![]() However, there are some cases where better-sqlite3 could be inappropriate: If you have a performance problem, the most likely causes are inefficient queries, improper indexing, or a lack of WAL mode-not better-sqlite3 itself. With proper indexing, we've been able to achieve upward of 2000 queries per second with 5-way-joins in a 60 GB database, where each query was handling 5–50 kilobytes of real data. For example, if you're executing queries that take one second to complete, and you expect to have many concurrent users executing those queries, no amount of asynchronicity will save you from SQLite3's serialized nature. In most cases, if you're attempting something that cannot be reasonably accomplished with better-sqlite3, it probably cannot be reasonably accomplished with SQLite3 in general. better-sqlite3 is much faster than node-sqlite3 in most cases, and just as fast in all other cases.better-sqlite3 is simpler to use, and it provides nice utilities for some operations that are very difficult or impossible in node-sqlite3.better-sqlite3 does it the JavaScript way, allowing the garbage collector to worry about memory management. node-sqlite3 exposes low-level (C language) memory management functions.It also causes mutex thrashing which has devastating effects on performance. That's not only bad design, but it wastes tons of resources. node-sqlite3 uses asynchronous APIs for tasks that are either CPU-bound or serialized.Import Database from 'better-sqlite3' const db = new Database ( 'foobar.db', options ) Why should I use this instead of node-sqlite3? You can verify these results by running the benchmark yourself. If your company uses better-sqlite3, ask your manager to consider supporting the project: Long nights and weekends were spent keeping this project strong and dependable, with no ask for compensation or funding, until now. Worker thread support (for large/slow queries)īetter-sqlite3 is used by thousands of developers and engineers on a daily basis.64-bit integers (invisible until you need them).Support for user-defined functions, aggregates, virtual tables, and extensions.Easy-to-use synchronous API (better concurrency than an asynchronous API.High performance, efficiency, and safety. ![]() The fastest and simplest library for SQLite3 in Node.js.
