What is har-schema?
The har-schema npm package provides JSON schemas for HTTP Archive (HAR) format. HAR is a common format used for logging web browser interactions with websites. The schemas provided by har-schema can be used to validate HAR files to ensure they conform to the expected structure.
What are har-schema's main functionalities?
Validate HAR Log
This feature allows you to validate a HAR log against the HAR schema. The code sample uses the Ajv library to compile the HAR log schema and validate a HAR log data object.
const Ajv = require('ajv');
const harSchema = require('har-schema');
const ajv = new Ajv();
const validate = ajv.compile(harSchema.log);
const data = { /* HAR log data */ };
const valid = validate(data);
if (!valid) console.log(validate.errors);
Validate HAR Entries
This feature allows you to validate individual HAR entries against the HAR schema. The code sample uses the Ajv library to compile the HAR entry schema and validate a HAR entry data object.
const Ajv = require('ajv');
const harSchema = require('har-schema');
const ajv = new Ajv();
const validate = ajv.compile(harSchema.entry);
const data = { /* HAR entry data */ };
const valid = validate(data);
if (!valid) console.log(validate.errors);
