    Middy

    Middy

    The stylish Node.js middleware engine for AWS Lambda

    ...If you have used web frameworks like Express, then you will be familiar with the concepts adopted in Middy and you will be able to get started very quickly. A middleware engine allows you to focus on the strict business logic of your Lambda and then attach additional common elements like authentication, authorization, validation, serialization, etc. in a modular and reusable way by decorating the main business logic. One of the main strengths of serverless and AWS Lambda is that, from a developer perspective, your focus is mostly shifted toward implementing business logic. ...

    ZXingLite

    ZXingLite

    Simplified version of ZXing, optimized to scan codes to generate QR

    ...By inheriting CaptureActivity or CaptureFragment and customizing the layout. (Applicable to most scenarios, and you don’t need to care about the code scanning related logic, you need to override the getLayoutId method when customizing the layout) Implementation examples: CustomCaptureActivity and QRCodeActivity. Instantiate a CameraScan in the Activity or Fragment of your project. (Applicable to use when you want to write interactive logic on the code scanning interface, and cannot directly or indirectly inherit CaptureActivity or CaptureFragment due to project architecture or other reasons)

    OpenFortiVPN

    OpenFortiVPN

    Client for PPP+TLS VPN tunnel services

    ...The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. Because it works with the standard tun interface, it integrates smoothly with common Linux networking stacks and pairs well with desktop frontends such as NetworkManager plugins. For admins and developers, it’s a scriptable, cross-platform-friendly alternative that makes FortiGate access reliable on servers and developer workstations alike.

    Small event-delegation library for decoupling event binding and handli

    Maxun named JsAction by Google serves as a lightweight event delegation library built in JavaScript. It allows developers to separate the logic of binding events from the code that handles those events, helping to keep DOM event wiring cleaner and more maintainable. It is archived and marked as read-only, indicating that the project is no longer actively maintained or intended for production use. The README states that ongoing development has migrated into a larger framework under the Angular project. ...

    Jackett

    Jackett

    API Support for your favorite torrent trackers

    Jackett works as a proxy server, it translates queries from apps (Sonarr, Radarr, SickRage, CouchPotato, Mylar3, Lidarr, DuckieTV, qBittorrent, Nefarious, etc.) into tracker-site-specific HTTP queries, parses the HTML or JSON response, and then sends results back to the requesting software. This allows for getting recent uploads (like RSS) and performing searches. Jackett is a single repository of maintained indexer scraping & translation logic, removing the burden from other apps. Trackers marked with (invite needed) have no active maintainer and may be missing features or be broken. If your client supports multiple feeds it's recommended to add each indexer directly instead of using all indexers. Using the all indexer has no advantages (besides reduced management overhead). ...

Our powerful plugin system allows you to add custom logic to the request's lifecycle. This package also provides a synchronous HttpClient interface with the same method signature as the PSR-18 client. For synchronous requests, we recommend using PSR-18 directly.

    Cerebral

    Cerebral

    Declarative state and side effects management for popular JavaScript

    ...When you make a code change you should create a branch first. When the code is changed and backed up by a test you can commit it from the root. A declarative approach to application logic also allows us to build developer tools that builds the mental image of this complexity for you. It makes perfect sense for us to write our UIs with declarative code. The reason is that we need to reuse UI elements and compose them together in different configurations. UIs are complex. But what about our application logic? Applications are becoming more complex in nature as we push the boundaries of user experiences.

    Extism

    The Universal Plug-in System. Extend anything with WebAssembly

    ...We support several environments through our official Host SDKs, and are adding more language support all the time. A plug-in system is software that enables your users or customers to add some logic into certain points in your application. You decide where this logic runs, and your users decide what the plug-in does. Many engineering teams face an ever-growing list of feature requests, often exceeding their bandwidth several times over. How can you ever keep up? Making your product extensible by its end-users is a great way to move some of those features outside the core, and empower customers to make your software more useful for them.

    PostgREST

    PostgREST

    REST API for any Postgres database

    ...The structural constraints and permissions in the database determine the API endpoints and operations. Using PostgREST is an alternative to manual CRUD programming. Custom API servers suffer problems. Writing business logic often duplicates, ignores or hobbles database structure. Object-relational mapping is a leaky abstraction leading to slow imperative code. The PostgREST philosophy establishes a single declarative source of truth: the data itself. It’s easier to ask PostgreSQL to join data for you and let its query planner figure out the details than to loop through rows yourself. ...

    TiddlyWiki

    TiddlyWiki

    A self-contained JavaScript wiki for the browser, Node.js, AWS Lambda

    TiddlyWiki5 is a mature, self-contained open-source personal wiki application and non-linear notebook implemented entirely in JavaScript that runs in the browser or a Node.js environment, letting users create, organize, and interlink small pieces of content called tiddlers without the need for a server backend or traditional hierarchical pages. Its entire application — including content, interface, and logic — can live in a single HTML file that users open and edit directly in a web browser, making it portable, offline-capable, and easy to share or archive without dependencies. Beyond its single-file form, TiddlyWiki5 can also run as a more traditional application via Node.js, enabling filesystem storage and plugin ecosystems to extend capabilities like rendering engines, themes, and automation tools.

    Immutable.js

    Immutable collections for JavaScript

    ...Immutable data is unchangeable once created, which makes application development so much simpler. There’s no defensive copying, and you get advanced memoization and change detection techniques with simple logic. Persistent data gives you a mutative API, one that doesn’t update data in-place but always produces new and updated data. The data structures that Immutable.js provides include List, Stack, Map, OrderedMap, Set and more. These structures are highly efficient on modern JavaScript VMs, and minimize the need to cache or copy data.
