GraphQL Query Batcher

Note: "Query" is used broadly to mean both query and mutation

Overview

• build GraphQL queries
• batch execute those queries

Need quick batching? factory function is the answer Need to split the query build and query batching process? Checkout builder and batcher

Sample project: graphql-query-factory-test

Status

• factory included as of 1.0.20 (shim around builder and batcher)
• batcher included as of 1.0.20 (executes array of queries)
• builder updated (this builds query strings from query/mutation and variables)

Action Items

You can see TODOs and release plans in todo.md

Getting Started

Installation

npm install graphql-query-factory -S

Configuration (Environment Variables)

When using factory or batcher you must include two environment variables:

• GQL_SIMPLE_ENDPOINT
• GQL_AUTH_TOKEN

Examples

All of these examples can be seen at graphql-query-factory-test

All mock variables (e.g. "mock.template", "mock.variables") can be viewed here: .../tests/_mock.js

builder

const { builder } = require('graphql-query-factory');

let queries = builder(mock.template, mock.variables);
log(`builder(mock.template, mock.variables): ${queries}`);

NOTE: async version has been replaced here with sync version. Will be adding async version of builder in future along with a stream. See todo.md for details.

factory

const { factory } = require('graphql-query-factory');

factory(mock.template, mock.variables)
  .then(data =>
    log(
      `factory(mock.template, mock.variables): ${JSON.stringify(data, null, 4)}`
    )
  )
  .catch(err => log(`factory(mock.template, mock.variables): ${err}`));

batcher

const { batcher } = require('graphql-query-factory');

batcher
  .batch(mock.batchQuery)
  .then(data =>
    log(`batcher.batch(mock.batchQuery): ${JSON.stringify(data, null, 4)}`)
  )
  .catch(err => log(`batcher.batch(mock.batchQuery): ${err}`));

Output

The following output is generated by the example project, graphql-query-factory-test
