  • Metabase

    The simplest, fastest way to get business intelligence and analytics to everyone in your company :yum:

    Project mention: My mental model of Clojure transducers | | 2023-09-10

    It seems folks want a working example. Here's one in prod:

    Metabase is a BI tool, backend written mostly in Clojure. Like basically all BI tools they have this intermediate representation language thing so you write the same thing in "MBQL (metabase query language)" and it theoretically becomes same query in like, Postgres and Mongo and whatever. End user does not usually write MBQL, it's a service for the frontend querybuilding UI thing and lots of other frontend UI stuff mainly in usage.

    Whole processing from MBQL -> your SQL or whatever is done via a buncha big-ass transducers. Metabase is not materially faster than other BI tools (because all the other BI tools do something vaguely similar in their langs) but it's pretty comparable speed and the whole thing was materially written by like 5 peeps

    (nb: I used to work for Metabase but currently do not. but open core is open core)

  • Prisma

    Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB

    Project mention: How To Manage Access and Refresh Tokens for an API in Next.js 13 With Supabase and Prisma | | 2023-09-22

    So, we will use Supabase as a Postgres database to store the tokens and Prisma as our ORM of choice to communicate with our database.

  • SheetJS js-xlsx

    📗 SheetJS Spreadsheet Data Toolkit -- New home

    Project mention: how to work with .xlsx files? | /r/node | 2023-06-28

    ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.

  • LevelDB

    LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.

    Project mention: Bloom filter support to leveldb by Sanjay Ghemawat | | 2023-08-02

    Project mention: ERDIA: TypeORM entity specification documentation tool | | 2023-08-28

    The image above is a chart comparing three popular ORM tools from the ERDIA only supports TypeORM for now, but the roadmap is to support Sequelize and Prisma as well.

  • SQLMap

    Automatic SQL injection and database takeover tool

    Project mention: Enhancing Code Quality and Security: Building a Rock-Solid CI Test Suite for Seamless Development | | 2023-07-03

    The DAST checks can be automated up to a certain point, where the code should be able to withstand certain scans and attacks. For eg. SQL Injections can be checked with sqlmap which tests with each and every type of sql injection payload and reports it back to the user.

  • cockroach

    CockroachDB - the open source, cloud-native distributed SQL database.

    Project mention: Is it bad to create a publicly accessible RDS database for my serverless web app? | /r/aws | 2023-08-11

    For example, when you create a serverless postgres database with a platform like CockroachDB or Neon, you effectively get a connection string with a strong password. Anyone can connect to your database from anywhere so long as they have the right connection string. There are no security settings in these services to change this behavior.

  • InfluxDB

    Scalable datastore for metrics, events, and real-time analytics

    Project mention: InfluxDB 3 is out, OSS commits have been tried up - is this the end? | /r/influxdb | 2023-05-10
  • RocksDB

    A library that provides an embeddable, persistent key-value store for fast storage.

    Project mention: In-memory vs. disk-based databases: Why do you need a larger than memory architecture? | | 2023-09-05

    The in-memory version of Memgraph uses Delta storage to support multi-version concurrency control (MVCC). However, for larger-than-memory storage, we decided to use the Optimistic Concurrency Control Protocol (OCC) since we assumed conflicts would rarely happen, and we could make use of RocksDB’s transactions without dealing with the custom layer of complexity like in the case of Delta storage.

  • Mongoose

    MongoDB object modeling designed to work in an asynchronous environment.

    Project mention: Mongoose Handbook | | 2023-09-08

    Mongoose is a popular JavaScript library used with MongoDB, a NoSQL database. It provides an elegant and user-friendly way to interact with MongoDB from Node.js applications. Mongoose offers several key benefits:

    Project mention: Building a User Feedback Widget with Vue.js and Directus | | 2023-09-21

    One of our DevRel initiatives at Directus is constantly improving our documentation. As a small team with finite time and resources, we rely a lot on user feedback to help guide our writing efforts. But we were missing the most important bit there – your feedback.

  • Milvus

    A cloud-native vector database, storage for next generation AI applications

    Project mention: Code Search with Vector Embeddings: A Transformer's Approach | | 2023-08-27

    As the size of the codebase grows, storing and searching through embeddings in memory becomes inefficient. This is where vector databases come into play. Tools like Milvus, Faiss, and others are designed to handle large-scale vector data and provide efficient similarity search capabilities. I've wrtten about how to also use sqlite to store vector embeddings. By integrating a vector database, you can scale your code search tool to handle much larger codebases without compromising on search speed.

  • surrealdb

    A scalable, distributed, collaborative, document-graph database, for the realtime web

    Project mention: How to Design a SurrealDB schema and create a basic client for TypeScript | | 2023-09-17
