vaultify

Conveniently manage the configuration file in your command-line project based on Node.js.

It just provides some simple features instead of a strict typecheck and validation cause a lighter package suit me a lot.

Inspiration comes from Tampermonkey api.

The configuration file will be stored default in C:/Users/USERNAME/AppData/Roaming/PROJECT_NAME/config.json on Windows, ~/.config/PROJECT_NAME/config.json on Linux and ~/Library/Preferences/PROJECT_NAME/config.json on macOS.

Install

npm install vaultify

Usage

import Vault from './vault'

const vault = new Vault({
  name: 'myproject'
})

// set a value
vault.set('first', 1)
console.log(vault.get('first')) // 1

// delete a value
vault.delete('first')
console.log(vault.get('first')) // undefined

Vault

All api is based on the Vault class.

Options

The Vault class accepts an options object with the following properties:

name [string, required]

The name of your project, it matters to the path of the configuration file.

displayNameTemplate [string]

Guess you want to change the name of the folder where the configuration file stored. It should contain a placeholder [NAME] which will be replaced by the name property. For example, if you set displayNameTemplate to config-[NAME] and name to myproject, the configuration file will be stored in the folder config-myproject.

fileName [string]

The name of the configuration file. Default is config.

fileExtension [string]

The extension of the configuration file. Default is json.

Of course you can set it to haha or whatever you like, even without an extension.

The configuration will be stored like a json, so whatever you set the extension to, it will be parsed as a json by default.

defaults [object]

The default values of the configuration file. It will be merged with the existing configuration file when the Vault instance is created. The existing values that have the same key will be kept.

obfuscate [boolean]

Whether to obfuscate the configuration file. Default is false.

It designed to prevent users from modifying the configuration file manually, maybe useful in some cases?

instance attributes and methods

set(key, value)

Set a value to the configuration file.

The dot notation is supported, which means you can set a nested value like this:

vault.set('a.b.c', 1)

// equals to
vault.set('a', {
  b: {
    c: 1
  }
})

Important

You should ensure the value is not undefined, Symbol or other values that cannot be stored in a json file.

get(key, defaultValue?)

Get a value from the configuration file. If the value is not found, it will return the defaultValue if provided, otherwise undefined.

Of course, the dot notation is supported.

delete(key)

Delete a value from the configuration file. The dot notation is supported.

reset(hard?)

Reset all values in the configuration file to the default values. If hard is true, all values will be removed.

store

The data object that stores all values in the configuration file.

It's writable, so you can reassign it to update the configuration file if you want, like this:

vault.store = {
  a: 1
}
