Nymph.js

JavaScript data objects for Node.js and the browser.

Nymph is an object relational mapper for collaborative web apps. Nymph runs in Node.js and provides a REST server with a client that works in Node.js and the browser. It allows rapid prototyping and production ready speed and features.

Nymph can use SQLite3, MySQL, or PostgreSQL as its database backend. You can use SQLite in development, and MySQL or Postgres in production. You can even use Nymph with SQLite in an Electron app.

Features

Write simple JSON search queries, with automatic access control built right in, and get updated on the client automatically with any changes. You can have all your logic on the frontend, or the backend if you prefer, because you work with the data all the same.

Speedy

Nymph is fast. Not just in processing, but Nymph can be used for rapid prototyping.

Secure

Nymph provides an optional user and group manager called Tilmeld that secures your app based on granular permission controls.

Reactive

Nymph's publish/subscribe server makes it easy to build collaborative apps. Subscribe to queries from the client and be updated when the queries' results have changed.

Atomic Transactions

Nymph supports atomic, nested transactions to ensure data integrity. Nothing is actually written to the database until the top level transaction is committed.

Full Text Search

Nymph provides a full text search engine to provide fast results when searching through millions of entities.

Open Source

Nymph is licensed under the Apache-2 license. It provides all you need to build a backend for your app and the frontend tools you'll need as well.

Framework Agnostic

Nymph is very easy to integrate into React, Svelte, Angular, Ember, and more.

Nymph's easy querying on the server and client makes it perfect for building complex apps with any frontend framework. Because you don't have to write SQL, almost all of your logic can be on the client side, if you prefer. You can also use backend logic in the client as if it were written on the front-end with automatic asynchronous server calls.

Nymph's REST server package makes it easy to integrate anywhere in your app. It provides an Express middleware that you can place on any arbitrary endpoint.

Nymph's PubSub server package makes synchronizing your client with pushed changes from the server super easy. With a reactive framework on the frontend, your UI will update in near real time to changes to any entities that match your subscribed queries.
