介绍

这是一个轻量级的框架来帮你快速搭建一个GraphQL服务器。框架的主要目标是减少你的代码量，节省你的时间，同时给你足够的自由度。

思想

• 大幅度减少CRUD（增删改查）的代码量。
• 它是代码而不是黑盒子，你拥有完全的控制权，例如你可能想部署到Serverless上。
• 不需要学很多新的语法。
• 容易加入到你现有的项目。
• 支持所有knex支持的数据库。
• 对于超级复杂的用户需求，你可能还是要直接用knex来充分发挥sql的性能。

它是如何工作的

你定义一个model. 这个库会产生常用的GraphQL schema, resolvers代码。它还集成了一个编译器来把GraphQL的Search Query编译成knex Query, 来支持复杂的搜索查询(filter, groupBy, join, aggregations, nested fields等)。你可以继承框架提供的MobelBase来搭建你的Model逻辑。你也可以把model当成你的数据库访问层，在你的任何业务代码中调用它来访问你的数据。

特性

• logic generation for schema
• logic generation for common resolvers
• support queries: get, list(search by filters)
• support mutation: insert, delete, update, bulk insert, bulk delete, bulk update
• support common where filters: =, <>, >, <, between, in, or, and, etc.
• support common aggregations: groupBy, having, sum, avg, min, max, count, distinct, etc.
• support common components in a query: offset, limit, order by, etc.
• support nested objects queries
• no N+1 problem for common queries
• coexists with your current code, custom schema, custom resolver.
• it does not care if you are using graphql-server, graphql-lambda, or graphql-express, etc.

Compared to ...?

There are some other libraries/tools/services that you may want to check: such as hasura, prisma, postgraphile, joinmonster, etc. They have different goals and different philosophies. Given everything is evolving fast, we will not do a detail comparison here.
