How To Type An Exported Relaycontainer

So, you've been working on your React project and have come across the need to export and reuse a Relaycontainer component. Well, fear not, as we are here to guide you through the process of typing an exported Relaycontainer like a pro.

First things first, ensure that you have the necessary dependencies installed for Relay. You will need to have relay-runtime and relay-hooks included in your project. If you haven't already, you can install these packages by running the following command in your terminal:

npm install relay-runtime relay-hooks

Once you have the dependencies set up, let's move on to typing the exported Relaycontainer. The key to typing a Relaycontainer lies in defining the correct types for the Relay container props. This will help you make the Relay container reusable and maintainable in your codebase.

Here's an example of how you can type an exported Relaycontainer in your React component file:

import { Container } from 'relay-hooks';
import { ComponentName_query$key } from './__generated__/ComponentName_query.graphql';

type Props = {
  query: ComponentName_query$key;
};

const ComponentName: React.FC = ({ query }) => {
  return (
    
  );
};

export default ComponentName;

In this example, we define a Props type that includes the query prop with the corresponding graphql generated type. We then use this Props type to annotate the functional component, ensuring that the query prop is correctly typed when the Relaycontainer is exported.

Additionally, when exporting a Relaycontainer, make sure that you are passing the correct props to the Container component. The Container component takes in two props: component and query. The component prop should point to the React component you are exporting, and the query prop should be of the correct graphql generated type for the query used in the Relay container.

By following these steps and ensuring that your Relaycontainer is correctly typed and exported, you can enhance the readability and maintainability of your codebase. Typed Relay containers not only make your code more robust but also help with catching errors early on during development.

So, the next time you need to export a Relaycontainer in your React project, remember to type it like a champ using the guidelines provided in this article. Happy coding!
