Advanced tools
Package description
The har-validator npm package is a library designed to validate HTTP Archive (HAR) files. HAR files are JSON-formatted archives that track all the logging of a web browser's interaction with a site. This package ensures that HAR files adhere to the specification and structure expected, making it useful for developers working with web performance and debugging, API testing, and network monitoring.
HAR file validation
This feature allows developers to validate HAR files against the HAR format specification. The code sample demonstrates how to use the har-validator package to validate a HAR file. If the file is valid, it logs a success message; otherwise, it catches and logs the validation error.
const HARValidator = require('har-validator');
async function validateHAR(harData) {
try {
const valid = await HARValidator.har(harData);
console.log('HAR is valid:', valid);
} catch (err) {
console.error('HAR validation error:', err.message);
}
}Ajv is a fast JSON schema validator. While not specifically designed for HAR files, it can be used to validate any JSON structure against a schema, making it a versatile alternative for general JSON validation tasks. Compared to har-validator, Ajv requires you to define or have access to the JSON schema, offering more flexibility at the cost of requiring more setup for HAR validation.
Tiny Validator (tv4) is another JSON schema validator that supports asynchronous validation and v4 of the JSON Schema standard. Similar to Ajv, it can be used for validating various JSON formats, including HAR files, if the appropriate schema is provided. It's a bit simpler and smaller than Ajv, making it a good choice for projects with less complex validation needs or tighter size constraints.
