Code below worked for me. I used alternatives because .or is really testing for the existence of keys and what you really wanted was an alternative where you would allow one key or the other to be empty. var console = require(“consoleit”); var Joi = require(‘joi’); var schema = Joi.alternatives().try( Joi.object().keys({ a: Joi.string().allow(”), b: Joi.string() … Read more
I achieved the same in a little different manner. Posting the same here since this might be useful for someone in future. const schema = Joi.object({ type: Joi.number().required().valid(1, 2, 3), firstname: Joi.alternatives().conditional(‘type’, { is: 1, then: Joi.string().required() }), lastname: Joi.alternatives().conditional(‘type’, { is: 1, then: Joi.string().required() }), salary: Joi.alternatives().conditional(‘type’, { is: 2, then: Joi.number().required() }), pension: … Read more
Try this. It’ll basically accept any key within an object campaign and the value must validate against Joi.date().iso() campaign: Joi.object().pattern(/^/, Joi.date().iso()) This however will match any key. You can restrict this by padding out the regex a little. e.g. only word characters between 2 and 25 chars campaign: Joi.object().pattern(/\w{2,25}/, Joi.date().iso()) UPDATE Regarding the example in … Read more
You are looking for the valid and invalid functions. v16: https://hapi.dev/module/joi/api/?v=16.1.8#anyvalidvalues—aliases-equal v17: https://hapi.dev/module/joi/api/?v=17.1.1#anyvalidvalues—aliases-equal As of Joi v16 valid and invalid no longer accepts arrays, they take a variable number of arguments. Your code becomes var schema = Joi.object().keys({ firstname: Joi.string().valid(…[‘a’,’b’]), lastname: Joi.string().invalid(…[‘c’,’d’]), }); Can also just pass in as .valid(‘a’, ‘b’) if not getting the … Read more
const Joi = require(‘@hapi/joi’); Joi.object({ password: Joi .string() .custom((value, helper) => { if (value.length < 8) { return helper.message(“Password must be at least 8 characters long”); } return true; }) }).validate({ password: ‘1234’ });
In the past, it was true that joi lacked browser support, at least out of the box. It uses a few Node.js APIs, which aren’t available in the browser, to implement some of its features. It was still possible to use Browserify on it, or use the unofficial joi-browser npm package, but the process was … Read more
You can fix it by changing: joi.validate(request, validationSchema) to: validationSchema.validate(request) joi.validate() Is no longer supported in v16. It is clearly documented in the API docs and release notes.
You can concatenate two when rules: var schema = { a: Joi.string(), b: Joi.string(), c: Joi.string().when(‘a’, { is: ‘avalue’, then: Joi.string().required() }).concat(Joi.string().when(‘b’, { is: ‘bvalue’, then: Joi.string().required() })) };
The important difference between AJV and Joi is that AJV is a JSON Schema validator and Joi is a JavaScript validator. JSON Schema is cross-platform while Joi only works in JavaScript. So, this isn’t a choice between AJV and Joi as much as it’s a choice between JSON Schema and Joi. Each approach has its … Read more
You could also specify this with a comma delimited list. dataId: Joi.string().allow(null, ”) See Joi documentation on allow(value)
