Handling apollo graphql errors globally and render custom ErrorHandler component on error - react-redux

Question

Need to handle Apollo graphql errors globally in client side and render custom ErrorHandler component on error . So I used Apollo's afterware and apollo-link-error
import ApolloClient from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { onError } from 'apollo-link-error'
const httpLink = new HttpLink({ uri: '/graphql' });
const logoutLink = onError(({ networkError }) => {
if (networkError.statusCode === 401) {
//need to dispatch a redux action so that ErrorHandler component renders
}
})
const client = new ApolloClient({
link: logoutLink.concat(httpLink),
});
My solution for this (which I guess, is not the correct approach)
import ApolloClient from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { onError } from 'apollo-link-error';
import { render } from 'react-dom';
import ErrorHandler from '../utils/ErrorHandler';
const httpLink = new HttpLink({ uri: '/graphql' });
const logoutLink = onError(({ networkError }) => {
if (networkError.statusCode === 401) {
const targetDiv = document.getElementById('serviceErrorHandler');
render(
<ErrorHandler message={networkError.message}/>,
targetDiv
);
}
})
const client = new ApolloClient({
link: logoutLink.concat(httpLink),
});
Please suggest an approach for my scenario. Thanks in advance

Had this same problem, one solution we went with was making a function that returns onError and take a parameter (the store):
const errorHandler = store => onError((errors) => {
if (errors.networkError) {
store.dispatch(createApolloErrorAction({
message: GENERIC_ERROR_FETCHING_STRING,
}));
}
});
And use it in a wrapper functions to pass in the store:
let apolloClient = null;
export const createApolloClient = (reduxStore) => {
const cache = new InMemoryCache();
const link = errorHandler(reduxStore).concat(otherLink);
apolloClient = new ApolloClient({ link });
return apolloClient;
};
export const getApolloClient = () => apolloClient;
