# ldbdump

![CI](https://github.com/haraldF/ldbdump/workflows/emscripten%20CI/badge.svg)

Simple node.js package to dump a [LevelDB](https://github.com/google/leveldb) database.

Uses `emscripten` to build the C++ code so it'll work everywhere.
No custom compilation on installation required.

  A tool to introspect a leveldb database

  <db_path>    directory of the cache
  [key]        optional - dumps the value for the given key to stdout
```

Pass the path to the database directory as first argument to see all keys.
Pass a key as second parameter to dump the value for the given key.
