In this blog I’ll share with you a helpful strategy I came up with along my Fiori development jouney – reutilizing standard i18n texts.

Introduction

Over the course of a Fiori app development, I was bored of writing some of the most commonly-used labels in the i18n files (like Dialog labels – e.g. “Close”, “Confirm”), over and over, app after app.

I thought to myself “How can I overcome this?”.
Then I decided to experiment to include an i18n file from the UI5 libraries in the app manifest and try it out.

Guess what – it worked 😊

How-to

Basically, all you need to is the following:

• In the app manifest (manifest.json), manually configure a new i18n model (similar to the default ones), mapped to the URL of a i18n file from some UI5 library:

      "models": {
        "i18n": {
          (...)
        },
        "": {
          (...)
        },
        "i18n_sap_m": {
          "type": "sap.ui.model.resource.ResourceModel",
          "settings": {
             "bundleUrl": "/resources/sap/m/messagebundle.properties"
          }
        }
      },

   

  • As a result, it will load the configured (standard) i18n file (allowing you to freely use its texts):
  • Example of bundle URLs:
    • sap.m (/resources/sap/m/messagebundle.properties or https://ui5.sap.com/resources/sap/m/messagebundle.properties)
    • sap.f (/resources/sap/f/messagebundle.properties or https://ui5.sap.com/resources/sap/f/messagebundle.properties)
    • sap.ui.core (/resources/sap/ui/core/messagebundle.properties or https://ui5.sap.com/resources/sap/ui/core/messagebundle.properties)

• Utilize the standard i18n model as you would use your default i18n model – for example:

Note: this does work in any type of UI5 development (UI5 freestyle app, SAP Fiori Elements app, SAP Fiori Launchpad plugin, etc).

Advantages

• Cleaner/Smaller custom i18n files
• Less translation effort (since you’ll be reutilizing standard texts, all their translations will be also reutilized with no effort)

Disadvantages

None 😊

Conclusion

To sum up, by referencing SAP i18n resource bundles, we end up reutilizing existing i18n texts in the UI5 framework, reducing and leading to cleaner Fiori solutions.
