    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 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.

    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.

    MSON

    MSON

    Generate an app from JSON

    The MSON compiler allows you to generate apps from JSON. The ultimate goal of MSON is to allow anyone to develop software visually, but you can also use pieces of MSON to turbo charge your development. MSON is a subset of JSON and comprised of just a few building blocks, yet it is as powerful as its non-declarative counterparts. MSON supports validation, inheritance, composition, pub/sub, access control, templating and various other features. MSON is particularly useful in software that generates other software, e.g. a form builder. This is because MSON is just JSON, so it is easy to consume, modify and store. MSON is framework agnostic, but the default mson-react rendering layer uses React and Material-UI to generate a UI. The rendering layer is pluggable and can be written to support any framework and UI library. The MSON library can also be used without any UI dependecies, which makes it great for things like data validation in both the front and back ends.
