Ejs
ejs est un moteur de template JavaScript embarqué pour Node.js qui génère du HTML et d'autres formats textuels en intégrant de la logique JavaScript dans les templates. Il fonctionne comme un moteur de rendu côté serveur et un processeur de template HTML qui fusionne le balisage statique avec des données dynamiques.
Le système opère comme une bibliothèque de templates compilés, convertissant les templates en fonctions JavaScript pour permettre un rendu mis en cache et une exécution plus rapide. Il inclut une sécurité intégrée pour prévenir les attaques XSS en échappant automatiquement les entités HTML et les caractères spéciaux durant le processus de rendu.
Le moteur supporte une conception modulaire via l'utilisation de templates partiels, permettant l'insertion de composants d'interface réutilisables dans des structures de page plus larges. Il offre également la possibilité de définir des délimiteurs personnalisés pour éviter les conflits de syntaxe au sein des documents.
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.
