Le db

Generator style node interface to LevelDB.

Usage

``js
var le = require('le');
var co = require('co');

var db = le('db');

co(function*(){
yield db.set('foo', 'bar');
console.log('foo: %s', yield db.get('foo'));
})();
`

Installation

`bash
$ npm install le
`

Roadmap

- [x] get, set, delete
- [x] batches
- [x] prefix ranges
- [x] interval ranges
- [ ] test suite
- [ ] streaming iteration
- [ ] encodings
- [ ] plugin interface (no monkey patching!)
- [ ] nesting
- [ ] client

API

$3

Create or open the db at path.

$3

Get the value at key.

$3

Set the value at key to value.

$3

Delete the value at key.

$3

Create a batch.

$3

Queue setting key to value.

$3

Queue deleting the value at key.

$3

Write the batch of operations.

$3

Get all keys (inside range).

$3

Get all values (whose keys are inside range).



Ranges

db#keys() and db#values() accept string ranges of those formats:

- ""/"*": get all
- "prefix*": all keys must start with prefix
- "[from,to]", "[from,to)", "(from,to]", "(from,to)": all keys must be
inside the interval, see
interval notations#Classification_of_intervals).
For infinity to x and vice versa omit the boundary, like [,to].

Encoding

For now, everything is stored as JSON`.

Y u do this

- want db.use() instead of monkey patching
- generators for async ops
- __generators for streams__
- efficient nesting and less verbose ranges
