Overview

Overview

The function backend encapsulates multiple services into a service by compiling function scripts. Before developing a function backend, familiarize yourself with Custom Backend Development Requirements.

Function backends can be compiled using JavaScript only. The JavaScript engine runs on the Java Virtual Machine (JVM) and can call the Java class provided by ROMA Connect.

Script development must be based on the built-in recommended encryption algorithms.

Common Configuration Reference

You can add global common configurations, such as variables, passwords, and certificates, to the custom backend and reference them in function scripts. For details, see Adding Public Configurations for a Custom Backend.

If the configuration name is example, the reference format is as follows:
  • Template variable: #{example}
  • Password: CipherUtils.getPlainCipherText("example")
  • Certificate: CipherUtils.getPlainCertificate("example")
