    DataLoader

    DataLoader

    Generic utility to use with an application's data fetching layer

    DataLoader is a generic utility to be used as part of your application's data fetching layer to provide a simplified and consistent API over various remote data sources such as databases or web services via batching and caching. A port of the "Loader" API originally developed by @schrockn at Facebook in 2010 as a simplifying force to coalesce the sundry key-value store back-end APIs which existed at the time. At Facebook, "Loader" became one of the implementation details of the "Ent" framework, a privacy-aware data entity loading and caching layer within web server product code. ...

    Roaring bitmaps in Go (golang)

    ...We have a format specification. Sets are a fundamental abstraction in software. They can be implemented in various ways, as hash sets, as trees, and so forth. In databases and search engines, sets are often an integral part of indexes. For example, we may need to maintain a set of all documents or rows (represented by numerical identifiers) that satisfy some property. Besides adding or removing elements from the set, we need fast functions to compute the intersection, the union, the difference between sets, and so on. ...

    Gradle JOOQ Plugin

    Gradle JOOQ Plugin

    Gradle plugin that integrates jOOQ

    ...It wires jOOQ’s code generator into the Gradle build lifecycle, so whenever the schema changes, developers can regenerate matching Java classes directly through a Gradle task. The plugin handles dependencies, classpaths, and configuration options for connecting to different databases. It supports customization of generator options, such as output directories, package names, and which tables or schemas to include. By automating schema-to-code generation, the plugin keeps the application’s data model and database in sync. This reduces runtime errors and increases productivity by making database interactions strongly typed and integrated into the development workflow.

    Node.js Testing Best Practices

    Beyond the basics of Node.js testing

    ...The material explains how to structure tests around process boundaries—HTTP, queues, cron jobs—while keeping fast feedback cycles through selective integration tests and reliable test doubles. It dives into topics like test containers, ephemeral databases, and idempotent fixtures to ensure deterministic runs in CI. Observability is treated as part of testing: logs, metrics, and tracing make failures diagnosable instead of mysterious. By aligning tests with service responsibilities instead of internal modules, the guide helps teams produce suites that reflect real production behavior.

    Dexie.js

    Dexie.js

    A Minimalistic Wrapper for IndexedDB

    ...Dexie is thoroughly explained, and examples are available to help you on your way. Dexie has near-native performance. Its bulk operations utilize an often-overlooked feature in IndexedDB, ignoring success callbacks when possible. Offline databases are groovy! But without keeping the database in sync with a server, you're missing a great deal. Dexie.js solves these limitations and provides a neat database API. Dexie.js aims to be the first-hand choice of a IDB Wrapper Library due to its well thought-through API design, robust error handling, extendability, change tracking awareness and its extended KeyRange support (case insensitive search, set matches and or operations).

    The Apache Struts web framework

    Mirror of Apache Struts

    ...Web applications differ from conventional websites in that web applications can create a dynamic response. Many websites deliver only static pages. A web application can interact with databases and business logic engines to customize a response. Web applications based on JavaServer Pages sometimes commingle database code, page design code, and control flow code. In practice, we find that unless these concerns are separated, larger applications become difficult to maintain. One way to separate concerns in a software application is to use a Model-View-Controller (MVC) architecture. ...
