一張參考圖

說明

從我們可以方便的看出schmea 能做的事情

• Generate a GraphQL equivalent of your schema to control your GraphQL API.（產生 graphql api）
• Control permissions for accessing and modifying data.（存取控制）
• Generate forms on the client.（client 以及表單產生）
• Validate form contents on submission.（資料校正）
• Auto-generate paginated, searchable datatables.（自動產生分頁，查詢）
• Auto-generate smart cards for displaying individual documents.（智慧卡產生）
• Add callbacks on document insert or edit.（資料添加，編輯時候的回掉）

參考例子

• schema

  類似graphql-yogo 以及graphql-js 的schema 定義

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"]  }};

• 建立collection

  實際上上就是graphql api schema 定義以及解析處理

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