Graphql模板运行时工具,自动生成标准模板和Typescript类型, 配合Redux-Model实现graphql请求。
- 只需写一次,Graphql语法和Typescript同时拥有
- 自动收集参数
- 自动识别参数基础类型
- 单一职责,只生成标准graphql字符串
- 支持所有graphql语法
yarn add @redux-model/graphql
import { Model } from '@redux-model/react';
import { types, graphql } from '@redux-model/graphql';
const getUserTpl = graphql.query({
getUser: {
id: types.number, // number
name: types.string, // string
bankAccount: { // object
id: types.number,
branch: types.string.number, // string | number
},
}
});
// console.log(getUserTpl.toString());
// 生成模板:
// query GetUser {
// getUser {
// id
// name
// bankAccount {
// id
// branch
// }
// }
// }
type Response = {
data: typeof getUserTpl.type;
};
interface Data {
list?: Response['data'];
};
class TestModel extends Model<Data> {
getUser = $api.action(() => {
return this
.post<Response>('/graphql')
.graphql(getUserTpl)
.onSuccess((state, action) => {
state.list = action.response.data;
});
});
protected initialState(): Data {
return {};
}
}
const tpl = graphql.query({
getUser: {
id: types.number,
logs: types.fn(['page: Int!', 'pageSize as size: Int'], types.array({
id: types.number,
title: types.string,
})),
}
});
// 生成模板:
// query GetUser ($page: Int!, $size: Int) {
// getUser: {
// id
// logs (page: $page, pageSize: $size) {
// id
// title
// }
// }
// }
// 在模型中使用
type Response = {
data: typeof tpl.type;
};
type Data = Response['data'];
class TestModel extends Model<Data> {
getUser = $api.action((page: number, size: number = 10) => {
return this
.post<Response>('/graphql')
.graphql(tpl({
page,
size,
}))
.onSuccess((state, action) => {
return action.response.data;
});
});
protected initialState(): Data {
return {};
}
}
const fragment1 = graphql.fragment('User', {
name: types.string,
});
const tpl = graphql.query({
getUser: {
id: types.number,
...fragment1,
}
});
// 生成模板:
// query GetUser {
// getUser: {
// id
// ...UserFragment
// }
// }
//
// fragment UserFragment on User {
// name
// }
const tpl = graphql.query({
getUser: {
id: types.number,
...types.on('User', {
name: types.string,
}),
...types.on(['Hero', 'Thief'], {
age: types.number,
}),
}
});
// 生成模板:
// query GetUser {
// getUser: {
// id
// ... on User {
// name
// }
// ... on Hero {
// age
// }
// ... on Thief {
// age
// }
// }
// }
生成的模板和内联片段一样,但是在类型上是互斥的
const tpl = graphql.query({
getUser: {
id: types.number,
...types.union(
types.on('User', {
kind: types.custom<'User'>(),
name: types.string,
age: types.number,
}),
types.on('Admin', {
kind: types.custom<'Admin'>(),
name1: types.string,
age1: types.number,
}),
)
}
});
// 生成模板:
// query GetUser {
// getUser: {
// id
// ... on User {
// kind
// name
// age
// }
// ... on Admin {
// kind
// name1
// age1
// }
// }
// }
您可以通过判断来确定哪个字段存在
if (getUser.kind === 'User') {
// getUser.name
// getUser.age
} else if (getUser.kind === 'Admin') {
// getUser.name1
// getUser.age1
}
if ('age' in getUser) {
// getUser.name
// getUser.age
} else if ('age1' in getUser) {
// getUser.name1
// getUser.age1
}
const tpl = graphql.query({
getUser: {
id: types.number.include('test: Boolean'), // number | undefined
logs: types.skip('other: Boolean').object({ // object | undefined
id: types.number,
title: types.string,
}),
}
});
// 生成模板:
// query GetUser ($test: Boolean, $other: Boolean) {
// getUser: {
// id @include(if: $test)
// logs @skip(if: $other) {
// id
// title
// }
// }
// }
