JSON Schema Validation: Build robust API contracts

Challenges

In microservice architecture, back-to-back interaction depends on JSON Data. If the back end changes the field name or sends the wrong data type, it is often only found when the error is reported at the running time, which results in high debugging costs and high vulnerability to production accidents.

Our solution.

By introducing JSON Schema, you can define a " contract" for data. It not only describes the data structure but also provides the range, required entries and format of values. This certifier helps you to intercept all data that are not in conformity with the contract at the development stage and to ensure the stability of the system.

What's JSON Schema?

JSON Schema is a statement language based on JSON format for comments and validation of JSON documents. It's like XML. Schema (XSD) or table structure definition for a database, but lighter and easier to read.

  • Structure definition : Define which fields are necessary and which are optional.
  • Type binding : Ensure age The number is not a string. email Matches the mail format.
  • Logical Validation : Support complex conditionality judgements, such as if-then-else and allOf / anyOf Like a logical combination.

Why this certifier?

Unlike simple regular matches, this tool is industrial. Ajv (Another JSON Validator) Engine:

  • Full-Specific Support : Compatibility of JSON Schema Draft-07, Draft 2019-09 and the latest 2020-12 norms.
  • High Performance Validation : Ajv compiles Schema into a highly optimized JavaScript function, even processing big data can be quick to verify.
  • Rich Format support : Inline pairing email , ipv4 , date-time , uri , uuid .
  • - Exactly. : Provides specific error paths (Data Path) and easy to understand error messages, directly to the problem JSON node.

Core application scenario

  1. API Interface Document : Generates a Swagger or OpenAPI document using JSON Schema as a standard for interface definition.
  2. Form authentication : At the front end generate forms based on Schema's dynamic and verify real-time data.
  3. Mark Data Generation : Automatically generate standardised random test data according to the Schema rule.
  4. Configuration audit : Verify complex software profiles (e. g. package.json or tsconfig.json Whether it's right or not.

Privacy statements

Your privacy is vital to us. All validation logic is executed locally on your browser. We're not gonna put your JSON data or Schema sends to any server for processing to ensure that your business data and contract definition are absolutely secure.
