    GraphQL.js

    GraphQL.js

    A reference implementation of GraphQL for JavaScript

    ...This works because GraphQL.js is distributed with both CommonJS (require()) and ESModule (import) files. Ensure that any custom build configurations look for .mjs files! For practical applications, you'll probably want to run GraphQL queries from an API server, rather than executing GraphQL with a command line tool. GraphQL.js provides two important capabilities: building a type schema and serving queries against that type schema.

    QR Code generator library

    QR Code generator library

    High-quality QR Code generator library in Java, TypeScript/JavaScript

    ...The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library.

    EasyExcel

    EasyExcel

    Lightweight Java library developed by Alibaba for reading and writing

    ...It uses streaming/event-driven parsing to avoid loading entire workbooks into memory, and it maps rows to Java objects via simple annotations. Writers support multiple sheets, custom styles, merged cells, and template-based filling so production reports remain maintainable. The API emphasizes developer ergonomics: callbacks are straightforward, converters handle common type transformations, and header/column mapping is explicit. It integrates cleanly into Spring/enterprise stacks, often as part of import/export pipelines or scheduled report generation. By optimizing both performance and ease of use, EasyExcel reduces operational risk around big Excel jobs in web services and back-office tools.

    Official Android SDK for Stream Chat

    Official Android SDK for Stream Chat

    Android Chat SDK ➜ Stream Chat API. UI component libraries for chat

    This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. ...

    Kotlin Symbol Processing API

    ...The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects. Processors run as Gradle plugins, participate in incremental builds, and can target common use cases like DI bindings, JSON adapters, or UI glue code. Because the API reflects Kotlin semantics (nullability, visibility, type aliases, etc.), generated code aligns cleanly with Kotlin style and tooling.

    WordPress

    WordPress

    Just a mirror of the WordPress subversion repository

    ...It offers a flexible architecture of themes and plugins, where users can extend functionality or customize layout without touching core code. The administrative dashboard includes post and page editors, media library, user roles, plugin/theme installation, and site settings. Through its REST API and headless mode, WordPress also serves as a backend for decoupled front ends using frameworks like React, Vue, or Gatsby. Its maturity means a vast ecosystem of third-party integrations—SEO tools, forms, e-commerce, analytics—are available and battle-tested. Internally, WordPress handles routing, query parsing, template resolution, caching, and security hardening so developers can focus on content and user experience rather than infrastructure plumbing.

    A store locator plugin using Google Maps API version 3

    This jQuery plugin takes advantage of Google Maps API version 3 to create an easy to implement store locator. No back-end programming is required, you just need to feed it KML, XML, or JSON data with all the location information. How you create the data file is up to you. I originally created this for a company that didn’t have many locations, so I just used a static XML file. You will need to geocode your locations beforehand or use a geocoding API service if you want to try to do it on the fly. ...
