Builder

ChaosConfigBuilder creates readable configs for larger scenarios.

import { ChaosConfigBuilder } from '@chaos-maker/core';

const config = new ChaosConfigBuilder()
  .failRequests('/api/checkout', 503, 0.5)
  .addLatency('/api/', 1500, 0.3)
  .corruptResponses('/api/cart', 'malformed-json', 0.2)
  .failGraphQLOperation('GetUser', 503, 1, '/graphql')
  .delaySSE('/events', 500, 1, 'token')
  .assaultUi('button[type="submit"]', 'disable', 0.1)
  .build();

Builder output is a normal ChaosConfig. You can still add seed at the root:

const config = {
  ...new ChaosConfigBuilder().failRequests('/api/payments', 503, 1).build(),
  seed: 42,
};

Prefer plain objects for small tests and the builder when a scenario spans several chaos primitives.

GraphQL shortcuts default urlPattern to '*' when you omit the fourth argument. SSE shortcuts accept an optional eventType after the probability.
