• Support for node v22 by @jeffesquivels in #72

Full Changelog: v0.9.22...v0.11.1

v0.9.22

Update dependencies, include compatibility for current Node LTS.

v0.9.18

Changelog:

• Update packages
• Fix resulting ESLint errors
• Make LevelDB backend optional
  • Plan for next release: put backends plugin-like in separate packages

v0.5.0

Complete list of improvements:

• Improve indexing structure in NodeJS:
  Instead of storing a B+Tree in memory and persisting this tree to another table, we now directly make use of the indexing capabilities of the second table and use it to store the secondaryKey -> [primaryKeys] relation.
  Our benchmarks have shown this to be superior for write accesses, while the performance dropped slightly for read accesses.
• Integrate LMDB as an alternative backend:
  LMDB can now be seamlessly integrated. Our benchmarks have shown LMDB to be superior in performance especially for large values, large transactions and indices, even outperforming the previous in-memory B+Tree.
  Moreover, LMDB is a synchronous backend, allowing to reduce the number of async/await operations dramatically (while still maintaining the same API to the outside).
• Add new benchmarks and output CSV compatible format instead of text.
• Restructuring of LMDB backend, usage of native dup keys for LMDB indexes.
• Automatic resizing of database.

If the autoResize option is enabled, the database will automatically resize itself if needed by minResize (default is 1GB).

v0.4.3

Fix calls to createObjectStore using a codec and the deprecated arguments.

v0.4.2

Also catch exceptions occurring in user-callbacks.

v0.4.1

This version improves:

• error handling and avoids unhandled exceptions,
• upgrading of databases (by letting the developer specify a condition that certain upgrade commands are executed),
• some API calls with many options (by introducing an options object instead of a long list of parameters).

v0.4.0

Mainly adds support for synchronous transactions.

v0.3.8

Fixes a bug leading to a Transaction stack size exceeded error.

v0.3.7

Replace dumb JSON encoding by more sophisticated encoding (#15).
Add more logging.
