sublink
Like level-sublevel but with links to nested keyspaces.
Why
So you can make traversable hierarchies.
How
Keys are sorted as utf8. U+10FFFF (0xF4, 0x8F, 0xBF, 0xBF) is used as a separator (so you can use any unicode string as a key), and keys pointing to nested keyspaces are suffixed with U+0000 (0x00) so they can be detected without reading any value data.
Example
var memup = var Sublink = var db = db
Install
$ npm install sublink
Test
$ npm run test
Notes
- Currently options are passed through to underlying levelup calls, however altering keyEncoding would break this module so maybe don't do that.
Changelog
4.0.0
- Add read / write locking. The implementation is primitive for now, it requires all write operations to hold a global lock.
3.0.0
- Don't require explictly deletes before overwrites - higher level modules can handle this
- Expose public
name
property - Add public
superlink
method
2.0.0
- Require explicitly deleting sublinks before overwriting with a value and vice-versa
1.0.0
- First working version
