UI5 middleware to serve a locally built UI5 framework version

👋 This is a community project and there is no official support for this package! Feel free to use it, open issues, contribute, and help answering questions.

Middleware for ui5-server, delivering the UI5 framework from a locally built version. The first time a UI5 version is being used (derived from the framework configuration of the project), it will be built and locally stored in the ~/.ui5/ui5-middleware-serveframework folder per version. For any follow-up usage of the version, it will be served from the local folder. Benefits are the usage of the preload files and pure static file access.

Prerequisites

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

Install

npm install ui5-middleware-serveframework --save-dev

Configuration options (in $yourapp/ui5.yaml)

  • debug: boolean, default: false
  • ui5VersionEnvVariable: string Name of environment variable that contains ui5 version (in case you want to override framework version from ui5.yaml)
  • envFilePath: string, default: ./.env Path to file with environment variables

Usage

  1. Define the dependency in $yourapp/package.json:
"devDependencies": {
    // ...
    "ui5-middleware-serveframework": "*"
    // ...
}
  1. configure it in $yourapp/ui5.yaml:
server:
  customMiddleware:
  - name: ui5-middleware-serveframework
    afterMiddleware: compression
    configuration:
      ui5VersionEnvVariable: UI5_VERSION
      envFilePath: "./.dev.env"

How it works

The middleware looks-up the UI5 framework version in the ui5.yaml and then first builds the framework with all libraries locally and serves the content of those libraries from there.
