# Record.js
> A minimalistic object collection library
**Record.js** aims to provide a lite, *2kb*, *zero-dependency* collection utility to help build simple in-memory or local storage data records. Records are stored as arrays in a `JSON` object.
Records can export raw JSON records, with no internals, via `.dump()`
## WIP
Not done yet!
## Getting Started
- [Download Library](https://raw.githubusercontent.com/n2geoff/record.js/master/dist/record.min.js), then...
create a new record collection (in-memory)
const pets = new Record();
add something to the collection
pets.add({"name": "Fluffy", "type": "cat"});
// [{"id": "123fk91j7", "name": "Fluffy", "type": "cat"}]
an `id` field is auto-generated if not provided, this allows easy record retrieval via
pets.find("123fk91j7");
// [{"id": "123fk91j7", "name": "Fluffy", "type": "cat"}]
you can also find items via properties like
pets.find({"type": "cat"});
// [{"id": "123fk91j7", "name": "Fluffy", "type": "cat"}]
and you can remove items via
pets.remove("123fk91j7");
// [{"id": "123fk91j7", "name": "Fluffy", "type": "cat"}]
so, no records, right?
pets.find();
// []
### API
The public API is very simple, you really only need 3 methods: `add`, `remove`, and `find`.
| Method | Description |
|---|---|
| `.add(object)` | Adds entry to collection and returns entry(s) added |
| `.remove(id|object)` | Removes entry(s) from collection and returns removed |
| `.find(id|object)` | find all, find by id, or find by filter, returns array of entries |
| `.dump()` | saves records to JSON file |
#### Length (Count Records)
As `Records` are just plain JavaScript Arrays, you can use `.length` to determine the number of
results returned, for example:
```js
let cats = pets.find({"type": "cat"}); // []
cats.length; // 0
```
> NOTICE: `find` is special, changes based on what you pass in, an id, an object, or nothing at all
- Additional [API Documentation](docs/api.md)
### Options
Records.js constructor supports a few options passed in as an `object`
- store: localStorage KEY to use. This actives localStorage if available
- debug: may logout useful information, maybe not;)
