Apollo Server's standalone server lets you get a GraphQL server up and running quickly without needing to set up an HTTP server yourself.

GraphQL WebSocket
Coherent, zero-dependency, lazy, simple, GraphQL
Coherent, zero-dependency, lazy, simple, GraphQL over WebSocket Protocol compliant server and client. Messages are represented through the JSON structure and are stringified before being sent over the network.

Connection is a connection within the established socket describing a "connection" through which the operation requests will be communicated. The server can close the socket (kick the client off) at any time. The close event dispatched by the server is used to describe the fatal error to the client. The client closes the socket and the connection by dispatching a 1000: Normal Closure close event to the server indicating a normal closure. -

express-validator
An express.js middleware for validator.js
express-validator is a set of express.js middlewares that wraps validator.js validator and sanitizer functions. It's recommended that you have basic knowledge of the express.js module before you go on with this guide. Sometimes, receiving input in a HTTP request isn't only about making sure that the data is in the right format, but also that it is free of noise. validator.js provides a handful of sanitizers that can be used to take care of the data that comes in. Although express-validator offers plenty of handy validators and sanitizers through its underlying dependency validator.js, it doesn't always suffice when building your application. For these cases, you may consider writing a custom validator or a custom sanitizer. A custom validator may be implemented by using the chain method .custom(). It takes a validator function. -

JSON-Studio
Fast, private desktop app to explore, search, query and diff files
JSON Studio is a private, lossless workspace for JSON. Most JSON tools either choke on big files, silently mangle your numbers, or send your data to a server. JSON Studio does none of that.

Everything runs on your own machine - no accounts, no uploads, no analytics, no network calls - making it safe for proprietary, regulated or personal data.
