创建- gql- api

简化GQL打字和消费

开始

npx create-gql-api https://example.domain/graphql gql_api.ts

这会产生一个 gql_api.ts 文档.

import {
  createRequester,
  createSubscriber,
  createQuery,
  createMutation,
  createSubscription,
} from "./gql_api.ts";

const query = createRequester((query, variables) => {
  // Implement the GraphQL POST request with the
  // query, variables and any authentication you use
  // for your app
  return new Promise(() => {});
});

const subscribe = createSubscriber((query, variables, onMessage) => {
  // Optionally implement subscription handling
  // Call "onMessage" with new data
  // Return a disposer
  return () => {};
});

// Create a query by giving it a name and what fields to include
export const queryFoo = createQuery("Foo", {
  foo: {
    name: true,
    email: true,
  },
});
query(queryFoo);

// Query on simple values
export const queryBar = api.createQuery("Bar", {
  bar: [{ unit: "FOOTER" }],
});
query(queryBar);

// Query on object and lists
export const queryBaz = api.createQuery("Baz", {
  baz: [
    { id: "123" },
    {
      id: true,
    },
  ],
});
query(queryBaz);

// Query with variables
export const queryBazWithVars = createQuery(
  "BazWithVars",
  (vars: { id: string }) => ({
    baz: [
      { id: vars.id },
      {
        id: true,
      },
    ],
  }),
);
query(queryBazWithVars, { id: "123" });

// Mutations works like queries
export const mutateSomething = createMutation("Something", () => ({
  something: [{}],
}));
query(mutateSomething);

// Subscriptions
export const subscribeSomething = createSubscription(
  "Something",
  (vars: { id: string }) => ({
    something: [{ id: vars.id }],
  }),
);
subscribe(
  subscribeSomething,
  (data) => {
    // Handle the data
  },
  { id: "123" },
); // Returns disposer
