Error Handling
GraphQLade servers allow passing a resolverErrorHandler function
which will handle errors thrown in resolvers.
This is useful for reporting errors (to the console or another logger) and security (for masking errors that clients should not see).
Note that you cannot cancel errors in resolvers using this function.
Example
import { GraphQLServer } from 'graphqlade';
import { GraphQLContext } from './GraphQLContext';
import { resolvers } from './resolvers';
const gqlServer = await GraphQLServer.bootstrap<GraphQLContext>({
// ... other options ...
resolverErrorHandler(err, source, args, context, info) {
// report error
console.error(err.stack, context.headers['x-request-id']);
if (!isClientSafeError(err)) {
// return safe error for clients
return new Error('Internal server error');
}
},
});
