Assetic
Assetic is a frontend build tool and asset pipeline manager for PHP applications. It functions as a static asset optimizer and compiler that transforms, organizes, and exports CSS and JavaScript files to disk for service by a web server.
The system uses a filter-based transformation pipeline to convert preprocessor languages into standard web formats and minify code for production environments. It incorporates a versioning system that assigns unique timestamps or identifiers to filenames to prevent browsers from loading outdated cached assets.
The tool manages static file bundling by merging multiple source files into single output bundles and utilizes dependency-graph tracking to ensure the correct loading sequence. It also supports the generation of multiple asset variants based on specific variables and employs a disk-backed compilation cache to avoid repetitive processing.
Features
- Asset Transformation Pipelines - Provides a modular architecture for processing and compiling CSS and JavaScript through a sequence of filters.
- Frontend Build Tools - Provides a comprehensive build tool to compile, bundle, and optimize web assets for PHP-based applications.
- Asset Bundlers - Combines static files from individual paths or directory patterns into a single output file.
- JavaScript and CSS Minifications - Compiles preprocessor languages into standard CSS and JavaScript and reduces file size through minification.
- Frontend Build Pipelines - Provides an automated sequence of tasks for bundling, minifying, and optimizing web assets for production.
- Cache Busting - Implements cache busting by appending modification timestamps to filenames to force browser updates.
- Asset Dependency Managers - Identifies imported files within assets to ensure they load in the correct sequence.
- Compilers - Compiles preprocessor languages into standard web formats and minifies code for production delivery.
- Asset Graph Mapping - Implements logic to analyze the dependency graph of assets to determine the correct loading sequence and prevent duplication.
- Frontend Asset Compilation - Transforms source preprocessors into browser-ready JavaScript and CSS files while applying minification.
- PHP Asset Pipelines - Manages the compilation, minification, and merging of frontend assets within the context of a PHP application.
- Static Asset Management - Organizes and serves static CSS and JavaScript files specifically tailored for PHP application environments.
- Static Asset Management - Provides tools to optimize website performance by compressing, minifying, and caching static files.
- Static Asset Optimizers - Processes source files through a series of filters to optimize load times and ensure correct asset sequencing.
- Transformed Asset Caches - Saves results of asset transformations to eliminate the need for repetitive filtering and compilation.
- Compilation Caches - Provides a disk-backed cache to store processed asset results and avoid repetitive compilation during requests.
- Asset Collections - Maps source files to target paths using organized sets to prevent file duplication.
- Content Transformation Pipelines - Runs files through a sequence of plugins to compile preprocessors and minify code.
- Asset Variants - Generates multiple versions of a single asset by applying different configuration variables at runtime.
- Static Asset Pipelines - Provides automated workflows to manage the processing, optimization, and delivery of static web assets.
- Module Bundling - Merges multiple source files and their dependencies into single output bundles to reduce HTTP requests.
- Asset Filename Hashing - Implements content-based filename hashing to manage browser caching and ensure fresh asset delivery.
- Production Asset Preparation - Processes development files through specialized filters to prepare them for production environments.
- Static Asset Exporters - Writes processed asset content to a designated directory for service by a web server.
- Path Pattern Resolution - Locates source files by mapping defined directories and file patterns to specific target output paths.
- Asset Versioning - Generates unique file identifiers to handle browser cache invalidation for stylesheets and scripts.
- Variable-Driven Generation - Creates multiple versions of an asset based on specific variables to deliver tailored code at runtime.
