    Redis

    Redis

    An in-memory database that persists on disk

    Redis is an open-source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing an element to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set. To achieve top performance, Redis works with an in-memory dataset. Depending on your use case, you can persist your data either by periodically dumping the dataset to disk or by appending each command to a disk-based log.

    sqlite3

    sqlite3

    Asynchronous, non-blocking SQLite3 bindings for Node.js

    Straightforward query and parameter binding interface. Full Buffer/Blob support. Extensive debugging support. Query serialization API. Extension support, including bundled support for the json1 extension. Big test suite, written in modern C++ and tested for memory leaks. Bundles SQLite3 3.32.3 as a fallback if the installing system doesn't include SQLite. The module uses node-pre-gyp to download a pre-compiled binary for your platform, if it exists. Otherwise, it uses node-gyp to build the extension. It is also possible to make your own build of sqlite3 from its source instead of its npm package. It is possible to use the installed package in node-webkit instead of the vanilla Node.js. See Building for node-webkit for details. The sqlite3 module depends only on libsqlite3. However, by default, an internal/bundled copy of sqlite will be built and statically linked, so an externally installed sqlite3 is not required.

    Linenoise

    Linenoise

    A small self-contained alternative to readline and libedit

    Linenoise is an ultra-lightweight, self-contained C library that implements line editing (single and multi-line) for terminal applications, intended as a simpler alternative to the much larger GNU Readline or libedit libraries. The library is zero-config, meaning you just include the source file(s) and use it, without heavy dependencies or external configuration. It supports basic editing features: moving the cursor, inserting characters, handling history, tab-completion, and hints, plus a multiplexing mode where the prompt can be hidden/restored when asynchronous output appears. It works on most VT100/ANSI-compatible terminals, and is portable across Unix-like systems. The code is compact (around 850 lines excluding comments) and designed for minimal footprint embedding into other projects (like CLI tools) that need line editing but don’t want the complexity of linking large libraries.
