base-store

base-methods plugin for getting and persisting config values. Adds a 'store' object that has all of the methods from the data-store library.

For example, by adding this plugin you can do this:

app.set('a', 'b');
app.store.set('a', 'z');

console.log(app.get('a'));
//=> 'b';
console.log(app.store.get('a'));
//=> 'z';

Additionally, store.set persists values to disk, but set does not.

The goal is to have methods dedicated to getting and persisting config values, while cleanly co-existing with the methods that deal with getting and setting values in-memory.

Install

Install with npm

$ npm i base-store --save

API

Add store and base to your application:

var store = require('base-store');
var Base = require('base-methods');
var base = new Base();

Register the store plugin with base-methods:

// store `name` is required
base.use(store('foo'));

// pass options (like cwd) as the second arg.
// default cwd is `~/data-store/`
base.use(store('foo', {cwd: 'a/b/c'}));

example

base.store
  .set('a', 'b')
  .set({c: 'd'})
  .set('e.f', 'g')

console.log(base.store.get('e.f'));
//=> 'g'

console.log(base.store.get());
//=> {name: 'app', data: {a: 'b', c: 'd', e: {f: 'g' }}}

console.log(base.store.data);
//=> {a: 'b', c: 'd', e: {f: 'g'}}

plugin params

• name {String}: Store name.

• options {Object}

• cwd {String}: Current working directory for storage. If not defined, the user home directory is used, based on OS. This is the only option currently, other may be added in the future.

• indent {Number}: Number passed to JSON.stringify when saving the data. Defaults to 2 if null or undefined

methods

Example

// key, value
base.store.set('a', 'b');
//=> {a: 'b'}

// extend the store with an object
base.store.set({a: 'b'});
//=> {a: 'b'}

// extend the the given value
base.store.set('a', {b: 'c'});
base.store.set('a', {d: 'e'}, true);
//=> {a: {b 'c', d: 'e'}}

// overwrite the the given value
base.store.set('a', {b: 'c'});
base.store.set('a', {d: 'e'});
//=> {d: 'e'}

.store.union

Add or append an array of unique values to the given key.

Params

• key {String}

Example

base.store.union('a', ['a']);
base.store.union('a', ['b']);
base.store.union('a', ['c']);
base.store.get('a');
//=> ['a', 'b', 'c']

.store.get

Get the stored value of key, or return the entire store if no key is defined.

Params

• key {String}
• returns {any}: The value to store for key.

base.store.set('a', {b: 'c'});
base.store.get('a');
//=> {b: 'c'}

base.store.get();
//=> {b: 'c'}

.store.has

Returns true if the specified key has truthy value.

Params

• key {String}
• returns {Boolean}: Returns true if key has

Example

base.store.set('a', 'b');
base.store.set('c', null);
base.store.has('a'); //=> true
base.store.has('c'); //=> false
base.store.has('d'); //=> false

.store.hasOwn

Returns true if the specified key exists.

Params

• key {String}
• returns {Boolean}: Returns true if key exists

Example

base.store.set('a', 'b');
base.store.set('b', false);
base.store.set('c', null);
base.store.set('d', true);

base.store.hasOwn('a'); //=> true
base.store.hasOwn('b'); //=> true
base.store.hasOwn('c'); //=> true
base.store.hasOwn('d'); //=> true
base.store.hasOwn('foo'); //=> false

.store.save

Persist the store to disk.
