file-classes v2.0.1

File Classes

Do struggle when dealing with saving state in your program? Is it annoying? Well not anymore!

npm install file-classes or yarn add file-classes is a solution to the age old problem of syncing a piece of data in a program to the actual file store of your device.

With version 2 it works with XML, YAML, and JSON data! It's currently a bit clunky to use, but eventually that will be worked on.

It works like this...

import { JsonFile } from 'file-classes';
// Declare your store. (Provide type in the <> if you use TS for intellisense)
const store = new JsonFile<{ test: number; string: number }>('./store.json');

// Write data to the store
store.write({test: 0});

// Update test to a random number
store.updateVal("test", 135135);
// Get the value of test from the store.
store.getVal("test") // -> 135135

And of course you can also import XmlFile and YamlFile if you want to work with them. YAML files are parsed and written to using yaml XML Files are parsed and written to using xml-js

NOTE: XML Files come with some extra utilities for modifying the data since XML is more complex than JSON. If you don't use these you can run into pitfalls (check Pitfalls)

Pitfalls

1. Watch out when using .get() with XML Files. The value of tags is actually stored under propertyPath.text example xmlJson.test.data._text instead of xmlJson.test.data.

   Avoid this by using the XmlFile "val" "property" and "attribute" methods for getting + updating.

   <test>
       <data>
           THIS IS THE VALUE OF `xmlJson.test.data._text`
       </data>
   </test>

2. If you use .get() and then modify a JSON object, make sure to save those changes with .write(object) using the updated object.

Upcoming Features

1. Setting to compliment just updating data, so you can specify a property path and have it automatically created.
2. Support for more file types as needed, if you have any suggestions, post them on the Github repo under issues.
