​
Overview

JoyDoc provides validation for required fields, ensuring users complete necessary information before submitting forms. The validation system respects conditional logic and field visibility.

​
How It Works

​
Basic Usage

import { validator } from '@joyfill/components';

// Validate a document
const validation = validator.validate(doc);

​
Validation Logic

  1. Hidden fields are always valid (respects conditional logic)
  2. Non-required fields are always valid
  3. Required fields with empty values are invalid
  4. Required fields with values are valid

​
Empty Value Detection

  • Text/Number/Dropdown: Empty if "", null, or undefined
  • Arrays (image, file, multiSelect): Empty if not array, empty array, or all items are empty strings
  • Table : Empty if field.value is an empty array

​
Configuring Required Fields

Set required: true on any field: 
{
  "_id": "name-field",
  "type": "text",
  "title": "Full Name",
  "value": "",
  "required": true,  // Makes field required
  "file": "file1"
}

​
Validation Results

{
  status: 'valid' | 'invalid' | null,
  fieldValidations: [
    {
      field: { /* field object */ },
      status: 'valid' | 'invalid'
    }
  ]
}
Status meanings:
  • 'valid': All required fields filled
  • 'invalid': One or more required fields empty
  • null: Invalid document structure

​
Implementation Example

import React, { useEffect, useState } from "react";
import { JoyDoc, validator } from "@joyfill/components";

function JoyDocPage() {
  const [doc, setDoc] = useState(null);
  const [validationResult, setValidationResult] = useState(null);

  useEffect(() => {
    const getDocument = async () => {
      try {
        const response = await fetch("YOUR_API_ENDPOINT", {
          method: "GET",
          headers: {
            Authorization: "Bearer YOUR_TOKEN",
            "Content-Type": "text/JSON",
          },
        });

        const data = await response.json();
        setDoc(data);

        // Validate the document
        if (data) {
          const validation = validator.validate(data);
          setValidationResult(validation);
        }
      } catch (e) {
        console.log(e);
      }
    };

    getDocument();
  }, []);

  return (
    <div>
      {/* Validation Status Display */}
      {validationResult && (
        <div
          style={{

Key Points

  • Hidden fields are always valid (respects conditional logic)
  • Validate on document changes using the onChange callback
  • Use visual feedback to show validation status to users
  • Debug with raw validation data when troubleshooting
