@tsdiapi/cron v0.1.0

Cron Scheduler Plugin for TSDIAPI-Server

TSDIAPI-Cron is a plugin for the TSDIAPI-Server framework, designed to simplify scheduling and managing cron jobs in TypeScript projects. It integrates seamlessly with the framework and utilizes node-cron for precise task scheduling.

Features

• Declarative Cron Task Definition: Define cron tasks using a decorator (@CronTask).
• Manual Cron Task Registration: Dynamically register cron tasks at runtime.
• Integration with TSDIAPI-Server: Automatically initialize and manage tasks within the framework's lifecycle.
• Customizable Options: Add metadata like names and descriptions for better task management.
• Scalable Architecture: Easily handle both predefined and dynamic cron jobs.

Installation

npm install @tsdiapi/cron

or use @tsdiapi/cli to add it to your project:

tsdiapi plugins add cron

Code Generation

The TSDIAPI-Cron plugin includes a generator to streamline cron job creation. Use the tsdiapi CLI command to generate cron job files automatically:

tsdiapi generate cron

This command will create a new cron job with the necessary structure, including decorators and scheduling logic. You can specify the schedule and customize the task logic according to your needs.

Getting Started

Define a Cron Task

Use the @CronTask decorator to define a cron job:

import { CronTask } from "@tsdiapi/cron";
import { Service } from "typedi";

@Service()
export class TestCron {
  @CronTask("*/5 * * * * *", {
    name: "testTask",
    description: "Test cron task",
  }) // Every 5 seconds
  async testTask() {
    console.log("Executing test cron task");
  }
}

Register the Plugin

Add the plugin to the createApp function of your TSDIAPI-Server application:

import { createApp } from "@tsdiapi/server";
import CronPlugin from "@tsdiapi/cron";

createApp({
  plugins: [new CronPlugin()],
});

Configuration Options

The plugin supports the following configuration options:

PluginOptions

Example usage:

import CronPlugin from "@tsdiapi/cron";

createApp({
  plugins: [
    new CronPlugin({
      autoloadGlobPath: "*.cron.ts", // Custom glob pattern
    }),
  ],
});

Plugin Lifecycle Integration

TSDIAPI-Cron hooks into the plugin lifecycle to ensure tasks are started and managed efficiently:

• onInit: Initializes the plugin and loads cron tasks.
• afterStart: Automatically schedules all defined tasks.
• beforeStart: Custom pre-start logic can be added here if necessary.

Logs and Debugging

TSDIAPI-Cron logs information about scheduled tasks, including their names and schedules. Ensure your application's logger is properly configured to capture these messages for debugging purposes.
