UI5 middleware to serve a locally built UI5 framework version

:wave: 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 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

• Requires at least @ui5/[email protected] (to support specVersion: "3.0")

:warning: 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-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
• strictSSL: boolean Ignore strict SSL checks. Default value true.
• saveLibsLocal: boolean, default: false When enabled, libraries are saved in the project directory (.ui5-middleware-serveframework) instead of the user home directory. While this isolates the libraries per project, it requires additional disk space and compilation time compared to sharing compiled libraries across projects.
• cachePath: string Custom path to store cached framework files. By default, files are stored in the user home directory (~/.ui5/ui5-middleware-serveframework) or project directory depending on saveLibsLocal setting.

Usage

1. Define the dependency in $yourapp/package.json:

"devDependencies": {
    // ...
    "ui5-middleware-serveframework": "*"
    // ...
}

2. 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.
