Spices - Anise

Javascript utility library for parsing the document.location

Usage

import {Anise, Field} from '@spices/anise'

let args = Anise.detect({
  new Field({
    name: 'lang', 
    fallback: 'en', 
    path: /.?\/(de|en|es)\/?.?/,
    persistent: true, 
    search: /lang=(de|en|es)/,
    values: ['de', 'en', 'es'],
  })
});

Will yield

• / -> {lang="en"} - Because en is the fallback value .
• /fr -> {lang="en"} - Because fr is not in the value list, therefor it takes only the valid values.
• /en?lang=de -> {lang="de"} - Because the search values will override the path values.

Field

• fallback - The fallback if the field is not found. The default value.
• name - The value used to identify the field
• path | - The path regexp to test against. Or the function to call to check whether or not the arguments is part of the pathname
• persistent - Whether or not use the localstorage are a source and provider
• search | The search regexp to test against. Or the function to call to check whether or not the arguments is part of the search query string
• validator A function use to determine Whether or not the value detected is valid or not
• values A list of allowed values for the field. Will be used to check against for validity.

How does it work?

When triggering the method Anise.detect, @spices/anise will check for the fields in the following sequence:

1. Use the fallback to setup the default values
2. Look for the persistent values in the localStorage
3. Look at the document.location.pathname for field matching the path
4. Look at the document.location.search for field mathing the search
5. Persists the information when needed
