ui5-middleware-webjars

A UI5 dev-server middleware that loads JAR files from a configured path and serves the static resources bundled inside them, following the WebJars convention of META-INF/resources/.

Searches a configured rootPath for JAR files, loads them, and serves their contents through the UI5 dev server, following the Servlet 3.0 WebJars convention of resources under META-INF/resources/. The classpath of JARs to search can be generated with Maven's dependency:build-classpath goal into a classpathFile. The jarRootPath option overrides which path inside the JAR is treated as the resource root, changing the URL a resource is served at.

UI5 middleware for delivering content from JAR files

👋 This is an open‑source, community‑driven project, developed and actively monitored by members of the UI5 community. You are welcome to use it, report issues, contribute enhancements, and support others in the community.

Middleware for ui5-server, delivering the content of JAR files.

Prerequisites

⚠️ UI5 CLI Compatibility All releases of this UI5 CLI extension using the major version 3 require UI5 CLI V3. Any previous releases below major version 3 (if available) also support older versions of the UI5 CLI. But the usage of the latest UI5 CLI is strongly recommended!

Install

npm install ui5-middleware-webjars --save-dev

Configuration options (in $yourapp/ui5.yaml)

  • classpathFile: string

    the file containing the classpath (list of files, separated with the path delimiter) which can be created via:

    mvn clean dependency:build-classpath -Dmdep.cpFile=target/classpath

  • rootPath: string

    the root path to the static resources on your system

  • jarRootPath: string, default: META-INF/resources/

    the root path in the JAR file containing the static resources

  • debug: boolean, default: false

Usage

  1. Define the dependency in $yourapp/package.json:
"devDependencies": {
    // ...
    "ui5-middleware-webjars": "*"
    // ...
}
  1. configure it in $yourapp/ui5.yaml:
server:
  customMiddleware:
  - name: ui5-middleware-webjars
    afterMiddleware: compression
    configuration:
      rootPath: "jars"
      jarRootPath: "META-INF/"

How it works

The middleware searches for JAR files in the rootPath, loads them and serves the content from JAR files following the web static resources concept of Servlet 3.0 (WebJARs). By default, this allows to consume static resources from the JAR files from within the META-INF/resources/ path. When using JAR files following a derived web static resources concept it is possible to override the JAR root path with the configuration jarRootPath.

jarRootPath: "META-INF/resources/"

META-INF/resources/my/resource/path/Resource.js => http://localhost:8080/my/resource/path/Resource.js

---
jarRootPath: "META-INF/"

META-INF/resources/my/resource/path/Resource.js => http://localhost:8080/resources/my/resource/path/Resource.js
