Ejs
ejs ist eine eingebettete JavaScript-Template-Engine für Node.js, die HTML und andere Textformate durch das Einbetten von JavaScript-Logik in Templates generiert. Sie fungiert als Server-Side-Rendering-Engine und HTML-Template-Prozessor, der statisches Markup mit dynamischen Daten zusammenführt.
Das System arbeitet als kompilierte Template-Bibliothek, die Templates in JavaScript-Funktionen umwandelt, um gecachtes Rendering und schnellere Ausführung zu ermöglichen. Es enthält integrierte Sicherheitsfunktionen, um Cross-Site-Scripting zu verhindern, indem HTML-Entitäten und Sonderzeichen während des Rendering-Prozesses automatisch maskiert werden.
Die Engine unterstützt modulares Design durch die Verwendung von Partial-Templates, was das Einfügen wiederverwendbarer Interface-Komponenten in größere Seitenstrukturen ermöglicht. Zudem bietet sie die Möglichkeit, benutzerdefinierte Trennzeichen zu definieren, um Syntaxkonflikte innerhalb von Dokumenten zu vermeiden.
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.
