graphql-schema-loader
This is a boilerplate schema structure and loader utils to provide file-based organization for GraphQL schemas. Included in this module is a basic Github public API example.
Usage is simple
Install as npm module
$ npm install graphql-schema-loader --save
Install as standalone plugin
$ git clone git@github.com:dangerdespain/graphql-schema-loader.git [schema title]
$ cd [schema title]
npm install && rm .git && cd ../
Usage
var GraphQL = require('graphql');var schema = require('./graphql-schema-loader').schema var query, rootValue, variables, operationName graphql(schema, query, rootValue, variables, operationName).then(function(res){ if(res.errors){ } // Errors happened... GraphQL takes care of populating the API response but you can add more logic here. res = res // Handle your data and/or complete your response here return res}) // if this function pattern doesn't make sense, check out Promises! BluebirdJS is my favorite Promise lib.Advanced usage
My goal here was extendable schema definitions. Imagine being able to chain in a pre-built User Management/Stripe/Facebook Login schema to your primary app schema. I love the idea of being able to modularize and re-use chunks of schema endpoints and functions and hope that this catches on. This will be how I plan to build my GraphQL plugins from now on.
var utils = require('./graphql-schema-loader').utils utils = { collectObjects : function(){ // Smart-load and collect the items in the objects directory. }, collectMutations : function(){} collectQueries : function(){} extendSchema : function(schemaObjects={}){ // Builds the schema from the objects/queries/mutations directories. // If schemaObjects is included, this extends that schema with the new objects, queries, and mutations. }, compileSchema : function(schemaObjects={}){ // Calls extendSchema and returns a GraphQL Schema Object // If schemaObjects is included, this extends that schema with the new objects, queries, and mutations before creating the Schema object. This should be the last method called if chaining schemas. }}This module can easily be extended to dynamically generate schemas from a set of inputs, or to pass in a seeded schema object set.
