Wabe

Database ​

We have seen that Wabe offers a very rich GraphQL API for interacting with the data stored in the database. There is also another way, using the DatabaseController directly to execute your queries. This controller is accessible within the WabeContext (context.wabe.controllers.database).

Note: It is important to note, that the DatabaseController does not provide interfaces for interacting with "search," or with pointers and relations as offered by the GraphQL API.

Queries ​

You have the ability to retrieve one or multiple objects that match specific selection criteria. The fields parameter allows you to specify which fields of the object you want to retrieve.

Query one object ​

ts
const { id } = await context.wabe.controllers.database.getObject({
  className: "User",
  context,
  fields: ["id"],
  id: "userId",
});

Query multiple objects ​

ts
const res = await context.wabe.controllers.database.getObjects({
  className: "User",
  context,
  fields: ["id", "name"],
  where: { id: { equalTo: "userId" } },
});

const user = res[0];

Count the number of results ​

ts
const numberOfUser = await context.wabe.controllers.database.count({
  className: "User",
  context,
  where: { age: { equalTo: 20 } },
});

Mutations ​

You also have the ability to create / update / delete one or multiple object as you can do with GraphQL API.

Create one object ​

ts
const { id } = await wabe.controllers.database.createObject({
  className: "User",
  context,
  data: { name: "Lucas" },
  fields: ["id"],
});

Create multiple objects ​

ts
const res = await wabe.controllers.database.createObjects({
  className: "User",
  context,
  data: [{ name: "Lucas" }],
  fields: ["id"],
});

Update one object ​

ts
const { name } = await context.wabe.controllers.database.updateObject({
  className: "User",
  context,
  fields: ["name"],
  id: "userId",
  data: { age: 20 },
});

Update multiple objects ​

ts
await context.wabe.controllers.database.updateObjects({
  className: "User",
  context,
  fields: ["name"],
  where: { name: { equalTo: "test" } },
  data: { age: 20 },
});

Delete one object ​

ts
await wabe.controllers.database.deleteObject({
  className: "User",
  id: "userId",
  context,
  fields: [],
});

Delete multiple object ​

ts
await wabe.controllers.database.deleteObjects({
  className: "User",
  where: { name: { equalTo: "Lucas" } },
  context,
  fields: [],
});
