mlasq
Yet another indexedDB facade. Supports callbacks and promises API.
Install
$ npm install --save mlasq
Usage
With callbacks:
const mlasq = require('mlasq');
// create database and storage
const db = mlasq('My DB', [ 'horses', 'cats' ]);
// put, get, count, remove etc.
const cats = db.store('cats');
cats.put('burek', {
name: 'burek',
age: 3
}, function(err, key) {
assert.equal(key, 'burek');
// 'burek' now in DB
});
// close and remove db
db.close(function(err) {
console.log('closed now');
});
db.remove(function(err) {
console.log('all stores removed now');
});
With promises:
const mlasq = require('mlasq');
// create database and storage
async function doSometing() {
const db = mlasq('My DB', [ 'horses', 'cats' ]);
// put, get, count, remove etc.
const cats = db.store('cats');
const key = await cats.put('burek', {
name: 'burek',
age: 3
});
assert.equal(key, 'burek');
// close and remove db
await db.close();
console.log('closed now');
await db.remove();
console.log('all stores removed now');
}
API
For all methods fn
callback is optional. If fn
is not provided Promise
is returned that resolves to the result.
These are the object store methods:
put(key, item, fn)
Puts item
under the key
. Returns the key
.
get(key, fn)
Retrieves item
identified by key
.
getAll(fn)
Retrieves all items in the store.
getAllKeys(fn)
Retrieves all keys in the store.
update(key, item, fn)
Upserts item: if item identified by key
already exists it is merged (using Onject.assign
) with the passed item
.
Returns the key
and the updated value of the item.
remove(key, fn)
Removes item identified by the key
.
count(key, fn)
Counts number of items in store.
clear(fn)
Clears the store: removes all the items.
