UI5 Builder

The UI5 Builder module takes care of building your project.

Based on a project's type, the UI5 Builder defines a series of build steps to execute; these are also called "tasks".

For every type there is a set of default tasks. You can disable single tasks using the --exclude-task CLI parameter, and you can include tasks using the --include-task parameter.

API Reference

Types

Types define how a project can be configured and how it is built. A type orchestrates a set of tasks and defines the order in which they get applied during build phase. Furthermore, it takes care of formatting and validating the project-specific configuration.

Also see UI5 Project: Configuration

application

Projects of type application are typically the main or root project. In a projects dependency tree, there should only be one project of type application. If multiple are found, those further away from the root are ignored.

The source directory of an application (typically named webapp) is mapped to the virtual root path /.

An applications source directory may or may not contain a Component.js file. If it does, it must also contain a manifest.json file. If there is a Component.js file, an optimized Component-preload.js file will be generated during the build.

library

UI5 libraries are often referred to as reuse-, custom- or control libraries. They are a key component in sharing code across multiple projects in UI5.

A project of type library must have a source directory (typically named src). It may also feature a "test" directory. These directories are mapped to the virtual directories /resources for the sources and /test-resources for the test resources.

These directories should contain a directory structure representing the namespace of the library (e.g. src/my/first/library) to prevent name clashes between the resources of different libraries.

theme-library

Available since Specification Version 1.1

UI5 theme libraries provide theming resources for the controls of one or multiple libraries.

A project of type theme-library must have a source directory (typically named src). It may also feature a "test" directory. These directories are mapped to the virtual directories /resources for the sources and /test-resources for the test resources.

The source directory must contain a directory structure representing the namespaces of the libraries it provides theme resources for. For example, a theme library named my_custom_theme, providing resources for a library named my.library should have these resources in a directory path my/library/themes/my_custom_theme/.

module

The module type is meant for usage with non-UI5 resources like third party libraries. Their path mapping can be configured freely. During a build, their resources are copied without modifications.

Tasks

Tasks are specific build steps to be executed during build phase.

They are responsible for collecting resources which can be modified by a processor. A task configures one or more processors and supplies them with the collected resources. After the respective processor processed the resources, the task is able to continue with its workflow.

A project can add custom tasks to the build by using the Custom Tasks Extensibility.

Standard Tasks

All available standard tasks are documented in the API reference and are listed below in the order of their execution:

Task Type application Type library Type theme-library
escapeNonAsciiCharacters enabled enabled
replaceCopyright enabled enabled enabled
replaceVersion enabled enabled enabled
replaceBuildtime enabled
generateJsdoc disabled 1
executeJsdocSdkTransformation disabled 1
generateFlexChangesBundle enabled
generateManifestBundle disabled disabled
generateLibraryManifest enabled
generateComponentPreload enabled disabled 2
generateLibraryPreload enabled
generateStandaloneAppBundle disabled 3
transformBootstrapHtml disabled 3
generateBundle disabled 4 disabled 4
buildThemes enabled enabled
generateThemeDesignerResources disabled disabled
createDebugFiles enabled enabled
uglify enabled enabled
generateVersionInfo enabled
generateCachebusterInfo disabled
generateApiIndex disabled 1
generateResourcesJson disabled disabled disabled

Disabled tasks can be activated by certain build modes, the project configuration, or by using the --include-task CLI parameter. See footnotes where given


1 Enabled in jsdoc build, which disables most of the other tasks
2 Enabled for projects defining a component preload configuration
3 Enabled in self-contained build, which disables generateComponentPreload and generateLibraryPreload
4 Enabled for projects defining a bundle configuration

Processors

Processors work with provided resources. They contain the actual build step logic to apply specific modifications to supplied resources, or to make use of the resources' content to create new resources out of that.

Processors can be implemented generically. The string replacer is an example for that. Since string replacement is a common build step, it can be useful in different contexts, e.g. code, version, date, and copyright replacement. A concrete replacement operation could be achieved by passing a custom configuration to the processor. This way, multiple tasks can make use of the same processor to achieve their build step.

Available processors are listed in the API reference.

Source Map support

Source Maps will be supported by the upcoming v3.0.0 version which is currently in development. Files will be generated automatically for all bundles.

See Migrate to v3 and SAP/ui5-builder#695 for further details.
