{"id":12882,"library":"betajs-server","title":"BetaJS Server-Side Framework","description":"BetaJS-Server is a server-side JavaScript framework extension for the core BetaJS library, providing backend functionalities for applications. It offers capabilities such as database access and persistent storage with explicit support for MongoDB, server-side AJAX request handling, and robust session management. The current stable version is 1.0.29, and while a specific release cadence isn't stated, the version numbering suggests a mature, but potentially slowly evolving project. Its key differentiators include its tight integration with the broader BetaJS ecosystem and its direct provision of common backend patterns like MongoDB interaction and session management, making it suitable for projects already leveraging BetaJS on the frontend or for full-stack JavaScript applications built entirely within the BetaJS paradigm. It explicitly supports NodeJS versions 4.0 up to the latest, indicating ongoing compatibility efforts.","status":"maintenance","version":"1.0.29","language":"javascript","source_language":"en","source_url":"git://github.com/betajs/betajs-server","tags":["javascript"],"install":[{"cmd":"npm install betajs-server","lang":"bash","label":"npm"},{"cmd":"yarn add betajs-server","lang":"bash","label":"yarn"},{"cmd":"pnpm add betajs-server","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Core framework dependency, providing fundamental utilities and structures that betajs-server extends.","package":"betajs","optional":false},{"reason":"Provides data handling and persistence capabilities, essential for the database and store features in betajs-server.","package":"betajs-data","optional":false}],"imports":[{"note":"BetaJS-Server and its dependencies are distributed as CommonJS modules, often requiring specific paths like 'dist/beta.js'.
