Azure Durable Functions

This package provides a set of tools for working with Azure Durable Functions in TypeScript. It includes functions for interacting with Durable Functions through HTTP API.

Orchestrations API

Example

``ts
import { durableOrchestrations } from "@azure-utils/durable-functions";

try {
const response = await durableOrchestrations.start(
{
functionName: "myOrchestratorName",
input: { key: "value" },
},
{
baseUrl: "http://localhost:7071",
systemKey: "",
}
);

const id = response.result.id;
console.log(Orchestration started with ID: ${id});
} catch (error) {
console.error(error);
}
`

Entities API

Example

`ts
import { durableEntities } from "@azure-utils/durable-functions";

type State = { foo: string; bar: number };

try {
const state = await durableEntities.getState(
{
entityName: "myOrchestratorName",
entityKey: "value",
},
{
baseUrl: "http://localhost:7071",
systemKey: "",
}
);

console.log(State: ${state});
} catch (error) {
console.error(error);
}
`

DurableEntity class

This class is used to define a Durable Entity with a specific state and methods. It provides a way to manage the state of the entity and define actions that can be performed on it.

> This must be used in the Azure Functions app.

`ts
import { DurableEntity } from "@azure-utils/durable-functions/entity";

type MyEntityState = { foo: string; bar: number };
const defaultState: MyEntityState = { foo: "bar", bar: 0 };

export const myEntity = new DurableEntity("my-entity", defaultState, {
updateFoo: (input: { foo: string }) => ({ foo: input.foo }),
updateBar: (input: { bar: number }) => ({ bar: input.bar }),
});
