IfThen with constant

💬 Questions and Help

I don't find if it is possible to write this json schema:

{
  "type": "object",
  "properties": {
    "type": {
      "type": "string",
      "enum": ["AS", "RP"]
    }
  },
  "if": {
    "properties": { "type": { "const": "RP" } }
  },
  "then": {
    "properties": { "issueType": { "type": "string" } },
    "required": [ "issueType" ]
  }
}

I'm trying the code:

const S = require('fluent-schema')

const fs = S.object()
  .prop('type', S.string().enum(['AS', 'CS', 'RP']))
  .ifThen(
    // S.object().prop('type', S.string().default('RP')),
    S.object().prop('type', 'RP'),
    S.object().prop('issueType', S.string().required())
  )

console.log(JSON.stringify(fs.valueOf(), null, 2))

But I get:

  "if": {
    "properties": {
      "type": {
        "0": "R",
        "1": "P"
      }
    }
  },

or

  "if": {
    "properties": {
      "type": {
        "type": "string",
        "default": "RP"
      }
    }
  },

Should I use S.raw?

Actually I found how to do it:

const schema = S.object()
          .prop('type', S.string().enum(['AS', 'CS', 'RP']))
          .ifThen(
            S.object().prop('type', S.const('RP')),
            S.object().prop('issueType', S.string().required())
          )
          .valueOf()

output

 {
      "$schema": "http://json-schema.org/draft-07/schema#",
      "type": "object",
      "properties": {
        "type": {
          "type": "string",
          "enum": [
            "AS",
            "CS",
            "RP"
          ]
        }
      },
      "if": {
        "properties": {
          "type": {
            "const": "RP"
          }
        }
      },
      "then": {
        "properties": {
          "issueType": {
            "type": "string"
          }
        },
        "required": [
          "issueType"
        ]
      }
    }
