Usage#
This plugin adds an extra registerDataLoader in your ezApp, which will automatically add the specified dataloader in your GraphQL EZ Application Context.
This EZ Plugin uses @envelop/dataloader plugin seamlessly while you code
import { ezDataLoader } from '@graphql-ez/plugin-dataloader';
const ezApp = CreateApp({
ez: {
plugins: [
ezDataLoader(),
// ...
],
},
// ...
});
// ...
import type { InferDataLoader } from '@graphql-ez/plugin-dataloader';
const multiplierDataLoader = ezApp.registerDataLoader(
'Multiplier',
DataLoader =>
new DataLoader<number, number>(async numbers => {
return numbers.map(v => v * 2);
})
);
// This snippet add automatically the type of your DataLoader in your EZContext
declare module 'graphql-ez' {
interface EZContext extends InferDataLoader<typeof multiplierDataLoader> {}
}
// And if you are using https://www.graphql-ez.com/plugins/graphql-modules
// You could use it like this:
ezApp.registerModule(
gql`
extend type Query {
multiply(n: Float!): Float!
}
`,
{
resolvers: {
Query: {
multiply(_root, { n }, { Multiplier }) {
return Multiplier.load(n);
},
},
},
}
);
