vulcanjs schemas&& collections

一张参考图

vulcanjs schemas&& collections

说明

从上图我们可以方便的看出schmea 能做的事情

  • Generate a GraphQL equivalent of your schema to control your GraphQL API.(生成 graphql api)
  • Control permissions for accessing and modifying data.(访问控制)
  • Generate forms on the client.(client 以及表单生成)
  • Validate form contents on submission.(数据校验)
  • Auto-generate paginated, searchable datatables.(自动生成分页,查询)
  • Auto-generate smart cards for displaying individual documents.(智能卡生成)
  • Add callbacks on document insert or edit.(数据添加,编辑时候的回掉)

参考例子

  • schema

    类似graphql-yogo 以及graphql-js 的schema 定义

const schema = {
// default properties _id: {
type: String,
optional: true,
canRead: ["guests"]
},
createdAt: {
type: Date,
optional: true,
canRead: ["guests"],
onCreate: ({ newDocument, currentUser }) => {
return new Date();
}
},
userId: {
type: String,
optional: true,
canRead: ["guests"],
resolveAs: {
fieldName: "user",
type: "User",
resolver: (movie, args, context) => {
return context.Users.findOne(
{ _id: movie.userId },
{
fields: context.Users.getViewableFields(
context.currentUser,
context.Users
)
}
);
},
addOriginalField: true
}
}, // custom properties name: {
label: "Name",
type: String,
optional: true,
canRead: ["guests"],
canCreate: ["members"],
canUpdate: ["members"]
},
year: {
label: "Year",
type: String,
optional: true,
canRead: ["guests"],
canCreate: ["members"],
canUpdate: ["members"]
},
review: {
label: "Review",
type: String,
optional: true,
control: "textarea",
canRead: ["guests"],
canCreate: ["members"],
canUpdate: ["members"]
}
};
  • 创建collection

    实际上上就是graphql api schema 定义以及解析处理

const Movies = createCollection({
typeName: "Movie",
schema,
resolvers,
mutations
});
