:::

Meteor is a full-stack JavaScript platform for developing modern web and mobile applications. Meteor includes a key set of technologies for building connected-client reactive applications, a build tool, and a curated set of packages from the Node.js and general JavaScript community.

- Meteor allows you to develop in **one language**, JavaScript or TypeScript, in all environments: application server, web browser, and mobile device.

- Meteor uses **data on the wire**, meaning the server sends data, not HTML, and the client renders it.

- Meteor **embraces the ecosystem**, bringing the best parts of the extremely active JavaScript community to you in a careful and considered way.

- Meteor provides **full stack reactivity**, allowing your UI to seamlessly reflect the true state of the world with minimal development effort.

- Meteor offers **flexibility in front-end** development, allowing you to choose your preferred framework such as React, Vue, Blaze, Svelte, or Solid.

- Meteor **simplifies back-end and front-end integration** through Methods, its built-in Remote Procedure Call (RPC) system for seamless communication.

- Meteor includes a **ready-to-use Login and Accounts** package, eliminating the need to rebuild authentication systems for your applications.
