    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. This ultimately became the underpinning for Facebook's GraphQL server implementation and type definitions. DataLoader is a simplified version of this original idea implemented in JavaScript for Node.js services. DataLoader is often used when implementing a graphql-js service, though it is also broadly useful in other situations.

    Deep Research

    Deep Research

    Use any LLMs (Large Language Models) for Deep Research

    Deep Research is a local-first research agent that orchestrates multiple LLMs to generate in-depth reports in minutes. It combines “thinking” and “task” model roles with live internet access to plan, search, read, and synthesize findings into structured outputs. The project emphasizes privacy: processing and storage happen locally, avoiding server-side retention of your queries and notes. A simple web UI lets you enter topics and configure models, while the backend streams progress as sources are fetched and arguments are weighed. It offers MCP server support and SSE APIs, so IDEs and agent clients can drive the same workflow programmatically. The result is a repeatable process for scoping questions, collecting evidence, and producing a concise report with citations and reasoning steps.

    EJS

    EJS

    Embedded JavaScript templates for node

    EJS is a templating engine for JavaScript/Node.js that allows developers to embed plain JavaScript code into HTML markup. The idea is to avoid introducing a separate DSL for templating and instead use familiar JavaScript logic inside template tags to generate dynamic content. You write templates using <% %> scriptlet tags, <%= %> for output, and you can include other templates, pass data, and control flow with loops and conditionals. It’s fast because it compiles templates to JavaScript functions and caches them by default, so subsequent rendering is efficient. EJS supports both server-side render (in Node/Express) and client-side use in the browser, making it versatile for universal apps. Because you’re using raw JS, debugging is simple—the errors are standard JS stack traces with template line numbers included. While it doesn’t impose a rigid structure (you’re free to organize templates however you like), it works reliably and is simple to adopt.

    Elymus

    Elymus

    Decentralized stack for paranoids-decentralizers

    Elymus is stack for dWeb: Browser, SDK, and bundle of nodes for p2p communication. It uses Repens protocol for dWeb sites (however you can access usual web2 sites through it, better use normal browser when doing it), developed to provide absolutely decentralized way to host and access frontends. Repens protocol utilizes Handshake Protocol as decentralized KV storage and content addressing system, IPFS as p2p caching system (user visits site, and caches its content, while seeding it through p2p network to next visitors, just like torrent but for websites), and Arweave/Sia/Hypercore Protocol as content anchoring networks (that will seed frontend when nobody has it in IPFS cache). Elymus is driven by decentralization-first convenience-last ideology. We have already seen many dWeb projects whose only relation to dWeb is that they utilize blockchains in some way. So we are ready to pay with convenience and heaviness for decentralization.

    Exifr

    Exifr

    The fastest and most versatile JS EXIF reading library

    Exifr is a fast and very versatile JavaScript EXIF reading library that works everywhere, parses everything and handles just about anything you throw at it. It can handle any input: buffers, url, <img> tag and more; .jpg, .tif, and .heic files; and TIFF (EXIF, GPS, etc.), XMP, ICC, IPTC, JFIF segments. It skips parsing tags you don’t need, and reads only the first few bytes. There’s no need to read the whole file to see if there’s an EXIF file in it, or extract all the data when you just need a few tags. Instead of reading byte by byte from start to finish, Exifr jumps through the file structure from pointer to pointer, making it extremely fast and efficient!

    Fetch JSONP

    Fetch JSONP

    Make JSONP request like window.fetch

    Fetch JSONP is a small JavaScript library that provides a Fetch-like API for JSONP requests. Standard Fetch does not support JSONP, so this package fills that specific compatibility gap. Developers can call fetchJsonp, receive a promise, and parse the response with a familiar .json() flow. The library supports custom callback parameter names, custom callback function names, and request timeouts. It also documents the difference between regular JSON APIs and JSONP endpoints, which helps avoid common syntax errors. fetch-jsonp is useful for legacy APIs, older cross-domain integrations, and browser applications that still need JSONP behavior.
