Ejs
ejs es un motor de plantillas JavaScript embebido para Node.js que genera HTML y otros formatos de texto mediante la inserción de lógica JavaScript en plantillas. Funciona como un motor de renderizado del lado del servidor y procesador de plantillas HTML que combina marcado estático con datos dinámicos.
El sistema opera como una librería de plantillas compiladas, convirtiendo las plantillas en funciones JavaScript para permitir el renderizado en caché y una ejecución más rápida. Incluye seguridad integrada para prevenir ataques de cross-site scripting (XSS) mediante el escape automático de entidades HTML y caracteres especiales durante el proceso de renderizado.
El motor soporta un diseño modular mediante el uso de plantillas parciales, permitiendo la inserción de componentes de interfaz reutilizables en estructuras de página más grandes. También proporciona la capacidad de definir delimitadores personalizados para evitar conflictos de sintaxis dentro de los documentos.
Features
- Server-Side Dynamic Page Generation - Functions as a server-side engine that merges JavaScript data with templates to instantiate dynamic web pages.
- HTML Content Renderers - Generates HTML output by combining dynamic data with reusable layouts and modular components.
- Template-Based Code Generators - Converts template syntax into executable JavaScript functions to generate final rendered strings.
- Template Compilation - Converts template strings into executable JavaScript functions to enable high-performance interpolation and cached execution.
- HTML Entity Escaping - Automatically transforms dynamic data into safe HTML entities to prevent cross-site scripting attacks.
- Output Escaping - Provides automatic encoding of dynamic data into safe formats to prevent cross-site scripting attacks during HTML rendering.
- Reusable Template Fragments - Enables the use of shareable template fragments across multiple layouts to reduce redundancy.
- Escaping Utilities - Automatically encodes dynamic text content to prevent malicious script injection and XSS.
- HTML Template Renderers - Merges data dictionaries with predefined templates to generate final HTML strings for browser rendering.
- Reusable Components - Supports the use of partial templates to create modular, reusable interface components within larger layouts.
- Partial Templates - Supports reusable template fragments that can be nested and resolved by name at runtime.
- Secure Renderers - Prevents cross-site scripting by automatically escaping special characters when rendering data into HTML.
- JavaScript Template Engines - Provides a JavaScript template engine for Node.js that transforms template strings into executable functions for text generation.
- Server-Side Rendering - Transforms dynamic data and logic into static HTML strings on the server before sending them to the client.
- Template Data Merging - Combines compiled templates from the filesystem with data objects to produce a final output string.
- Data Transformation Filters - Allows transforming data using formatting modifiers before rendering the final content.
- Template Caches - Implements in-memory caching of precompiled template functions to increase rendering speed and reduce CPU overhead.
- Template Compilation Caches - Stores precompiled JavaScript functions in memory to increase rendering speed for repeated requests.
- Compiled Caches - Stores templates compiled into executable code in memory to avoid redundant parsing.
- Precompiled Template Execution - Converts templates into standalone JavaScript functions for faster execution by removing the need for repeated parsing.
- Automatic Template Escaping - Automatically encodes dynamic values in templates to prevent script injection during HTML processing.
- Recursive Template Resolution - Resolves nested template fragments by recursively executing associated functions until a final string is produced.
- Template Expression Parsing - Uses regular expressions to identify embedded logic and static text within template strings.
- Data Transformation Filters - Provides functions within templates to transform raw data into specific formats before output.
- Node.js Frameworks and Tools - Embedded JavaScript template engine.
