Layers
Modules that implement abstract-leveldown
to wrap another abstract-leveldown
. This is the preferred extension point.

Provides key/value encoding.
@adorsys/encrypt-down
Provides encryption for values.
deferred-leveldown
Handles delayed-open. Built into levelup
.
level-cowdown
Copy-on-write abstract-leveldown
layer.

Encodings
Custom level-codec
compatible encodings for use with encoding-down
.
charwise
Encode/decode with same encoded sort order as bytewise
.
bytewise
Binary serialization which sorts bytewise for arbitrarily complex data structures. NB. Use charwise
if possible. Gives you almost everything bytewise
does but much faster.
protocol-buffers

compatible encodings.
lexicographic-integer-encoding

.
Sublevels
Modules related to splitting a database into sections a.k.a. sublevels.

database into sublevels with their own keyspace, encoding and events.

sublevel that is guaranteed to be empty.

stores by key prefix onto a single store. Can be used with subleveldown
.
bytespace
Keypath subspaces prefixed with bytewise
tuples. Similar to level-sublevel
. NB. bytewise
- and thus bytespace
- can be slow. Consider using subleveldown
paired with the charwise
encoding instead.
level-sublevel
Adds the ability to create subsections with the same API as levelup
, but only write/read to a prefixed section, or bucket, of the key-space. Each section also has level-hooks
installed. NB. No longer maintained. We recommend subleveldown
instead.

Find level-sublevel
sublevels, not requiring them to be in memory already.
level-subtree

sublevels, useful when there is no manifest.

sublevels and browsing the database without knowledge of the sublevel structure.

, with hooks. Adapted from level-sublevel
.

sublevel into another.

Yet another indexing plugin for levelup

and level-sublevel
, both of which have caveats.
level-inverted-index
Create an inverted index for full-text search.
map-reduce
A MapReduce implementation on top of levelup
. Allows you to define a map reduce query that will run on top of your db. The map reduces are incremental, and you can query the results in real-time.
