apollo client mutation update cache code example

Example: apollo client mutation without component

// react-apollo includes two HOCs called graphql() and withApollo() that can be used to accomplish this.
// This example takes the withApollo() HOC approach

import React, { Component } from "react";
import { DO_MUTATION } from "./mutations";
import { withApollo } from "react-apollo";

import SomeLibrary from "SomeLibrary";

export class MyComponent extends Component {
    render() {
        return (
            <Button
                onPress={() => {
                    SomeLibrary.addListener(this.listenerHandler);
                }}
            />
        );
    }

    listenerHandler = () => {
        this.props.client.mutate({
            mutation: DO_MUTATION,
            variables: {
                some_var: "some_val",
            },
        });
    };
}
export default withApollo(MyComponent);
