library1.0.1jsnpmunverified

Amanda is a JSON Schema validator library for Node.js and the browser, supporting JSON Schema Internet Draft v3. It is designed to be universal and extensible, with plans to support other schema formats. Version 1.0.1 is the latest stable release; the library is lightweight, has no dependencies, works with AMD loaders like RequireJS, and is primarily synchronous with callback-based validation. Unlike modern validators like Ajv, Amanda follows older draft specifications and does not support newer JSON Schema versions.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

amanda

✓ import amanda from 'amanda'

✗ const amanda = require('amanda').default

Default ESM import works as the module exports a function directly.

amanda

✓ const amanda = require('amanda')

CommonJS require works directly as the module uses module.exports.

jsonSchemaValidator

✓ const jsonSchemaValidator = amanda('json')

✗ const jsonSchemaValidator = amanda.json()

Call amanda with the type string 'json' to get a JSON Schema validator instance.

Shows how to create a JSON Schema validator instance and validate an object against a schema using the callback pattern.

import amanda from 'amanda'; const schema = { type: 'object', properties: { name: { required: true, type: 'string' } } }; const data = { name: 'Kenneth' }; const jsonSchemaValidator = amanda('json'); jsonSchemaValidator.validate(data, schema, (error) => { if (error) { console.error('Validation failed:', error); } else { console.log('Valid!'); } });

Debug

Known issues

deprecatedAmanda supports only JSON Schema Internet Draft v3 (draft-zyp-json-schema-03), which is outdated. Use Ajv or other modern validators for newer drafts.

fix

Migrate to Ajv (https://ajv.js.org/) which supports JSON Schema draft-04 and later.

affects: >=0.0.0

gotchaThe validate method uses a callback with a single error argument; it does not return a promise or support async/await natively.

fix

Wrap in a Promise or use a callback pattern.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: amanda is not a function

Using default import in a CommonJS environment without proper transpilation.

fix

Use const amanda = require('amanda') instead of import amanda from 'amanda'.

amanda(...) is not a function

Calling amanda without a type string or with an invalid type.

fix

Ensure you call amanda('json') with the string 'json'.
