I have a object, cache declared as follows:
const cache = new InMemoryCache({);
I want to create a separate file the I can configure all the parameters that get passed into InMemoryCache({...}). When I create a new file called cache.js that looks like this,
export const cache = new InMemoryCache();
and then from my mail file, import it as `import {cache} from './cache.js'
I get different behavior then from my original code. I'm thinking I'm not getting what new is doing here. Suggestions?
new
is used to create a new instance of an object (in this case, InMemoryCache
).
If you want to export this single instance that you defined using
const cache = new InMemoryCache({});
you need to make the export as
export { cache };
which will export the previously created instance.
If you also want to be able to create a new instance from elsewhere, you can export the constructor with
export { InMemoryCache };
(you can merge both exports together)
And then you can later import cache
(the instance already defined), and InMemoryCache
(the constructor) using
import { cache, InMemoryCache } from '<FILENAME>';
