如何保持GraphQL API整洁?
我有这个简单的端点有三种可查询的类型,并保持整洁的文件夹结构,如:
/api
|--/entry
|--/types.js
|--/queries.js
|--/mutations.js
|--/category
|--/types.js
|--/queries.js
|--/mutations.js
|--/service
|--/types.js
|--/queries.js
|--/mutations.js
|--index.js
index.js是我定义根变异和查询的地方,这需要我明确地引用我的类型,查询和突变,所以显然这个文件会随着我添加新类型而增长,这有点挫败了分裂点他们首先在不同的文件夹中。
// src/routes/api/index.js
const LOGGER = require('../../logger')('routes/api');
const EXPRESS_GRAPHQL = require('express-graphql');
// returned when requiring this module
const routes = function (handler) {
LOGGER.log('info', 'Setting up api routes.');
const {
GraphQLSchema,
GraphQLObjectType,
} = require('graphql');
const categoryQuery = require('./category/queries');
const {
updateCategory,
deleteCategory,
createCategory
} = require('./category/mutations');
const serviceQuery = require('./service/queries');
const {
updateService,
deleteService,
createService
} = require('./service/mutations');
const entryQuery = require('./entry/queries');
const {
updateEntry,
deleteEntry,
createEntry
} = require('./entry/mutations');
const RootQuery = new GraphQLObjectType({
name: 'rootQuery',
description: 'This is the root query which holds all possible READ entrypoints for the GraphQL API',
fields: () => ({
service: serviceQuery,
category: categoryQuery,
entry: entryQuery
})
});
const RootMutation = new GraphQLObjectType({
name: 'rootMutation',
description: 'This is the root mutation which holds all possible WRITE entrypoints for the GraphQL API',
fields: () => ({
updateCategory,
deleteCategory,
createCategory,
updateEntry,
deleteEntry,
createEntry,
updateService,
deleteService,
createService
})
});
const Schema = new GraphQLSchema({
query: RootQuery,
mutation: RootMutation
});
return EXPRESS_GRAPHQL({
schema: Schema,
pretty: true,
graphiql: true,
});
};
module.exports = routes;
我该如何避免?
答案 0 :(得分:0)
嗯,它根本没有达到目的 - 你在应用程序中很好地分离了关注点,index.js
增长的唯一原因是需要明确要求你所有的模块。
我们在遇到类似的问题时遇到了困难,最终为每个模型目录(entry/
,category/
,service/
)包含的内容以及导出模块的内容设置了严格的界面。多亏了这一点,您可以编写一个整洁的包装函数,在启动时动态列出所有模型目录并尝试加载它们,期望所述接口。多亏了这一点,您根本不必在index.js
中编写任何新代码。您只需复制一个目录,实现导出的函数,它们会在应用程序启动时自动加载。
请记住向您的加载程序添加漂亮的错误记录,以避免在您意外破坏接口合同时出现神秘错误。
