Local Storage Programming Interface

Basic ORM for local storage that can save you time!

Super easy to use!

Store and retrieve valid JSON objects/arrays or simple strings :smile:

Make sure to use polyfills for Array.from and Object.assign when bundling your application code! :tada:

Install

npm install lspi --save

Basics

const lspi = require('lspi');

//= set string ->
lspi.set('testOne', 'testing');
// Returns: undefined
// Stores: "testing"

//= get string ->
lspi.get('testOne');
// Returns: "testOne"

//= set object literal ->
lspi.set('testOne', {});
// Returns: undefined
// Stores: "{}"

//= get object literal ->
lspi.get('testOne');
// Returns: {}

//= set array ->
lspi.set('testTwo', []);
// Returns: undefined
// Stores: "[]"

//= get array ->
lspi.get('testTwo');
// Returns: []

//= set array of objects ->
lspi.set('testOne', [{ name: 'test' }, { name: 'test2' }]);
// Returns: undefined
// Stores: "{"name": "test2"}"

//= where query on array of objects ->
lspi.where('testOne', 'name', 'test2');
// Returns: [{ name: 'test2' }]

//= update state ->
lspi.set('test42', { hey: 'hi' });

lspi.update('test42', { ok: 'new stuff' });
// Returns: undefined
// Adds ok key and 'new stuff' value to the 'testOne' record

lspi.update('test42', { hey: 'hello' });
// Returns: undefined
// Updates hey value to 'hello' instead of 'hi'

//= remove data (singular) ->
lspi.drop('testOne');
// Returns: undefined
// This will delete the 'testOne' record from localStorage

//= remove all data ->
lspi.dropAll();
// Returns: undefined
// Drops ALL localStorage associated to your domain

//= Mutiple set ->
lspi.sets(['test', { wow: 'wow1' }], ['test2', { wow: 'wow2' }]);
// Returns: undefined
// Stores: {wow: 'wow1'} in mthe 'test' key
// Stores: {wow: 'wow2'} in the 'test2' key

const testDataOne = lspi.get('test');
const testDataTwo = lspi.get('test2');

testDataOne; // => {wow: 'wow1'}
testDataTwo; // => {wow: 'wow2'}

//= Multiple get ->\
lspi.sets(['test', { wow: 'wow' }], ['test2', { wow: 'wow' }]);

const testData = lspi.gets('test', 'test2');

testData; // => ['test', {wow: 'wow'}], ['test2', {wow: 'wow'}]

//= Multiple drop ->
lspi.sets(
  ['test', { wow: 'wow1' }],
  ['test2', { wow: 'wow2' }],
  ['test3', { wow: 'wow3' }],
);

lspi.drops('test', 'test2');
// Returns: undefined
// 'test3' -> {wow: 'wow3'} remains
