@rjsf/utils

What is @rjsf/utils?

@rjsf/utils is a utility library for React JSON Schema Form (RJSF). It provides a set of helper functions and utilities to work with JSON schemas, form data, and UI schemas. This package is designed to simplify the process of creating and managing forms using JSON schema definitions.

What are @rjsf/utils's main functionalities?

Schema Validation

This feature allows you to validate form data against a JSON schema. The `validateFormData` function takes form data and a schema as inputs and returns validation errors if any.

const { validateFormData } = require('@rjsf/utils');
const schema = { type: 'object', properties: { name: { type: 'string' } } };
const formData = { name: 'John Doe' };
const result = validateFormData(formData, schema);
console.log(result.errors);

Schema Merging

This feature allows you to merge multiple JSON schemas into one. The `mergeSchemas` function takes two or more schemas and combines them into a single schema.

const { mergeSchemas } = require('@rjsf/utils');
const schema1 = { type: 'object', properties: { name: { type: 'string' } } };
const schema2 = { type: 'object', properties: { age: { type: 'number' } } };
const mergedSchema = mergeSchemas(schema1, schema2);
console.log(mergedSchema);

Form Data Manipulation

This feature allows you to manipulate form data based on a schema. The `getDefaultFormState` function takes a schema and form data as inputs and returns the default form state.

const { getDefaultFormState } = require('@rjsf/utils');
const schema = { type: 'object', properties: { name: { type: 'string' }, age: { type: 'number' } } };
const formData = { name: 'John Doe' };
const defaultFormData = getDefaultFormState(schema, formData);
console.log(defaultFormData);

Other packages similar to @rjsf/utils

ajv

AJV (Another JSON Schema Validator) is a popular JSON schema validator. It provides high-performance validation of JSON schemas and is widely used in the JavaScript ecosystem. Compared to @rjsf/utils, AJV focuses more on schema validation and less on form-specific utilities.

json-schema-faker

JSON Schema Faker is a library that generates fake data based on a JSON schema. It is useful for testing and prototyping. While @rjsf/utils focuses on form utilities, JSON Schema Faker is more about generating mock data from schemas.

react-jsonschema-form

React JSONSchema Form is a library for building forms from JSON schema definitions. It includes a set of utilities similar to @rjsf/utils but is more focused on the form rendering aspect. @rjsf/utils can be seen as a subset of the utilities provided by React JSONSchema Form.
