问题 Simple joi validation snippet in javascript.It will simply return an error object when validation fails. validate.js const Joi =require("joi"); function validateObject (input) { const schema = { key: Joi.string().required(), }; return Joi.validate(input, schema); }; let {error} = validateObject({key:5}) console.log(error) Now I am learning typescript and like to do the exact functionality in TS.I am aware that Joi is a javascript library but can we make use of it in Typescript.When exploring

What i am looking for is this https://github.com/hapijs/joi/issues/1066 (version v10.5.2) but with the syntax of older version of

Joi validation set default as empty object

由 南楼画角 提交于 2019-12-11 09:07:04
问题 I'm running into an issue (or what I believe to be one) with Joi validation. I'm trying to assign a value to a non-existent key if it's been passed as part of the request body. So for example: parameters: Joi.object().keys({ keyA: Joi.string().allow('').allow(null).default(null), keyB: Joi.object().keys({ b1: Joi.string(), b2: Joi.string(), b3: Joi.object().keys({ b3_1: Joi.string(), b3_2: Joi.string(), b3_3: Joi.string() }) }).default({}), keyC: Joi.object().keys({ c1: Joi.number(), c2: Joi

Validate two properties are equal

由 最后都变了- 提交于 2019-12-11 05:58:43
问题 Is it possible to validate that two object properties of type string are equal using Joi ? I found Joi.ref() but I wonder if there's another way of doing it. Especially as Joi.ref() doesn't seem to support any.error() 回答1: Yes, it is possible to check if two properties on a object are the same. And using Joi.ref() is the preferred way to do it. If you want to use custom error messages the Joi.any.messages() option works the best. The Joi.any.messages() lets you overwrite the different error

hapi route joi validation of password confirmation

由 不问归期 提交于 2019-12-10 03:59:37
问题 How do I check that password and password_confirmation are the same ? var Joi = require('joi'), S = Joi.string().required().min(3).max(15); exports.create = { payload: { username: S, email: Joi.string().email(), password: S, password_confirmation: S } } 回答1: You can use Joi.any().valid() with Joi.ref(): password: Joi.string().min(3).max(15).required(), password_confirmation: Joi.any().valid(Joi.ref('password')).required().options({ language: { any: { allowOnly: 'must match password' } } }) 来源

How to capture callback from failed validation in Joi

由 你。 提交于 2019-12-08 04:54:49
问题 We're building a web service using Hapi. Our routes have some validation. I was wondering if it was possible to capture or override the default callback on failed validation, before or after hapi replies to the client. my (non-working) code: { method: 'GET', config: { tags: tags, validate: { params: { id: Joi.number() .required() .description('id of object you want to get'), }, //Tried this, and it's not working: callback: function(err, value) { if (err) { console.log('need to catch errors

Are there ways to populate a schema in Joi from another schema (like Mongoose does)?

由 时光毁灭记忆、已成空白 提交于 2019-12-08 03:38:17
问题 I'm currently only using Joi to validate and building schemas. However I feel like I'm missing features like reference another schema like Mongoose does. Or is the only way to do this by using both (or mongoose only)? I want to use something similar to this: const mongoose = require('mongoose'); const Schema = mongoose.Schema; const personSchema = Schema({ _id: Schema.Types.ObjectId, name: String, age: Number, stories: [{ type: Schema.Types.ObjectId, ref: 'Story' }] }); const storySchema =
