What is json-schema?

The json-schema npm package is used to validate JSON data against a JSON schema. It ensures that the JSON data is structured in the way that is expected by the schema. This package can be used to validate configuration files, user input, or any other data represented in JSON format.

What are json-schema's main functionalities?

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); }
