org/rfc/rfc2732.txt" is not only a string but also a "remote_file".
Formats include:
- emoji
- url
- list (for comma delimited values such as "man,woman,child")
- color
- file
- remote_file
- markup

Disclaimer
NOTE: This module attempts to best guess the user data-type and will not be accurate 100% of the time. Use cautiously.
