A JavaScript client library for connecting to Meteor backends from any JS environment, enabling real-time APIs without Meteor's front-end.
Asteroid is an isomorphic JavaScript client library that connects any JavaScript application to a Meteor backend. It enables real-time data synchronization and server-side method calls via the Distributed Data Protocol (DDP), without requiring Meteor's build system or front-end framework. This allows developers to use Meteor as a backend while maintaining flexibility in their front-end tooling.
JavaScript developers building applications that need real-time data from a Meteor backend but want to use alternative front-end frameworks like React, Vue, Angular, or vanilla JavaScript, or tools like webpack. It's also suitable for developers creating browser extensions, React Native apps, or admin interfaces connected to Meteor servers.
Developers choose Asteroid over Meteor's canonical front-end for its small footprint, framework-agnostic design, and ability to connect to multiple Meteor servers simultaneously. It provides a promise-based API and extensible mixins, allowing integration into existing projects without the constraints of Meteor's ecosystem.
An alternative client for a Meteor backend
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Works with any front-end framework like React, Vue, or vanilla JavaScript, as stated in the README, allowing integration into existing projects without framework lock-in.
Subscribes to Meteor publications and receives updates via DDP, enabling live data synchronization without manual polling, ideal for dynamic applications.
Can connect to multiple Meteor servers simultaneously, a feature highlighted in the README as perfect for admin interfaces or multi-tenant apps.
Enhances functionality through built-in or third-party mixins for login, subscriptions, and methods, providing modular customization and easy upgrades.
Uses promises for server method calls, as shown in the usage examples, making asynchronous code cleaner and more manageable compared to callbacks.
Requires specifying WebSocket endpoints and handling different SocketConstructors for various environments, adding initial configuration complexity beyond plug-and-play solutions.
Only useful with a Meteor backend, limiting its applicability compared to more general real-time libraries like Socket.IO, which work with any server.
Password login mixin does not hash passwords before transmission, as admitted in the README, relying solely on SSL, which might not meet all security standards.
Third-party mixins are limited, with only a few listed in the README, reducing out-of-the-box functionality and community support compared to richer libraries.
