Error codes hooks

Solver error-code registry lookups. Turn a numeric code into a human-readable message for UI display.

Read only.

Import

import { useSolverErrorCodes, useSolverErrorMessage } from "@symmio/trading-react";

useSolverErrorCodes

Fetch the full registry. Cache once — the registry is stable per solver deployment.

const codes = useSolverErrorCodes();

useSolverErrorMessage

Look up a message by code. Composed on top of useSolverErrorCodes.

const message = useSolverErrorMessage(42);

The code is positional (useSolverErrorMessage(code?: number | null)) and the hook returns the resolved message as a string | undefined — not a query result.

Common usage — render a solver rejection reason:

const mutation = useInstantOpenAuto();
const message = useSolverErrorMessage(mutation.error?.responseData?.code);
 
{
  mutation.error ? <ErrorNote>{message ?? mutation.error.message}</ErrorNote> : null;
}
