Loading GraphQL operation documents from different sources#

Similar to schema loading - but meant to use for GraphQL documents (query/mutation/subscription/fragment).

Any input provided as a source will be recognized by utils automatically.

It also extracts usages of gql from code files using @graphql-tools/graphql-tag-pluck.

For notes on typescript, refer to loaders

Usage#

const { loadDocuments } = require('@graphql-tools/load')
const { GraphQLFileLoader } = require('@graphql-tools/graphql-file-loader')
const { CodeFileLoader } = require('@graphql-tools/code-file-loader')

// load from string
const document1 = loadDocuments('query { f }')

// load from a single file
const document2 = loadDocuments('./users.query.graphql', {
  loaders: [new GraphQLFileLoader()]
})

// load from multiple files using glob
const document3 = loadDocuments('./src/**/*.graphql', {
  loaders: [new GraphQLFileLoader()]
})

// load from code file
const document4 = loadDocuments('./src/my-component.ts', {
  loaders: [new CodeFileLoader()]
})

loadDocuments returns an array of document sources. Each source object has the following structure:

interface DocumentSource {
  document: DocumentNode // Object representation of GraphQL Content
  rawSDL: string // SDL in text
  location: string // Way to access to that source
}

loadDocuments takes in additional configuration via the options object (the second argument). There are some defaults to be aware of - to learn more, see the full API documentation.
