Arrays in OpenMRS MF Configurations

array-config.js

// Example 1: Array of primitives

// input
foo: [2, 42, 99]

// schema
{
  foo: {
    default: [1, 1, 2, 3],
    arrayElements: {
      validators: [isInteger]
    },
    validators: [
      lengthBetween(1, 4)
    ]
  }
} 


// Example 2: Array of objects

// input
foo: [
  { qux: "abc", quy: "xyz" },
  { qux: "bcd" },
  { quy: "def" }
]

// schema
{
  foo: {
    default: [
      { qux: "qux1", quy: "quy1" },
      { quy: "quy2" }
    ],
    arrayElements: {
      qux: {
        default: "N/A",
        validators: [isString]
      },
      quy: {
        default: "",
        validators: [isString]
      }
    },
    validators: [lengthBetween(1, 4)]
  }
} 

// result
foo: [
  { qux: "abc", quy: "xyz" },
  { qux: "bcd", quy: "" },
  { qux: "N/A", quy: "def" }
]

// Default resulting config object (with no provided config input):
foo: [
  { qux: "qux1", quy: "quy1" },
  { qux: "N/A", quy: "quy2" }
]
