JSON Server
Get a full fake REST API with zero coding
Get a full fake REST API with zero coding in less than 30 seconds (seriously). Created with <3 for front-end developers who need a quick back-end for prototyping and mocking. If you need to add authentication, validation, or any behavior, you can use the project as a module in combination with other Express middleware. You can deploy JSON Server. For example, JSONPlaceholder is an online fake API powered by JSON Server and running on Heroku. If you make POST, PUT, PATCH or DELETE requests, changes will be automatically and safely saved to db.json using lowdb. You can use JSON Server to serve your HTML, JS and CSS, simply create a ./public directory or use --static to set a different static files directory. There are many ways to set up SSL in development. One simple way is to use hotel. -

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. -

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. -

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. -

jul-javascript
JUL - The JavaScript UI Language
The JavaScript UI Language (JUL) is a configuration and instantiation module for the JavaScript frameworks. It can be used with any framework that accepts a configuration object as a constructor parameter, or with a custom factory for the other frameworks. JUL parses a tree of configuration objects, and creates the runtime components in the expected order and membership. For the most uses, after this step, you will have your application's user interface up and running. Browser support: JUL supports all major browsers, including: FF 2+, IE 7+, Edge, Safari 3+, Chrome 1+, Opera 9+, IOS 3+, Android 2+. -
