What's the Difference Between OpenUI5 and SAPUI5?¶
The open source project OpenUI5 provides most of the fundamental framework features. SAPUI5 enhances this by providing additional libraries under a different license.
OpenUI5 is provided under the Apache 2.0 license. The SAPUI5 packages that are consumed in UI5 Tooling are provided under the terms of the SAP Developer License Agreement.
Note that projects which use the OpenUI5 framework cannot depend on projects that use the SAPUI5 framework. However, SAPUI5 projects can depend on OpenUI5 projects.
Please also see the UI5 SDK documentation "SAPUI5 vs. OpenUI5".
Why package.json? / Why npm?¶
Currently, the tooling can only resolve dependencies defined in a
package.json file. This might change in the future by adding Translators for additional dependency management systems.
To manage your dependencies, you can use almost any
Node.js package manager that relies on
package.json files. Popular ones are npm, Yarn and pnpm.
The UI5 Tooling resolves dependencies almost the same way Node.js does when executing a
What's the Thing With Yarn?¶
In a couple of guides we refer to the Yarn node package manager. This is because it offers functionality that the otherwise preferred npm package manager is lacking in Version 6 and below. In particular, this applies to the workspace setting, which is currently used in the OpenUI5 (mono-)repository. Note that npm recently added this feature to its v7 release.
If you do not plan to work with OpenUI5, you may as well use npm or any other node package manger (see FAQ: Why package.json? / Why npm?). Keep in mind that linking the same module with npm and Yarn may cause issues. Also, Yarn can't work with links created by npm and vice versa.
