Validating unique key pairs in a nested object with Joi and nodeJS
up vote

I have the following JSON structure:
{
key1: "value1",
key2: "value2",
transactions: [
{
receiverId: '12341',
senderId: '51634',
someOtherKey: 'value'
},
{
receiverId: '97561',
senderId: '46510',
someOtherKey: 'value'
}
]
}I'm trying to write some Joi code to validate that each object in the transactions array is unique i.e. a combination of receiverId and senderId is only ever present once. There can be a variable number of elements in the transactions array but there will always be at least 1.
Any thoughts?

You can use array.unique
const array_uniq_schema = Joi.array().unique((a, b) => a.receiverId === b.receiverId && a.senderId === b.senderId);
So for the whole object the schema would be (assuming all properties are required):
const schema = Joi.object({
key1: Joi.string().required(),
key2: Joi.string().required(),
transactions: array_uniq_schema.required(),
});
