    DefiantJS

    DefiantJS

    Provides the ability for you to build smart templates applications

    Do you need to query large JSON structures? Do you end up coding loops to parse the JSON and identify the data that matches your query? Defiant offers a better way. Defiant extends the global JSON object with a "search" method that enables lightning-fast searches using XPath expressions. Try out the XPath Evaluator to get the idea. DefiantJS provides the ability for you to build smart templates applicable on JSON structures, based upon proven & standardized technologies such as XSLT and XPath. As of v2.0.0, Defiant can be utilized in the Node.js environment. Since there is no default support for XML technologies in Node, the library puppeteer is initiated to mimic the browser environment, with Defiant running. All methods called from Node is piped via Puppeteer. Even though, Defiant now can be used in the Node environment - utilizing Defiant in the browser is recommended. It all boils down to whether you want your servers to run thousands of searches for your clients.

    Extended Memory Semantics (EMS)

    Extended Memory Semantics (EMS)

    Persistent shared object memory and parallelism for Node.js and Python

    EMS makes possible persistent shared memory parallelism between Node.js, Python, and C/C++. Extended Memory Semantics (EMS) unifies synchronization and storage primitives to address several challenges of parallel programming. A modern multi-core server has 16-32 cores and nearly 1TB of memory, equivalent to an entire rack of systems from a few years ago. As a consequence, jobs formerly requiring a Map-Reduce cluster can now be performed entirely in shared memory on a single server without using distributed programming.

    Himalaya

    Himalaya

    JavaScript HTML to JSON Parser

    Parse HTML into JSON. Himalaya bundles well with Browersify and Webpack. Himalaya transforms HTML into JSON, that's it. Himalaya is synchronous and does not require any complicated callbacks. Himalaya does not cut corners and returns an accurate representation of the HTML supplied. To remove whitespace, post-process the JSON; check out an example script. Himalaya can include the start and end positions of nodes in the parse output. To enable this, you can pass parse the parseDefaults extended with includePositions: true. Himalaya provides a stringify method. The following example parses the HTML to JSON then parses the JSON back into HTML.

    JSON Editor

    JSON Editor

    A web-based tool to view, edit, format, and validate JSON

    JSON Editor is a web-based JSON editing and visualization tool designed for viewing, editing, formatting, validating, and transforming JSON documents in multiple interactive modes. The project provides several editing interfaces including tree view, code editor, form-based editing, and plain text modes, allowing users to work with structured data in the format most suitable for their workflow. It can be embedded directly into web applications as a reusable component and supports large JSON documents with schema validation and formatting capabilities. JSONEditor emphasizes usability by combining developer-focused functionality with accessible visual editing tools for non-technical users. The library supports modern browser environments and integrates with JavaScript module systems for flexible deployment. Its versatility has made it a popular solution for API debugging, configuration management, data inspection, and administrative interfaces.

    JSON Form

    JSON Form

    Build forms from JSON Schema, easily template-able

    The JSON Form library is a JavaScript client-side library that takes a structured data model defined using JSON Schema as input and returns a Bootstrap 3-friendly HTML form that matches the schema. The generated HTML form includes client-side validation logic that provides direct inline feedback to the user upon form submission (provided a JSON Schema validator is available). If values are valid, the JSON Form library uses submitted values to create the JavaScript data structure that matches the data model. The layout of the generated HTML form may be entirely fine-tuned through a simple declarative mechanism. If you're more of the acting type than of the reading type, the JSON Form Playground is a simple JSON Form editor that lets you try out and extend all the examples in the doc.

    JSON Splora

    JSON Splora

    GUI app for editing, visualizing, and manipulating JSON data

    JSON-Splora is a GUI for editing, visualizing, and manipulating JSON data with jq or JavaScript. The editor is a JavaScript editor, and the input is parsed as json5. This allows for comments as well as a relaxed JSON input format. Once the editor has valid JSON, an input window will appear below, allowing you to manipulate the object with JavaScript or jq. A panel will appear to the right with the output, and updates live as the input or filter changes.

    JSON5

    JSON5

    JSON5 — JSON for Humans

    JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. JSON5 was started in 2012, and as of 2022, now gets >65M downloads/week, ranks in the top 0.1% of the most depended-upon packages on npm, and has been adopted by major projects like Chromium, Next.js, Babel, Retool, WebStorm, and more. It's also natively supported on Apple platforms like MacOS and iOS. Formally, the JSON5 Data Interchange Format is a superset of JSON (so valid JSON files will always be valid JSON5 files) that expands its syntax to include some productions from ECMAScript 5.1 (ES5). It's also a subset of ES5, so valid JSON5 files will always be valid ES5. This JavaScript library is a reference implementation for JSON5 parsing and serialization and is directly used in many of the popular projects mentioned above.

    JSON:API

    JSON:API

    A specification for building JSON APIs

    This repository defines the specification for JSON:API, a standardized format for building APIs with JSON. The goal is to minimize bikeshedding and inconsistency by giving developers a well-documented schema for requests and responses. It specifies how to represent resources, relationships, pagination, sorting, filtering, and metadata in a predictable way. Clients and servers that follow the spec can interoperate seamlessly without custom glue code for every new service. JSON:API also emphasizes efficiency, recommending ways to reduce payload size and minimize the number of requests. Over time it has become a widely adopted contract for RESTful APIs, helping teams save time and avoid fragmentation across microservices and third-party integrations.

    JSONPlaceholder

    JSONPlaceholder

    A simple online fake REST API server

    JSONPlaceholder is a free, fake online REST API designed for prototyping, tutorials, and UI demos without standing up a real backend. It provides predictable endpoints for resources like posts, comments, albums, photos, todos, and users with realistic data shapes. Because the data is publicly available and stable, you can build fetch logic, paginate, and render lists while focusing on front-end patterns rather than server plumbing. The API accepts typical HTTP verbs and returns JSON in a consistent format, making it easy to swap with a real server later. It’s widely used in examples, workshops, and automated tests where a dependable dummy service accelerates iteration. With zero setup, it removes a major friction point for learning HTTP clients and front-end data flows.
