What are you trying to achieve or the steps to reproduce ?
I have tried to add new rule for object but after it many validations become broken.
Example of code to reproduce is below.
const Joi = require('joi');
const schema = Joi.object({
position: Joi.object({
x: Joi.number(),
y: Joi.number()
}).required()
});
const data = {
position: JSON.stringify({
x: 100,
y: 200
})
};
console.log(Joi.validate(data, schema));
/*
There I got result as expected. There will be error if data.position.x = 'hello'
*/
/*
{ error: null,
value: { position: { x: 100, y: 200 } },
then: [Function: then],
catch: [Function: catch] }
*/const origJoi = require('joi');
const Joi = origJoi.extend((joi) => {
return {
name: 'object',
base: joi.object(),
rules: [{
name: 'newRule',
validate (params, value, state, options) {
return value;
}
}]
};
});
const schema = Joi.object({
position: Joi.object({
x: Joi.number(),
y: Joi.number()
}).required()
});
const data = {
position: JSON.stringify({
x: 'hello',
y: 200
})
};
console.log(Joi.validate(data, schema));
/*
There is unexpected result. There is no error on data.position.x and data.position is not parsed
*/
/*
{ error: null,
value: { position: '{"x":"hello","y":200}' },
then: [Function: then],
catch: [Function: catch] }
*/
