Validation

This feature allows you to validate JSON data against a schema. The code sample demonstrates how to define a schema and validate data against it, printing out whether the data is valid or not.

{"const validate = require('json-schema').validate; const schema = {type: 'object', properties: {name: {type: 'string'}, age: {type: 'number', minimum: 0}}, required: ['name', 'age']}; const data = {name: 'John Doe', age: 28}; const result = validate(data, schema); if (result.valid) {console.log('Valid!');} else {console.log('Invalid:', result.errors);} }

Schema Compilation

This feature compiles a JSON schema for faster validation of multiple data sets. The code sample shows how to compile a schema which can then be used to validate data more efficiently.

{"const jsonSchema = require('json-schema'); const schema = {type: 'object', properties: {name: {type: 'string'}, age: {type: 'number', minimum: 0}}, required: ['name', 'age']}; const compiledSchema = jsonSchema.compile(schema); }
