How to add multiple conditions in JSON schema? - node.js

Question

I have the below JSON schema
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"items": {
"type": "object",
"properties": {
"op": {
"type": "string",
"minLength": 1,
"enum": [
"add",
"remove",
"replace"
]
},
"path": {
"type": "string",
"minLength": 1,
"enum": [
"/name",
"/description",
"/prefix"
]
},
"value": {
"type": "string",
"minLength": 1
}
},
"additionalProperties": false,
"required": [
"op",
"path",
"value"
],
"minItems": 1,
"allOf": [
{
"if" : {
"properties": {
"path" : {
"const": "/name"
}
}
},
"then": {
"properties": {
"op": {
"const": "replace"
}
}
}
},
{
"if" : {
"properties": {
"path" : {
"const": "/description"
}
}
},
"then": {
"properties": {
"op": {
"const": "replace"
}
}
}
}
]
}
}
As above we can see , if name and description are there ,then op will be replace and for path prefix I have all the operations i.e add , remove and replace , but i want a special condition to be applied for remove operation
Like if path is xFix and op is remove then required parameters should not contain value attrribute , so only op and path.

I think you'll want to turn the logic of that around. Do not include "value" in the "required" list. Instead, add a condition that says, basically, "if op is not 'remove', then value is required".
{
"if" : {
"not": {
"properties": {
"op" : {
"const": "remove"
}
}
}
},
"then": {
"required": ["value"]
}
}
