graphql-compose-dataloader – DEPRECATED

Add DataLoader to graphql-composer resolvers.

Deprecation reason

DataLoader cannot be expressed like a simple plugin. Mostly this plugin was used with graphql-compose-mongoose models. From graphql-compose-mongoose@9.0.0 (read more) it starts provide new built-in resolvers dataLoader & dataLoaderMany resolvers which implement DataLoader logic in different manner.

Installation

Modules graphql, graphql-compose are in peerDependencies, so should be installed explicitly in your app. They have global objects and should not have ability to be installed as submodule.

const LanguagesSchema = new mongoose.Schema({
  language: String,
  skill: {
    type: String,
    enum: [ 'basic', 'fluent', 'native' ],
  },
});

const Languages = mongoose.model('Languages', LanguagesSchema)
const LanguagesTC = composeWithDataLoader(composeWithMongoose(Languages),{cacheExpiration: 700})

Props
