CURP Validation Module

The CURP Validation module verifies a Mexican CURP (Clave Única de Registro de Población) — either by accepting the user's CURP and validating it server-side, or by generating one from the user's identity data when missing.

Follows the form-based pattern with three input variants (enter, confirm, generate). See the patterns page for the shared lifecycle.

Tag

<incode-curp-validation> is a standard Web Component. Importing the UI subpath registers the custom element; importing the CSS applies the module's styles.

import '@incodetech/web/curp-validation';
import '@incodetech/web/curp-validation/styles.css';

Properties

Property	Type	Required	Description
`config`	`CurpValidationConfig`	❌	Configuration options
`onFinish`	`() => void`	❌	Called when validation completes
`onError`	`(error: string) => void`	❌	Called when an error occurs

Configuration

CurpValidationConfig extends FlowModuleConfig['CURP_VALIDATION'] with two manager-level options:

type CurpValidationConfig = FlowModuleConfig['CURP_VALIDATION'] & {
  maxRetries?: number; // Maximum validation retries before auto-advancing (default: 1)
  prefillFromOcr?: boolean; // Attempt OCR pre-fill on load (default: true)
};

Option	Type	Required	Description
`maxRetries`	`number`	❌	Auto-advance after this many failed validation attempts. Default `1`.
`prefillFromOcr`	`boolean`	❌	Pre-fill the CURP field from prior ID OCR data when available. Default `true`.

Plus the dashboard-driven fields from FlowModuleConfig['CURP_VALIDATION'].

State machine

CurpValidationState is a discriminated union over status:

Status	Description
`idle`	Initial state.
`loading`	Loading prior OCR data (when `prefillFromOcr` is `true`).
`enterCurp`	User enters their CURP.
`verifying`	Backend verifying the entered CURP.
`confirmCurp`	Backend returned an OCR'd CURP candidate; user confirms or rejects.
`generateCurp`	No CURP available; user fills the generate form (name, DOB, gender, birth state).
`generating`	Backend generating a CURP from the form.
`generateError`	Generate failed; user can retry.
`success`	CURP validated.
`failure`	Validation failed (deceased status, mismatch, etc.).
`finished`	Terminal.
`closed`	User dismissed.
