library1.6.12jsnpmunverified

Transforms a Draft 7 JSON Schema into a Yup validation schema. Current stable version is 1.6.12, with low release cadence. It supports most Draft 7 keywords including string formats (date-time, email, ipv4, etc.), numeric constraints, array items/tuples, and object properties. Differentiates from schema-to-yup by strictly adhering to the Draft 7 specification. Note: only supports yup v0.29.3 and below; newer yup versions may break.

default

✓ import jsonSchemaToYup from 'json-schema-yup-transformer'

✗ const jsonSchemaToYup = require('json-schema-yup-transformer').default

Package exports a default export. CommonJS require may need .default.

converters

✓ import { converters } from 'json-schema-yup-transformer'

✗ import { convert } from 'json-schema-yup-transformer'

Named export 'converters' is a map of type converters.

errors

✓ import { errors } from 'json-schema-yup-transformer'

✗ import { JsonSchemaError } from 'json-schema-yup-transformer'

Named export 'errors' contains custom error types like InvalidSchemaError.

Converts a JSON Schema to a Yup schema and validates an object. Shows basic object property conversion and requirement handling.

import yup from 'yup'; import jsonSchemaToYup from 'json-schema-yup-transformer'; const jsonSchema = { type: 'object', properties: { name: { type: 'string', minLength: 2 }, age: { type: 'integer', minimum: 0 }, }, required: ['name'], }; const yupSchema = jsonSchemaToYup(jsonSchema); // Now use yupSchema like any Yup schema: yupSchema.validate({ name: 'Alice', age: 30 }).then(() => console.log('valid')); yupSchema.validate({ name: 'A', age: -1 }).catch(err => console.error(err.errors));
